Processing of Heavy Petroleum Residues by Filtration Combustion

Аннотация

A process flow diagram has been developed for two-stage disposal of waste, generated by deep processing of heavy petroleum residues (HPR), using the filtration combustion method to obtain heat as the final product, and optimal processing conditions have been determined. The first stage is the HPR gasification process to produce a combustible aerosol consisting of a low-calorific-value gas with a heat of combustion of about 1.4 MJ/m³ and fine droplets in an amount of up to 80% of the mass of HPR fed and similar to HPR in composition. At the second stage, the aerosol was burned to produce heat. Options for the disposal of the heavy petroleum residues as received and the same with a carbon fuel admixture (up to 5%) have been considered. It has been found that the addition of carbon fuel helps to stabilize the combustion front.
