松南气田集输处理站提高循环水质量研究
|
摘要
分析松南气田集输处理站换热器效率低的原因,主要是循环水质量不达标,杂质在热交换面附着、结垢,同时水管道内壁结垢缩小了管道的实际管径,流量降低造成管道高点和末端换热器供水不足。通过对水样和垢样化验分析,确定结垢成分主要是Ca2+、SO2-4、CO2-3等矿物离子,矿物离子在循环和换热过程中不断浓缩并在换热面过饱和析出,而非结垢成分主要是黏土颗粒和微生物滋生产生的黏泥。补充新鲜水含带泥沙、循环水蒸发使得矿物质浓缩析出、旁滤未正常投用和循环水未加药等四个方面是造成水质不达标的主要原因。为此,通过在水源井出口加装初滤、浓水置换、解决回收水池冻堵问题和加入三防药剂等技改措施,有效提高了循环水质量,为天然气净化工业改善循环水水质提供了技术参考。
This paper analyzed the reason why heat-exchanger in central process factory of Songnan Gasfield is ineffective.It is mainly caused by the unqualified circulating cooling water quality,the impurity attached in heat transfer area.In addition,the scaling in internal wall of water pipeline reduces the real diameter of pipeline and the reduced flow caused inadequate water supply in high point and terminal heat-exchanger.Through analyzing of the water and scaling samples,the component of scaling samples mainly consist of some of mineral ions such as Ca2+,SO2-4,CO2-3 etc.They are precipitated by a concentrated process of circulation and heat transfer in heat transfer area.The components of other materials are mainly clay which is produced by granular clay and microorganism.The leading causes of unqualified circulating cooling water quality are supplementary fresh water with sediment,the minerals precipitated by evaporation of circulating water,the failed bypass filter and circulating water without chemical agent.Following measures have been taken to effectively improve the quality of circulating as installing elementary filter in the outlet of water source well,the substitution of heavy concentrations water,the solution of blockage in recycling tank and the injection of chemical agents,which provides reference for improving circulating water quality in natural gas purification industry.
