摘　　要：目的研究国产消泡剂在天然气净化装置的适用性,解决靖边气田天然气净化装置使用进口聚醚改性有机硅型消泡剂KS-604导致生产运行成本较高的问题。方法从18种国产消泡剂中优选出聚醚型消泡剂A-604,通过对国产聚醚型消泡剂A-604与装置目前使用的进口有机硅型消泡剂KS-604进行室内实验和现场应用试验评价,研究消泡剂A-604在现场装置的使用效果。结果国产消泡剂A-604和进口消泡剂KS-604的性能相当,消泡剂A-604在现场装置中留存时间更长,抑泡能力较强,但其在加量较低时的消泡效果比KS-604略差。将现场装置A-604消泡剂的加注方案调整为2 L/次后,拦液频次平均为每4天1次,最低为每7天1次。结论如果将进口消泡剂KS-604更换为国产消泡剂A-604,在消泡效果接近的前提下,单套天然气净化装置每月可节省费用约1.1万元,全厂每年可节省约132万元。消泡剂A-604可作为进口消泡剂KS-604的替代产品,能大大降低生产运行成本。Objective The aim is to study the applicability of domestic defoamer and to address the problem of high production and operation cost caused by the use of imported polyether-modified silicone defoamer KS-604 in the natural gas purification unit of Jingbian gas field.Method Polyether defoamer A-604 was selected from 18 kinds of domestic defoamers.The application effect of defoamer A-604 in the field unit was studied by an indoor experiment and field application test evaluation of domestic polyether defoamer A-604 and imported silicone defoamer KS-604 currently used in the unit.Result The performance of domestic defoamer A-604 was comparable to that of imported defoamer KS-604.The defoamer A-604 exhibited a prolonged retention time in the field unit and demonstrated robust foaming inhibition capabilities.However,its defoaming effect was marginally inferior to that of KS-604 when the dosage was low.After adjusting the filling scheme for the domestic defoamer A-604 in the field unit to 2 liters each time,the average frequency of liquid interception occurred once every 4 days,with the lowest being once every 7 days.Conclusion If the imported defoamer KS-604 currently used in the unit is replaced by the domestic defoamer A-604,under the premise of similar defoaming effect,a single set of units can save about 11000 yuan per month,and the whole plant can save about 1.32 million yuan per year.The defoamer A-604 can be used as an alternative product of imported defoamer KS-604,which can greatly reduce the production and operation cost.
