A PROJECT
Coke Dry Quenching Plant
TCE masterminded the complete project cycle from concept
to commissioning of the Coke Dry Quenching (CDQ) plant
for Coke Oven Batteries 10 & 11 of Tata Steel at Jamshedpur.
The CDQ plant was mandatory to meet environmental
norms to operate the coke oven. The plant is designed with
Best Available Technology (BAT) from globally renowned
suppliers and contractors and is able to reduce coke dust
emission, eliminate the wastage of water as steam in the
wet quenching process and use 80% of the sensible heat
of the circulating cooling gas to generate steam in waste
heat recovery boilers for use in other processes and power
generation.
TCE also carried steam dynamics study for boosting the
power generation capacity by 10MW using additional
steam from existing CDQ plant through PRV based cascade
control with steam from the new boilers, resulting in
considerable value addition to the project viability and
environment. The plant retrofits into the confined space
of the existing plant using various innovative schemes
for enabling works to create working space above and
below ground. The engineering was carried out through
extensive use of smart engineering tools like 3D integrated
approach with a common digital model of the entire plant
by merging the engineering output from various global
suppliers/ contractors to create a seamless product for
safe and time bound execution. Use of 4D construction
simulation helped in meeting the challenges of execution
in deep brownfield conditions by proper sequencing of
activities and support logistics.
