GENERAL METHODOLOGY FOR THE IMPLEMENTATION OF DIVIDING WALL COLUMN TECHNOLOGY IN GAS PROCESSING PLANTS AND CRUDE REFINERIES

Abstract

The present research work tends to study the technical and economical possibility of designing dividing wall column unit, which is characterized by lower energy consumption, less capital cost, high products purity and less construction volume comparing with conventional separation technique, Through development a general methodology for implementation of DWC technology in refinery, gas and petrochemical plants and test the validity of this methodology by implementation in actual cases. This specific research will focus on thoroughly studying all parameters that affected on the DWC design, then compare the conventional separation column with DWC to quantify the potential energy savings and capital cost saving. Complete design of DWC is created on the HYSYS simulation software and calculation sheets, including the operating conditions, energy requirements, unit sizing, products specifications, equipment specification, the capital and operating cost.
