What is Ron in naphtha?
While light naphtha has mostly paraffins, heavy naphtha has around 12% of aromatics and olefins. The Research Octane Number (RON) and Motor Octane Number (MON) are 66 and 62 for light naphtha and 62 and 58 for heavy naphtha, respectively, note Chang et al.
What is the composition of naphtha?
Naphtha contains varying amounts of paraffins, olefins, naphthene constituents, and aromatics and olefins in different proportions, in addition to potential isomers of paraffin that exist in naphtha boiling range.
What is paraffinic naphtha?
Paraffinic Naphtha means liquid hydrocarbons known as condensate and recovered from natural gas liquids at the Plant, and any reference to Product in this Contract shall include Paraffinic Naphtha.
What are the properties of gasoline?
The most important properties of gasoline fuels are properties such as volatility and knocking resistance, whereas diesel fuels are required to have important fuel properties such as viscosity, surface tension, and ignition tendency.
How is Ron calculated?
Research Octane Number (RON) RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane.
What is meant by Ron?
What does the RON number mean in regard to petrol? Unleaded fuels carry a RON (Research Octane Number) rating. Put simply, RON determines petrol’s ‘anti-knock’ quality or resistance to pre-ignition; or if you want to put in another way, the Octane Number denotes its resistance to detonation.
What does 98 RON mean?
octane rating number
Fuels such as 95 or 98 RON (octane rating number) have a higher resistance to burn which indicates higher levels of energy available for the vehicle’s engine.
What is Ron in gas?
Octane Number (RON, MON) & Knock Resistance. The octane number (ON) is a measure of the knock resistance of gasoline. It defines a numerical value from 0 to 100, and describes the behavior of the fuel in the engine during combustion.
What is naphtha and its uses?
naphtha, any of various volatile, highly flammable liquid hydrocarbon mixtures used chiefly as solvents and diluents and as raw materials for conversion to gasoline. Naphtha was the name originally applied to the more volatile kinds of petroleum issuing from the ground in the Baku district of Azerbaijan and Iran.
What are the main uses of naphtha?
The main uses of petroleum naphtha fall into the general areas of (i) precursor to gasoline and other liquid fuels, (ii) solvents (diluents) for paints, (iii) dry-cleaning solvents, (iv) solvents for cutback asphalts, (v) solvents in rubber industry, and (vi) solvents for industrial extraction processes.
What are the 3 properties of gases?
Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form. An internal combustion engine provides a good example of the ease with which gases can be compressed.
What is a visbreaker in an oil refinery?
A visbreaker is a processing unit in an oil refinery whose purpose is to reduce the quantity of residual oil produced in the distillation of crude oil and to increase the yield of more valuable middle distillates ( heating oil and diesel) by the refinery.
Is naphtha a high or low value hydrocarbon?
The visbreaker naphtha (VN), a product of the visbreaking unit [1], [2], is usually considered a low value hydrocarbon stream [3], [4], [5], [6] due to its low octane number [2] and high sulfur content.
How was the proportion of visbreaker naphtha selected for diesel production?
The proportion of visbreaker naphtha was selected according to the production of this naphtha and of straight run gas oil in a typical refinery. The hydrotreated product was stabilized at different cut points and a target cut point was selected for maximum diesel production, meeting all the product specifications.
What happens to the residue from a visbreaker?
The visbreaker residue is steam-stripped at the bottom of the fractionator and pumped through the cooling circuit for further processing. Visbreaker gas oil, which is recovered as a side stream, is steam-stripped, cooled and sent for further processing.
