摘要
由于酸水回流泵单台泵运行无法满足工艺运行要求,两台泵运行后无备用机泵、配件储备率和损耗率高,能耗高等问题,参考其他类似装置该泵运行情况,经核算,对陕西延长石油天然气有限责任公司安塞LNG站20万吨/年天然气液化装置酸水回流泵出口进行了改造,出口法兰内径由6 mm扩孔为8 mm,改造后酸水回流泵运行良好,单台泵完全满足工艺使用要求,实现备用机泵,达到了节能降耗,节约了成本。
Since the operation of single acid water reflux pump can t meet the operation requirements of the process,after the operation of the two pumps,there are no problems such as high reserve rate of spare pumps,spare parts,high loss rate,high energy consumption,etc.The outlet of acid water reflux pump in the 200000 t/a natural gas liquefaction unit of Ansai district LNG station of Shaanxi Yanchang Petroleum Natural Gas Co.,Ltd.was reformed,and the inner diameter of the outlet flange was enlarged from 6 mm to 8 mm.The single pump fully met the process requirements,the realization of spare pump,energy saving,consumption reduction and cost saving.
