摘要： A method and system for the selective removal of CO2 and/or H2S from a gaseous stream containing one or more acid gases. In particular, a system and method for separating CO2 and/or H2S from a gas mixture containing an acid gas using an absorbent solution and one or more ejector venturi nozzles in flow communication with one or more absorbent contactors. The method involves contacting a gas mixture containing at least one acid gas with the absorbent solution under conditions sufficient to cause absorption of at least a portion of said acid gas. The absorbent contactors operate in co-current flow and are arranged in a counter-current configuration to increase the driving force for mass transfer. Monoliths can be used that operate in a Taylor flow or slug flow regime. The absorbent solution is treated under conditions sufficient to cause desorption of at least a portion of the acid gas.

摘要： The present invention relates to a method for preparing olefin comonomers from ethylene. The comonomer generated can be used in a subsequent process, such as a polyethylene polymerization reactor. The comonomer generated can be transported, optionally without isolation or storage, to a polyethylene polymerization reactor. One method includes the steps of: feeding ethylene and a catalyst in a solvent/diluent to one or more comonomer synthesis reactors; reacting the ethylene and the catalyst under reaction conditions sufficient to produce an effluent comprising a desired comonomer; forming a gas stream comprising unreacted ethylene, and a liquid/bottoms stream comprising the comonomer, optionally by passing the effluent to one or more downstream gas/liquid phase separators; and purifying at least a portion of said liquid/bottoms stream by removing at least one of solid polymer, catalyst, and undesirable olefins therefrom.

摘要： The present invention relates to a method for preparing linear alpha olefin comonomers, such as 1-butene, 1-hexene or 1-octene, from ethylene monomer. The comonomer generated is stored on site for use in a subsequent process, such as a polyethylene polymerization reactor. The method includes the steps of feeding an ethylene monomer, and a catalyst in a solvent to one or more comonomer synthesis reactors; reacting the ethylene monomer and the catalyst in solvent under reaction conditions to produce an effluent stream comprising unreacted ethylene monomer, a catalyst in a solvent, and comonomer; passing the effluent stream to one or more downstream gas/liquid phase separators to form a gas stream of unreacted ethylene monomer, and a liquid stream of comonomer, and catalyst in a solvent; recycling to the one or more comonomer synthesis reactors the unreacted ethylene monomer and a portion of the liquid stream; and storing a remaining portion of said liquid stream for subsequent processing of the comonomer. Some of the benefits of the method include process simplification and reduced capital and operating costs from, inter alia, not having to recover ethylene in high purity nor separate catalyst from comonomer.
