Petroleum Products Testing Information

DEEPA ENTERPRISES TESTING LABORATORIES is the firm for Quality analysis of crude oil, crude oil fractions and distillates
Petroleum testing involves quality analysis of petroleum products during upstream, midstream, and downstream production processes. Analyses include crude oil composition, crude oil fractions, analysis of fuel additives and oil contaminants.

Petroleum, which literally means 'Rock Oil' or 'Oil from the Earth', was formed from the remains of plants & animals that lived millions of years ago (Pre-Dinosaur age) in a marine environment. Subsequent decomposition of those remains (over millions of years) by application of heat & pressure (due to burial) by deposition of sand & silt over them led to the formation of 'Crude Oil' or Petroleum. It is one of the 3 Fossil fuels, viz., Coal, Natural Gas, Petroleum, that occur in our nature, & is composed of a complex mixture of different types of hydrocarbons along-with a number of elemental impurities, like Sulfur, Nitrogen, Oxygen, etc. Due to wide variations in the origin of Petroleum products, they vary considerably in terms of their Physico-Chemical properties & appearances, from one Oilfield to other.

Techniques that separate and arranges according to size, ferrous wear particles from a lubricant for analysis with a microscope. The Ferro gram provides information for the identification of wear particle types and a description of the wear mode that generates the particles.

Viscosity is one of the most important properties of a lubricant as it determines both the film thickness of the oil and how readily the lubricant will flow into the narrow area separating the moving metal parts.

The primary use of this method is for viscous materials (excluding fuels) having flashpoints of 79°C and above. This test determines the temperature at which the oil will form a flammable mixture with air. The flashpoint can be compared with specification standards to determine if the oil meets the specification. It is often used as an indicator of fuel dilution.

Fire point:
The fire point is a measure of the tendency for the oil to support combustion.

DEEPA ENTERPRISES TESTING LABORATORIES provides an outstanding platform for carrying out tests of almost all the recognized elements of the periodic table. Whether the sample is a metal or a non metal or an alloy, we are fully equipped with all the instruments required for its quantitative as well as qualitative analysis. We practice traditional techniques like Wet Chemical Methods and also the instrumentation techniques for studying the prescribed parameters.

The separation of Crude Petroleum into its various individual fractions (called 'Petroleum Products'), like Petrol, Diesel, & Naphtha, take place in a 'Petroleum Refinery' by a process called "Refining", which consists of 3 steps: (1) Separation (2) Conversion & (3) Purification. There are 4 major types of Petroleum fractions, depending upon their Chemical Bonding patterns:

(1) Paraffins (2) Olefins (3) Naphthenes & (4) Aromati

Depending upon their usage, Petroleum Products can be broadly divided into 2 types, 'Fuel Oil' & 'Lubricants'. Characterization of these products in terms of a number of Physico-Chemical properties, like Viscosity, Octane number, Cetane number, Distillation range, is of utmost importance in determining the suitability of a particular Petroleum Product for the purpose of its intended use, transportation, storage, & other functions

DEEPA ENTERPRISES TESTING LABORATORIES Analytical Labs Ltd. has been serving its elite group of customers (in the Petroleum & Allied Industries) for well over a decade, by providing reliable & meaningful test results. It can also conduct customized tests, depending upon a client's specific needs. DEEPA ENTERPRISES TESTING LABORATORIES's credibility lies in its strict adherence to Quality Control Procedures (as per ISO 17025:2005), & its team of efficient & well-trained technicians/analysts who are well-equipped with the most sophisticated & versatile analytical instruments, to test a wide variety of Petroleum Products.
