Our Blending System

We have the capability of blending your heavy paraffin and asphaltic type tank bottoms with crude oil, as the tank is being cleaned, and pumping the blended mix back into your line or another tank.

  • We recognize that many customers would prefer to keep their tank bottoms in their system if possible. However, they don’t want to transfer the problem to another tank and hope the tank mixers make it disappear. Drawing from our experience in the oil reclamation business, we have developed a blending system that will allow the tank bottoms to be mixed with oil at a precise ratio, filter out any debris and pump the homogenous blend into your pipeline or adjacent tank. The advantages of using our blending system include:
  • No inventory loss
  • Limits environmental liability
  • No trucking expenseRepositioning Roof Support Legs on Internal Floating Roofs
  • Reduces down time for tank cleaning crew
  • Strains out debris
  • Reduces the likelihood of downstream equipment damage due to debris
  • Mixes the tank bottoms with your crude oil to the optimum ratio
  • Reduces viscosity by passing the combination through a static mixer
  • Strains out debris and eliminates solids larger than 1/32″ diameter
  • Passes the mix through a high speed blender, adding tremendous mechanical shear and creating a homogenous blend
  • (Optional) Provides chemical injection that is used to disperse paraffin and asphaltines and increase the stability of your blend
  • Repositioning Roof Support Legs on Internal Floating Roofs

A specialty service offered by Midwestern is to provide trained personnel and equipment to enter a tank through a man-way on the fixed roof and descend to the internal floating roof. A man-lift tripod and winch with backup fall protection is used and all entrants wear supplied air respirators with two backup air supplies. Roof support legs can be re-pinned in the high position to allow an adequate roof height for scheduled maintenance or re-pinned in the low position to allow drawing the product down to a lower level without repeatedly “landing” the roof.

Removing Collapsed Internal Floating Roofs

A specialty service offered by Midwestern is removing collapsed aluminum or fiberglass internal floating roofs. This can be a challenging and expensive task for the inexperienced. Most repair contractors will not work inside a tank until it is gas-free. Let a Midwestern representative help you find the most economical way to remove and dispose of your collapsed roof and get your tank clean and gas-free.
