主 题：F-T synthesis α-Olefns DWC Heat-integrated distillation Process design
摘 要：The development trend of Fischer–Tropsch(F–T)technology is to develop high value-added *** separation of linearα-olefns with low cost is an efective ***,the lack of thermodynamic data and the huge energy consumption are the two main problems restricting the development of the separation *** thermodynamic data of the key components(1-dodecene and n-dodecane)in the F–T product were *** Wilson binary interaction parameters of the key components were ***,one traditional distillation column sequence and two dividing wall column(DWC)sequences were designed to separate the F–T heavy oil to obtain narrow fractions with diferent carbon ***,the obtained fractions of C10 and C12 were simulated to obtain 1-decene and 1-dodecene,*** was a traditional distillation and a diferential pressure thermal coupling distillation *** separating 95.0%purity 1-decene and 1-octene,the direct DWC process and diferential pressure thermal coupled distillation are an excellent combination,which can reduce the energy by 33.1%(i.e.,11,286 kW)and total annual cost by 15.9%(i.e.,3.96×10^(6)$)compared with traditional distillation.
