Process configuration issue
Thread Content
Our factory’s compressors feature 4-stage compression, with a combined pressure of 5.4 Mpa. There are two options for the purification process. 1. In the self-compression two-stage purification process, with a pressure of 0.85 Mpa, the material passes through transformation, desorption, decarburization, and precision desorption in sequence before entering the compression three-stage stage. 2. In the self-compression three-stage purification process, the pressure is 2.1 Mpa; after transformation, degassing, decarburization, and final degassing, it proceeds to the compression four-stage process. That type will have lower energy consumption.
The topic is interesting; could you provide more details? Coarse syngas components? Product solution?
Before the transformation, the gas composition was approximately as follows: CO2: 7.0%, CO: 35%, H2: 54%, N2: 3%, CH4: about 1%. After transformation: CO: 24–26%, CO2: 12–14%. CO2 after decarburization: 3–5%; after further purification, it enters the third compression stage. The output from this stage is mixed with hydrogen to enter the fourth compression stage, where it forms fresh gas that is fed into the synthesis tower. Produce monohydric alcohols.
