APPARATUS AND PROCESS FOR CONVERTING REFINERY AND PETROLEUM-BASED WASTE TO STANDARD FUELS

摘要

The present invention is an energy efficient method for processing petroleum-based waste including sludge, bottoms or used lubricants, and converting them into useable end products, for example gas and gas/oil fractions. The process produces no wasteful by-products like polluted sewage, heavy asphaltenics and tar by-products. Instead, the process eliminates water through selective absorption by dewatering additives. The dewatering additives are recycled and are reusable themselves. After skimming the dewatered matter, the remainder is processed by thermocatalytic cracking. Some of the active materials used in the cracking reaction are waste products of other processes. The gas and gas oil fractions obtained from this process conform to standard specifications. The process uses equipment that is cost-effective, the great part of equipment is routinely produced. The process and apparatus of the present invention provide a solution for processing refinery and petroleum-based wastes and production of useful and standard liquid fuels.
