渤海某终端处理厂天然气脱硫脱碳用消泡剂合成及评价

研制了一种以聚醚改性硅油/硅脂为主剂的天然气脱硫脱碳溶液用消泡剂,测试了其在不同发泡液、温度下的消泡性能。结果表明:贫胺液加入100 mg/L自制消泡剂即可达到应用需求;富胺液需加注超过1 000 mg/L才能满足应用要求。消泡剂加量1 000~1 500 mg/L时,在不同实验温度下可以满足现场应用要求,消泡效果明显优于现场在用有机硅乳液型消泡剂和收集的聚醚型胺液消泡剂。

冀东油田高含水含聚合物采出液处理技术

KYPJ破乳净水一体化处理剂为TA型、AE型、SP型聚醚破乳剂与丙烯酸的反应产物,其中KYPJ-1是针对冀东油田G104-5区块G17站含聚采出液研制的处理剂。室内实验研究结果表明,G17站高含水（85%-90%）含聚（11-14 mg/L）采出液在55℃静置30分钟后分离出的污水,在外加聚合物量为70-100 mg/L和〉250 mg/L两个区间,其含油量很高;按200 mg/L的量加入KYPJ-1后,外加聚合物量在前一区间时,分离出的污水含油量大幅下降;除KYPJ-1外再按20－30 mg/L的量加入絮凝剂,则外加聚合物量在后一区间的采出液分离出的污水含油量降至500 mg/L以下,KYPJ-1的最宜加量为200-250 mg/L。在日处理液量约1.2×10^4m^3的G17站,在含聚14.1 mg/L的采出液中按50 mg/L的量连续加入KYPJ-1,分离出的污水含油量由以前的1600 mg/L降至约300 mg/L,在6个月内维持在500 mg/L以下。

Synthesis of Phenolic Resin Blended Castor Oil Based Modified Polyol for Two Component Polyurethane Coating

Castor oil is used to synthesize phenolic resin modified polyol. Castor oil, phenolic resin were taken in the molar ratio 0.07：0.027 and diethylene glycol （DEG） was also taken in varying hydroxyl numbers to achieve chemical modification in the backbone of synthesized polyol. Physico-chemical properties like acid value, OH value and moisture content of the modified polyol were measured. The prepared phenolic resin blended polyol were reacted with 4, 4-methylene diisocyanate and 2, 4-toluene diisocyanate to formulate the two component polyurethane （PU） coatings. Prepared coating is used to study properties such as gel time, surface dry, tack free and hard surface drying times. It was found that phenolic resin and diethyleneglycol used in synthesizing castor oil based modified polyols show the significant changes in physico-chemical properties of synthesized polyols. The variation in physico-chemical properties of synthesized polyol provide the information for desirable curing of polyurethane systems.
