Over the past two years, methanol prices have remained stable, but upstream raw materials such as natural gas, coal, and oil are at high prices, resulting in losses for methanol producers. In production facilities, the distillation system accounts for the majority of energy consumption; it is therefore essential to reduce the specific consumption of methanol vapor. Currently, the energy consumption of various enterprises using the conventional three-tower process is around 1.1 tons of steam per ton of purified methanol, and the energy-saving effect of using steam condensate to supply heat to the pre-tower is not very significant. Currently, a company in Xinjiang and a company in Yunnan are using a new coupling process that eliminates the need for additional tower equipment; as a result, the steam consumption per unit of pure methanol has been reduced to around 0.85–0.9 (with ethanol levels below 20 and water levels below 50). This results in a significant reduction in energy consumption and substantial cost savings. But this is by no means the lowest target for energy conservation and consumption reduction; so what is the minimum possible level of methanol consumption? It is currently known that Tianjin Aozhan Xingda can achieve levels below 0.7, which is already quite impressive; is it possible to achieve even lower energy consumption?
