The energy efficiency of a coke plant may be increased if natural gas is used in dry quenching of the coke.The heat from the decomposition products of the natural gas is employed to boost steam generation in the waste-heat boiler.In addition, the solid carbon produced in decomposition increases the coke strength.The material and thermal balance of the dry-quenching system is calculated.

The process of dry quenching of coke itself has also received some consideration in the literature , , , but not with the approach and exposition presented in this work.In particular, we recently discovered that a similar analysis was performed by ref.9 published in an italian periodical that, coincidentally, was based on the same cdq.
In dry quenching, insert gas is used to capture the heat.The technology of dry quenching has essentially two components.Capture of sensible heat of coke is gas flowing counter current to coke ii.Use of heated gas to produce superheated steam in a boiler.
Plants, wet quenching of the hot coke presents environmental challenges.Dry quenching and the energy recovery opportunities that the technology presents have been employed in europe and asia as a means of meeting these challenges, although dust control issues must be confronted.
During dry quenching the hot coke is cooled down in a closed cooling chamber by use of an inert gas which is circulated and cooled down thereby within a heat exchanger.The produced steam can be used for electricity production.A scheme of a dry quenching.
