Polypropylene Unit (PP)
MRPL has Polypropylene Plant located in Mangalore, India.
The unit has been commissioned and started commercial production since June, 2015.
The plant is having annual production capacity of 440 KTPA based on single line and 8000 operating hours.
The Technology Supplier for plant is M/s Novolen, Germany.The line is having two reactors and single extruder. The product is sold under trade name of Mangpol.
Polymer grade propylene produced from PFCC unit is used as feed stock to produce polypropylene product.
The process is based on a stirred gas phase reaction system. The polypropylene line is split into two main processing areas: polymerization and extrusion.
The NOVOLEN polypropylene process can produce many different grades of resin e.g homopolymer, random co- and terpolymer, impact copolymer. Within a product type, the polymer properties are adjusted by the feed rate and type of catalysts, co-catalysts, stereo modifier and hydrogen as well as additives. Hydrogen is used as the chain terminator for controlling the melt flow rate and the molecular weight distribution of some of the product resins. The characteristics of the polymer product are also influenced by the presence of co-monomers.
The resin grades can be categorized as follows:
Homopolymer resins, consisting of propylene only.
Random copolymer resins and impact copolymer resins, containing ethylene as comonomer.
Random terpolymer resins, containing ethylene and butene-1 as co-monomer.
