The Importance of Cetane Number in Diesel Fuel

AONG manager

What is Cetane Number? Cetane Number is a measure of the ignition quality of a diesel fuel. It is often mistaken as a measure of fuel quality. Cetane number is actually a measure of a fuel’s ignition delay. This is the time period between the start of injection and start of combustion (ignition) of the fuel. In a particular diesel engine, higher cetane fuels will have shorter ignition delay periods than lower cetane fuels. Cetane number should not be considered alone when evaluating diesel fuel quality. API gravity, BTU content,…

what does Erosion-Corrosion mean

AONG manager

Erosion-Corrosion Likelihood– ?API RP14-E is not valid in presence of solid particles (sand)– ?It is not valid in vertical flow (even if it is used as well)– ?It is not valid for gas systems (where no definite velocity limits are identified).– Alternative models have been proposed (as SalamaModel)/ or typical critical flow velocities based on experience are often used in design as an optional approach to API Model.Erosion-Corrosion– its attacks occur when the corrosion process is associated with severe fluidynamic conditions, i.e. very high flow velocities, that give rise to…

Lubricating Oils Testing Methods

AONG manager

INTRODUCTIONLubricating oil is used to reduce friction and wear between bearing metallic surfaces that are moving with respect to each other by separating the metallic surfaces with a film of the oil. Lubricating oil is distinguished from?other fractions of crude oil by a high (>400°C/>750°F) boiling pointIn the early days of petroleum refining, kerosene was the major product, followed by paraffin wax wanted for the manufacture of candles. Lubricating oils were at first by-products of paraffin wax manufacture.The preferred?lubricants in the 1860s were lard oil, sperm oil, and tallow, but…

Corrosion and Corrosion Inhibitors

AONG manager

CorrosionCorrosion is defined as the destructive attack of a metal by the environment, by chemical or by electrochemical processes (as contrasted with mechanical means such as the erosion of a metal structure by sand in the desert). Corrosion includes conjoint mechanical and chemical action to produce early failure of a load-carrying metal structure, eg. stress-corrosion cracking.see our How Corrosion Happens in Oil and Gas IndustryManifestations of Corrosion Most of the observed corrosion occurs as one or more of the following five cases:(1) uniform attack, the most common manifestation, in which…

Scale and Sclae Inhibitors

AONG manager

?what is Scale?Scale is normally a buildup of salts of calcium, barium or strontium as calcium carbonate, barium sulfate and strontium sulfate. Carbonate scale is caused by the presence of calcium and bicarbonate ions in the formation water. When pressures are decreased or temperatures are increased, the bicarbonate will begin to decompose, resulting in pH increases and calcium carbonate precipitation in the form of scale.Barium and strontium sulfates form in wells that produce waters naturally saturated with barium or strontium sulfates, or when produced water containing barium or strontium is…
