Abstract:

The working principle, classification and characteristics of lithium bromide refrigeration units are briefly introduced, the application situation of phase Ⅰ and phase Ⅱ lithium bromide refrigeration units in synthetic ammonia production plants is described. After 2 sets of lithium bromide refrigeration unit are put into operation, low grade heat energy of the decarbonization lean liquid and residual heat of low-temperature converted gas are successfully recovered. The obtained cold water is used in the ammonia plants, and the production of ammonia unit is increased by 20 t/d, and it can generate income of 6.48 million yuan annually.
