MOSCOW (MRC) -- Bharat Petroleum Corporation Ltd (BPCL) has set up a superabsorbent polymer (SAP) technology demonstration plant of 200 tonnes per annum at the Kochi Refinery, according to Kemicalinfo.
The plant was inaugurated by BPCL’s executive director in-charge (refineries) Sanjay Khanna, in the presence of other officials.
Using the in-house acrylic acid as feedstock, SAP technology is used in various hygiene products such as diapers and other incontinence products. The technology was developed by the R&D wing of BPCL for production of hygiene-grade SAP, officials said.
The polymerisation reactor and the drying units were shifted from BPCL’s Corporate Research & Development Centre at Noida. Other units like feed preparation unit, milling, coating and packing units were indigenously engineered and procured by the project team. The project was completed in just seven months.
SAP is a polymer that can absorb and retain extremely large amounts of a liquid relative to its own mass. Therefore, superabsorbent polymer is one of the key components in sanitary napkins, baby diapers, under-pads and adult diapers.
As MRC reported earlier, BPCL said in May, 2021, it can buy up to 2 million tons of crude oil from Iran if sanctions are lifted and terms are attractive.
We remind that in April, 2020, BPCL shipped the first consignment of acrylic acid from its Propylene Derivative Petrochemical (PDP) complex at Kochi Refinery. Acrylic Acid is one of the six niche petrochemical products produced in the new PDP Complex at Kochi Refinery.
Ethylene and propylene are the main feedstocks for the production of polyethylene (PE) and polypropylene (PP), respectively.
According to MRC''s ScanPlast report, Russia's estimated PE consumption totalled 2,265,290 tonnes in the first eleven months of 2021, up by 14% year on year. Shipments of all grades of ethylene polymers increased. At the same time, PP shipments to the Russian market were 1,363,850 tonnes in January-November, 2021, up by 25% year on year. Supply of homopolymer PP and block-copolymers of propylene (PP block copolymers) increased, whereas supply of injection moulding PP random copolymers decreased significantly.
