How much room is there for further development in coking?

2009-04-05View Original

Thread Content

Dear sea friends: I’ve heard recent reports that **the regulations regarding coking projects are becoming stricter. Some people say that no new coking projects will be established in the future, and if any are built, they will be on a large scale. Are there any experts among you in this field? Share your insights!

There might certainly be some projects under construction; the key lies in your factory’s public relations capabilities and its actual strength

It is still necessary to move towards larger scale and modernization, make more use of weakly caking coal, and adopt environmentally friendly coke ovens.

At present, there is little room for development, as China’s coke production is already at capacity, and **exports are restricted in order to strengthen energy control. Let’s wait until all those outdated coke ovens are shut down before moving forward.

Once the financial crisis passes and demand for steel increases, opportunities for the development of coking will arise again.

From the perspective of resource conservation and environmental protection, coking has been condemned to death; it is merely surviving by relying on its economic benefits. If the residue hydrogenation process can overcome the problem of bed pressure drop, or if the slurry-bed residue hydrogenation process can be successfully industrialized, then its prospects will become even worse, hehe~

Due to the oil crisis, developing coal chemical and coking industries can serve as a substitute for some oil, but coal resources are also limited; therefore, the coking industry is subject to restrictions as well.

The transition from a free economy to a competitive economy comes at a cruel cost. In the future, there will be more coke than stones

**It can be seen that the coke supply is already saturated. The approval process for new coke oven projects is very strict; under normal circumstances it is indeed difficult to approve new projects. However, if environmental impact assessments, safety evaluations, and various connections are properly handled, it is still possible to get approval by citing technical innovation and the goal of becoming the best in the country.

I hope for better development in coking. Traditional coking methods have almost reached their limits, and it requires the joint efforts of everyone to overcome the existing techniques and bring about a new era for coking.

There’s no more room for development. Over-saturated. **It’s under control now. It’s better to develop high-tech and fine chemical industries.

Thank you all for your strong support. It’s been a long time since I last visited; reading everyone’s discussions has been very beneficial to me. It seems that in the coking industry, it’s not only necessary to scale up operations but also to extend the industrial chain

Small-scale coking meets most of the demand, and industry consolidation by larger enterprises is still needed. Entities of a larger scale do have considerable room for growth.

This question is actually very simple. If you were the boss, would you invest in the coking industry under the current circumstances? Only a fool would invest without making a profit. The reason is obvious: over-saturation, as at least 50% of the production capacity has not yet been fully utilized. Approval isn’t the issue; the key is that **the imbalance in industry development has also been recognized, and appropriate regulation is needed simply to cool down those overly ambitious bosses.**

For some time after the reform and opening up, a great number of enterprises were established at that time. Through a certain period of development, materials move from a situation where supply falls short of demand (when there is a shortage and people have to fight for what’s available) to one where supply exceeds demand; at this point, the market begins to undergo a shift from quantitative changes to qualitative changes, and people start seeking products that are both inexpensive and of high quality. Then, some enterprises with low quality and high costs will inevitably be shut down. Personally, I think the current coking industry is a bit similar to that one. The industry will certainly develop, but what is needed is the elimination of outdated facilities; new projects must be beneficial in terms of quality, cost, and environmental protection, and must be compatible with large blast furnaces.

Take a look at this: there is currently a severe overcapacity, and it’s time to eliminate outdated production capacity and accelerate mergers and reorganizations. All small coke-producing enterprises will be shut down, with most of them being brought under the control of 10 coke production parks. ”On May 15, such a message was conveyed at the training course on the adjustment and revitalization plan for Shanxi’s coking industry, drawing significant attention from the coking sector.   The plan states that within two years, Shanxi’s coke production capacity will be kept at around 140 million tons. Within six years, this figure will drop to 120 million tons. Some coking enterprises are doomed to suffer from operational difficulties, and what’s worse, some of them will find themselves in a desperate situation, truly in a tough spot.   Contradictions become apparent. It is undeniable that the coking industry has made significant contributions to the sound and rapid development of our province’s economy. However, the contradictions and problems resulting from the industry’s long-term extensive development are becoming increasingly evident.   The first issue is overcapacity. By the end of 2008, the total coke production capacity across the province was 159.68 million tons, yet the capacity utilization rate was not high.   There are over 270 coking enterprises in the province, with an average production capacity of only 590,000 tons per enterprise. Only 10 enterprises have a coke production capacity of over 2 million tons, accounting for less than 15% of the total capacity in the province. It is an undeniable fact that industry concentration is low. Another similar issue is the low level of industrial technology. Among the more than 290 coke ovens in the province, over 220 of them have a carbonization chamber height of 4.3 meters, accounting for 76%, while those with a carbonization chamber height of over 6 meters make up less than 3% of the total.   In response to the unreasonable layout of the coking industry in Shanxi, the province has carried out cleanup and rectification efforts; many coking enterprises with inappropriate locations or outdated facilities have been shut down. However, there are still more than 60 counties (cities, districts) in the province that have coking plants, and the problem of scattered distribution remains severe.   In the coking industry chain, many resources can be utilized, but in 2008, approximately 4 billion cubic meters of excess gas from coke ovens across the province were still burned directly without being put to comprehensive use. The tar recovery rate is 90%, and the crude benzene recovery rate is 85%. The problem of waste from coke by-products has not been completely resolved, the deep processing of chemical products has not yet reached a commercial scale, and the tasks of energy conservation and emission reduction remain arduous.   Although Shanxi has taken numerous measures to address the pollution issues associated with its coking industry, data shows that a significant number of coking enterprises in the province still lack the necessary facilities for biological wastewater treatment and gas purification; or even when such facilities do exist, they often fail to operate properly. Amidst numerous contradictions, Shanxi has also begun to take action. At the training session, Ma Yunxia, head of the Energy Department of the Provincial Economic Commission, revealed that the province would address each of the aforementioned issues one by one.   High degree of concentration: “Next, a comprehensive assessment will be carried out on the coke production parks located in Lüliang, Linfen and other areas. Various factors such as raw materials, water resources, pollution reduction measures, and transportation capacity will be taken into account to identify ten industrial parks for a circular economy in the coke industry. These parks will be given strong support so that they can serve as models for the coke industry in our province to achieve energy conservation, emission reduction, and the development of a circular economy.” Vigorously carry out the replacement of coke production capacity, and build super-large-scale coking projects with technology at the international advanced level and a production scale that offers economic efficiency. ”Ma Yunxia said.    “Among the ten coke production parks located in Lüliang, Linfen, Jinzhong, Changzhi, and Yuncheng, the Jiexiu and Lingshi parks in Jinzhong are the largest in scale. ”Nie, the head of the Energy Section at the Jinzhong Municipal Economic Commission, told a reporter from the Shanxi Youth News that the coking production capacity of the Jiexiu industrial park should be over 7 million tons, while that of the Lingshi industrial park is also over 6 million tons. ”   “In principle, no new coke plants will be established in the future to reduce pollution sources. Other existing coking projects located in scattered locations will be phased out through capacity replacement. ”The aforementioned person said.   Optimize the layout of the coking industry by transferring coking production capacity to centralized coking areas through the phasing out of outdated facilities and capacity replacement. “By 2011, the coking capacity of the top ten coking parks in the province accounted for over 40% of the province’s total coking capacity. By 2015, the coking capacity of the concentrated coking areas in the province accounted for over 80% of the province’s total coking capacity. No new coking clusters will be established across the province. ”   The plan states that, centered around new coking projects with capacities of 10 million tons and 5 million tons each, and taking into account the availability of raw material resources and transportation capabilities, a number of large-scale projects for the comprehensive utilization of coke oven gas, as well as large-scale projects for tar processing and crude benzene refinement, will be established. Furthermore, plans are in place to develop projects for the further refinement of tar and benzene-based chemicals.   Eliminating the outdated Since the rectification efforts began in 2004, significant progress has been made in adjusting the industrial structure of coal coking in Shanxi. The province has phased out nearly 60 million tons of outdated coking capacity; the proportion of coke produced using ovens with a height of 4.3 meters or more reached 90.6%, and key leading enterprises have been equipped with facilities for chemical product recovery and pollution control.   “Among Shanxi’s key industrial sectors, there is a need to phase out outdated production capacities, and the coking industry leads far ahead in this regard. ”A staff member from the Industry Department of the Shanxi Provincial Economic Commission told a reporter from the Shanxi Youth Daily, “During the 11th Five-Year Plan period, the coking industry had already completed its task of phasing out outdated production capacity.” ”   Data shows that by the end of 2008, the total coking capacity across the province was 159.68 million tons; the capacity utilization rate was still low, and the degree of industry concentration was low as well. With over 270 coking enterprises in the province, each enterprise had an average capacity of only 590,000 tons. Only 10 enterprises have a coke production capacity of over 2 million tons, accounting for less than 15% of the total provincial capacity; there is still a significant amount of outdated production capacity.   “After completing its ‘tasks’, the coking industry will continue to phase out its outdated production capacity every year. ”   By the end of 2011, the total coking capacity across the province was to be kept below 140 million tons, with around 20 million tons of coking capacity that used outdated technology and equipment and did not comply with the policies governing the coking industry to be phased out. By 2015, the total coking capacity across the province was to be kept below 120 million tons. Meanwhile, on top of what was achieved in 2011, another 40 million tons of coking capacity that did not meet the required standards and was not included in the **admission list was to be phased out over time.   This specific standard also sets clear requirements: coke ovens with a carbonization chamber height of less than 4.3 meters must be phased out by the end of 2010 (excluding rammed coke ovens with a carbonization chamber height of 3.2 meters or more). By the end of 2010, coke ovens with a carbonization chamber height of 4.3 meters (including rammed coke ovens with a carbonization chamber height of 3.2 meters or more) should meet the requirements set out in the \"Access Conditions for the Coke Industry (2004 edition)\". Enterprises that fail to meet these requirements by that time should, in principle, be considered for capacity replacement and should be shut down in phases by 2015. Strict measures such as cutting off water, electricity, operations, loans, and coal supply shall be implemented against the coke oven projects on the phase-out list.   The plan states that by 2011, 20 million tons of capacity replacement projects for large-scale coking should be established. By 2015, a number of super-large coking enterprises using internationally advanced furnace designs with production capacities of 10 million tons and 5 million tons each would be developed; the number of coking enterprises would be reduced to less than 60. The combined production capacity of the top 10 coking enterprises in the province would account for over 60% of the total provincial production capacity.   Survival Test: According to the plan, by 2011, the energy consumption per ton of coke produced in the province’s coking processes was to be reduced to below 150 kilograms of standard coal. Tar, crude benzene, and residual coke oven gas are all recycled. By 2015, the energy consumption per ton of coke produced in the province’s coking processes was reduced to below 120 kilograms of standard coal. Pollutant emissions across the entire industry meet **the second-level standards for clean production or higher.   Ma Yunxia said, “By 2011, this energy-saving target could still be achieved by the coke manufacturers in the province.” By 2015, it would become difficult to bring the energy consumption per ton of coke produced in the entire province below 120 kilograms of standard coal. ”   “It is extremely difficult for any enterprise to survive. During this period, people have been constantly calling and coming by to ask what to do next ”Ma Yunxia said, “To improve social benefits, we need to understand that success is achievable through transformation.” ” Therefore, in terms of policy, the plan also provides detailed guidance at both macro and micro levels. “Implement a circular economy, extend the industrial chain, recycle by-products and waste from the production process, and improve the overall utilization rate of resources and energy ; Install efficient pollution control facilities to control and reduce pollution emissions. ”Ma Yunxia said.   In addition, enforce strict regulations on energy consumption and environmental protection. In accordance with **energy-saving and environmental protection regulations and policies, strict targets for energy consumption and pollutant emissions are established. Strengthen the monitoring of energy consumption and pollutant emissions. Implement a elimination system for those at the bottom in terms of energy consumption and pollution control. Implement online monitoring of pollutant emissions, and strengthen daily supervision over pollutant emissions in the coking industry.   “The environmental protection facilities of all coking enterprises in the province, particularly those related to wastewater treatment, flue gas desulfurization, and smoke and dust removal, must be gradually improved and brought into proper operation to ensure compliance with emission standards. ”   For some companies that fall short of the standards, this is nothing short of a life-or-death challenge.
