Abstract

This paper examines the process of treating absorption waste generated during ethylene production at JV LLC “Uz-KorGas Chemical”. Particular attention is paid to the leaching method using alcohols. The conducted studies have shown that the use of alcohols makes it possible to effectively separate the waste into solid and liquid phases.

The solid phase consists of burkeite, a compound that can be used in the production of detergents, thereby creating prospects for its secondary utilization.

The liquid phase mainly comprises a mixture of water and alcohol. A separation method based on distillation is proposed, allowing the alcohol to be regenerated and returned to the technological cycle, thus ensuring solvent circulation. At the same time, purified water is obtained, which reduces wastewater volume and improves the environmental efficiency of the process.

Thus, the proposed technology not only enables the utilization of ethylene production waste but also ensures the recovery of valuable components, contributing to resource conservation and reduced environmental impact.
