摘要

A pilot plant of 2 ton-CO₂/day for CO₂ recovery from flue gas emitted from 250 MW LNG based power plant was tested with aqueous absorbents. The absorbent tested were of different nature such as primary amine (MEA), blend of primary, secondary, tertiary and sterically hindered amine such as MDEA + HMDA, AEPD + DPTA, and TIPA + DPTA. We have studied the CO₂ recovery as function of temperature, concentration, and flow rate of absorbent, pressure and temperature of stripper, and flow rate and temperature of flue gas. It was observed that while CO₂ recovery increases with increase in flow rate and concentration of absorbent, it decreases with increase in temperature and flow rate of flue gas. The CO₂ recovery ratio increases with increase in stripper temperature and decrease in stripper pressure. CO₂ loading (mol CO₂/mol amine) also decreases with increase in stripper temperature.
