SMS Digital to Optimize Energy Efficiency at SULB Bahrain
SULB and SMS group’s SMS digital are cooperating in identifying and tapping potentials for energy savings in SULB’s integrated steelworks in Bahrain.
SULB and SMS group’s SMS digital are cooperating in identifying and tapping potentials for energy savings in SULB’s integrated steelworks in Bahrain. Alongside SMS group, Brazil based SMS Group Company energy management and related solutions specialist Vetta and North Carolina USA based world leader in direct reduced iron technology Midrex Technologies Inc are partners to the project. SMS has set up a consulting team made up of its top process and metallurgy specialists from its various plant technology areas, energy experts and specialists in AI based digitalization. Only this unique, concerted approach by all partners involved and their in-depth and highly focused expertise enables a holistic investigation and implementation of solutions that will allow SULB to tap the full scope of energy savings opportunities.
As early as in spring 2020, when the Quick Assessment, Module A of the cooperation agreement, was performed, SULB took a first key step in making its operations more efficient and, as a result, more cost effective. The aims of that first phase of the project were to identify the focus areas and specific measures to reduce the energy consumption, including natural gas, electricity and process gas. Along the complete production chain, fifty measures were identified. A full host of levers were proposed, from the use of smart management systems via adaptation of processes to an improved product mix. For every identified measure, a comprehensive and detailed description, a qualitative assessment of the underlying energy savings potential and the associated implementation effort were provided. An implementation plan was set up, including the milestones on the path to SULB’s strategic energy-efficiency goal.
With Module B, Deep Dive Analysis and Implementation, the second phase of the project has been kicked off. This phase will see SULB and SMS digital draw up a strategy to achieve a fast and significant Return on Investment. Module B concentrates on four areas: direct reduction plant, electric arc furnace and ladle furnace, heavy section mill and integrated energy management. Vetta, for example, will play a key role in the analysis and proposition of an integrated energy management system. The company will evaluate the energy-related key performance indicators (KPIs) of the complete works, derive conclusions and make recommendations as to how energy efficiency can be improved. This analysis will form a key element for the implementation of a digital solution for intelligent energy management. For the direct reduction plant, Midrex will show how the MIDREX H2 technology can help reduce the carbon footprint via the use of green hydrogen, paving the way for a step-wise transition to emission-free steelmaking. Midrex will support SULB via remote-monitoring of the MIDREX plant via the Remote Professional Services option to help make operation of the MIDREX direct reduction plant more energy and cost efficient.
All Module B activities will be performed via real-time data transfer connections by requesting data via remote access. First measures will be completed in early February 2021, while others will be implemented successively until mid-2021. After completion of all project measures, SULB will be able to achieve significant cost savings as a result of lower natural gas and electricity consumption and will be a pioneer in the region with its smart and highly efficient steelworks.
SULB operates an integrated steelworks in Hidd in Bahrain. This steel complex covers the complete production chain from direct reduction to finish rolled products. A key asset of the mill is the flexible combi caster, designed to produce a wide range of cast formats and sizes, ranging from billets to heavy beam blanks. In 2011, SMS supplied the complete equipment for the steelworks on a turnkey basis as a mini mill with an annual capacity of 850,000 tonnes of steel. In 2012, a 1.5 million tonnes per year MIDREX Direct Reduction Plant was added to the complex.
