    摘要: A process for removing light components from an ethylene stream may include providing a dried ethylene stream containing ethylene, ethane, CO, CO2, H2, CH4, and C3+ hydrocarbons. The process may include sending the dried ethylene stream to a stripper to produce an overhead stream containing ethylene, CO, H2 and CH4, and a bottom stream containing ethylene, ethane, CO2, and C3+ hydrocarbons. The gaseous phase on top of the stripper may be condensed in a heat exchanger cooled by a refrigerant stream to get a first gaseous phase and a first liquid phase. The first gaseous phase may be condensed in a heat exchanger cooled by liquid ethane or liquid ethylene to get a second gaseous phase containing ethylene CO, H2 and CH4 and a second liquid phase. The first and second liquid phases may be the reflux of the stripper.

    摘要: Disclosed herein is a method and apparatus for recovering hydrocarbons from polyolefin plants. A method of the present disclosure includes introducing a hydrocarbon-containing inert gas from a residual monomer separation unit of a polyolefin plant into a condensation and separation device, condensing hydrocarbons from a hydrogen-containing inert gas in the condensation and separation device, separating the condensed inert gas into a condensed hydrocarbon-containing product and purified inert gas in the device, and sending the condensed hydrocarbon-containing product to a downstream further separation device for removal of dissolved gasses therefrom. A device of the present disclosure includes a condensation and separation device for condensing hydrocarbons from an inert gas and separating condensed hydrocarbon-containing inert gas into a condensed hydrocarbon-containing product and a purified inert gas, and a further separation device connected downstream for purifying the condensed hydrocarbon-containing product originating from the condensation and separation device by separating off dissolved gases.

    摘要: The present invention is a process for the production of styrene monomer from ethylbenzene comprising the steps of: a) catalytically dehydrogenating said ethylbenzene in the presence of steam thereby catalytically producing a dehydrogenation effluent gas containing essentially unreacted ethylbenzene, styrene monomer, hydrogen, steam and divinylbenzene; b) quenching said effluent gas with an aqueous reflux in at least a quenching column to cool said effluent gas, and thereby obtaining a gas at the overhead and in the bottom a liquid stream warmer than the aqueous reflux; c) condensing said overhead gas thereby producing a liquid organic phase, an aqueous phase and a gaseous phase; d) using a portion or the whole of said aqueous phase of step c) as reflux for said step b) of quenching; e) sending to a decanter the liquid stream obtained at step b) to recover an aqueous phase and an organic phase.
