In order to achieve the goal of environmental protection in the production process of methanol, the methanol plant has carried out a series of technological transformations in terms of energy conservation and emission reduction, energy recovery, and comprehensive utilization since its establishment. Among them, in order to prevent acid-rich sulfur gas from low-temperature methanol washing to pollute the air, the QC public relations team of the methanol plant synthesis workshop established a deep technical transformation of the device, which solved the bottleneck problem affecting the operation of the device, and used the Claus sulfur recovery device to make acid The gas was recovered and made into sulphur products sold in Ningxia and Shandong.
At present, sulfur products produced by the sulfur recovery plant of the methanol plant can completely treat the hydrogen sulfide gas discharged from the purification section, reducing the acid gas emissions by 440 cubic meters per hour; and producing about 35 tons of sulfur per month.
Shen Ning Methanol Plant Sulfur Recovery Pollution Control and Efficiency Improvement
Shenning Group's coal chemical branch company's methanol plant is the start project of coal chemical construction. After more than three years of operation, it not only achieves safe and stable production, but also recovers the sulfur from the production process, turning it into waste.
