摘要
Abstract
The methanol recovery unit in an existing biodiesel plant was optimized in this paper by using a thermally integrated multi-effect distillation process.The comprehensive economic benefits and CO2 emissions were calculated and analyzed under different processes.By comparison,it was found that the total annual investment cost of heat integrated multi-effect distillation process is 28.33%lower than the conventional process,and the carbon emission is also 41.06%lower than the conventional process,which directly reflects that heat integrated multi-effect distillation is an important energy-saving and consumption reduction pathway.关键词
