The gasification process is a process in which coal is converted into syngas through a high temperature and high pressure reaction in a gasifier. Syngas contains a large amount of dust, which is purified by washing with water, and a large amount of suspended solids enter the water to form black water, which becomes grey water after decompression, cooling, flocculation and precipitation. Since a large amount of suspended solids and inorganic salts in coal ash enter the washing water during the washing process, and the water temperature is also high, the system deposits and scales quickly, resulting in reduced system load or unplanned shutdown.
The characteristics of Weliya coal chemical agent:
Complete product
Various flocculant and dispersant products can be provided to meet the requirements of different coal types and different water quality
Excellent technology
High temperature-resistant dispersants have been developed, which can have stronger suspended solids dispersing ability and scale inhibition ability, prolong system operation period, and help customers improve operation efficiency.
Weliya is able to solve the following problems:
Sedimentation: After the dirt is deposited, it will lead to blockage of washing towers, pipelines and other equipment, shortening the operation cycle
Suspended solids: After the black water is settled and reused, the suspended solids in it need to be reduced to reduce sedimentation.
