Analysis of the quality of LPG and petroleum products at in-house laboratory

In order to control the quality of products, the gas filling station is provided with an in-house laboratory equipped with state-of-the-art equipment.

The following types of tests are performed at the in-house laboratory:

Liquefied petroleum gases:
  1. Determination of hydrocarbon composition of liquefied petroleum gases by gas chromatography method;
  2. Determination of total sulphur content by ultraviolet fluorescence method;
  3. Determination of corrosion on a copper plate;
  4. Determination of density (calculation method);
  5. Determination of saturated vapour pressure (calculation method).
Highly flammable liquids:
  1. Determination of density using a density meter;
  2. Determination of fractional composition;
  3. Determination of the flash point in a closed cup;
  4. Determination of total sulphur content by ultraviolet fluorescence method;
  5. Determination of cloud point and gel point;
  6. Determination of cold filter plugging point (CFPP).
