Main works

1

Coal gasification plant

Colin's pulverized coal gasification technology is used to gasify pulverized coal, water vapor and oxygen into crude coal gas, mainly including 2 pulverized coal gasifiers to produce effective syngas (CO + H2): 136072Nm3/h.

New plant

2

Purification plant

With the process of Two-stage isothermal conversion→Desulfurization and decarburization (Hualu low-temperature methanol washing process)→Separation (cryogenic separation and PSA hydrogen extraction), the plant will process effective gas 71260Nm3/h, which provide effective H290000Nm3/h and CO46000Nm3/h for subsequent production systems.

New plant

3

Sulfur recovery system

Located in the purification plant area, it is designed as a series. A combined and advanced sulfur recovery process is adopted, and the tail gas is sent to the boiler desulfurization unit to remove SO2. Under normal operating conditions of the device, the sulfur production is about 982.08 kg/h.

New plant

4

Ethylene glycol plant

It adopts the ethylene glycol technology of Sinotech Far East Company, which includes six units: esterification unit, carbonylation unit, DMO distillation unit, DMO hydrogenation unit, ethylene glycol distillation unit, and tail gas treatment unit. The total production capacity of the plant is 400,000 tons/year of ethylene glycol.
