Energy-Saving Process Intensification of an Oil Refinery Distillation Plant by an Internal Heat Integration Method
نویسندگان
چکیده
A new approach for energy-saving process intensification was demonstrated by a heat integration method taking for instance the C-5 splitter distillation plant existing for extracting pure c-pentane from a petroleum hydrocarbon mixture obtained by naphtha cracking. A process simulation analysis was made without loosening the specifications of separation of the existing plant. A new process-intensified distillation plant was designed consisting of two heat integrated distillation columns (named HIDiC column 1&2) and a compressor installed between the first HIDiC rectifying and stripping section. It has been found that advantageous process intensification with a great effect of energy-saving can be realized without installing another compressor for the second HIDiC column.
