摘要
近几年国内油脂精细化工市场特别是以天然油脂(动物油和植物油)为原料通过水解加工生产脂肪酸、天然甘油以及含氮衍生物系列绿色产品深加工技术不断发展和成熟.为降低生产成本,提高企业竞争力,针对二十世纪九十年代初国内建设的油脂连续非催化高压逆流水解工艺普遍存在的问题,从工艺设备优化、能量回收(低压蒸汽、脱盐水)、提高水解率和本质安全环保等方面提出优化改进方案,为同行业提供参考.
Abstract
In recent years,the domestic oil and fat fine chemical market,especially the deep processing technology for producing green products such as fatty acids,natural glycerol,and nitrogen-containing derivatives through hydrolysis processing using natural oils(animal and vegetable oils)as raw materials,has been continuously developing and maturing.In order to reduce production costs and improve enterprise competitiveness,optimization and improvement plans are proposed from the aspects of process equipment optimization,energy recovery(low-pressure steam,desalinated water),improving hydrolysis rate,and ensuring quality safety and environmental protection,in response to the common problems in the continuous non catalytic high-pressure countercurrent hydrolysis process of oil and fat constructed in China in the early 1990s,providing reference for the same industry.
