摘要: A process and apparatus for the recovery of ethane heavier components from a hydrocarbon feed gas stream. Feed stream is cooled separated into vapor condensed Vapor divided first second streams. First expanded sent to fractionation tower. Second supplied an absorber At least part liquid absorber. Absorber column produces lean Lean subcooled Temperatures pressures streams columns are maintained recover major portion as bottom product, produce at tower overhead, residue
