Project Background:
At Halliburton’s Texas site, Principal R&D Engineer Prashant Shekhar reported frequent moisture issues in the compressed air system. Whilst liquid water is a natural by-product of compressed air, it causes irrevocable damage to pneumatic equipment. Compressed air usage at the site is vast. Multiple temperature changes across the site expose the pneumatic lines to moisture at several points in the system. Because of moisture damage, the engineering team frequently replaced the solenoid, actuated, and positioner valves. The site also wanted to make the protection of gas analysers a main priority, as they are critical to the site’s functionality.
When protecting gas analysers, Halliburton must remove oil emulsion fluids because the oil contains hydrocarbons (HCs). Many gas analysers detect HCs. If oil emulsion fluids are present, more HCs will be added to the sample, invalidating the result. Liquid water is also exceptionally destructive because it will corrode the gas analyser and damage the capillary in the detector. The gas analyser will then need to be replaced, which increases costs, downtime, and wastage.
Summary:
Halliburton must adhere to strict regulations for gas analysers’ air quality standards. Expel helps ensure compliance with these standards.
Compressed air must be treated through a molecular sieve before entering a gas analyser. Halliburton wanted an ultimate pretreatment system to extend the life of the molecular sieve. Expel removes the bulk of liquid water, oil emulsion fluids, and solid particulates before the polishing stage of absorption, chemical removal, and molecular sieve.
Expel is a 3-in-1 solution that removes three primary sources of contamination: liquid water, oil emulsion fluids, and solid particulates. Unlike conventional compressed air filters, the performance of Expel does not drop with use. Rather than containing mesh or sponge-like materials that trap the contaminants, Original AVG has designed Expel using computational fluid dynamics. The internal element circulates liquid water, oil emulsion fluids and solid particulates and deposits them through gravity and airspeed. Because Expel does not retain contaminants, it is guaranteed to maintain 99.999% efficiency, ensuring clean and dry compressed air.
The Results:
- Ensures Compliance: The oil and gas industry has strict regulations regarding air quality standards for gas analysis. By installing Expel, Halliburton has the most efficient filtration method to ensure compliance with these regulations, avoiding fines or penalties.
- Minimises False Readings: Expel ensures the gas analysers receive clean air, providing more accurate readings.
- Reduced Costs: The site made significant cost savings by reducing equipment turnover. For example, using Expel as a pretreatment for gas analysers increased the life of the molecular sieves drastically.
- Superior Equipment Protection: Expel is the ultimate pretreatment to remove the bulk of three primary sources of compressed air contamination. Therefore, the molecular sieve’s adsorption capacity can remain optimal for longer. Clean and dry compressed air also reduces the risk of damage or malfunctioning valves, minimising maintenance and replacement costs.
