Retrofits: A Means for Reducing Energy Consumption in Ammonia Manufacture
Abstract
The manufacture of ammonia is an energy intensive process. Existing large scale plants typically require 33-40 MM BTU (LHV)/ST as energy input. New plant designs can achieve energy levels below 27 MM BTU (LHV)/ST. Therefore, with the cost of energy rising, energy retrofits for existing plants become a necessity.
A theoretical analysis of the energy requirements to produce ammonia is given. Specific areas of the plant are identified as significant energy consumers and recommendations are given for retrofit considerations.
A program for execution of a retrofit is identified. The essential parts are: documentation of existing operations; study of specific retrofit features; establish energy savings; capital cost; down time requirements and schedule; and project implementation.
