Abstract: Combined with actual situation of the remaindering C4 fractions resources after etherification in refineries and the existing 2-propyl-1-heptanol (2-PH) process flow,technical analysis is performed on the reuse of unreacted C4 from the top of the C4 tower,the improvement of the hydroformylation reaction system by the hypergravity reaction process enhancement technology,and the purification and recovery of fusel by-products.A preliminary process optimization plan is proposed,and the feasibility of technical transformation for the existing plant is discussed,which provides a reference idea for the process optimization of other 2-PH plants in the future.
