China’s first coal chemical power generation project designed by our institute has been put into operation

Is Huisheng’s CO intended for BP and Celanese’s acetic acid projects? 290,000 tons per year of CO should only be sufficient to supply an acetic acid plant with a capacity of 500,000 tons per year. What is the price for supplying CO? Also, which design institute does the original poster work for? I’d love to have a chat if there’s a chance!

Congratulations, congratulations! May I ask which institution the poster is referring to with “our institute’s design”?

There are many enterprises that use the steam from coal chemical industries to generate electricity; for example, in Ningxia, Shaanxi, the Xinjiang Uyghur Autonomous Region, and the Inner Mongolia Autonomous Region, many coal chemical plants utilize waste heat for power generation, a practice that has existed since the last century

There are many that use coal chemical industry steam for power generation

Why is it that exhaust gas from coal chemical enterprises is rarely used for power generation? In fact, the amount of exhaust gas generated by these plants is quite large, but very little of it is used for power generation. What is the reason for this?

Replying to the person on floor 6. Useful components in the exhaust gases from the chemical industry are usually separated and utilized. The calorific value of these exhaust gases is generally low, making it uneconomical to use them for power generation.

Our institute is the Jiangsu Energy Conservation Engineering Design Institute; it specializes in the design of thermal power plants, heat networks, energy conservation assessments, and feasibility studies. I’m not quite familiar with the specific price of CO, as my main work involves their power generation projects.

The second-phase syngas project of Huisheng (Nanjing) Chemical Co., Ltd. has a total project investment of 760.5 million yuan, of which 18.1 million yuan is allocated to environmental protection measures (some of these environmental facilities make use of those already in place in existing projects), accounting for 2.38% of the total investment. The project covers an area of 210,000 m2. This project will be constructed by making full use of the existing utilities and infrastructure from Phase I. Upon completion, the company will achieve an additional production capacity of around 300,000 tons per year of CO, around 13,600 tons per year of hydrogen, and around 72,000 tons per year of syngas. The excess purified gas resulting from low-temperature methanol washing will be sent to the methanol synthesis unit in Phase 1, allowing the use of the existing capacity there to increase methanol production by around 100,000 tons per year ； At the same time, by utilizing the steam generated as a by-product of the heat recovery unit in this phase, as well as the additional steam produced by the methanol synthesis and sulfur recovery units in Phase 1, and by adding more generating units to the waste heat power generation project in Phase 1, the electricity generation capacity is increased by approximately 65 million kWh per year. The second Huisheng syngas production process includes a raw coal conveying and storage unit, a Texaco water-coal slurry gasification unit, a heat recovery unit, a low-temperature methanol washing unit, a CO cryogenic separation unit, and a PSA pressure swing adsorption unit. Furthermore, while ensuring the production levels of CO, hydrogen, and syngas, the excess purified syngas is sent to the first-stage methanol synthesis unit to increase methanol production ； The stripping gas generated by the stripper in the heat recovery unit of this project, as well as the H2S-rich acidic gas produced by the methanol regeneration tower in the low-temperature methanol washing unit, are treated using the sulfur recovery unit from Phase I. During that period, the world’s leading chemical company, German company Clariant, signed a contract for key raw materials for its factory in Nanjing, agreeing to purchase CO on a long-term basis from Huisheng (Nanjing) Chemical Co., Ltd. Serenis’ signing of this raw material procurement contract with Huisheng Company is aimed at preparing for the commissioning of the acetic acid project next year. In 2003, Seralis built an acetic acid plant in the Nanjing Chemical Industry Park, with an investment of $148 million. The plant has a production capacity of 600 kt/year, making it the largest of its kind in China and the second largest in the world. As a result, Huisheng Company will invest $95 million in the chemical park to build a 300 kt/a methanol and a 200 kt/a CO project.

The steam used for power generation as mentioned by the poster is likely to be at 0.5 MPA. How much electricity can be generated using such steam in a year? What is the total electricity consumption of a Wessing plant per year? The amount of steam required must be fairly small, right? What are the things to keep in mind when choosing this type of power generation equipment?

Are there any projects that rely primarily on coal for power generation while producing chemical products as a by-product?

We are also in the power generation business; we don’t know much about what the original poster is talking about. I hope you can provide a detailed explanation of this type of power generation

Could the original poster introduce this power generation technology? I’d like to learn about it.

I hope the original poster can provide all the relevant parameters, such as the coal processing capacity and the amount of by-product steam generated.
