2.2.3 Fume purification system
10720BFor the purpose of fume purification system, two Singaporean SKG-KFC treatment lines are employed, with a fume treatment capacity of 100,000 Nm3/h. The purification process includes semidry-SNCR, spray reactor, activated carbon lime injection, and bag-type dust remover. Activated lime mortar will be sprayed in the spray reaction tower for deacidification; urea solution will be sprayed in the incinerator for denitration; activated carbon sprayed in the flue for detoxification, and the dedusting will be carried out by bag type dust remover. The flying ash and resulting product of reaction will be subjected to solidification process. See Table 12-6 for the amount of pollution in the exhaust after purification as per design.
