Regeneration of oleophilic alumosilicate sorbents: technological process, equipment design

Abstract

The article explores the results of a study on the technology of regeneration of oil and petroleum product sorbents after they have exhausted their resources. A technological scheme of regeneration, optimal temperature modes of the processes and its equipment design have been proposed, allowing cleaning the spent sorbent (based on ex- panded clay, perlite, vermiculite and foam silica) from hydrocarbons and modifying it for reuse in a single processing stage. Deoxidized sorbents preserve its oil capacity characteristics. The advantage of the developed technology for restoring sorbent properties is its simplicity of implementation and economic rationality. The obtained results open up the possibility of wide application of the developed method of regeneration for restoring properties of spent alumosilicate sorbents.
