Green methanol preparation system and method coupled with direct air carbon capture and utilization
The invention provides a green methanol preparation system and method coupled with direct air carbon capture and utilization. The system comprises a direct air carbon capture unit, an electrolyzed water unit, a green methanol preparation unit and an energy gradient utilization control unit. The direct air carbon capture unit captures carbon dioxide in the atmosphere in a strong alkaline solution absorption mode, and the carbon dioxide is used as a raw material to be mixed and react with hydrogen generated by the water electrolysis system to generate liquid-phase crude methanol and part of gas which is not completely reacted. The liquid-phase crude methanol is reprocessed by a subsequent two-stage distillation tower to obtain green methanol; part of gas which is not completely reacted is divided into two parts through the energy gradient utilization control unit, one part is input into the direct air carbon capture unit for combustion, and the other part is input into the methanol preparation reactor for circulation. Self-sufficiency of energy is achieved, and the utilization rate of raw materials is increased.
本发明提供一种耦合直接空气碳捕集与利用的绿色甲醇制备系统及方法。系统包括直接空气碳捕集单元、电解水单元、绿色甲醇制备单元以及能量梯级利用控制单元。直接空气碳捕集单元通过强碱性溶液吸收的方式将大气中的二氧化碳进行捕集，并以此为原料，与电解水系统产生的氢气混合并反应，生成液相粗甲醇以及部分未完全反应的气体。液相粗甲醇通过后续两级蒸馏塔的再加工获得绿色甲醇；部分未完全反应的气体通过能量梯级利用控制单元分成两部分，一部分输入直接空气碳捕集单元进行燃烧，另一部分输入甲醇制备反应器进行循环。本发明实现能量的自给自足，提高原料的利用率。
