Flowsheet Design Of CO2 Adsorption System With Aminated Resin At Natural Gas Reserves

Natural gas is efficient, convenient and relatively clean energy source and its global use
is growing rapidly. It burns to form carbon dioxide (C02) and water (H20) without or
with minimal smoke subject to composition. The presence of carbon dioxide in natural
gas prior to combustionwould lower the heating value of the gas, increase the volume
of gas that must be transported and increase the environmental impact. Most of the
existing acid gas treatment systems in gas plants are limited in C02 removal capacity of
30 mol% to 40 mol%. Hence, this project aims to investigate the potential of an onsite
application of adsorption column with aminated resin to capture C02 at the natural gas
reserves using flowsheet simulation based approach. The simulation of this C02
removal plant that reduces the C02 content down to 30 mol%, i.e. the gas processing
plant's limitation, is done. The effects of temperature, pressure, adsorbent concentration
and its flow rate on performance of C02 removalare investigated using the model.
