Petroleum refineries need refractory solutions that provide insulation and abrasion resistance for Fluid Catalytic Cracking Units to improve the efficiency and reliability of producing gasoline and diesel for the demanding transportation fuels industry.
Fluid Catalytic Cracking Units Refractory Solutions
HarbisonWalker International addresses the increasing demand for transportation fuel with advanced refractory solutions that increase production efficiency, improve total performance, and expand unit reliability in the harsh conditions of an oil refinery.
Fluid catalytic cracking is an important step in producing gasoline in the refining process. The process converts thick, long-chain hydrocarbons distilled from crude oil into more profitable, shorter-chain hydrocarbons like gasoline. This is accomplished using catalyst particles. The catalyst and long-chain hydrocarbons are fed into the bottom of the riser line, fluidized, and blown upward at a high velocity, reacting as they rise. The now coke-coated catalyst is separated from the short-chain hydrocarbon gas products by two sets of cyclones in the reactor. The catalyst is fed into the regenerator section, fluidized by an air grid, and the coke is burned off the catalyst particles. The catalyst absorbs this heat, is separated by another two sets of cyclones, and is eventually fed back into the riser. The process repeats in the riser, using the absorbed heat to fuel the cracking reaction.
We provide several products to meet your fluidized catalytic cracking unit refractory lining needs, including our popular GREENLITE®-45-L and HPV® 110 families of products that provide great insulating value in addition to excellent abrasion resistance.
