Nova Analytical Systems (Tenova) commissions six (6) DuraNOVA Continuous Gas Analyzers for Ametek Reading Alloys Milling Plant

Mississauga (ON), November 16, 2017: In June 2017, Nova Analytical Systems, a Unit of Tenova Goodfellow Inc., received an order from Ametek Reading Alloys, a division of Ametek Specialty Metal Products, for six (6) DuraNOVA Continuous Process Oxygen Gas Analyzers. Ametek Reading Alloys is a global leader in the production of specialty powdered metals, particularly those with a titanium base. In October 2017, these six units were commissioned by NOVA field service engineers.

Titanium powder has an affinity for oxygen (O2), which creates a potential fire hazard during the powder milling operation process.  Historically, to remove the possibility of a hazard developing, an Argon blanket was introduced to provide an inert environment for this industrial application. The inert blanket of gas prevents the powder being processed from reacting with oxygen from surrounding air and sparks created by the mill. For Ametek’s powdered metals process, adding Argon to this process greatly reduced the risk of fire, however, there was still two unknowns; was the drum installed properly and was the oxygen sufficiently purged?

The objective for Ametek using DuraNOVA continuous offgas analysis was twofold: first, validation that the milled powder drum was installed and sealed properly and second, that the system was sufficiently purged of oxygen to allow the milling process to start. There was a need to continuously measure for the presence of O2 in the inert environment created by the Argon. To accomplish this, a DuraNOVA Model 810N4analyzer was installed on each of the six milling cells in the plant.  The analyzer O2 control alarm was connected to an interlock that controlled the mill and vibrating table. In this way, the cell cannot be energized until the measured O2 level in the Argon atmosphere is below the analyzer alarm setting.

The DuraNOVA continuous gas analyzer was selected for its simplicity to use, flexibility and overall ruggedness to accurately measure low oxygen concentrations in a very high dust load environment. DuraNOVA Model 810N4 meets the Class 2, Division 1, Group E area rating required for manufacturing that involves powdered metal processes. The equipment is also equipped with automatic calibration and purging functions, which will keep the equipment in a ready-state despite the batch-nature of the process.

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.
