  • Landfill gas caused by the breakdown of organic materials can present a significant hazard as an explosion risk and can be damaging to the environment.
  • Biogas produced from the breakdown of organic matter through anaerobic digestion is typically high in combustible content.
  • Power Generation & Hydrogen Purity maintaining H2 purity will help avoid heat build-up that can cause damage to electric power generators, resulting in dorformity and lost efficiency.
  • Heat-Treating & Metal Finishing production requires monitoring for atmosphere, flue gases and ambient air for safety purposes.
  • Syngas Production using a gasifier as a source of energy will require gas analysis to help determine the energy content
    of the gas before it is burned to optimize the heating value of the gas produced.
  • Steel Making processes, whether BOF or EAF, requires reliable off-gas measuring to optimize chemical energy and post-combustion within the furnace.
  • Oil & Gas (Petrochemical) is a wide ranging industry with many processes and applications such as marine vapor recovery.  Nova’s analyzer solution is a dual-cabinet system with continuous redundant O2 measurement providing greater validity to the sample.

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.

NOVA 800 Series gas analyzer

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.

Tenova Improves EAF operations at Nucor Steel Seattle, Inc.

Tenova Technologies, NextGen®, iEAF® and Water Detection exceed expected benefits in the areas of reduced operating cost, energy consumption and safety.

Mississauga, 18 September 2017 – Nucor Steel Seattle, Inc., has officially signed off on Tenova’s Water Detection System® (WDS).  The System was approved based on controlled testing and successful detection of actual EAF water leaks.

These results confirmed that the WDS met the plant’s requirements to detect and alert plant operators when higher than normal water conditions were present in the EAF.  Furthermore, the WDS has also demonstrated minimal false alarms even in Seattle’s highly variable seasonal weather conditions.

In addition, the NextGen® + i EAF® project previously commissioned in April 2016, surpassed Nucor Steel Seattle, Inc.’s expectation for quantifiable and sustainable improvements in monthly process consumptions and operating costs: average monthly furnace consumptions were significantly decreased in the following areas: 5% electrical, 1.5% oxygen, 11.5% natural gas, 7.5% injected carbon and 32% charge carbon.

Complete system performance has more than doubled from the original estimated savings target determined at the start of the project with total electrical and chemical energy costs per ton of steel being reduced by over 6%.

Tenova’s i DRI® technology achieves demonstrated performance in the areas of yield, productivity, electrical and Power on Time (PON)

Mississauga, 2 August 2017 – Hadeed Saudi Iron & Steel Company has signed a final acceptance certificate for the Tenova’s i DRI® project for the successful delivery of the Furnace Optimization System on DRI fed EAF 5 at Hadeed Plant.

The i DRI® technology project at Hadeed has demonstrated performance in the areas of 1.42% yield increase, 4.1% productivity increase, 3.23% reduction on electrical consumption and 1.6 min reduction on Power on Time (PON).

As applied to the DRI process, the models are responsible to calculate the most important parameters used by the iEAF® control modules. Working alongside the plant PLC, performance of the system was achieved through validation of several fundamental outputs, inclusive of: off-gas measurements using EFSOP® technology; a downstream analyzer; temperature and off-gas flow sensors; furnace and auxiliary service automation; process modeling for real-time mass and energy balance; chemical energy control and optimization of the oxygen lances; and DRI feed rate control.
