利用流程模拟和夹点技术对水煤浆制甲醇装置的变换工艺进行了计算分析。水煤浆制甲醇装置的变换反应在较高的温度下进行即可使CO的变换总量满足工艺需求,同时可使副产蒸汽的压力等级由4.0 MPa(G)和0.5 MPa(G)提升为11.0 MPa(G)和0.5 MPa(G),增加的投资可在短期内收回。 Process simulation and pinch point technology were used to calculate and analyze the conversion process of methanol plant with CWS. Coal-water slurry methanol plant shift reaction can be carried out at higher temperatures so that the total conversion of CO can meet the process requirements while increasing the pressure level of byproduct steam from 4.0 MPa (G) and 0.5 MPa (G) 11.0 MPa (G) and 0.5 MPa (G), the increased investment can be recovered in the short term.
