LPG / GASOIL ( ULSD / EN590)
LPG - General Reference Specification
About LPG - Liquid Petroleum Gas
LPG is a collection of hydrocarbon gases that have been compressed into a liquid state for convenience of storage and transportation, mainly Propane (C₃H₈) and Butane (C₄H₁₀). These gases are either naturally present in natural gas deposits and crude oil, or they are created when crude oil is refined. LPG is convenient to store in pressurized containers since it takes up significantly less space when liquid than when gaseous.
Natural gas and crude oil are the sources of liquefied petroleum gas. It is made up of hydrocarbons with perhaps three or four carbon atoms. This mixture contains hydrocarbon gasses and is combustible. However, the typical components of LIquefied Petroleum Gas are Propane (C₃H₈) and Butane (C₄H₁₀). There may also be trace amounts of other Hydrocarbons. Hydrocarbon Gases included in this flammable mixture are used as fuel for culinary appliances, automobiles, and heating appliances. It has two percent pentane, fifty percent butane, and forty-eight percent propane.
Mixtures that comprise mostly Propane and Butane, as well as occasionally combinations of both Propane and Butane, are among the types of LPG that are purchased and sold. Mixtures of Propane are more common in winter regions, while Butane is more prevalent in summer regions. Grades range from HD-5. Small amounts of other hydrocarbons, including Propylene and Butylenes, Methane (CH4), Propane (C3H8), and ethane (C2H6), are also found. Ethanethiol, a potent odorant, is added to LPG to make leaks easier to find.
Because it burns easily in the air and has an energy content comparable to that of gasoline and double that of natural gas, Liqueied Petroleum Gas (LPG) is a great fuel for heating, cooking, and automobiles.
The LPG Production Process
LPG is either extracted as a byproduct of processing natural gas or during the refining of crude oil. The production process is broken down as follows:
1. Natural Gas Processing: Methane, Propane, Butane, and other gases are among the components of natural gas that are recovered from the earth. Fractionation is the process by which the heavier Hydrocarbons, such as Butane and Propane, are separated from the Methane, which is the primary component of natural gas.
2. Crude Oil Refining: When heavier Hydrocarbons are refined into lighter products like Gasoline and Diesel, LPG is created as a byproduct. During the distillation process, it is sorted out. .
About GASOIL / ULSD / AGO / EN590 - 10PPM
EN590 describes the Physical Properties that all Automotive Diesel Fuel MUST MEET if it is to be sold in the European Union, Croatia, Iceland, Norway and Switzerland.
The EN 590 had been introduced along with the European Emission Standards. With each of its Revisions the EN 590 had been Adapted to Lower the Sulphur Content of Diesel Fuel EN590 – Since 2007 this is called ULTRA LOW SULPHUR DIESEL (ULSD) as the former function of Sulphur as a Lubricant is Absent (and needs to be replaced by additives).
The quality of European diesel fuels is specified by the EN 590 standard. While these specifications not are mandatory, they are observed by all fuel suppliers in Europe.
Automobile Diesel EN 590 is intended for application in diesel engines. Diesel motor fuel quality meets the requirements of European Standard EN 590. For operation in the conditions of a temperate climate following marks of fuel diesel automobile EN 590 are offered: Grade C – limiting filterability temperature -5 ° C; Grade D – limiting filterability temperature -10 ° C; Grade E – limiting filterability temperature – 15 ° C; Grade F – limiting filterability temperature -20 ° C. The entire volume of produced diesel fuel quality meets the requirements for fuels for vehicles of Euro 4 and Euro 5. Low sulfur content in diesel EN 590 reduces emissions of sulfur oxides into the atmosphere, which is especially important for inhabitants of big cities.
ULTRA LOW SULPHUR DIESEL (ULSD) is diesel fuel with Substantially Lowered Sulfur Content. Almost all of the petroleum-based diesel fuel available in majority countries is of a ULSD type. There is not a single standard set of specifications and as the government mandated standard becomes progressively more strict so does the definition.
The move to lower sulfur content is expected to allow the application of newer emissions control technologies that should substantially lower emissions of particulate matter from diesel engines. Testing by engine manufacturers and regulatory bodies have found the use of emissions control devices in conjunction with ULSD can reduce the exhaust output of ozone precursors and particulate matter to near-zero levels.
Sulfur is not a lubricant in and of itself, but it can combine with the nickel content in many metal alloys to form a low-melting eutectic alloy that can increase lubricity. The process used to reduce the sulfur also reduces the fuel's lubricating properties. Lubricity is a measure of the fuel's ability to lubricate and protect the various parts of the engine's fuel injection system from wear.
ULSD fuel has enabled the use of cleaner technology diesel engines and vehicles with advanced emissions control devices, resulting in significantly improved air quality.
