苯乙烯抽提技术配套乙烯工艺

Styrene Extractive Distillation Technology(STED) Supporting Ethylene Process

苯乙烯抽提技术(STED)配套乙烯工艺可降低上下游装置的能耗物耗,提升二甲苯品质,裂解副产物苯乙烯有燃料级提升到化学品级,具有客观的经济效益。目前,该技术已日益成熟,装置运行稳定,不会对上下游工艺造成影响。

Styrene Extractive Distillation Technology （STED） supporting Ethylene process, it will reduce the energy consumption and material consumptions of the upstream and downstream device. To improve the quality of xylene and Styrene of the by-products of Ethylene from the fuel level ascending to chemistry grade. It has the objective economic benefits. At present, the technology has been increasingly mature and process operation stability. It does not affect the upstream and downstream processes.
