Comparison of pressure swing adsorption decarburization with other decarburization methods
Thread Content
What are the advantages and disadvantages of pressure swing adsorption carbon removal compared to other carbon removal methods (such as amine scrubbing, NHD, MDEA, and thermal potassium alkali method)? Is this method the preferred technology for the renovation and construction of small and medium-sized nitrogen fertilizer plants today?
It depends on how the management weighs the factors: pressure swing adsorption requires a high initial investment, but it has low energy consumption later on.
The disadvantages of pressure swing adsorption are high initial investment, large system size, and significant gas loss. Of course, the most appropriate and optimal process depends on the capabilities of the equipment; a decision should be made after weighing the energy consumption.
The carbon dioxide content in the purified gas is generally 0.2% (V); the hydrogen recovery rate is above 99.5% (V), and the nitrogen recovery rate is above 98% (V). There is no power consumption from any mechanical equipment, and the greatest advantage is the absence of electricity usage
