Phoenix Equipment has the following state of the art 200,000 TPY polypropylene (pp) plant for sale. The polymerization has two gas phase reactors, so can produce homopolymers, random copolymers and impact copolymers. The extruder is a Coperion ZSK300, with a 5.5MW Loher main motor and associated transformer. The extruder also has a Maag polymer pump, Gottfert on-line rheometer, and electric hot oil systems for the die plate and barrel. A Refinery Grade Propylene (RGP) purification system includes a Propylene Treatment Plant which contains alumina bed driers, a de-ethaniser column, and a de-butaniser column. It supplies treated RGP to a propane-propylene splitter (PPS). The PPS is a heat pump design for minimum utilities demand. Long term supply of catalyst is available. Former plant engineers can provide start-up and training services.

The polypropylene plant has a design capacity of 1280,000 TPY. It contains (4) reaction trains, each of which has capacity of 32,000 TPY. The reaction area consists of four reactor trains. (3) of the (4) trains have two reactors, (1) primary and (1) secondary each. One train has only (1) primary reactor. Propylene, ethylene and other comonomers are fed into the reactor(s). Hydrogen is added to control the molecular weight. The reaction is exothermic. Reactor cooling is achieved by evaporation of liquefied reactor gas, which is injected into the reactor. Flash evaporation of the liquid in the polymer bed ensures the most efficient heat removal. The polymer powder is discharged from the reactor(s) and separated from the gas in a discharge cyclone at atmospheric pressure. Any unreacted monomer separated from the powder is compressed and either recycled or returned to the upstream olefins unit for recovery.
