BP’s advice on long term storage of diesel
IPU isn’t the only company advising that modern diesel has what can best be described as a ‘shelf life’. Even the fuel companies supplying the diesel agree. BP has issued a document detailing best practice for the long term storage of diesel.
BP notes that:
- Under normal storage conditions diesel fuel can be expected to stay in a useable condition for:
- 12 months or longer at an ambient of 20ºC.
- 6-12 months at an ambient temperature higher than 30ºC.
- The ageing process can be accelerated by:
- The presence of water. Water allows the growth of fungus and bacteria. These produce natural by-products such as organic acids which make the fuel unstable.
- Exposure to dust and dirt which contain trace elements that can destabilise the fuel such as copper and zinc.
- Fuel composition. Some components in diesel fuel (especially biodiesel) naturally age quickly.
Under normal storage conditions diesel fuel can be expected to stay in a useable condition for just 6-12 months.
Two short videos illustrate the nature and solution to fuel contamination issues.
All the contamination problems found during the long term storage of diesel can be addressed by implementing a fuel conditioning programme. IPU’s four-part process covers:
