An ethanol dehydration process is provided in which the steam to ethanol ratio is between about 1.0 to 2.0 wt/wt and preferably about 1.5 wt/wt. Steam can be imported from outside the dehydration process such as from an oligomerization or dimerization reaction.

Steam integration in ethanol to jet fuel process

A process for dehydration of ethanol to produce ethylene is provided. Ethanol is dehydrated to produce ethylene and the subsequent conversion of ethylene to longer chain olefins and then their hydrogenation to produce long chain paraffins. In some embodiments, a split feed is employed to improve efficiency and a caustic wash column is eliminated. The advantages of the process include a lower requirement for steam and a reduction in the combined reactor volume of 30-40% when two reactors are used as compared to a single reactor.

Ethanol to ethylene process

A process for oligomerizing an olefin stream comprising charging a light olefin vapor stream comprising ethylene to a first oligomerization reactor containing a first oligomerization catalyst to produce a first oligomerized stream. A heavy olefin liquid stream comprising C3-C8 olefin liquids stream is charged to a second oligomerization reactor containing a second oligomerization catalyst to produce a second oligomerized stream. The two oligomerized streams can be processed to recover fuel streams together.

Process for converting olefins to jet fuel with parallel reactors

A process for oligomerizing and oligomerizing olefins to distillate fuels which regenerates a first stage oligomerization catalyst bed and/or a second oligomerization catalyst bed in situ by contact with an oxygen gas at elevated temperature. The oligomerization catalyst can be restored to full activity. A regeneration process can enable continuous operation.

Process for converting olefins to distillate fuels with regeneration

A process for preparing an olefin stream for oligomerization comprises fractionating an olefin stream to provide a light gas stream and an olefin rich stream. Oxygenates are absorbed from the olefin rich stream into a water wash stream to provide an oxygenate rich water wash stream and a washed olefin stream. The washed olefin stream can then be oligomerized.

Process for preparing an olefin stream for oligomerization with water wash

A process for oligomerizing olefin streams comprising sending olefin streams comprising a C2− olefin vapor stream and a C3+ olefin liquids stream to a first stage oligomerization reactor containing a solid acid oligomerization catalyst to produce a first stage oligomerized stream; oligomerizing said first-stage oligomerization stream in a second stage oligomerization reactor containing a metal catalyst to provide a second stage oligomerized stream.

Multiphase oligomerization process for converting olefins to jet

A process is presented for the production of butadienes. The process includes the separation of oxygenates from the product stream from an oxidative dehydrogenation reactor. The process includes quenching the product stream and solvent and oxygenates from the product stream. The oxygenates are stripped from the solvent with an inert gas to reduce the energy consumption of the process, and the solvent is recycled and reused in the process.

Use of C4 absorber overhead for stripping aldehydes

Processes and apparatuses for the production of butadienes are provided. In an embodiment, a process for production of butadienes includes passing a reactor feed stream comprising a hydrocarbon stream comprising butene, a steam stream and a oxygen rich stream to a dehydrogenation reactor. The reactor feed stream is oxidatively dehydrogenated in the dehydrogenation reactor in presence of an oxidative dehydrogenation catalyst to provide an effluent stream comprising butadiene. The effluent stream is cooled in a quench tower to provide a cooled effluent stream and a bottoms water stream. The cooled effluent stream is passed to an aldehyde scrubber to provide a scrubbed effluent stream and a spent water stream comprising aldehydes. A first portion of the bottoms water stream is passed from the quench tower to the aldehyde scrubber.
