  • By offering its PuraMem® VOC membrane separation technology for flare gas recovery, Evonik seeks to reduce CO2 emissions from the energy industry and supports the World Bank’s “Zero Routine Flaring by 2030” initiative.
  • A considerable amount of gas generated in oil production is flared due to economic or technical challenges. The associated gas is often very heavy, rich in hydrocarbons (ie high in C3+) and cannot be used at the wellhead.

German specialty chemicals company Evonik Industries has announced its support for reducing CO2 emissions by turning flare gas into a valuable energy source through membranes.

By offering its PuraMem® VOC membrane separation technology for flare gas recovery, Evonik seeks to reduce CO2 emissions from the energy industry and supports the World Bank’s “Zero Routine Flaring by 2030” initiative.

Oil production generates significant quantities of associated gas which is used, where possible, as a source of energy because oil companies and governments have made substantial investments to capture it. Nevertheless, a considerable amount of gas is flared due to economic or technical challenges. The associated gas is often very heavy, rich in hydrocarbons (ie high in C3+) and cannot be used at the wellhead.

According to the Global Gas Flaring Reduction Partnership, thousands of flares at oil production sites around the world burn about 140 billion cubic meters of natural gas per year, causing more than 300 million tonnes of CO2 to be emitted into the world. ‘atmosphere.

Evonik claims that its PuraMem® VOC membrane separation technology offers a safe and efficient way to process these heavy gases with the lowest operating cost of any technology available. According to the company, the membrane separates heavy hydrocarbons in the form of natural gas liquids (NGLs), water and hydrogen sulfide and generates a clean gas stream that can be used to generate electricity without flaring. . Recovered NGLs can be converted into liquefied petroleum gas (LPG).

“Our innovative membrane technology enables today’s energy industry to increase efficiency and reduce emissions at many unique processing points. The sum of the applications translates into attractive sustainability benefits for the industry,” says Dr. Iordanis Savvopoulos, Fibers, Foams and Membranes Product Line Manager at Evonik.

The World Bank’s “Zero Routine Flaring by 2030” initiative commits governments and oil companies to end routine flaring by 2030. The main objective is to support cooperation between all relevant stakeholders so that solutions to gas flaring can be successfully implemented through appropriate regulation, application of technologies and financial arrangements.
