Can the subsequent purification processes for Luchi gasification meet the required standards? And what is the impact on the ecosystem, especially in places like Xinjiang?
Thread Content
Currently, coal-to-natural gas projects are very popular in Xinjiang and Inner Mongolia, and many companies intend to use the Lurgi gasification technology; however, with this technology, wastewater is difficult to treat. What is the current situation regarding handling this issue in China, and what is the impact on the environment, especially in areas with fragile ecosystems such as Xinjiang and Inner Mongolia?
No one answered. Is the question I asked too simple?

Besides, these companies are usually located in remote areas, making it difficult for environmental authorities to keep an eye on them. Who will stop them from discharging pollutants secretly? The \"Meihua Monosodium Glutamate pollution incident\" is a good example of this; it’s a news report from Ifeng.com, not something I invented. Refer to: http://finance.ifeng.com/news/sp...01102/2811218.shtml. It’s a clear indication of a lack of corporate social responsibility – there’s really nothing to say……
Thank you for your answer; I think so too. However, the coal quality in Xinjiang is not suitable for producing water-coal slurry; therefore, Ruhchi or pressurized coal gasification methods must be used. At present, although there are many facilities for pressurized coal gasification, many of them cannot operate continuously for long periods, especially the Shell furnaces. GSP still lacks experience in large-scale commercial operation, and this is probably why many companies choose Luchi.
In today’s China, whether you meet the standards or not depends on your boss’s tactics! Besides, Xinjiang is so far away!
It goes without saying that the officials think that as long as certain standards are met, then they have been met
It can be reduced from over COD5000 to around 150; ammonia nitrogen and volatile phenols are within the specified limits, and the color intensity is 150 times. The effluent is used to replenish the circulating water. Don’t worry about the hardness level, or the moisture in the coal, or the condensed water from unreacted steam. The most important thing is that the phenol recovery and ammonia recovery in the upstream section can operate properly over long periods of time. If that section cannot function properly, it is necessary to reduce the amount of wastewater to be treated; and with a reduced treatment volume, the production load of the entire system must also be decreased, or else the wastewater will simply be released into the atmosphere, resulting in significant pollution.
