C&P Engineering Services Ltd have recently been contracted by Tata Steel for a project which would ‘inject BOS Gas directly into the Blast Furnace Gas (BFG) distribution system’. The aim being to increase the calorific value of the BFG, therefore reducing the volume of Coke Oven Gas (COG) required for enrichment at Morfa Coke Ovens. The COG that is displaced, would be used to directly displace natural gas at the Hot Mill Re-Heat Furnaces.
BOS Gas is produced during the steelmaking process and is collected and used to fuel various combustion processes across the site.
The use of BOS Gas allows for the direct & indirect displacement of imported natural gas resulting in a significant business saving of fuel for Tata Steel as opposed to it being burnt into the atmosphere.
C&P undertook all major electrical activities associated with the £2.3m CapEx project. The scope of work comprised of running cables on a cable tray system from the BOS site to the new control room which was supplied with power, communications and linked to the tata steel network.
As this was deemed to be a hazardous area and a DSEAR zone, this meant that the contractor had to be CompEx trained and competent to install ATEX rated equipment.
In addition, associated instrumentation (including ATEX rated equipment) for the project had to be installed and cabled into junction boxes and cabinet enclosures.
The Scope of work specified the installation of the requisite cabling to each item of instrumentation and valving from the BOS to the BFG control room. C&P also installed new containment systems from the new BOS to BFG control room to two separate locations, one being a new valve train area and the other being a new CV analyser building. New ladder racking was also installed to the new CV analyser location using a mobile elevated working platform, the ladder rack being around 200m in length.
The job fell under Construction Design Management (CDM), and the successful execution of the scheme has resulted in Tata increasing BOS Gas utilisation to reduce both natural gas import and CO2 emissions.
Jordan Bowyer Section Engineering Manager for Fuel & Optimisation at Tata Steel commended C&P Engineering after the completion of the contract.
‘The C&P Engineering team have worked to an extremely high standard to ensure that the electrical installation work carried out was fully compliant to the stated scope of works.
They showed true professionalism by maintaining excellent safety standards throughout installation activities and worked tirelessly under challenging conditions to hit all stipulated execution milestones which allowed the Tata Project Team to deliver this major CapEx scheme safely, to time and budget’
