Process for separating a highly pure propylene product from a liquefied petroleum gas stream is disclosed, which eliminates a C3 splitter having over 120 trays and the additional equipment that a C3 splitter requires. The process includes passing a feed stream to a dividing wall column to produce an overhead stream, a first side draw stream, a second side draw stream, and a product stream. The first side draw stream is passed to a treatment unit to produce a treated stream. The treated stream is passed to a membrane unit and a permeate stream is passed from the membrane unit to produce a polymer grade propylene stream.

The present disclosure provides processes and systems for dehydrating a byproduct stream in ethanol production. In one embodiment, a feed mixture is distilled with one or more distillation units to remove at least a portion of the water, and form a first byproduct stream. The first byproduct stream is contacted with a molecular sieve unit, thereby forming a product stream. The molecular sieve unit is cyclically contacted with at least a portion of the product stream to regenerate the molecular sieve unit and form one or more regenerate streams. A second byproduct stream including at least one of (1) the regenerate streams and (2) at least a portion of the fusel oil stream is contacted with a separation system, thereby forming a permeate and a retentate. At least a portion of the retentate is forwarded into the product stream.

A system for generating electricity, heat, and desalinated water having a gas turbine system connected to a first electric generator, a waste heat recovery boiler (WHRB) system, a combined heat and power (CHP) generation system connected to a second electric generator, one or more solar powered energy systems, and a desalination system. The desalination system is connected to the CHP generation system and the WHRB system. The gas turbine system generates electricity and heat, the WHRB system is connected to and uses the exhaust of the gas turbine system to provide heat and steam power to the CHP generation system. The CHP generation system produces and provides electricity and heat to the desalination system, which produces product water, and at least one solar powered energy system provides thermal energy to one or more of the gas turbine system, the WHRB system, the CHP generation system, and the desalination system.

The present invention relates to a combined C3/C4 splitter with a membrane system. More specifically, the present invention relates to a combined C3/C4 splitter column to separate highly pure propylene product from a liquefied petroleum gas stream, which eliminates a C3 splitter having over 120 trays and the additional equipment that a C3 splitter requires.

A system and a method for removing gas field chemicals from a feed stream are provided. An exemplary method includes performing a forward osmosis on a feed stream including gas field chemicals to form a concentrated feed stream, and treating the concentrated feed stream in an electrochemical process to form treated water.

Described is a method for concentration and extraction of gas field chemicals. The method includes collecting produced water from a gas oil separation plant, treating the produced water to remove oil, and receiving a feed solution containing a gas field chemical and water. The treated produced water is used as a draw solution to concentrate and absorb water from the feed solution using a forward osmosis chamber. A concentrated feed solution containing the gas field chemical and a diluted draw solution is produced. The concentrated feed solution is extracted and stored for injection into gas wells.

One or more novel processes for producing hydrogen, oxygen, and in some cases, distilled and cleaned water from a contaminated effluent, are disclosed. In one example of utilizing this novel process, the water from contaminated effluent is transferred into a draw solution using an entrochemical system through a vapor-mediated forward osmosis process. The process is enabled by the generation of a wet vacuum in one or more entrochemical cells incorporated into the entrochemical system. This process generates a diluted draw solution that can be utilized as an abundant water feedstock in an electrolyzer for electrolysis, which in turn generates hydrogen and oxygen. In some embodiments, an entrochemical distiller may also be utilized to distill a portion of the contaminated effluent for clean water as a result of thermal transfers during the vapor-mediated forward osmosis process. mediated forward osmosis process.

Provided is a method for separating, from a raw gas containing a specific gas, the specific gas using a gas separation membrane module. The gas separation membrane module includes a housing and a gas separation membrane element enclosed in the housing. The gas separation membrane element includes a gas separation membrane including a hydrophilic resin composition layer for selectively allowing for permeation of the specific gas. The method includes the steps of: increasing pressure in an interior of the gas separation membrane module; increasing a temperature in the interior of the gas separation membrane module; and feeding a raw gas to the interior of the gas separation membrane module in that order.
