Solution Challenge

Interconnecting the HP oxygen lines i.e. 31 Bar.

Impractical considering different BOOoperators, Layout and feasibility of suchinterconnections

SS Ring Main of 18-20Bar with controlsystem.

Difficulty in ECR at 5 different oxygen plant, High investment, Shutdown of Plants and safety

Dynamic set-point control philosophy for each ASU independently

Proposal to have variable supply set point in a defined narrow range for PRV operation 18.0-18.6Bar, instead of fixed supply set point for effective utilization of Buffers

Buffer Pressure Set point to PRV

=> 27 Bar High set point

< 27 Bar with a

LD Gas recovery

In contrast to Oxygen Generation and Buffer system, LD Gas will be

generated in batch wise process and ideally it will be supplied consistently by

utilizing Gas holder to consumers.

LD Gas was not fully recovered and fluctuating supply of LD Gas to network

was leading to delays in rolling mills due to limited Gas holder capacity.

OEM had suggested to install GH for Steel making unit-2, it was having

huge capex investment and area requirement.

If GH is commissioned at SMS-2 solving above all, Gas would have flaring

till its commissioning (higher lead time) and SMS-1 would remain handicapped
