Method for reducing GHG emissions
Carbon Capture and Storage (CCS) is an emerging method of reducing greenhouse gas (GHG) emissions of power plants. In a process called ‘scrubbing’, the carbon dioxide emissions can be absorbed into chemical solvents consisting of amines or carbonates. Scrubbing is a well-established method of carbon capture, with virtually every commercial CO2 capture plant in operation using this process.
The CCS Process
In the process, the first step is the removal of impurities from the flue gas, such as hydrocarbons and oxides of both nitrogen and sulfur (NOx and SOx). Next, the purified gas is passed through an absorption column filled with the chemical scrubbing solvent. The solvent reacts with the carbon dioxide and selectively absorbs it from the gas stream. When CO2-rich solvent is heated, the carbon dioxide is released as a nearly pure gas.
Gasmet’s Solution Used in CCS
Our CEMS system can be used to monitor that the CO2 capturing is working properly at the plant. The system is also used to measure other gases because it is vitally important to follow that the capturing process does not impact the emissions of other greenhouse gases. That in mind, the FTIR gas analysis enables plant owners to monitor CO2 levels in addition to almost any other gas from our library of over 5,000 compounds.
