In LNG plants, carbon capture involves removing CO₂ from natural gas during processing to prevent freezing during liquefaction and reduce emissions. The CO₂ is typically separated using chemical solvents, physical solvents, or membranes. After separation, the CO₂ is compressed, transported, and stored in geological formations such as saline aquifers or depleted reservoirs. This process minimizes greenhouse gas emissions, enabling cleaner energy production from liquefied natural gas.
