Eliminate Delayed Oxygen Measurement Safety Risk in Your Process Gas Analyzer

Having a car alarm that goes off 15 seconds after a break-in puts you at risk of property damage and significant loss. If you wouldn't take this risk with your car, why take it in your process plant?

If you're using an extractive oxygen analyzer that requires sampling and conditioning to prevent explosive conditions, that's exactly what you're getting - an alert up to 60 seconds after an oxygen build up is started. Using an extractive analyzer that requires sampling and conditioning means it's impossible to get real-time information. Measurements are delayed by up to a minute as the sample travels through pipes to the analyzer. In addition oxygen in the sample can be diluted by the gas ahead of and behind it, resulting in a falsely flat excursion curve. An alarm threshold may not be met when it should, so you get one, perhaps inaccurate, result in one minute.

Eliminate the risk. Get continuous real-time measurement. The GPro 500 tunable diode laser gas analyzer from Mettler-Toledo measures in-situ, without the need for sampling and conditioning. It provides continuous measurement and safety-critical applications, so you'll know about oxygen excursions immediately. Don't leave your plant safety up to delayed measurement. Rethink safety. Rethink gas analytics.

No More Purge Gas Required for New Tunable Diode Lasers for Combustion Processes

A new generation of TDLs not only offers exceptional fuel costs savings, but eliminates the need for process side purge gas.

Refineries, petrochemical, fertilizer and power plants worldwide have large numbers of combustion processes in operation, from process heaters and fired heaters to package boilers and large steam turbines. Whenever a process fluid needs to be heated as part of a chemical reaction, or there is a requirement for steam generation, there will be a combustion process at its heart.

This paper presents a review of the general anatomy of a typical combustion process; describing each zone and its function, before discussing some of the challenges of combustion measurement and how modern TDL analyzers such as METTLER TOLEDO’s GPro 500 and its range of process adaptions offer many advantages over typical combustion analysis technologies.

Safety, Quality, Productivity: Rethinking Gas Analytics Across Process Industries

Mettler Toledo Process Analytics designs analyzers and sensors based around a simple concept – how can the design, handling, and maintenance of their products help you improve quality, productivity, and safety? This led to their rethinking gas analytics and the development of a unique portfolio of gas instruments that offers you faster measurements, greater process availability, and unequalled ease of use.

The Mettler Toledo GPro® 500 TDL O2, CO, CO2 and moisture analyzers are designed for ease of installation and low maintenance operation in a wide variety of process applications in the refining, petrochemical, and associated process industries.

The GPro® 500 oxygen gas analyzer is a unique tunable diode laser spectrometer designed for safety applications. It uses a folded-path laser beam design for simple installation and measurement.

GPro® 500 Overview:

• Ideal for applications such as: flare safety control, combustion control, chlorination and oxychlorination, process control, ESP filter production, vent headers, inertization and vapor recovery.
• Is installed in situ, so you get a quick response without the need to extract and condition a sample. This provides a fast response time so that you can make real-time reactions to out-of-spec conditions.
• Is configurable, enabling the oxygen gas analyzer's measurement system to be paired with a variety of process adaptions to meet a wide range of installation requirements.
• Uses Intelligent Sensor Management (ISM®) technology to offer predictive diagnostics on analyzer condition, including informing you when cleaning of the optical path will be required.

METTLER TOLEDO's GPro 500 Series Tunable Diode Laser Gas Sensor

The use of Tunable Diode Laser (TDL) gas sensors is becoming more and more common in industrial processes. This is because they measure directly in the process gas stream without drift or cross-interference and are far more economical to purchase, install and maintain than other gas analyzer types. TDLs use a measurement technology called absorption spectroscopy: they output a beam of laser light at the same frequency that the gas to be measured absorbs light. The TDL analyzes the light after it has passed through the gas stream and calculates the quantity of the target gas in the stream.

Most TDLs are comprised of two parts: the laser source unit and a receiving/analyzing unit. These parts must be installed directly opposite each other, which is not always easy and misaligned can often occur. METTLER TOLEDO's GPro 500 Series solves this by combining both parts in a single unit. A probe attached to the GPro 500 sensor protrudes into the gas stream. A three-sided mirror at the end of the probe directs the beam back through the probe to the receiver, so alignment is always perfect.

The series is available with a wide range of different probes and adaptions that allow the GPro 500 to be placed wherever required in a process. These include: 

• a probe with a filter to prevent dust ingress
• a wafer probe for narrow (2") pipes
• an extractive cell for use with sampling and conditioning systems
• a White cell for trace level detection

Using a modular design, the GPro 500 tunable diode laser gas analyzer allows you to select the process adaption that fits your application, and match it with the parameter that you need to measure. We offer sensors that measure  a variety of gases including Carbon Dioxide (CO₂), Carbon Monoxide (CO), Hydrogen Chloride (HCl), Hydrogen Sulfide (H₂S), Moisture, Ammonia (NH₃), Methane (CH₄) and Oxygen (O₂). 

The GPro 500 does not require maintenance-prone extractive and conditioning systems. This means that you receive consistent performance from your tunable diode laser gas analyzer without the downtime and cost associated with these traditional systems. You achieve reliable uptime, critical in safety applications, at a reduced cost of ownership.
