Power Plant Cleaning

Power Plant CleaningPower plant cleaning often calls for recoating and refinishing of tanks, pipes, and other areas in and around the plant. As the paint coating wears off, it corrodes and eventually needs replacing. Another common problem with power plant equipment involves mineral deposits that can collect on clarifiers, pipes, floor tanks and other surfaces.

Waterblasting.com, Inc. offers services to remove both coatings and mineral deposits in a safe, convenient, and effective method that employs the use of water blasting or ultra-high pressure (UHP) equipment.

Our technicians use systems that are capable of removing all types of paint – epoxy, enamel, urethane, and more – as well as mineral deposits like calcium all using environmentally friendly water.

Our water blasting systems all function under pressures ranging from 10,000 – 40,000 psi with flow ratings of 6-100 gallons per minute. The unique vacuum recovery feature on every piece of equipment allows not only a cleaner, safer worksite by eliminating debris, but also helps minimize our time on the job site.

We can remove any coating and all deposits from any equipment surface whether it is steel or concrete. Our technicians use ultra-high pressure water systems that work quickly and efficiently to remove the unwanted coatings with ease.

This past October, Mosaic Crop Nutrition had a planned maintenance project on a sulfur tank in their Channelview, Texas warehouse. CCC Group, Inc. out of Bartow, Florida was charged with the task, but before they could properly service the tank, solid sulfur remnants calculated at 8”-10” thick needed to be removed, which would prove both difficult and time consuming. CCC Group estimated two weeks’ time for the job, with a round-the-clock schedule, and tapped waterblasting.com for the demanding removal and cleaning project.

Upon Waterblasting.com’s arrival at the job site, the South Florida technicians realized everything really was bigger in Texas – including the scope of their project. The tank had been drained prior to job commencement, but the 8”-10” of sulfur turned out to be more like 28”-32” – a significant difference.
What’s more, Jack Dye of Mosaic Crop Nutrition cautioned the operators that there was a possibility that some of the molten sulfur may not have cooled completely. “We were going to be working in hell,” said Waterblasting.com’s Brent Hoffpauir, who was onsite throughout the project.

Hoffpauir’s fire and brimstone reference wasn’t that farfetched. Using a waterjet abrasive cutter, the Waterblasting.com crew began by cutting a 12’X15’ doorway into the tank to gain access. The bottom edge of the cut was planned to be 12” off the bottom, but had to be adjusted to 32” because of the potential for molten sulfur pockets. Once the door sheet was cut and removed, Keith Parma, Project Superintendent from CCC, inspected the tank and determined the Waterblasting.com crew would have to remove the top layer of sulfur before they could tell if there was indeed molten sulfur to consider. Upon removal, with a combination backhoe loader, sure enough, the crew was met with the heat and smell of liquid sulfur. ‘Hell’ was translating to be a more literal term than they’d anticipated. It was becoming obvious: there was nothing typical about this job.

Power Plant CleaningThe unexpected molten sulfur, along with the underestimated levels were serious hindrances to the project timeline. They easily tripled the scope of Waterblasting.com’s work, and, one might assume, the completion time. Doubt crept in, as CCC and Mosaic both wondered just how far the extra sulfur would
set back the project. But true to Waterblasting.com modus operandi, the Waterblasting crew disregarded doubt, and the setback. There was a job to be done after all.
Waterblasting.com got to work. Liberal amounts of water were used to cool the sulfur, ultimately solidifying it so that the crew could remove, and then properly dispose of it. The team worked day and night alongside a safety crew from CCC that was in place to ensure the hazardous gases of hydrogen sulfide and sulfur dioxide did not pose a noxious threat. Personal air gauges were worn by all contractor personnel, and air levels were carefully monitored. Although a few alarms sounded throughout the process, all escaped unscathed, and the project was a true success. The Waterblasting.com crew was able to complete their portion of the tank cleaning in fewer than three and half weeks, a far cry from the possible six weeks it was estimated to take.

The Waterblasting.com crew stayed focused and driven, concentrating not on obstacles, but on solutions. They were able to complete the intimidating job, and wrapped up in nearly half the time expected. Upon finishing their project at Mosaic Crop Nutrition, Brent Hoffpauir and team left exhausted, but proud of their job well-done. “Our crew packed up and headed home for a well deserved rest,” says Hoffpauir. After three and a half weeks in hell, it was well deserved indeed.
