Top Three Ways Automation can Reduce Raw Material and Fuel Usage

Energy PatriotThe ability to procure sustainable value within a process system, boiler room or plant provides a huge advantage to business. By their very nature, these industries use up fuel and raw materials to create products and energy. The less material you need for any given process, the less you have to pay for. When it comes to the production of consumer goods, such as food products, using less material to create the same result means you can create more product.

The secret to sustainability in the process industry is reliability. Instruments should be calibrated for optimized performance and communicate all valuable information to plant engineers. This is where automation’s abilities thrive. Harnessing automation technology in the following ways will generate reliable and sustainable plant instruments.

  1. Preventative and Predictive Maintenance
    This sustainability issue doubles as a safety issue. The worst kind of safety maintenance a plant can have is reactive. Control systems should be optimized in such a way that plant engineers are made aware of potential errors before they have a chance to wreak havoc. This kind of automation, however, is only preventative. If you want to take your reliability and sustainability a step further, you will calibrate for predictive maintenance as well. An intelligent control system can record and remember the continuous activities of a plant and learn the signs of a potential problem before an error ever occurs. When preventative and predictive maintenance work in tandem, they create an optimized environment with few, if any, major malfunctions.
  2. Alarm Management and Reduction of Nuisance Trips
    Last week, we discussed the importance of alarm prioritization as a method of measurement within the process industry. Alarm management is equally important for sustainability. Every nuisance trip wastes energy and employee time.  At the same time, an overabundance of alarms can confuse plant workers and create misunderstandings of which alarm is the most crucial. Control systems can be automated in such a way that all this is resolved. The system will run smoothly and communicate all information in an actionable manner to the plant engineers. This avoids wasted time, materials and cost.
  3. Instrument Reliability Experts
    All the above will be for naught if the system isn’t put in place with the kind of care instrument reliability experts provide. Make sure you find an engineering consultant with an in-depth knowledge of what reliability and sustainability mean for your business.

The level of sophistication automation can bring to a business’s energy management system is extraordinary. Equally impressive is the money (and energy) saved through implementation of a strategic demand control system. Look no further than Taking Control of Energy Use, an article recently published on InTech filled with examples of savings and energy conservation.

Common practice is for companies to pay a demand charge to utility companies based on peak demand. Enabling a system to moderate loads, reducing peak demand, can save thousands annually. Automation systems go beyond anything that can be achieved manually. Set to act in a specific fashion, intelligent energy management systems can root out inefficiencies, slow down cycling blowers and shut down battery charges as needed.

A key factor of energy management is reducing demand without affecting production. This is where the true brilliance of automation shines. A system can be built to react to countless factors and be programmed in such a way that it never modifies aspects of the business that need to be running at all times.

Envision every asset, tool and machine in a plant working and reacting to one another without the need for manual instruction. The whole system works in harmony, optimized to its best performance level. In order to achieve this improvement, an evaluation of the plant should be performed. This should involve identification of potential savings of the life of a system, saving opportunities and saving initiatives. It can be helpful to have automation experts evaluate your processes for you as they have been trained to notice every detail of a system. Pick the guys who will tell you the truth, not just the truth you want to hear, and you’ll be amazed at the funds you save after you achieve return on investment.

Savings Potential of Variable Speed Drives

Businesses often question the profitability of energy efficient investments and the speed of their return on investment. The fact is, the areas of a business that can most benefit from efficiency investments are unique. This article from Control Engineering Magazine, lists these areas among the many that have the greatest potential of financial and energy savings:

  • Supply voltage optimization
  • Power management solutions
  • Increased factory or process automation
  • Intelligent lighting control and low-energy lighting
  • Building controls
  • Monitoring and targeting systems
  • High efficiency motors
  • Variable speed drives

Variable speed drives, which include variable frequency drives or VFDs, are one of the simplest energy efficient devices a business can invest in. Using customer experiences and conservative predictions, Control Engineering detailed the potential financial savings over 5 years with VSD installation for 10 countries. The United States shows the greatest potential for savings.

VSDs can reduce energy consumption by 70%, with the most receptive applications being pumps, fans and centrifugal compressors. Other assets that can make use of these drives include mixers, centrifuges, reciprocating compressors and extruders.

Keep in mind, the above figure illustrates the savings potential of just one application, variable speed drives. Combined with other advancements in energy efficient technology, savings can rise even higher. There are plenty of energy efficient initiatives for industries to adopt.

New Elements of Life Cycle Cost

New Elements of Life Cycle Cost

BusinessDictionary.com defines Life Cycle Cost as the “sum of all recurring and one-time costs over the full life span… of a good, service, structure or system.” This is a term often used in our industry, where process equipment and boilers are purchased with the intention of running them decades into the future. The rapid pace of technology, along with growing environmental concerns, has added additional elements to the calculation of life cycle cost. For example, a product with a long life may become obsolete before its end. Another concern is environmental laws. While a systems may be compliant with emission laws right now, changes in the future could hold even stricter emission restrictions.

Upgrading typically requires the replacement of a few parts while maintaining a whole system or product. That is changing with technology’s ever increasing advancement. Upgrading can mean different things depending on the product you purchase. If advanced technology is already being sold in the marketplace, other products may become obsolete as the newer technology takes hold. In a few decades, an upgrade may require complete replacement of some equipment. The latest technology tends to have a higher cost, which much be weighed in terms of the product life cycle. More than likely, a plant is better off choosing the latest technology because it will take a significant amount of time before it becomes obsolete. In the end, less money will be spent throughout the life cycle with a product that remains at the forefront of technology for years to come.

Today’s cutting-edge technology, such as intelligent HMI and variable frequency drives, many benefits, which much also be taken into consideration. Greater efficiency, less maintenance and a smaller environmental footprint are all elements of new technology that save money in a system. Such benefits may be necessary in the future. Our culture has only become increasingly concerned about industrial emissions. It can be assumed, then, that the future will see a gradual tightening of restrictions on emissions. A sure way to avoid negative impacts from future emission restrictions is to ensure your plant surpasses current standards. Installing an economizer can be a simple and cost effective way to begin. In addition to reducing emissions, it saves fuel and energy cost by harnessing the energy that would otherwise be lost up the stack. For these reasons, Synergy’s Economizer Solutions provides the fastest return on investment out of all of our products. At the end of the day, any steps in upgrading or optimizing that can reduce emissions can also reduce the cost of running a system. Such ‘green’ elements should weigh heavy in any life cycle cost analysis.

When it comes to calculating the life cycle cost of your next big business purchase, remember to consider more than purchase price, maintenance and life. Additional concerns, such as environmental impact and whether or not the product will be obsolete in the near future should carry a lot of weight in your decision.
