Tiivistelmä
In absorption-desorption packed columns, if any or certain combinations of liquid or gas flow in combination with the reboiler heat pressure and stripper feed power is too high, the column becomes flooded with the liquid. Flooding is accompanied by a dramatic increase in pressure, resulting in inefficient operation and potential damage to equipment. Three alternative hypotheses were tested to guide this work. To optimize efficiency, however, it is desirable to operate close to flooding as possible. This thesis researched the optimum condition at which the packed column will operate close to 80% flooding.
Four parameters were considered for the operation, this includes the CO2 load; liquid flow; steam heat pressure, and stripper feed power. The Taguchi experimental method was used for the experimental design and analysis for condition ranging from flooding to non-flooding as well as analysis of variance (ANOVA). Also, Katmar software for packed column calculation was used for analysis of pressure drop and flooding.
The analysis obtained an optimum combination of the four parameters under review at 80% approach to flooding. CO2 absorbed was also taken into consideration during this work. The result from this research sets a standard optimized operation for the pilot-scale absorption-desorption packed column of Central Ostrobothnia University of Applied Sciences and application of optimization for improved efficacy of packed columns in various applicable industries. Recommendations are made based on these findings.
