摘要: Condensate from a urea crystallizer is directed to low pressure boiler or heat exchanger and evaporated accomplish thermal decomposition of any biuret contained therein into ammonia carbon dioxide which are subsequently removed recycled the plant, if desired, leaving substantially free water sufficient quality satisfy environmental regulations guidelines for use as feed water.
