Coal chemical process compressor inlet gas dust removal and tar removal
In the production process of modern coal chemical industry, the compressor is often required to pressurize after the purification of coal gas. A small amount of tar, dust and other impurities in the gas are easy to block the compressor valve, affecting normal production.
The technology of high gravity dust removal and tar removal has the following characteristics:
(1) Realize high-precision purification, and the concentration of tar and dust can be reduced to below 5mg/m ³;
(2) The liquid usage is small, and the gas-liquid ratio during operation can reach around 2000;
(3) The gas phase pressure drop is small, below 800Pa;
(4) Gas making circulating water can be used as a washing solution, which is convenient and reliable.
This technology is applied to the 200000 ton/year synthetic ammonia compressor inlet semi water gas dust removal technology renovation project of Guizhou Kailin Xifeng Synthetic Ammonia Phase I. Under the working condition of an inlet dust content of about 60mg/m ³, the dust removal rate can reach over 90%, and the purification footprint content is less than 5mg/m ³, ensuring the long-term stable operation of the compressor.
This technology can be widely applied to the deep purification process of compressor inlet gas in projects such as ammonia synthesis, coke oven gas to methanol production, and coal to hydrogen production.
