Carbon Capture

Improving the carbon footprint of fossil power stations and the chemical industry through carbon capture and storage technologies.

Tackling CO₂ Emissions

Global warming and climate change concerns are intensifying global efforts to reduce the concentration of greenhouse gases such as carbon dioxide (CO₂) in our atmosphere.

Increasingly, attention is focusing on the need to remove CO₂ from the flue gases released by several processes in countless industries including power, cement, chemicals and steel. Carbon capture is a key strategy in meeting today’s CO₂ emission reduction targets.

Choice of Strategy

There are three different carbon capture strategies to choose from, depending on the source of the gas:

Pre-combustion, combining upstream gasification of fuel with precombustion separation of the CO₂
Oxyfuel combustion, combusting the fuel with pure oxygen to create mainly steam and CO₂, which can be easily separated from the flue gas
Post-combustion, where the CO₂ is scrubbed from the flue gas following combustion

Many chemical applications rely on CO₂ scrubbing. Oxyfuel technology is an ideal way to increase the efficiency of combustion processes in new power plants. Post-combustion capture (PCC) is targeted specifically at flue gas in existing power or cement plants. Typically using a solvent to chemically absorb the CO₂ from the flue gases after the combustion process. Or the latest addition to our carbon capture portfolio, HISORP^® CC, where CO₂ is captured from flue gas or other process gases over a wide range of CO₂ feed concentrations.

Putting Captured CO₂ to Good Use

The captured gas can be used commercially – for example as food-grade CO₂, to enhance oil recovery (EOR) or as a feedstock for the production of commodities like methanol or urea. Alternatively, it can be stored underground (sequestered) as a carbon abatement measure.

Downstream Technology

The captured CO₂ can be further purified and liquefied for use in chemical or other industry processes. Alternatively, it can be purified to food-grade level and used in the production of food and beverages.

Complementing our carbon capture offering, we also specialize in CO₂ purification, liquefaction, storage and distribution technologies. We offer a range of prefabricated, standardized solutions to accelerate deployment and maximize cost efficiencies. Supporting the full capacity spectrum, we also design and deliver customized plants.
