Исследование эффективности применения присадок для обез-воживания дизельных топлив

This document is a master's dissertation focusing on researching the effectiveness of using additives for dehydrating diesel fuels. It covers various aspects related to water contamination in fuels, methods of dehydration, and the application of water-absorbing gels derived from the waste products of the Shurtan Gas Chemical Complex. The dissertation includes experimental results, analysis of different factors affecting the water absorption process, and a proposed technological scheme for water removal from diesel fuels. It also discusses the economic feasibility of the proposed method and reviews existing literature on the subject.
