Case Study — Mass and Energy Balances

There are several important observations from the series of mass and energy balances presented in this section. At 280 tonne per day capacity, the process is able to produce about 5800 kg of medium-pressure superheated steam (380°C and 4000 kPa) every hour. About 60% of this steam is available for export. This contributes a valuable source of operating revenue to the plant. 

The plant is found to be highly efficient with a reaction yield of approximately 95%. Effluent levels from the process are small. There are no liquid waste streams and the tail gas should contain less than 1000 ppm of nitrogen oxides.
