天然气加气站降本增效的措施
|
摘要
针对某些加气站因运行管理不到位使成本增加、影响加气站效益的问题,在分别对CNG、LNG、L-CNG三种类型加气站的技术特点和经济性简要介绍的基础上,分别阐明了各加气站所采取的降本增效的措施。CNG加气站:选择安全经济的压缩机;完善自控装置,防止泄漏和事故发生;作好加气站校准管理;重视设备巡检。LNG加气站:在卸车、储存、设备管理、工艺设计上最大限度地减少BOG的产生;优选低温设备和管路、优化加注流程和安装BOG回收设备等实际案例表明,降本增效取得明显成效。
Aiming at the problem that the cost increase of some gas refueling stations will affect the benefits of gas refueling stations because of inadequate management, based on the brief introduction of the technical characteristics and economy of three types of gas refueling stations, CNG, LNG and L-CNG, the cost reduction and efficiency improvement measures of CNG and LNG refueling stations are put forward respectively. For CNG refueling stations, the first is to select safe and economical compressors; the second is to improve the automatic control devices to prevent leakage and accidents; the third is to improve the calibration management of refueling stations; and the fourth is to pay attention to equipment inspection. For LNG refueling station, the first is to minimize BOG(boiled off gas) production in unloading, storage, equipment management and process design; the second is to reduce loss by selecting cryogenic equipment and pipelines, optimizing refueling process and installing BOG recovery equipment. Practical cases showed that through the above measures, a remarkable result was achieved in reducing cost and increasing efficiency of gas station.
