Fuel Gas System

The fuel gas is a combination of several streams from the process. The combined LNG flash gas and heat leak boil-off gas is the main source of fuel gas. The generator fuel is taken at intermediate pressure of the BOG compression system. Vapor from heavy hydrocarbons removed in the liquefaction process are combined with this stream. Finally, for fuel balancing, a small portion of the feed gas is used for fuel makeup. Other than the power generators, the fuel needs are primarily for the gas turbine driving the refrigerant compressor.

燃气系统

燃气是来自处理流程中的多种气流混合体。混合的LNG闪蒸气和热渗漏BOG是燃气的主要构成。发电机燃油在BOG压缩系统里以中压压缩。来自重烃的蒸发气也混合在此气流中，而重烃是经液化工序去除出来的。最终，一小部分原料气被用作燃油补充确保燃油平衡。不同于动力发电机组，主要需要燃油是用作气轮机驱动制冷剂压缩机。
