Process gas chromatograph analyzers – How to choose a PGC?

process gas chromatographs

How to choose the right Process Gas Chromatograph analyzer (PGC) for your application? When selecting a PGC, you may not be sure which make, or model is the best for your process requirements. 

Process gas chromatograph analyzers are durable purpose-built gas analyzing devices which provide specific qualitative and quantitative data, regarding the composition of a gas stream or sample found in an industrial application.

Unlike laboratory-based gas chromatographs, process gas chromatographs are typically configured and used for static applications where the operator requires frequent information about a specific set of target compounds over long periods of time. PGCs are designed to run as stand-alone, easy-to-use, low maintenance gas analyzers.

What is Gas Chromatography (GC) in short?

In short Gas Chromatography (GC) is an analysis technique which is able to separate hundreds of different components while determining the composition qualitatively and quantitively. The principles of gas chromatography make a powerful tool to specifically analyze one or more gases. There are 4 steps to a chromatographic analysis:

  1. Sample collection
  2. Sample injection
  3. Sample separation
  4. Sample detection

A gas sample is collected and then it is introduced into an inert gas stream called a carrier gas. The carrier gas carries the gas sample through a column or series of columns where the gases in the sample are physically separated. Once the gases of interest have been separated by the column, they are directed to a detector which provides an output proportional to their concentration. GC columns are at the heart of the gas chromatograph and responsible for the separation process.

What is the expert take on Process Gas Chromatography (PGC)?

We asked process industry veteran and expert in the field of Process Gas Chromatographs (PGC) Dirk Horst * to do the impossible: To summarize process gas chromatography on two sheets of paper:

What is the role of gas chromatography in process control?

Many people are more or less familiar with analysis of materials as done by special laboratories but do not have a clear idea how the analysis of a big chemical production process is controlled.

For this control, the analysis results from a so called “on-line” analyzer are used and one of the most important types is the process gas chromatograph as manufactured by reputable suppliers.

Gas Chromatography is an analysis technique which is able to separate hundreds of different components while determining the composition qualitatively and quantitively. A PGC is generally applied ranging from the Petrochemical, Refining, Power Generation, Pharmaceutical, Environmental etc.

What are the advantages of a GC application?

  • Requires only very small samples with little preparation
  • Separates complex mixtures into components
  • Results may be rapidly obtained in a few minutes
  • High precision
  • Very Low Detection Limits
  • Only instrument with the sensitivity to detect volatile organic mixtures of very low concentrations,
  • Equipment is not too complex, sophisticated oven with accurate temperature and flow control.

The main reason often mentioned as disadvantage for application of a PGC is because the analysis results are obtained batch-wise and depend on the time it takes for a complete analysis.

However, modern sophisticated analysis techniques and correct selection of the analysis configuration may reduce the analysis time, of heavier hydrocarbon mixtures up to C40, to within a few minutes or faster!

What chromatography analysis techniques are there?

The analysis technique was invented by the Russian botanist Mikhail Tswett in 1900 during his research on the separation of plant pigments. He used a glass column filled with calcium carbonate as adsorbent and petrol ether/ethanol mixtures as transfer solvent to separate chlorophylls and carotenoids.

Nowadays we distinguish several other chromatographic techniques, based on the so called “Mobile Phase”, which is the “Carrier” of the Sample and the type of “Stationary Phase” in the analytical column like the Gas to Liquid Chromatography (GLC).

While Tswett used Liquid to Solid Chromatography, Gas to Liquid Chromatography is mainly applied for on-line Process GC’s.

For the “Mobile Phase” gases like Nitrogen, Helium and Hydrogen are used as a “Carrier Gas” that ‘carries’ a small amount of the process sample mixture through an analytical column.

Process gas chromatograph analyzers thin film onto the inner wall of an Open tubular Capillary column
Process gas chromatograph analyzers have a thin film onto the inner wall of their open tubular capillary column

The analytical column is the heart of the system and contains the “Stationary Phase” which is in case of a GLC an amount of specific liquid that is fixed, by a special technique onto a packing of solid particles (Packed column) OR as a thin film onto the inner wall of an Open tubular / Capillary column, see picture.

The principle used for the separation of a mixture of components in a fluid, that should be a gas or a volatile vapor, is the dynamic concentration distribution of its components between the Mobile and Stationary Phase while travelling through the analytical column.

The injected small volume of sample is ‘carried’ through the column by the mobile phase while separation of the different components is based on the following ‘Retention’ phenomena; combined as “Affinity”:

  • Adsorption – at a surface
  • Absorption – into an immobilized liquid layer
  • Polarity       – electrostatic  interaction between ions   ….. OR by
  • Molecular Sieves – Molecule Size-exclusion chromatography (SEC)

How to use gas chromatography to measure complex sample mixtures?

To obtain high efficient columns for the separation of very complex sample mixtures, the art is to combine the mentioned Retention phenomena and manufacturers have developed thousands of customized columns.

While the time in the Mobile Phase  tm  for each of the components is the same, the time that a component stays in the Stationary Phase may be different, caused by their different affinities, and so may cause different Retention times – tR.  The total time from injection till a component leaves the analytical column is the sum of tm and tR , called the Elution time.

By plotting the signal from the Detector, a Chromatogram is produced showing all the eluted components.

The initial correctly obtained chromatogram is an ultimate tool for later troubleshooting!

Note that the retention is also highly depending on temperature and the linear velocity of the analysis column.

Depending on the type of components to be measured, the main types of detectors used for PGC are the Thermal Conductivity Detector (universal type), the Flame Ionization Detector (organic compounds) and the Flame Photometric Detector (specific for Sulphur and Phosphorus).     

Although the shape of a component peak is normally symmetrical (normal distribution), the shape may be influenced by several parameters like:

Process gas chromatograph analyzers Sharp, symmetrical peaks, meaning a high efficiency and small HETP factor
PGCs can produce sharp, symmetrical peaks, meaning a high efficiency and small HETP factor
  • The time a peak travels through the column
  • The linear velocity
  • The type of Column: Packed; Micro-Packed; Open Tubular; Capillary, Column Efficiency, expressed in the HETP factor of the “Theoretical Plate Model” as developed by Mr. “van Deemter” consisting of several factors influencing the peak width.

The aim of every chromatographer is to achieve nice sharp, symmetrical peaks, meaning a high efficiency and small HETP factor, while the peaks are (preferably) baseline separated (Selectivity) as combined into the Peak Resolution R.

How to identify and quantify peaks in gas chromatography?

Since the Retention times of the injected components are different, their Identification is done using the retention times of the separated components.

The total area of all peaks is in fact representing the total number of molecules of all components that are injected onto the analytical column. Since each component may have a different Area Response, depending on the applied type of detector, a Response Factor is determined for each component by means of a certified Calibration Gas mixture (External Standard). 

When the PGC is running online, this response factor is used for the quantification of the unknown component concentrations of the analyzed process sample.

Range of Process Gas Chromatograph (PGC) applications

Natural gas

Natural gas analysis of the industrial processes designed to purify raw natural gas by removing impurities, contaminants and higher molecular mass hydrocarbons to produce what is known as pipeline quality dry natural gas. Natural gas has to be processed in order to prepare it for final use and ensure that elimination of contaminants.

Custody transfer

Process Gas Chromatographs (PGCs) are used in natural gas custody transfer applications. They provide information on the gas quality and composition with components such as methane, ethane and heavier hydrocarbons, water vapor, carbon dioxide, nitrogen and hydrogen sulfide. These gas chromatographs are normally located on large gas stations with dedicated buyer use.

Total Sulfur, H2S and COS

Hydrogen sulfide (H2S) and other sulfur compounds exist naturally in natural gas fields. It is necessary to remove these sulfur compounds from the gas in order to preserve public safety, reduce corrosion in pipelines, meet contractual agreements and to control odor in the gas. Thus, the analysis of hydrogen sulfide and total sulfur in natural gas by PGCs is critical to the natural gas industry.

Flare gas monitoring

Gas flaring is a source of emission that pollute the environment. Flaring releases greenhouse gases into the environment and further contributes to the problem of climate change. Hence, national and local government bodies are increasingly requiring process plants to monitor, report, and reduce emissions from their stacks and flares.

ASTM D3710 gasoline

Standard method for boiling range distribution of gasoline and gasoline fractions by process gas chromatography. This test method covers the determination of the boiling range distribution of gasoline and gasoline components. This test method is applicable to petroleum products and fractions with a final boiling point of 500°F (260°C) or lower as measured by this test method.

ASTM D2887 diesel

Standard method for boiling range distribution of petroleum fractions by process gas chromatography. Standard method for boiling range distribution of gasoline and gasoline fractions by process gas chromatography. This test method covers the determination of the boiling range distribution of petroleum products. The test method is applicable to petroleum products and fractions having a final boiling point of 538 °C (1000 °F) or lower at atmospheric pressure as measured by this test method.

Catalytic reforming & refinery hydrotreating

Catalytic reforming is a major conversion process in petroleum refinery and petrochemical industries. The process converts low octane naphtha into higher octane reformate products for gasoline blending and aromatic rich reformate for aromatic production. Hydrotreating is an important step to remove unwanted sulfur from streams that are used as feeds to some refinery units.

Specialty & industrial gasses

The field of analytical application is extremely diverse. Whether they are used to monitor the quality of foodstuffs, test engines in the automotive industry, control processes in the chemical or pharmaceutical industries, or in medicine, metallurgy or environmental monitoring: analytical methods ensure process control, quality assurance and even compliance with statutory regulations everywhere.

Process gas chromatograph analyzer monitoring with AIM predictive maintenance

ASaP AIM predictive maintenance software rugged tablet
With AIM on your mobile device, you can make well informed decisions at the office, in the field, in a hazardous area, or even from your comfy chair at home

Maintenance departments use different software packages for maintenance activities, due to different types of gas analyzers in analyzer houses or shelters. 

How is AIM applied?

On a plant or in an analyzer shelter, different types of gas analyzers and sample systems are in operation. Because the analyzer performance is also depending on the performance of the sampling systems, these parameters will also be acquired. There is a need for analyzer shelter performance monitoring and prediction of fouling of the sample system to prevent breakdown of the analyzers. Improvement of sample conditioning maintenance is necessary to increase uptime of the analyzers.

The result of PGC analyzer monitoring with AIM

By monitoring the external factors like temperature, flow rate and condition of the sample system, the uptime of the analyzer increased significantly. Using preventive scheduled maintenance, unexpected issues are reduced, which leads to less ad hoc maintenance. By monitoring the sample system and analyzer as one item, the frequency of interventions by maintenance personnel is reduced.

What is AIM predictive maintenance software?

AIM is easy to use predictive maintenance software and an analyzer data collection for operators and reliability engineers similar to AMADAS to get insight into their measurement and analyzer equipment.
