  • Propane removal process
    Patent number: 5152148
    Abstract: In a process for removing propane from a mixed liquid hydrocarbon stream, the depropanizer bottoms from a depropanizer are utilized to reflux the de-ethanizer. The process includes flowing the mixed liquid hydrocarbon stream through a de-ethanizer for separating ethane from the hydrocarbon stream and flowing the de-ethanizer bottoms to a depropanizer for separating the propane. The depropanizer bottoms are used as reflux for the de-ethanizer allowing the overhead temperature to be within range of aerial cooling. Propane recovery of greater than 92% is achievable at these conditions.
