Abstract:

Taking the tail gas of 4 Bar absorption system of Hulunbuir 2860 t/aUrea Plant as an example,the characteristics of tail gas and the existing recycling technologies have been comprehensively analyzed,and innovative technical methods for controlling the flammable &.explosive properties of tail gas have been proposed,which have been successfully recycled and applied to engineering practice,providing solutions for the recycling of oxygen-containing tail gas of the same type of large urea plants and for treatment of VOCs in tail gas from urea plants.

Keywords: urea plant / oxygen-containing tail gas / flammability &.explosiveness analysis / recovery process
