Abstract

This work aimed to study the chemical desorption process of CO2 in an aqueous solution of 2-amino-2-methyl-1-propanol (AMP) and piperazine (PZ) carbonated blend. The desorption process was carried out on a wetted wall column with a 0.5 m long film promoter (stainless steel 28 mesh with a known surface area) and 2.2 cm diameter. The process was online monitored by infrared spectroscopy integrated with a PLS model, which allowed the quantification in the liquid phase of free AMP and PZ, PZ mono- and dicarbamate, bicarbonate and total CO2 absorbed in all its chemical forms. The model had a drawback predicting PZ at low concentrations. The desorption was measured at atmospheric pressure (0.93 atm) and at temperatures of 50, 60 and 70 °C and blends of 30/0, 25/5, 20/10 and 0/15 %wt AMP/%wt PZ respectively. A total of 16 experiments were carried out.
