Abstract

"SEPARAçãO DE BAIXA PRESSãO DE DIMETIL éTER DE UMA CORRENTE DE OLEFINA". é descrito um método de remover dimetil éter de uma corrente contendo etileno e/ou propileno. Dimetil éter é removido em pressão baixa preferivelmente em uma coluna de destilação. A separação de pressão baixa tem o benefício de fornecer uma separação de temperatura relativamente baixa, ao mesmo tempo que considerando a recuperação de uma corrente de etileno e/ou propileno altamente concentrada."LOW PRESSURE SEPARATION OF OLEFIN CURRENT DIMETHYL Aether". A method of removing dimethyl ether from a stream containing ethylene and / or propylene is described. Dimethyl ether is removed at low pressure preferably in a distillation column. Low pressure separation has the benefit of providing relatively low temperature separation while considering the recovery of a highly concentrated ethylene and / or propylene stream.
