Sinochem News Network News On July 7, the Shell pulverized coal gasification low water/gas sulfur-resistant conversion unit of Henan Coal Industry Group Zhongyuan Dahua Company was successfully started. After the transformation of the unit, the annual economic benefit of saving medium-pressure steam alone is nearly 50 million yuan, showing the energy-saving advantage of the process.
The unit adopts the pulverized coal gasification-low water-gas ratio sulfur-resistant conversion process developed by Qingdao Lianxin Chemical Co., Ltd. The operation results show that: the entire conversion process does not require the addition of steam, and when the load is 60%, at least 35 tons/hour of steam can be saved; the first conversion furnace runs smoothly, the operation is simple, and the process conditions are greatly relaxed. Due to the low water/gas, the amount of condensate in the subsequent process is also greatly reduced. At the same time, the process condensate can be directly sent to the sewage treatment system, reducing the operating cost of the process condensate pump.
