In physical absorption, the most common example is the absorption of water by hydrophilic solids. #input_7_1 { In this process, the bulk material that captures the components is absorbent, and the components that are being captured are absorbates. During operation, monitoring the pressure drop across the column can help to determine the performance of the stripper. Work into the area where the stripper has been applied and take long, overlapping passes. Since the digestate of an anaerobic digestion has both a high temperature and a high TAN content, it is very suitable for ammonia stripping [15]. [20], although their experimental conditions of the stripping process were different from ours, namely the use of digested dairy manure, temperature of 308.15K (35C) and pH of around 10. .btn-red { 3.
