Ce procede utilise une membrane pour la separation et la recuperation des hydrocarbures melanges a de l'azote. On peut ainsi recuperer l'ethylene et le propylene contenus dans les gaz evacues par la cheminee.

Corporate Source: Membrane Technology/Res. Inc. Source: Petroleum Technology Quarterly 4/4 132-135 (ISSN 1362--363X) (Winter 1999/2000) Language: English ISSN: 1362--363X Journal Name: Petroleum Technology Quarterly Document Type: JOURNAL ARTICLE Publication Date: 990000 Publication Year: 1999/2000 API Bulletin Headings: OTHER SEPARATIONS; PETROLEUM REFINING AND PETROCHEMICALS; POLYMERIZATION, GENERAL; POLYMERS; UNIT OPERATIONS Abstract: A membrane-based process developed by MTR, identified as VaporSep, was successfully applied in polyethylene and polypropylene plants for the separation and recovery of monomers and nitrogen from resin degassing vent streams. Eight propylene recovery units were constructed to separate and recover propylene and nitrogen in polypropylene plants. The systems provided many important benefits. Ninety percent or higher hydrocarbon was recovered depending on the value of the monomers. Nitrogen recovery was optimized, based on its value, and ranged from 65-99%, with purity of 99 vol %. Flaring was completely minimized. The recovery units were supplied as complete skid-mounted packages. Typical payback times were 6-15 mo-range. Four additional units are expected to come onstream in the next few monhts. 2 diagrams, 3 flow diagrams and 3 tables Index Terms: ADDITION POLYMERIZATION; *C2; C2 MONOMER; *C3; C3 MONOMER; CHEMICAL PLANT; COMPOSITION; DEGASSING; ECONOMIC FACTOR; EFFICIENCY; ELEMENT; *ETHYLENE; ETHYLENE HOMOPOLYMER; GROUP VA; HOMOPOLYMER; *HYDROCARBON; INDUSTRIAL PLANT ; INDUSTRIAL PROCESS; MEMBRANE; *MEMBRANE SEPARATION; *MONOOLEFINIC; MONOOLEFINIC MONOMER; NITROGEN; OPERATIONS RESEARCH; OPTIMIZATION; PAYOUT; *PHYSICAL SEPARATION; POLYMERIZATION; PROCESS STREAM; *PROPENE; PROPENE HOMOPOLYMER; PURITY; RECOVERY; *SINGLE STRUCTURE TYPE; SKID MOUNTED UNIT; SYNTHETIC RESIN; *TERMINAL OLEFINIC; TERMINAL OLEFINIC MONOMER; *UNSATURATED CHAIN; UNSATURATED CHAIN MONOMER; VENT CAS Registry Numbers: *115-07-1; *74-85-1; 7727-37-9; 9002-88-4; 9003-07-0 Sets of Linked Terms: 0003 Linked Terms: 9002-88-4; 9003-07-0; C2 MONOMER; C3 MONOMER; ETHYLENE HOMOPOLYMER; HOMOPOLYMER; HYDROCARBON; MONOOLEFINIC MONOMER; PROPENE HOMOPOLYMER; SINGLE STRUCTURE TYPE; SYNTHETIC RESIN; TERMINAL OLEFINIC MONOMER; 7727-37-9; ELEMENT; GROUP VA; NITROGEN 115-07-1; 74-85-1; C2; C3; ETHYLENE; HYDROCARBON; MONOOLEFINIC; PROPENE; SINGLE STRUCTURE TYPE; TERMINAL OLEFINIC; UNSATURATED CHAIN >polyolefin 공장에서 미반응한 모노머를 다시 분리,회수하는 공정에 대하여 알려주세요. 과제를 해야하는데 꼭 알아야 되거든요. 현재 제가 알고 있는 공정은 membrane을 이용한 VoperSep 입니다. 이 외에 또 다른 공정이 있는지...그리고 장,단점 및 그와 관련된 특허와 장비 가격등을 알고 싶습니다. 꼭 부탁드립니다....
