Energy balance and technology development

The above analysis puts a pressure to develop a new technology which can capture and reuse the sensible heat in coke. This new technology will also contribute simultaneously to the cleanliness of environment.

Dry quenching technology (DQT) has been developed. The advantages are:

• Elimination of emissions
• Capturing heat and reuse- cogeneration.

DQT has to components

• Capture of heat in gas flowing counter current to coke
• Production of superheated steam in a boiler which can be used for example to run a turbine. Figure 40.1 is the arrangement of various reactors in DQT.
