CATOFIN dehydrogenation is a continuous process, with cyclic reactor operation. During the hydrocarbon processing step, fresh feed and recycle feed (from C3 splitter bottoms) are vaporized by exchange with various process streams and then raised to reaction temperature in the charge heater. The reactor effluent is routed through a high pressure steam generator, feed-effluent exchanger, […]

Process Description Propylene, ethylene catalyst and any other required co-monomers are fed into the reactor(s). Hydrogen is added to control the molecular weight. Polymerization conditions (temperature, pressure and reactant concentrations) are set by the polymer grade being made. The reaction itself is exothermic and reactor cooling is achieved by flash heat-exchange, where liquefied reactor gas […]
