The first work on modeling a gas-phase polymerization reactor is due to Choi and Ray (1985), which had the objective of understanding the reactor dynamic behavior. [2] One of the first United States fluidized bed reactors used in the petroleum industry was the Catalytic Cracking Unit, created in Baton Rouge, LA in 1942 by the Standard Oil Company of New Jersey (now ExxonMobil). Using this novel fluidised bed, gravimetric measurements and high heating rate, the thermal conversion of biomass was investigated. Measuring task: Level measurement and filter monitoring. In the fluidized bed the product (solids particle) is held in a vertical “gas flow suspension” and thereby ensures optimal process management. The product is removed from the fluidized-bed zone by a system of discharge vases, which operates in cycles determined by the production rate of the reactor. Res.
