Abstract

Typically, for a high volume, low condensate-gas ratio offshore gas production field having high content of carbon dioxide (CO2), hydrogen sulphide (H2S), mercury and solid particulates having to meet Liquified Natural Gas (LNG) inlet specification would require an enormous facility exceeding the largest available floatover vessel capacity. Aside from an enormous and complex processing facility, it would also require a large emergency disposal system and sour service pipeline material to cater for start-up and process excursion scenarios. In order to obtain a commercially attractive solution while meeting technical integrity and designing for operational excellence in mind, several innovative design approaches were implemented. The scope of this paper will cover major optimization implemented at gas treatment system, emergency blowdown system, export gas pipeline, and venting system at receiving platform.
油气风化的不确定性:高污染气田的挑战与设计优化
通常,对于体积大、凝析气比低的海上油气田,由于二氧化碳(CO2)、硫化氢(H2S)、汞和固体颗粒含量高,必须满足液化天然气(LNG)进口规范,这将需要一个超过最大可用浮式船容量的巨大设施。除了庞大而复杂的处理设施外,还需要一个大型应急处置系统和酸液服务管道材料,以满足启动和过程偏移的需求。为了获得商业上有吸引力的解决方案,同时满足技术完整性和卓越运营的设计,实施了几种创新的设计方法。本文主要对燃气处理系统、应急排污系统、输气管道、接收平台排气系统进行优化。
