Experimental results of amine emission from the CO2 capture process using 2-amino-2-methyl-1-propanol (AMP) with piperazine (PZ)
Highlights A solvent blend of 2-amino-2-methyl-1-propanol (AMP) and piperazine (PZ) was used for CO2 capture from synthetic flue gas. Emissions of amines and ammonia have been measured by FTIR gas analyser. Ammonia was major degradation product emitted from the absorber. Formic acid has been determined in produced CO2 stream (from the stripper). Water make-up to the absorber top can reduce amine emissions.
Abstract The use of amine scrubbing methods for reducing CO2 emission from burning fossil fuels is growing in popularity. A major challenge of carbon capture methods using amines is high energy consumption. Moreover, the emission of amines from the carbon capture plant gains increasing attention due to environmental concerns. The amines may evaporate from the solution or be released in the form of an aerosol and enter the atmosphere. In order to determine the amines emission, experimental research was conducted using a process development unit. The composition of the gases from the absorber and desorber were measured using a Fourier Transform Infrared (FTIR) gas analyser. A solvent blend of 2-amino-2-methyl-1-propanol (AMP) and piperazine was utilised. Synthetic flue gas containing 12.7–12.9 % vol. (dry basis) of CO2 was directed to the absorber with a flow rate of 100 m3/h. Fresh water was supplied to the top of the absorber to maintain the water balance. No other form of water wash was used. The major components that were emitted together with the treated gas were ammonia and AMP. The produced CO2 contained traces of amine, ammonia and formic acid. The concentration of other degradation products was below the limit of quantification. Increasing the lean solvent temperature by 15 °C resulted in an increase in AMP emission by over 50 ppm. By analysing the vapour pressure literature data with obtained results, the emission was considered mainly as vapour-based. Water dosing at the top of the absorber proved to be effective in reducing amine emissions.
