TRC olefins process

General results about availability of feedstocks for the production of olefins are followed by a description of the Thermal Regenerative Cracking (TRC) process which is used for the processing of heavy fuel ore. This process, which is based on hot solids contracting with hydrocarbon feedstocks to produce olefins, offers advantages over conventional coil cracking. Its principal feature is its insensitivity to coking, which permits cracking of heavy feedstocks, the recycle cracking of unsaturated coproducts, and operation at higher severities and lower steam dilution. It also offers the ability to use low grade fuels. As a result, the process offers a much wider operating flexibility and lower operating costs than allowed by coil cracking. The economic evaluation of the process substantiates these advantages.
