Utilization of Waste Fatty Acids Produced by Acid Hydrolysis of Soapstock

Methods of utilization of secondary products obtained in the production of refined vegetable oils are considered. The volumes of by-products formation at fatty acids production at one of the enterprises of Krasnodar region are estimated. The study results of the qualitative composition characteristics of the “lower” and “middle” layers formed by acid hydrolysis of soapstock are presented. The methods of manufacturing from the “lower layer” (acid wastewater) of fertilizers for tomatoes of Gusar variety in the conditions of Krasnodar region, and from the “middle layer” (unoxidized components of soapstock) — a lubricating component of drilling mud are proposed. The possibility of such application of secondary products of refined vegetable oil production was confirmed.
