Maximising the Heat Content of Sales Gas at Kailashtilla Gas Processing Plant

摘要

Natural gas (NG) played an important role in different industrial and commercial sectorsrnin Bangladesh. The natural gas received and transported by the major distributionrncompanies must meet the quality standards on heat-content basis.rnThree gas streams from different sources are combined at Kailashtilla Gas Processingrn(KGP) plant inlet and water content of the gas is reduced to increase heat content in thernprocessing plant. In this work, simulation is carried out in HYSYS simulator based onrnthe design data of the plant and validated the predicted data with the operating data ofrnthe plant. An SQP based optimization framework in HYSYS is developed for thernmaximizing the heat content of the sales gas whereas optimizing raw feed gas flowrnrates, methane composition of sales gas, total energy input of the process and NaturalrnGas Liquefied (NGL) gas temperature.
