How Mid-South Metallurgical cut Energy Use by 22%

Mid-South in Murfreesboro, Tennessee operates a high-energy plant providing precision heat treatments for high-speed tools – and also metal annealing and straightening services. This was a great business to be in before the energy crisis struck. That was about the same time the 2009 recession arrived. In no time at all the market was down 30%.

Investors had a pile of capital sunk into Mid-South?s three facilities spread across 21,000 square feet (2,000 square meters) of enclosed space. Within them, a number of twenty-five horsepower compressors plus a variety of electric, vacuum and atmospheric furnaces pumped out heat 27/7, 52 weeks a year. After the company called in the U.S. Department of Energy for assistance, several possibilities presented.

Insulate the Barium Chloride Salt Baths

The barium chloride salt baths used in the heat treatment process and operating at 1600?F (870?C) were a natural choice, since they could not be cooled below 1200?F (650?C) when out of use without hardening the barium chloride and clogging up the system. The amount of energy taken to prevent this came down considerably after they covered and insulated them. The recurring annual electricity saving was $53,000.

Manage Electrical Demand & Power

The utility delivers 480 volts of power to the three plants that between them consume between 825- and 875-kilowatt hours depending on the season. Prior to the energy crisis Mid-South Metallurgical regarded this level of consumption as a given. Following on the Department of Energy survey the company replaced the laminar flow burner tips with cyclonic burner ones, and implemented a number of other modifications to enhance thermal efficiency further. The overall natural gas reduction was 20%.

Implement Large Scale Site Lighting Upgrade

The 24/7 nature of the business makes lighting costs a significant factor. Prior to the energy upgrade this came from 44 older-type 400-watt metal halide fixtures. By replacing these with 88 x 8-foot (2.5 meter) fluorescent fittings Mid-South lowered maintenance and operating costs by 52%

The Mid-South Metallurgical Trophy Cabinet

These three improvements cut energy use by 22%, reduced peak electrical demand by 21% and brought total energy costs down 18%. Mid-South continues to monitor energy consumption at each strategic point, as it continues to seek out even greater energy efficiency in conjunction with its people.

Authentication and Access Control

Threats to your data can come from external or internal sources.

  1. There are individuals who don’t have the authorisation but are driven by malicious intentions to gain access to certain information. This may refer to individuals who already belong to your organisation (but don’t have the necessary access rights) as well as those who don’t.
  2. There are individuals who have both the authorisation and, unfortunately, the malicious intentions over certain information.
  3. Finally, there are individuals who have the authorisation, no malicious intentions, but have accidentally exposed the information in question to those without the proper authority.

While curbing threats 2 and 3 would require other methods, threat #1 can be countered if the right authentication and access control systems are in place.

Here’s what we can do for you:

  • Work with your key personnel to determine who gets access to what.
  • Help you decide whether a single factor or a two-factor authentication (2FA) is appropriate for your organisation and recommend which factors are most suitable. Login methods may include but are not limited to the following:
    • biometric devices
    • Kerberos tickets
    • mobile phones
    • passwords
    • PKI certificates
    • proximity cards
    • smart cards
    • tokens
  • Install the necessary infrastructure needed for the factors chosen. For instance, if you opt to use biometrics, then biometric scanners will be installed. We’ll make sure that the authentication terminals are situated in places where achieving optimal traffic and work flow has been taken into consideration.

Benefits of Energy Savings Opportunity Scheme (ESOS)

More than just building energy, improving skills and undertaking audits, Energy Savings Opportunity Scheme works beyond. ESOS adheres to policy coherence, provides information to raise awareness, facilitates energy efficiency market and encourages adoption of appropriate energy efficiency measures.

Generally, ESOS is great for energy professionals and businesses. And in the current situation of UK?s energy industry, this new scheme is a substantial help. The key is to know the benefits that ESOS provides, understand how it can affect you, learn how to maximise its potential and make a big difference. Here?s to explore the highlights of ESOS.

Who benefits from ESOS?

Energy Savings Opportunity Scheme covers non-SME enterprises which includes UK businesses having more than 250 employees; even those with employees fewer than 250 but have annual turnover of more than ?50m and balance sheet exceeding ?43m; or those professionals that belong to a large enterprise. This is in accordance with what Article 8 of the EU Derivative provides.

What are the benefits of ESOS?

ESOS provides opportunities to enhance an organisation’s energy efficiency strategy, of which the benefits include:

Economic Growth and Competitiveness

The implementation of energy efficient measures increases local employment in the labour markets. Consequently, this taps the labour potential and drives economic growth.? In a lower carbon economy, businesses need to develop green projects to maintain economic competitiveness as well. ESOS is strategic approach initiated by the UK government to push technological innovation and energy investments.

Cost Savings and Emission Reductions

ESOS is flexible in such a way that it combines energy policies and innovations tailored to every organisation’s need. The energy efficiency measures taken, resulting from the scheme, quickly cuts down both carbon emissions and energy bills at cheapest possible ways.

Managing Energy Demand

ESOS provides energy security to UK by reducing the energy consumption of enterprises. With this, the economy would be more efficient and less exposed to international energy market volatility. Also, this will lead to more savings from less future investment in energy infrastructure.

Getting your Management Performance Noticed

If you are an energy professional, you will benefit from ESOS by exploiting it ?to boost your charisma towards the company directors. You can show them how the scheme works and how it can save your company substantial costs. Managing energy with ESOS can help an organisation grow. Nevertheless, you are the key person designated to get the project done and achieve success.

How can ESOS make a difference?

More than anything else, ESOS can make a huge change. True to its name, it provides large enterprises the opportunity to manage energy wisely, reduce overhead costs and promote responsible corporate energy consumption.

The International Energy Agency said that investing in energy efficiency leads to growth, additional jobs, competent budgets on public spending and enhanced industry productivity. If you are an energy and environment professional or a non-SME business entity, you hold the impulse to act. Aside from all those excellent business benefits that you get to enjoy, you will be able to contribute a portion towards achieving UK?s national carbon target of 80% in CO2 by 2050.

How Alcoa Canned the Cost of Recycling

Alcoa is one of the world?s largest aluminium smelting and casting multinationals, and involves itself in everything from tin cans, to jet engines to single-forged hulls for combat vehicles. Energy costs represent 26% of the company?s total refining costs, while electricity contributes 27% of primary production outlays. Its Barberton Ohio plant shaved 30% off both energy use and energy cost, after a capital outlay of just $21 million, which for it, is a drop in the bucket.

Aluminium smelting is so expensive that some critics describe the product as ?solid electricity?. In simple terms, the method used is electrolysis whereby current passes through the raw material in order to decompose it into its component chemicals. The cryolite electrolyte heats up to 1,000 degrees C (1,832 degrees F) and converts the aluminium ions into molten metal. This sinks to the bottom of the vat and is collected through a drain. Then they cast it into crude billets plugs, which when cooled can be re-smelted and turned into useful products.

The Alcoa Barberton factory manufactures cast aluminium wheels across approximately 50,000 square feet (4,645 square meters) of plant. It had been sending its scrap to a sister company 800 miles away; who processed it into aluminium billets – before sending them back for Barberton to turn into even more wheels. By building its own recycling plant 60 miles away that was 30% more efficient, the plant halved its energy costs: 50% of this was through process engineering, while the balance came from transportation.

The transport saving followed naturally. The recycling savings came from a state-of-the-art plant that slashed energy costs and reduced greenhouse gas emissions. Interestingly enough, processing recycled aluminium uses just 5% of energy needed to process virgin bauxite ore. Finally, aluminium wheels are 45% lighter than steel, resulting in an energy saving for Alcoa Barberton?s customers too.

The changes helped raise employee awareness of the need to innovate in smaller things too, like scheduling production to increase energy efficiency and making sure to gather every ounce of scrap. The strategic change created 30 new positions and helped secure 350 existing jobs.

The direction that Barberton took in terms of scrap metal recycling was as simple as it was effective. The decision process was equally straightforward. First, measure your energy consumption at each part of the process, then define the alternatives, forecast the benefits, confirm and implement. Of course, you also need to be able to visualise what becomes possible when you break with tradition.
