摘　　要：鉴于化工产品中C9芳烃与调和汽油市场价格差值较大,而我们石脑油加氢装置产的调和汽油中其C9A含量约为65%,未贯彻落实公司降本增效的主旨,提高装置经济效益,将利用前期大检修中的技改流程,将目前石脑油分馏塔的工艺参数进行调整,适当提高加氢C6-C8产品中的C9A含量,通过抽提分离出非芳,送至下游装置继续分离出C9芳烃,根据2023年9月装置运行结果,此次改动单月降本增效收益增加约为30万元人民币,此后装置将结合市场需求以及装置运行负荷继续调整,持续改进,将C9芳烃经济价值最大化挖掘。In view of the large market price difference between C9 aromatics in chemical products and blended gasoline,and the C9A content in blended gasoline produced by our naphtha hydrogenation unit is about 65%,the purpose of reducing cost and increasing efficiency of the company is not implemented,and the economic benefits of the unit are improved.The process parameters of the current naphtha fractionator will be adjusted by using the technical transformation process in the early overhaul,and the C9A content in the hydrogenated C6-C8 products will be appropriately increased.The non-aromatic is separated by extraction and sent to the downstream unit to continue to separate the C9 aromatics.According to the operation results of the unit in September 2023,the monthly cost reduction and efficiency increase of this change is about CNY 300,000.Since then,the device will continue to be adjusted according to the market demand and the operating load of the device,and continuous improvement will be made to maximize the economic value of C9 aromatics.
