Abstract

"remoção de parafina de correntes contendo c4". a presente divulgação se refere a processos para a remoção de parafinas. os processos incluem geralmente fornecer uma corrente contendo c4 que inclui isobutileno, 1-buteno, 2-buteno, n-butano e isobutano, introduzir a corrente contendo c4 em um processo de remoção de parafina para formar uma corrente rica em olefinas, sendo que o processo de remoção de parafina é selecionado dentre destilação extrativa com o uso de um solvente incluindo uma organonitrila, passagem da corrente contendo c4 por uma membrana semipermeável e combinações das mesmas; e recuperar a corrente rica em olefina do processo de remoção de parafina, sendo que a corrente rica em olefina inclui menos que 5% em peso de parafinas.
