How a 24.5 MW Compressor Motor Guarantees Production in the Petrochemical Industry

The plant at Borealis in Stenungsund (Sweden) operates 24 hours a day, year after year. The process is only stopped every six years for service and maintenance to be carried out. Borealis has now replaced the raw gas compressor motor at the cracker plant in order to boost capacity and ensure continuous operation. A 24.5 MW motor will ensure the operational availability of the petrochemical plant.

The “Quest” Carbon Capture and Storage process: (1) The Hydrogen Unit produces hydrogen for the conversion of bitumen to synthetic crude oil. (2) The CO2 is removed from the “syngas” by contacting it with activated amine. Afterwards the CO2 is separated from the amine. (3) The purified CO2 stream is then compressed by a MAN Diesel & Turbo RG90-8 type compressor in eight stages to a discharge pressure of 130 bar. (4) This is sufficient to send the compressed CO2 about 60 kilometres via an underground pipeline to a wellhead. (5) The dense phase CO2 is injected 2.3 kilometres below the surface into a saline rock formation for permanent storage. (Picture: Shell Canada)

CO2 Capture with Integrally–Geared Centrifugal Compressor

Oil sands have become a major source of unconventional oil: Canada produces around 1.25 million barrels per day from oil sands. Extracting the oil, nevertheless, causes CO2 emissions. Carbon capture and storage (CCS) is a new approach to hamper emissions from bitumen extraction. Compressor specialist MAN took the challenge of providing technology for the Quest CCS Project.

Polyethylene Production

New Sasol Plant to Boost Polyethylene Production

Sasol has inaugurated its new ethylene purification unit, known as the Ethylene Purification Unit 5 (EPU5), in Sasolburg/South Africa. Located at the Sasol Polymers Plant in Sasolburg, the R1.9 billion ethylene purification unit aims to address the growing demand for polyethylene material. According to Sasol, the plant will also ensure better utilisation of the company’s existing downstream polyethylene facilities.
