Hydrogen Chloride Gas Analyzer: GPro 500

Tunable Diode Laser for HCl Measurement

The GPro 500 hydrogen chloride (HCl) gas analyzer is a unique tunable diode laser spectrometer designed for high performance in challenging applications. It uses a folded-path laser beam design for simple installation and accurate HCl determination.

Top Performance in HCl Measurement
An HCl analyzer for challenging applications, the GPro 500 provides reliable measurement in scrubber towers, flue gas, and VCM applications.

Low Maintenance and Operating Costs
This HCl gas analyzer is designed to operate in situ without a maintenance-prone conditioning system, reducing the total cost of ownership.

Easy Installation
The GPro 500 is an alignment-free TDL gas analyzer, meaning that the typical challenges of TDL installation and alignment are significantly reduced.

Why use a TDL sensor for measuring hydrogen chloride?

TDLs have many advantages over other HCl measurement technologies. Firstly, they are installed in situ in the process pipe or vessel so are exposed directly to the gas and therefore measure immediately. Some other analyzers measure a sample of gas that has been extracted and conditioned, which takes time and increases risk. Secondly, TDLs are immune to the presence of other gases in the process and will only measure HCl. Thirdly, they are extremely reliable and require practically zero maintenance.

 

How can a HCl TDL reduce costs?

Unlike other gas measurement technologies, TDLs have a very low maintenance requirement. Once installed, they will run reliably for many months without needing any maintenance.

 

Are TDL HCl analyzers easy to install?
Sometimes. Once the insertion point has been selected it’s a matter of fitting one or two flanges and a temperature and pressure sensor. Most TDLs are of a cross-stack design, meaning that they’re comprised of two parts (laser source and receiver) that sit opposite each other in the pipe or vessel. The two units have to be very carefully aligned which can be problematic. The GPro 500 has both parts installed in the same unit. The laser source is reflected by a three-sided mirror and is directed back to the receiver. Therefore, no alignment is required. Watch our video on easy installation.

 

In which applications can TDLs be used?

TDLs have a wide range of applications, including process control in direct chlorination and oxy-chlorination; safety monitoring in VCM waste gas recovery; and combustion optimization in package boilers, thermal oxidizers, fired heaters, FCC units, etc. For more information check our Application eBooklet
