AISTech 2017 – Iron & Steel Conference, Another Success for Tenova

Proven Process Control Solutions for the Steel Industry

The City of Nashville, TN was rocked the week of May 8th with approximately 8,000 attendees/exhibitors at the AISTech 2017, The Iron & Steel Technology Conference and Exhibition.

As a supplier of off-gas equipment and technology, Tenova was present at the event as both exhibitor and contributor to the technical program with 10 technical papers for the Electric Arc Furnace and Basic Oxygen Furnace steel making industry combined.  Canadian clean tech company, Tenova Goodfellow Inc. (TGI), with locations in Mississauga and Hamilton, Ontario, contributed a total of four papers.

As the “Center of Excellence” for process control technology development within the Tenova Group of Companies, TGI is focused on delivering innovative and integrated clean tech solutions that will improve the energy efficiency for EAF, BOF steelmakers and cement producers and having already achieved proven dramatic reductions in energy consumption and GHG emissions associated with these industries.

Our starting point is to exercise our innovative thinking cap to incorporate our proven real-time off-gas analysis technologies and fume system capabilities with our rugged off-gas process analyzers, state-of-the-art sensors and advanced modules, produced through our unit company, Nova Analytical Systems.  The end result provides a compelling dual advantage to our customers for hardware and software solutions that results in reduced conversion costs, improved yield and increased productivity.

Our areas of expertise involve several areas:

  1. Endpoint detection for EAF and BOF steel making using a combination of TGI’s off-gas analysis, process models and innovative sensors to improve carbon, temperature and phosphorous endpoint prediction.
  2. Chemical energy control and optimization of EAF burners, lances and injectors using our proven closed-loop control methodology that is fully integrated with the plant automation system.
  3. Automatic tapping control and Intelligent slop detection for BOF steel making to provide operators with greater opportunity to decrease tap time and variability, reducing slag carry-over, as well as mitigate slopping events using lance vibration analysis.
  4. Fume system control for improved energy efficiency, process performance and related equipment design. Using CFD Modeling, our engineering solutions evaluate performance and aid in design specifications with cost effective solutions for all related equipment and processes.
  5. Proven off-gas analysis equipment with multi-point capabilities in a single compact optical analyzer to continuously analyze off-gas from multiple off-gas sampling locations.

Climate Change and Changing Gas Analysis

This past September, the Environmental Protection Agency (EPA) revealed that Volkswagen (VW) had installed software in diesel engine cars sold in the American market to boost their emissions test results. Altogether, roughly 482,000 VW vehicles of various models, as well as Audi A3s — which are manufactured by VW — passed EPA emissions tests using this software.

Smoke and exhaustThe EPA, Environment Canada, the European Environment Agency, and other environmental protection agencies across the globe strictly control the emissions levels that vehicles are allowed to create. They do this for a number of important reasons.

Gasoline and diesel emissions are known to be dangerous to human respiratory health, can damage ecosystems and water sources, and contribute hugely to global warming and global climate change. Investment in renewable energy sources, increased conservation efforts, and purchasing low-emissions cars are all ways in which consumers seek to help counter the effects of harmful emissions and slow the impact of climate change.

The recently concluded Paris Climate Summit has brought the discussion of climate change to the international forefront again. Countries such as Canada are committing to aggressive targets — they’ve joined with a number of island nations to call for a temperature increase capped at 1.5ºC, as opposed to the 2ºC limit goal held by other nations, including the United States.

In order to achieve these ambitious targets, technology will be a key tool in helping consumers and businesses reduce their emission footprint.

Gas Analyzers for Emissions Testing

At Nova Analytical Systems, we understand the importance of reliable and accurate emissions testing. That is why we offer a portable engine exhaust analyzer, the Nova 7460 Series Portable Engine Exhaust Analyzer.

Not all fuel sources are the same, which means that not all exhaust emissions are the same. To ensure that you are testing for the correct substances, Nova 7460 can be customized to test for one or more of the following gases:7460-1gas-largepic

Our portable exhaust analyzer is a highly versatile tool that can be used on both 2 and 4 cycle engines that run on gasoline, diesel, natural gas, or propane. Common vehicles such as cars, trucks, and forklifts can be tested, as can tractors, stationary engines, and more. It comes equipped with a sample probe, internal battery, and 12V DC power cable. Result output options include a receipt printer or a serial output and data software.

You don’t have to be a nation to have a positive effect on global climate change. Keeping your vehicle on a regular maintenance schedule, carpooling, doing all of your errands/deliveries in a single trip, looking into hybrid or electric vehicles and, of course, exhaust gas analyses are all steps you can take today to make a difference.

Variances in Analyzers

Industries such as steelmaking, petrochemical, synthetic and biofuel production, incineration, waste management, and power generation, among others, all have need of gas analyzers. What’s more, each industry has different gas monitoring needs. Even within a single industry, different processes or facilities can require different gas analyses.

Over time, to keep up with the constantly expanding and evolving industrial word, we have developed an expansive line of gas analyzers. Many of them are industry specific, and selecting the correct one for your application can be a daunting task.

Today, we manufacture hundreds of individual gas analyzers.

Analyzer Selection Factors

With such a large volume of different gas analyzers to choose from, it can be difficult to know where to start looking.

Luckily, there are a number of factors that should always be considered when selecting a gas analyzer. Working through these factors can lead you to a small handful of analyzers that could fit your application.

Gas to be Measured

The primary gas that you need to measure should, naturally, be the first factor of your decision. Different gases often require different configurations or sensors in an analyzer — attempting to measure a gas with an analyzer meant for another could lead to catastrophic consequences, making this the most important factor. Some commonly measured gasses, and some industries they’re used in, include:

  • Oxygen (O2) — metalworking, steelmaking, medical, aerospace, water treatment, etc
  • Carbon Monoxide (CO) and Carbon Dioxide (CO2) — industries that burn fossil fuels or use electric arc furnaces
  • Hydrogen (H2) — metalworking, metal heat treating, gasification

Other Materials

It is unlikely that the primarily measured gas is the only thing in the atmosphere where your gas analyzer will be located. What else is in the air? Particulate matter, moisture, and even run of the mill dust can affect the readings a gas analyzer obtains or even, potentially, damage sensors.

If you know that the operating atmosphere is likely to have contaminants of any source, you should skew your search toward Nova gas analyzers with filtering or reading correction capabilities.
