Product Details
Coal is converted into coke by heating the prepared coal blend
charge in the coke ovens in the absence of air at a temperature of
1000oC-1050oC for a period of 2-15 hours. The volatile matter of
coal liberated during carbonization is collected in gas collecting
mains in the form of raw coke oven gas passing through stand pipes
and direct contact cooling with ammonia liquor spray. The gas
cooled from 800oC to 80oC is drawn to Coal Chemical Plant by
Exhauster. The residual coke is pushed out of the oven by pusher
car through a guide into coke bucket. The red-hot coke is taken to
coke dry cooling plant for cooling.
The main by-product in the process of coke making is crude coke
oven gas and this has a lot of valuable chemicals. Coal Chemical
Plant recovers Ammonia (NH3), Tar and Benzol from CO-Gas. The
primary by-products from Crude CO Gas are Ammonium Sulphate
(NH4)2SO4, Crude Tar, Crude Benzol and cleaned coke oven gas. The
cooled coke from CDCP (Coke Dry Cooling Plant) is separated into 3
fractions, BF Coke i.e. +25-70 mm, which is sent to Blast Furnaces,
Coke Breeze i.e. +0-15 mm, which is sent to Sinter making and nut
coke i.e., +15-25 mm, which is also used in the Blast Furnaces.
