Tank Cleaning: What Is It and How Do We Do It?

 Untitled design (21)-1

 Anyone who has ever owned a fish knows the necessity and the aggravation that comes with cleaning the tank. No one loves doing the job, but like the most important and strenuous tasks in life, it must be done. And in the refining industry, it is no different, except with our Manway Cannons and Centrifuges, the job just got a lot easier and with less headache for the operator.

What sort of tanks are we talking about here?

In many industrial settings such as petrochemical and refining, companies utilize large storage tanks to house their liquids.

These tanks aren't like your normal fish bowl. Most of the tanks used in this setting can be up to 12 million gallons in size.

Industry standards require these tanks to be cleaned in order to pass inspection.

So when should you have your tanks cleaned?

While certain situations may differ from industry or company, there are usually three main reasons why tanks must be cleaned.

  1. First and foremost, there may be damage to the tank or some sort of malfunction that must be repaired. Before repairs can take place, the tank must be emptied, cleaned, and all vapors removed prior to being safe enough for the repairman to enter.
  2. Second, you may need to change the contents of the tank from time to time. In order to prevent the previous contents from mixing with the new contents, such as with changing out refined products with unrefined products, all areas of the tank must be cleaned and all impurities and residue must be removed.
  3. And lastly, but certainly not least, tanks must also be cleaned prior to inspections. In order for a proper inspection to be completed, the tanks must be emptied, cleaned, and deemed safe enough for the inspector to enter unharmed.

So how exactly do tank cleaners get the job done?

After following all safety measures required by the specific industry standards, such as lockout/tagout procedures to prevent electrical hazards, and all materials have been drained from the tank, the cleaning crew will utilize a couple of pieces of equipment to make sure the job is done right:

1. The Manway Cannon: with an effective jet range 115 ft. it can clean more of the tank without having to relocate the cannon to another manway which can be limited.

2. RS-2100 3 Phase Decanter: not only does it have a very small foot print to set up, but it also contains a fully automated effluent pump system with 500 gallon tank.
