In this paper,two flows of total isomerization process are introduced,and several aspects of this process are discussed including the characters of isomerized oil,isomerization catalyst and adsorbent,the feed projects of different feedstocks,the operational conditions and so on.
简单介绍了完全异构化工艺的2种流程,并对该工艺的以下几方面进行了分析:异构化油的特点、常用异构化催化剂的特点、常用吸附剂的特点、不同原料的进料方案和工艺操作条件等。
A Simulation of the absorption and stabilization system for two processes, cold flow feeding and cold-heat dual-flow feeding, in the FCC unit was carried out by using HYSYS simulative software of chemical engineering process.
根据模拟结果,对整个系统的工艺特性、能耗和吸收效果进行了全面分析,澄清了某些模糊概念,指出双塔流程冷进料工艺在总能量消耗、吸收效果和扩能增效方面均优于双塔流程双股进料工艺。
The cold-model experiments demonstrated two disadvantages of the traditional structure of feedstock injection-mixing zone in FCC riser, namely the particle phase backmixing and the non-uniformity of catalyst concentration in reactor catalyst-oil mixed phase.
通过冷模实验,揭示了在传统结构的催化裂化提升管进料混合段内存在两个问题,即颗粒相返混严重以及反应管中各处催化剂在油、剂混相中浓度分布不一致。
On the basis of existing delayed coker, the facilities have been set up to introduce CGO into the feedstock system, the operation mode has been modified and the unit feedstock has been altered with CGO during the late part time of a coker drum so as to increase the outlet temperature of the furnace by 10C ~ 20C Deep thermal cracking of CGO has been realized and single-pass conversion rate.
提出了有别于大循环比操作方式且更有效的降低蜡油收率的延迟焦化技术:在现有延迟焦化装置的基础上,增加焦化蜡油补入原料系统的设施,改变普通延迟焦化操作方式,在一个焦炭塔操作周期的后期一段时间内,通过切换焦化蜡油为装置进料,提高加热炉出口温度10～20℃,实现焦化蜡油深度热裂化,提高其单程转化率。
The feeding System of the heavy oil catalytic cracking unit with a capacity of 600,000 t/a in Shengli Petrochemical Plant was modified in order to meet the requirements of atmospheric residuum processing.
