摘要
精馏是化工、石化、医药等过程的重要单元操作 ,其能耗约占化工生产的 60 % ,其节能途径包括采用新型高效分离技术、新型塔板、新型高效填料等。这些技术在甲醇工业中应用后 ,得到扩产 5 0 %～ 15 0 %、节能3 0 %～ 5 0 %的效果 ,技术改造的投资回收期一般在 1～
Rectification is an important unit operation in the chemical, petrochemical and pharmaceutical industries, its energy consumption takes about 60% in chemical production, and its energy-saving means include the adoption of a new-type of high-effiency separation technology, a new type of trays and a new type of packings. The use of these technologies in the methanol industry brings about an increase in output by 50%～150%, a decrease in energy by 30%～50% and a period for the recovery of investment in technical renovation of 1～3 months in general.
