Vacuum unit for distillation and recovery of fatty acids
In the stage of fatty acid distillation and recovery, it is necessary to draw vacuum from vacuum unit to reduce the boiling point of materials, then heat and evaporate them, then cool them for recovery. How to select vacuum unit correctly in the process of fatty acid distillation and recovery is a topic of great concern. The following is a brief introduction by the manufacturer of water ring vacuum pump on fatty acid distillation and recovery
With the improvement of people’s living standard, the consumption of edible oil has been increasing year by year, resulting in a large number of waste oils and grease residues. Many new technologies and methods have emerged for the treatment and application of these waste oils and grease residues. A whole industrial chain of collection, production and application has been formed in China.
Source of waste grease:
1. Waste oil from restaurants and canteens.
2. The scraps of slaughtering enterprises.
3. Leather processing industry. Source of oil feet: mainly from the leftovers produced by the edible oil processing enterprises, such as cottonseed oil, soybean oil, rapeseed oil, peanut oil and other oil sludge and soap horn.
Processing methods and development prospects: no matter what industry these waste oils and oil feet are used in, they must be purified first to make crude fatty acids. Then according to different oil products, different processing methods are needed to obtain different quality fatty acids, which are respectively used in soap making, paint, fatty acid deep processing, etc. The crude fatty acids are widely used in soap making industry. They can be used for any grease and oil residue. The fatty acids used in soap production mainly go through three steps of acidification, hydrolysis and distillation, and can also be further fractionated into other acids. The production of fatty acids will produce plant asphalt, which can be used in casting adhesives, instead of heavy oil as fuel oil.
In the whole process, the selection of vacuum pump is indispensable for distillation or fractionation. Only heating materials that meet the requirements of certain vacuum degree can make the vacuum pump work best and save energy. The vacuum unit recommended by the vacuum pump manufacturer can help you solve these problems. The vacuum unit can reach a certain vacuum degree in the process of vacuumizing and reduce the boiling point of oil In order to distill or fractionate fatty acids at low temperature, how to choose the right vacuum unit to solve the distillation recovery of fatty acids, EVP vacuum pump manufacturer tells you to develop a perfect vacuum system.
