Abstract
Official abstract text for this publication.
One exemplary embodiment can be a process for cooling a vent stream from a receiver. Generally, the process may include providing a refrigerant including at least one compound contained in the receiver so the refrigerant leaking into the receiver can be compatible with the process.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for cooling a vent stream from a receiver of a depropanizer column in an acid alkylation zone, comprising providing a refrigerant comprising propane to one or more cooling coils contained in a vent condenser of the receiver wherein the propane in the one or more cooling coils is at a pressure greater than the receiver, pumping the refrigerant with a pump and chilling the refrigerant in an exchanger before entering the one or more cooling coils. 2. The process according to claim 1 , wherein the refrigerant in the one or more cooling coils is at a temperature of no more than about −30° C. 3. The process according to claim 1 , wherein the receiver is at a pressure of no more than about 1,720 kPa. 4. The process according to claim 1 , further comprising sending the refrigerant contained in the one or more cooling coils to a pump.
