摘要： A novel integrated olefin processing scheme is provided where olefins and paraffins are processed to produce high octane gasoline blending components. The integrated process involves the dehydrogenation of paraffin compounds to olefin compounds and the processing of olefins by hydroisomerization to produce hydroisomerate streams which are subsequently etherified. Those olefin compounds which are not etherified pass to an alkylation process where they are alkylated with branched chain paraffin compounds to produce an alkylate product.
摘要翻译：提供了一种新型的烯烃加工方案，其中加工烯烃和链烷烃以产生高辛烷值汽油调和组分。一体化方法包括将链烷烃化合物脱氢成烯烃化合物，并通过加氢异构化处理烯烃以产生随后醚化的加氢异构体物流。未醚化的那些烯烃化合物通过烷基化方法，其中它们用支链烷烃化合物烷基化以产生烷基化产物。

摘要： A system and/or process for removing water from an alkylation catalyst mixture of an alkylation process is disclosed. The process includes passing an alkylation reaction zone effluent to a settler for separation into a hydrocarbon phase and a catalyst mixture phase; passing at least a portion of the hydrocarbon phase, as a settler effluent stream containing alkylate, water, HF and volatility reducing additive, to a first separator; removing and condensing a first overhead stream from the first separator thereby forming an HF/water stream; passing the HF/water stream to a second separator for separation into a modified HF stream containing HF and volatility reducing additive and into an HF/water azeotrope stream containing HF and water; using the modified HF stream as a part of the alkylation catalyst mixture and; removing water from the system by removing the HF/water azeotrope stream from the second separator.
摘要翻译：公开了一种用于从烷基化方法的烷基化催化剂混合物中除去水的体系和/或方法。该方法包括将烷基化反应区流出物送入沉淀器以分离成烃相和催化剂混合物相; 将至少一部分烃相作为含有烷基化物，水，HF和挥发性降低添加剂的沉淀器流出物流送至第一分离器; 从第一分离器去除和冷凝第一塔顶流，从而形成HF /水流; 将HF /水流送至第二分离器，分离成含有HF和挥发性降低添加剂的改性HF流，并进入含有HF和水的HF /水共沸物流; 使用改性的HF流作为烷基化催化剂混合物的一部分; 通过从第二分离器除去HF /水共沸物流，从系统中除去水分。
