What are the reasons for methanol synthesis? 2015.09.06--09.13
The increase in steam consumption for methanol production is mainly caused by the following: after the operation of the dual-structure facility, some of the oxygen or gas generated by the C# air separation unit and the D# gasifier enters the methanol and synthetic ammonia systems. Therefore, when achieving an overall steam balance across the entire plant, it is necessary to allocate some steam to these two units, which results in an increased consumption of methanol steam
I feel that steam consumption is mainly related to the production load and the recovery of heat energy during production.
The steam consumption in methanol distillation is affected by various factors: the composition of the distillation feed, the feed temperature, the heat exchange efficiency of the heat exchangers, environmental conditions, and the level of operational expertise； Synthesis mainly affects the quality of crude methanol. Personal opinion
Steam consumption is primarily influenced by factors such as the moisture content of the feedwater, the impurity content in the feed, and the load level; synthesis, on the other hand, depends mainly on the quality and concentration of crude methanol
Raw material composition, requirements for product purity, design of distillation internals, hierarchical recovery and utilization of heat
