Development of the design of a mobile unit for processing petrochemical waste into liquid fuel is a continuation of the work on the development of a pilot plant with a capacity of 5000 tons/year for processing acid resins into liquid fuel and coke. According to the results of research of thin-layer cracking process of petrochemical wastes on the test bench of NNGU the technological scheme and layout of the mobile unit were developed. In accordance with the types of petrochemical wastes the units of different capacity and purpose were proposed.
