结合炼厂醚后C₄资源及现有2-PH工艺流程的实际情况，主要对C₄塔顶未反应C₄回用、超重力反应过程强化技术用于氢甲酰化反应系统改进以及杂醇副产品提纯回收等方面进行技术分析，同时提出初步工艺方案，并探讨了针对现有装置进行技术改造的可行性，为今后2-PH装置的工艺优化提供一种可借鉴的思路。

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.
