Abstract: (151 Views) |
An isomerization process by limit the amount of benzene, aromatic, and olefin in gasoline, cause to increase the octane number and decrease the environmental issues. In this research, has been investigated the modification of the isomerization process in order to optimize the energy consumption at Persian Gulf Star Oil Company by pinch technology. According to the pinch analyses, to optimize the energy consumption one retrofitting case was investigated on the heat exchanger in regeneration of feed and makeup gas drier that had the highest amount of cross pinch. As a result, a new heat exchanger was used to optimize energy consumption, that the cross pinch was reduced by 19.3% and the utility consumption was reduced by 3.61%. The new exchaner, by eliminating medium pressure steam in the unit, saved $210,955 per year with a 7-month return on investment. This proposal is very efficient and useful because of its economic efficiency.
