The oil and gas industry continues to be a hotbed of innovation. Activity driven by the need for improved productivity, safety and sustainability, including the reduction of greenhouse gas emissions, with the growing importance of technologies such as scrubbing, wet, semi-wet, and dry flue gas treatment. In the last three years alone, there have been over 534,000 patents filed and granted in the oil & gas industry, according to GlobalData’s report on Environment Sustainability in Oil & Gas: Flue gas treatment.

Flue gas treatment is a key innovation area in environmental sustainability
Flue gas treatment technology essentially involves a post combustion process designed to turn NOx into nitrates or molecular nitrogen.
GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 60+ companies, spanning technology vendors, established oil & gas companies, and up-and-coming start-ups engaged in the development and application of flue gas treatment.
Key players in flue gas treatment – a disruptive innovation in the oil & gas industry
‘Application diversity’ measures the number of different applications identified for each relevant patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of different countries each relevant patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

3M™ Liqui-Cel™ Membrane Contactors developed by 3M is effectively used in the treatment of flue gas. By incorporating 3M™ Liqui-Cel™ Membrane Contactors for Transmembrane Chemisorption (TMCS), the flue gas is emitted from burning biomass. The process of treating flue gas involves two key steps. The flue gas is first "dry" separated to eliminate any remaining particles. Wet separation is used in the second stage to remove excess particles, acids, and salts. Many segments of oil and gas industries such as refineries, FPSOs, and offshore platforms benefit from the membrane gas transfer technology developed by 3M. A few applications include but are not limited to water flooding, removal of CO2 using ion exchange, boiler feedwater deoxygenation, etc.
Another top company for flue gas treatment is Air Liquide with its CryocapTM Oxy technology. Oxy-combustion flue gas serves as the feed for CryocapTM Oxy to capture CO2. The gas is then cooled down and majority of the components such as nitrogen oxides, dust, hydrochloric acid, and sulphur oxides are removed in the pre-treatment unit. The gas is compressed and dried before flowing into the cryogenic purification system. The CO2 is then separated and collected.
Flue gas treatment will continue to become the favoured approach by many oil and gas companies as they continue to seek harmful NOx into nitrates or molecular nitrogen. It helps companies to cut dangerous emissions reduction and mitigate climate change.
