Vessel Degassing for Turnarounds, Pressure Vessels, Bullets, and Exchangers.

Process vessels are the critical path on a turnaround, and the degassing wait before entry is where days go. Hasten Cleanse is a water-based concentrate that circulates or sprays into the vessel, bonds to the hydrocarbon film, suppresses the vapor it generates, and lifts the film for removal. Nothing flammable goes in, and the wash water goes to the plant as non-hazardous.

Vessels, bullets, exchangers. Hydrocarbon film on steel in a confined space. Circulate, spray, or fill and soak.
Vapor and film in one pass. Readings fall while the film is removed.

How the Vapor Comes Down

Flammable vapor comes off the liquid hydrocarbon left in a tank. Ventilation dilutes the vapor. Hasten Cleanse goes after the source.

1

Bonds to the hydrocarbon

Surfactants and fatty acids attach to the residue and the free product on walls, floor, and in sludge.

2

Raises the flash point

Bound hydrocarbon vaporizes more slowly. Less vapor is generated in the first place, so LEL and VOC readings fall rather than being blown out.

3

Lifts the residue

The same wash that suppresses vapor lifts the residue into a water suspension for the vac truck. Cleaning and degassing happen together.

4

Adds nothing flammable

Water-based, no flash point. Nothing in the tank got more dangerous because of the product.

Where It Is Applied

Pressure vessels and drums

Circulate at 1:20, or fill and soak where circulation is not practical.

NGL and LPG bullets

Spray or circulate; vapor suppression is the primary job.

Exchanger shells with hydrocarbon film

Circulate. Note, it lifts hydrocarbon film. It does not remove scale or fouling; that is a different chemistry.

Columns and towers

Spray trays and walls during washdown.

What Hasten Cleanse does not do

It is not a solvent and not a caustic. It will not dissolve, melt, or strip material that is physically bonded or baked onto a surface, scale, rust, hardened deposits, coatings. It lifts hydrocarbons, oil, grease, crude, sludge, and paraffin, by emulsifying them, and it needs agitation, circulation, pressure, or heat to do that work. If your problem is a stuck-on solid rather than a hydrocarbon film or residue, tell us and we will say so.

Concentrate and Packaging

One documented case beats every adjective. Ask for the demo on one vessel during the next outage and bring the meter.

No added bacteriaNothing in the pail is alive. Hasten Cleanse feeds the microbes you already have, in a treatment plant, a separator, or the soil, instead of competing with them.
Full concentrateSold as concentrate and diluted on site, 1:10 for heavy residue to 1:50 for light. Compare products by working gallons per drum, not by the drum.
No flash point, no placardsWater-based and non-flammable. Ships as standard freight in 5-gallon pails, 55-gallon drums, 275-gallon totes, and bulk. Gulf Coast delivery in one to two days.

Who Uses It, and How It Gets to the Job

Half the people who look up vessel degassing want someone to do the work. The other half want what the workers use. Hasten Cleanse is the second thing, and we can help with the first. We supply tank cleaning contractors, refinery turnaround crews, vapor control vendors, and plant maintenance departments across the Gulf Coast, and we ship the same concentrate to operators who run their own entry program.

Tank cleaning and degassing contractors

Crews that clean crude, product, slop, and produced water tanks add Hasten Cleanse to their circulation or spray water so the vapor space comes down while the residue lifts. One product covers the degassing step and the cleaning step, which is why contractors carry it in totes rather than two separate chemicals.

Refinery and terminal turnarounds

Entry permits wait on LEL, benzene, and H2S readings. A water-based vapor suppressant that bonds to the hydrocarbon lets the readings fall without steaming the vessel for days. Turnaround planners order by the tote and stage it at the unit before the outage.

Tanker trucks, railcars, and frac tanks

Transport tanks that switch products or go in for repair need the vapor knocked down before hot work. A 1 to 20 solution sprayed or circulated through the tank does it without a flammable solvent in the truck bay.

Pipeline and vessel cleanouts

Pigging, flushing, and vessel entry all end with the same question, what are the readings. Hasten Cleanse goes in with the flush water and leaves a non-hazardous rinse that can go to the wastewater system.

If you need a crew rather than a chemical

Ask us. Our customers are the contractors who do this work along the Gulf Coast, and we know who covers which plants and which districts. If you have a crew already, they can buy the concentrate from us direct; one tote covers a lot of tank bottoms at 1 to 20.

What the readings mean

LEL, lower explosive limit. The percent of the way to a flammable mix. Entry programs commonly want under 10 percent LEL. Hasten Cleanse brings it down by binding the hydrocarbon and raising the flash point of what is left, so the vapor stops coming off the surface.
Benzene and VOCs. The compounds that set respirator and permit rules. Suppressing the vapor at the liquid and on the wetted walls is what lowers the number at the meter.
H2S. Sour tanks carry it in the sludge. Field crews report that circulation with Hasten Cleanse lowers H2S readings along with the hydrocarbon vapor. Treat that as a field report, not a specification, and meter every tank.
Time to entry. Customers report entry times cut by as much as 80 percent against steaming. Your tank, your sludge, and your circulation rate set the real number, which is why we offer a demo on your tank.

Vessel Degassing Questions, Answered Straight

Does it remove exchanger scale or fouling?

No. It lifts hydrocarbon film only. Scale and fouling need a different chemistry or mechanical cleaning.

Sour service?

Customers report H2S dropping with LEL and VOC, and it handles iron sulfide residue. Pyrophoric precautions still apply.

Is it a substitute for steaming?

Some customers use it instead of, others alongside. Ask for a side-by-side on one vessel.

Flammable?

No. Water-based, no flash point.

Wash water?

Non-hazardous, and the fatty-acid base feeds the plant's biology. No added bacteria.
