PROCESSO INTEGRADO PARA A SEPARACAO DE UM GAS ASSOCIADO RICO EM DIOXIDO DE CARBONO COMPREENDENDO PRINCIPALMENTE METANO,NITROGENIO,ETANO,DIOXIDO DE CARBONO,SULFETO DE HIDROGENIO E UMA PEQUENA QUANTIDADE DE HIDROCARBONETOS LEVES |
摘要 |
<p>A process for separating a gas-stream rich with both carbon dioxide and compounds heavier than ethane such as the gas from enhanced oil recovery and recovering separate streams of cabon dioxide "sales-gas" consisting of nitrogen, methane and ethane, and a liquid natural-gas-condensate. This process comprises the steps of an extractive distillation which utilizes a hydrocarbon mixture such as naphtha as the solvent and an absorption/desorption step using as the solvent a mixture of dialkyl ethers of polyalkylene glycols.</p> |
