Title: Demonstration of Chemical Looping Combustion (CLC) with Petcoke Feed for Refining Industry in a 3 MWth Pilot Plant
Abstract: Chemical Looping Combustion (CLC) is a promising combustion technology with inherent CO2 capture. This process consists in use of metal oxides, called oxygen carriers, to transfer oxygen from Air Reactor into the Fuel Reactor for combustion of Fuels. Accordingly, Air and Fuel are not mixed and the produced flue gas is concentrated in CO2 and not diluted with nitrogen. This inherent CO2 capture results in higher energy and carbon capture efficiencies compared to conventional capture technologies.This paper presents recent achievements of TOTAL in collaboration with IFPEN on CLC development for the refining and chemical industry with petcoke feedstock. A novel concept has been developed with a two-stage combustion reactor, an integrated solid-solid separator (Carbon Stripper), and non-mechanical solid flow control devices. These technologies have been demonstrated at different scales up to a 1 MWth equivalent cold flow prototype and in a 10 kWth continuous pilot plant. These experimental works permitted to carry out a full-scale process simulation with steam and electricity cogeneration. Different sections of CLC are represented in this simulation including reactor system, flue gas treatment, CO2 compression, and steam cycle. In addition, the cost of avoided CO2 has been evaluated for power generation with Chemical Looping technology.Finally, CHEERS project is introduced in which CLC process will be demonstrate in 3 MWth scale via an international collaboration including nine partners from Europe and China.
