WebBenzene-air mixture is to be scrubbed in a counter current absorption tower using a non volatile hydrocarbon oil as solvent. Inlet gas contains 10% benzene and the entering gas flow rate is 1500 m^3/hr (T=30°C and PT= 1atm). It is proposed to remove 80% of the benzene in the entering gas. Webstripped by counter-current contacting with a steam generated by a reboiler. The lean amine solution from the bottom of the stripper is cooled and fed into the top of the absorber. Fig. 2 shows a schematic diagram of a split-flow amine process [1]. A portion of the lean amine solution is taken from the stripper
