PERBANDINGAN UNJUK KERJA RESIN PENUKAR ION BASA KUAT DOWEX MARATHON A DENGAN PUROLITE PADA PROSES PEMURNIAN BIOGAS SKALA PILOT PLANT
Abstract: Adsorption of carbon
dioxide is a vital process in biogas purification. A previous study has
narrowed down the choice of ion exchange resins for the adsorption process into
two commercial resins, Dowex Marathon A, and Purolite. Dowex Marathon A boasts
the advantage of having no need of any pretreatments to use. Purolite, although
needing pretreatment before usage, costs only roughly a third of Dowex Marathon
A. The objective of the study is to decide on which resin is best suited to
commercially produce biogas free from pollutants, most of which is carbon
dioxide. Both resins at their fresh state were tested for durability by
checking on levels of carbon dioxide content at set time intervals. Results
suggest the Purolite resin to be more durable than the Dowex Marathon A resin.
Data of gas passing through Dowex showed relatively high concentration of CO2
after 10 minutes of operation. While Purolite showed its first signs of CO2
after 20 minutes of operation. Further tests are conducted to compare fresh and
regenerated Pirolite resins. Comparison between fresh and postregeneration
Purolite showed relatively consistent results where the regenerated resin
showed its first signs of CO2 after 25 minutes.
