the syngas purification process first ashes and inorganic particles are removed in cyclones and water scrubbers then the syngas is further cooled to a temperature suitable for a hydrolysis reaction generating sour gas i e a form of syngas containing h 2 s co 2 and ammonia after the ammonia is removed in a water scrubber and the h 2 s and co 2 are removed in an mdea contactor connected to an mdea regenerator the cleaned syngas is saturated with steam and send through a final filter before entering the gas combustor 44 the mdea solution rich in h 2 s and co 2 is heated in the mdea regenerator to generate fresh mdea and release a stream of acidic gas primarily comprising h 2 s co 2 and water vapor in a sulfur recovery unit the h 2 s is converted to elemental sulfur for disposal heat exchangers may be included to recover sensible heat from numerous heat sources present in the syngas purification process the syngas clean up unit 32 includes a cyclone 101 the first water scrubber 104 the syngas cross heat exchanger 110 a cos hydrolysis unit 122 the second water scrubber 126 a sour water accumulator 134 an meda contactor 142 a syngas saturator 184 the saturator heater 186 and a final filter 192 for generating clean syngas 33 it also includes a rich mdea surge drum 148 an mdea cross heat exchanger 152 an mdea regenerator 158 an mdea reboiler 160 an mdea circulation pump 164 a condensate accumulator 170 and a sulfur recovery unit 174 for recovery of sulfur 177 in addition the syngas clean up unit 32 includes a network of.
