Degassing

Using chemical degassing products will help you gain a competitive edge, increase profitability, and reduce turnaround time for your operation.

Superior Degassing and Decontamination with FQE® LEL-V

The demand for system decontamination, including degassing, which meets or exceeds regulatory safety and environmental requirements is growing. FQE LEL-V is a safe, non-hazardous, non-petroleum based product for use in vessel decontamination and degassing.

It is a proprietary blend of surfactants, penetrating and wetting agents, and specially selected safe chemicals that are not SARA 313, DOT, California Proposition 65 or CERCLA reportable. FQE LEL-V is best described as a super-detergent.

The competitive edge in degassing, cleaning, and turnarounds

A carefully planned turnaround utilizing FQE LEL-V degassing and absorption process returns processing and crude units to full production in record time.

  • yellow-bulletCan be merged into the shutdown phase – minimizing turnaround time
    yellow-bulletGreatly reduces steam-out time
    yellow-bulletLimits release of hydrocarbon gas
    yellow-bulletExpedites entry into vessels without the use of fresh air
    yellow-bulletReduces mechanical cleaning time
    yellow-bulletWastewater disposal without concern for bioculture toxicity

Degassing is environmentally safe and friendly

Degassing reduces personnel safety concerns and reduces the release of gas into the environment.

Get Superior Performance at a More Economical Price with FQE LEL-V Eco

FQE LEL-V Eco - degassing product

FQE LEL-V Eco is designed to compete with less expensive competitor products. While less expensive than FQE LEL-V, FQE LEL-V Eco provides very good hard surface cleaning – much better than the competitive products that were tested. FQE LEL-V Eco also showed very good LEL reduction compared to the competitors.

FQE LEL-V Eco is water-based, non-combustible, mildly alkaline (pH 8.5-9) and safe for waste water treatment plant disposal. The degreasing capability for FQE LEL-V Eco is derived from new technology in solvency wherein the ingredients have very high KB Factors (well over 100+), but also act as surfactants. In addition, stripping of hydrocarbon vapors is accomplished by absorbency.

All of the FQE LEL products are chemically compatible with FQE H2S Scavenger and FQE Pyrophoric and can be added in conjunction with these products during the steaming process for rapid reduction of LEL readings, effective control of both Hydrogen Sulphide and Iron Sulphide deposits.

Wastewater Disposal

FQE LEL-V will not strongly emulsify residual oils, allowing for a rapid phase separation of the oils after the circulation fluid has been removed from the unit. The residual oils can be recovered or disposed of. The remaining wastewater will be relatively free of oils and can be sent directly to the wastewater plant for processing. No prolonged delays in wastewater processing are expected.
