Abstract
Abstract Carbon dioxide (CO 2 ) is removed by absorption in hot potassium carbonate (HPC) solution in ammonia plant. Under actual field conditions, HPC solution can be easily contaminated by system impurities in the circulating solution. These impurities enhance foaming in the CO 2 removal system, which has significant effects in reducing equipment capacity and increasing processing time. In this study, it is assumed that the main cause of foaming is the presence of potassium soap in the HPC solution. The effects on foaming problems of adding calcium oxide have been investigated. The role of a charcoal bed and filtration have also been examined. The results showed that a significant reduction in foam height in an actual field solution can be obtained by using calcium oxide. Values of up to 97% reduction in foam height have been achieved.
