Gas Processing & CCS
Gas Processing & CCS
Gas Processing and carbon capture storage (CCS) are critical components of the energy industry’s efforts to mitigate greenhouse gas emissions and combat climate change. Gas Processing is a crucial step in the energy industry to purify and separate natural gas into its valuable components. However, this process also generates effluents and by-products that require careful management to mitigate environmental impacts.
Waste Generation
Gas Processing produces various waste by-products, including glycol dehydrator liquids, amine solutions, and hydrocarbon sludges. Proper handling and disposal of these wastes are essential to prevent environmental contamination.
Volatile Organic Compounds (VOCs)
During Gas processing, VOCs are released, contributing to air pollution and smog formation. Implementing effective VOC control measures is necessary to reduce emissions and improve air quality.
Water Contamination
Gas processing involves the use of water for various purposes, leading to the generation of produced water with high salinity and potential chemical contaminants.
Our Approach
At Frischmann Process Technology, we understand the importance of addressing these challenges responsibly and are committed to sustainable practices in gas processing.
We have considerable experience advising the optimal method for treating the toxic by-products from CCS.
Suitable Technologies for Gas Processing & CCS Applications
Wet Air Oxidation and Catalytic Wet Air Oxidation (WAO and CWAO)
This technology is particularly useful in treating organic compounds and hydrocarbons present in the effluent streams. These advanced oxidation processes are designed to oxidise and break down complex organic pollutants into simpler and less harmful compounds.
Activated Sludge Processes
Wastewater is mixed with microorganisms in an aeration tank, promoting the growth of bacteria that consume organic contaminants. The treated water is then separated from the sludge in a settling tank, and cleaned water can be discharged or reused.
Membrane Filtration
The use of semipermeable membranes to separate contaminants from water based on particle size of molecular weight. These processes can remove suspended solids, bacteria, and certain dissolved pollutants, producing treated water of high quality.
Thermal Oxidisers
These are air pollution control devices that combust VOCs in the presence of high temperature and oxygen. The combustion process breaks down VOCs into carbon dioxide and water vapor, significantly reducing harmful emission from gas processing operations.
Adsorption
This involves the attachment of pollutants to the surface of an adsorbent material. Activated carbon is commonly used as the adsorbent, where VOCs and other contaminants are trapped on the activated carbon surface, leading to cleaner air and water as they are removed from the gas stream or effluents.
Electrocoagulation
An electrochemical process that destabilises and coagulates suspended particles and dissolved contaminants in water. It involves the application of an electrical current, causing metal ions to form coagulants that clump together the contaminants. The resulting coagulated particles can then be easily separated from the water.
