Guangdong Dapeng LNG cold energy utilization-C2++ extraction process integration

This paper makes a study of some technical and engineering aspects by using C2+ hydrocarbon separation facility at Guangdong Dapeng liquefied natural gas (GDLNG) terminal. In the C2+ hydrocarbon extraction process,the cold energy contained in LNG will be utilized. In order to ensure the optimum operating conditions of the terminal and C2+ hydrocarbon extraction facility by optimizing the current operating processes of the terminal,the C2+ hydrocarbon extraction facility construction plan is proposed. We conducted numerous calculations and simulations using such specific analysis software as PRO II<version 7.0>. Additionally available flow data are used to verify the cyclic send-out rates from the terminal,thus establishing the current and future projected load factors. This study is intended to make sure that GDLNG can continue to supply gas via the pipeline system safely without interruptions and most significantly solves the effects of flow fluctuations at the terminal gasification send-out facility on the hydrocarbons extraction,ensuring optimum pipeline operations and ensuring safe and effective means for such C2+ hydrocarbons extraction process as well. At the same time,the terminal is also in the optimum operation condition. This is very significant to the terminal safety operation and the energy conservation and emission reduction.
