【Abstract】 Double - effect triple - column process can produce methanol with higher quality and has advantages in energy saving. The properties of this new process is investigated and discussed in the paper through the simulation calculation and comparison on dual - column distillation, atmospheric triple - column distillation, and double - effect triple - column pressure distillation schemes, The result suggests that the double - effect triple - column process has great developing potentials.更多还原
