Expel transforms the operational efficiency of gas analysers. It guarantees the continual removal of 99.999% of liquid water, oil emulsion fluids and solid particulates to 1 micron. What benefits does this result in for gas analysers?

Benefits of Installing Expel for Gas Analysers

Minimises the Risk of Fines and False Readings

Oil consists of hydrocarbons (HCs), and many gas analysers detect HCs. Failing to remove oil emulsion fluids will add more HCs to the sample, invalidating the results. Companies can pay higher than necessary environmental taxes (such as carbon tax) or falsely appear to be breaching environmental laws. Therefore, Expel helps ensure compliance, stopping companies from paying unnecessary fines and facing legal consequences.

Prolongs the Life of Molecular Sieves

Some industries require compressed air to pass through a molecular sieve before reaching the gas analyser. Expel is the ultimate pretreatment to remove the bulk of three primary sources of compressed air contamination. Therefore, the molecular sieve’s adoption capacity can remain optimal for longer.

Petrochemical, pharmaceutical, and natural gas processors commonly require a molecular sieve before compressed air reaches a gas analyser.

Stops Sensor Damage

Liquid water and particulate matter in the compressed air can cause physical damage to a gas analyser. These contaminants will corrode the gas analyser internally and destroy the capillary in the detector. Consequently, the analyser will need replacing.

Stops Calibration Drift

Regular calibration is essential for maintaining accurate measurements taken by gas analysers. Compressed air contamination can compromise the stability of the calibration settings.

Optimises Performance

Contaminants can coat or block the gas analyser’s sensors, reducing sensitivity to the target gases. Therefore, the monitor’s ability to detect subtle changes or low concentrations in gas levels is compromised.

Enhances Safety

In some applications, gas analysers are critical for site safety. They are often used to monitor the levels of toxic gases. Poor compressed air preparation can lead to inadequate safety measures and invalid readings.

Reduces Downtime

Gas analysers are critical for ensuring safety and environmental health. Sites cannot function if emission monitors are inoperable because of compressed air contamination issues. A site can’t function until the gas analyser/s can provide accurate readings. Installing Expel ensures compressed air contaminants do not damage emission monitors, reducing the risk of downtime.

Recommendations and Case Studies

MRU Instruments HIGHLY recommends Expel!

MRU Instruments is renowned for producing an impressive range of gas analyser technology and emission-monitoring products. They serve various industries, including cement, glass, iron, steel, power plants, refineries, breweries, and more.

The President of US Operations, Alex Kinderknecht, wanted to offer the best possible protection for the products they supply.

“The SWG100 Biogas Analyser from MRU Instruments benefits significantly from integrating the Expel 3 unit, designed for advanced moisture control and flood protection. The Expel 3 efficiently removes liquid water, ensuring condensation does not reach the analyser, thus guaranteeing accurate gas measurements and extending the device’s lifespan. Its flood protection feature is also crucial for safeguarding the SWG100 Biogas Analyser against damage, maintaining its operational reliability in demanding environments.”
