Fuels Analysis 

Fuel properties are controlled by fuel standards and specifications which allow for the manufacture of consistently fit-for-purpose fuels that comply with all legislative controls and internal performance criteria.

A rigorous quality control system is applied to all tests and procedures to ensure that all aspects of method requirements are met. In New Zealand these are the Engine Fuel Specifications Regulations 2011 and IPL takes great care to ensure methods and guidelines are respected. The range of fuels testing we specialise in are:

Diesel or Automotive Gas Oil (AGO) is made from a mixture of heavy, light, hydro-cracked and de-sulphurised gas oils that result from the refining of crude products. It is manufactured mainly for automotive use but can also be utilised in diesel turbines for electricity production, railways, the marine industry and heating and furnace applications. As cross-mixing and water can contaminate the fuel, the most common diesel testing required is investigating contamination.
Petrol or automotive gasoline
Petrol is a volatile, flammable liquid obtained from the refinement of petroleum, or crude oil. It was originally discarded as a by-product of kerosene production, but its ability to vaporize at low temperatures made it a useful fuel for many machines. Petrol contamination can come from the cross-mixing of different fuels. Tests such as octane ratings and ethanol content can identify contamination.
Aviation gasoline (Avgas)
Avgas is currently used in small aircraft with piston engines. These engines operate using the same basic principles as spark ignition engines of motor cars but they have a much higher performance requirement. Avgas is the most restrictive fuel produced in a refinery because of the stringent and sometimes conflicting requirements.
Jet Fuel (Jet A-1)
Made from the lighter middle distillate fuel streams in the refinery. They are mixtures of the straight-run (non-cracked), hydrotreated and hydrocracked kerosenes. Excessive use of hydrocracked components has led to lubricity problems. Jet Fuel specifications include not just tests and limits but other related items including manufacturing, traceability, additives and contamination. 

Fuel Oils

Fuel oils are manufactured by blending distillation residues with gas oil components according to market requirements. Fuel oils are mainly used to drive engines used in heavy industry applications such as for power generation, steam generation, ship fuel and industrial burners. A range of different fuel oils are manufactured, according to the requirements of the end user.

Waste Oils
A common trend is to use waste oils to fuel industrial burners. To aid the longevity of typical burners and to minimise potential damage caused by oils, it is crucial to test for contaminants such as Ash, Sediment, Water, PCBs, Heavy metals and Halogens. It is also tested for sulphur for emission purposes.

Solid Biofuel - Heavy Metals and Hg Analysis

The determination of heavy metals can be helpful to predict potential contamination caused by combustion of the biofuel. If ashes are to be put back in the forest as fertiliser, it’s important to be aware of those elements that can be harmful to the environment. Regular checks can be useful to help identify purity of the product.

IPL can test your solid biofuel by ICP for Arsenic, Boron, Chromium, Copper, Lead and Zinc and uses its DMA to quantify Mercury to a sensitivity of 20ppt (ng/kg)

Although these test currently aren’t part of the Technical Guide for standard testing methods for solid biofuels, they help assess the quality and purity of the solid biofuel.

If you wish to include as part of your quality assurance testing schedule, please contact us.
