light hydrocarbon of petrorefining nik yazd

The color of petroleum products is considered a very important quality parameter, as this parameter indicates the degree of purity of the product and this is important because it is easily observed by the buyer, which is one of the positive points of light hydrocarbon of Nik Yazd Petro Refinery Company. The color number of light hydrocarbon is in accordance with the standard in the range of (0-0.25). According to the result of this test, the color number of light hydrocarbon of Nik Yazd Petro Refinery is zero, which indicates the very high quality of the product

Mercaptan

“Mercaptan sulfur has an unpleasant odor and an incompatibility effect with the elastomers of the fuel system and is corrosive to the components of the fuel system. The presence of mercaptan in the final product reduces the quality of the final product, considering the high level of mercaptan in South Pars gas condensate and the emission of unpleasant odor during ground transportation and also during the distillation process and creating environmental problems, Nik Yazd Petro Refinery Company has established a mercaptan conversion unit in Pars Special Economic Energy Zone (Asaluyeh) to protect the natural and human environment.

Therefore, the feed required for refining, after performing the activities related to mercaptan conversion and removing the unpleasant odor from hydrocarbon components at Asaluyeh site, is transferred to the main unit in Yazd. The maximum amount of mercaptan in light hydrocarbon can be 150 ppm. The test report of light hydrocarbon of Nik Yazd Petro Refinery for mercaptan amount is 43 ppm.

Octan Number

The octane number scale is used to determine the quality and combustion efficiency of a fuel. The octane number test is performed in two ways: Research Octane Number (RON) and Motor Octane Number (MON). According to the standardization, the octane number test RON must be at least 78 and for the MON test at least 72. The light hydrocarbon product produced by Nik Yazd Petro Refinery Company, according to the results obtained, has a RON of 80 and a MON of 74.

Corrosiveness to Copper

Copper strip corrosion is applicable for petroleum products such as jet fuel and motor gasoline and other hydrocarbons that have a vapor pressure of less than 18 psi, which indicates the corrosion of petroleum products. This parameter is measured at 50 degrees Celsius and is in the range of 1a (lowest corrosion) to 4c (highest corrosion) which is announced according to the above figure. The result of the test on light hydrocarbon product of Nik Yazd Petro Refinery with code 64741-46-4 at 50 degrees Celsius is 2c.

Reid Vapor Pressure (RVP)

Vapor pressure is the pressure resulting from the equilibrium of liquid with liquid vapor. This method is used to measure the vapor pressure of gasoline, volatile crude oil and other volatile petroleum products. Performing the Reid Vapor Pressure test or RVP should be considered for safety reasons. The standard vapor pressure is a number between 45-60 kps, which is the result reported on the light hydrocarbon product produced by Nik Yazd Petro Refinery Company, 55 kps.
