Questions regarding calculations for high-pressure ammonia scrubber towers

2026-02-09View Original

Thread Content

Problems encountered when calculating the ammonia scrubber: 1. Using RK-SOAVE yields good results for both the gas phase and the liquid phase. 2. Under the same conditions, by adding electrolyte components (H2O/NH3), a chemical formula was obtained; after calculation, it was found that the gas phase could only be purified to a level of slightly over 1000 ppm of NH3, which is 1000 times higher than the level achieved using only the RK-SOAVE method, while the effect in the liquid phase was similar. Gas: 64% H2, the rest are Ar, NH3, N2, CH4, H2O. Operating pressure and temperature: 150 barg/38°C
