Resolve phase separation & contamination issues

Tank cleaning & fuel restoration

Fuel storage tanks containing free water, phase separation contamination and degraded fuel can be a costly nightmare for fuel retailers and commercial fuel users. Leighton O’Brien provides a comprehensive solution for removing contamination and free water as well as a patented process for restoring fuel quality and remediating phase separation.

Unlike other tank cleaning services, our technology sweeps the entire tank floor to remove contamination and free phase water from the tank. Our patented process restores and returns 100% of the useable fuel.

The flexibility of our technology means we can customise our service to meet our clients’ tank cleaning and fuel restoration requirements – whether it be fast and cost effective water removal through to a comprehensive 3-stage tank clean and fuel restoration service to ensure premium fuel quality at all times.

We also provide a full service report including product quality check and fuel inspection report on all tanks.

Leighton O’Brien’s tank cleaning and fuel restoration technology means you can:

  • Improve the cost effectiveness of free phase water removal from tanks
  • Remediate phase separation
  • Eliminate costly insurance claims from vehicles breaking down
  • Kill and remove microbial growth and the environment they live in
  • Reduce the reoccurrence rate of microbial growth to almost zero
  • Eliminate problems with blocked filters
  • Improve the functionality of pumps and ATGs
  • Eliminate power outages involving critical emergency power backup systems
  • Remediate and re-sell degraded fuel stock

The Leighton O’Brien advantage

Tank cleaning and fuel restoration has evolved significantly over the last decade. In years gone simply pumping free water from the tank floor was considered a sufficient method of maintaining a ‘clean tank’, which slowly evolved into one of the many variants of fuel filtration.

Leighton O’Brien’s patented technology changes customer expectations. With the introduction of ethanol, biofuels and modern additives, simply filtering the fuel is no longer enough to offer a premium tank cleaning and fuel restoration service.

Phase separation: Leighton O’Brien’s tank cleaning and fuel restoration technology removes free water and remediates the remaining phase separated fuel to a saleable condition without additives. Using Leighton O’Brien you do not need to dispose of your phase separated fuel or dose it with unproven additives. Leighton O’Brien can restore your fuel to a refinery specification.

Microbial contamination: Many commonly occurring microbes in petroleum products grow in the water/fuel interface or in sludge on the tank floor. Biocide, applied correctly, is a very effective means of killing the existing microbial growth in your tanks. However, by killing the microbial growth in the tank you’re enhancing the environment for new bacteria to grow.  Leighton O’Brien’s tank cleaning and fuel restoration process will remove 100% of the microbial growth and the environment in which microbial activity can flourish hence eliminating the potential for reoccurrence.

Degraded diesel: Our process can recondition and restore aged, degraded diesel fuel to clean, dry and on specification fuel. The risks of ageing diesel fuel is well known and many of our existing customers engage us to annually recondition and regenerate their backup fuel supply, saving thousands of dollars in fuel replacement costs.

How it works

 Case study: phase separation

Our client removed 21,000 litres of phase separated fuel from an underground storage tank and had planned to dump the fuel. Using market-leading patented fuel restoration technology, Leighton O’Brien processed the fuel while it was stored in a 5 compartment tanker to an on spec octane level of 87.

Prior to the clean there was a significant volume of free water on the tanker floor. After the treated fuel was returned to the UST, the E10 fuel was dosed with a small amount of premium 92. At $1/litre fuel cost this job saved the customer more than $15,000 if they had chosen to dump the fuel.

Global fuel retailers trust Leighton O’Brien to restore phase separated product to dry and correct octane levels, convert their entire network to E10 without phase separation issues, address wide bacterial contamination issues, manage fuel quality programs and provide independent fuel sampling to thousands of underground storage tanks.

Case study: degraded diesel

Our Licensed Service Partner, Seneca Waste Solutions, had a customer with several trucks that experienced problems after purchasing contaminated diesel fuel from a private client. The client was unaware the fuel was dirty. As a result of the contamination, the client had to pay for repairs for the damage to the vehicles.

To resolve the situation, Seneca was initially asked to do a fuel sweep on the tank. The fuel sweep utilizes a vacuum truck to remove water from a tank. Upon consultation with Seneca’s fuel polishing team, it was determined that a better course of action would be to perform fuel restoration on the tank. Unlike other tank cleaning services, Leighton O’Brien’s market-leading technology removes only liquid waste from tanks – not fuel.

Seneca’s team arrived on site with a Leighton O’Brien patented fuel cleaning truck. Initial fuel samples showed a significant amount of water, debris and bacteria build up in the tank. Seneca’s team completed fuel restoration services in just a day, allowing the client to sell clean fuel with minimal downtime soon after.

Leighton O’Brien delivers on every level. They beat the competition on accuracy, they deliver support and innovation that matches our own and they help us make a difference in our sector.
