Houston/USA — This grassroots unit will process about 1.2 million metric tons of vacuum residue feedstock per year and enable Sinochem Hongrun to produce high quality liquid products including clean transportation fuels and chemical feedstocks as well as clean-burning fuel gas. The project is currently in the engineering design phase and targeted for start-up in 2020.

Chris Birdsall, president of Exxon Mobil Catalysts and Licensing LLC, stated that this technology offered greater flexibility than conventional delayed coking, adding that the application of Flexicoking technology would help the Sinochem Hongrun refinery optimize resid upgrading by minimizing capital investment and energy consumption. The process technology eliminates open air coke handling and coal transportation and reduces fired heater emissions due to the clean-burning fuel gas produced by the unit.
