Why is it important to remove metals from crude oil?
The presence of metals in crude oil during subsequent processing may cause corrosion, environmental pollution, and may poison the catalysts used. The metals may also interfere in oil refining processes by causing excessive coke formation.
What are the benefits of oil refining?
Refining and processing reduce the environmental impact of oil- and gas-derived fuels by removing harmful pollutants and improving their reliability during combustion.
How is heavy crude oil treated?
There are several methods in practice to reduce the viscosity of heavy crude oils in an effort to increase their mobility. These methods include (i) heating, (ii) dilution with light liquid hydrocarbons, (iii) oil-in-water emulsion formation, and (iv) depression of pour point [5, 6].
Why is it important to remove the sulfur compounds from crude oil?
For crude oil, reducing the sulfur content in gasoline and diesel improves emission controls. The sulfur recovery process removes sulfur compounds from the product and thus reduces air pollution created by the fuel combustion process when the products are used.
What are the impurities in crude oil?
Of the three major impurities, sulfur, nitrogen, and oxygen, sulfur is seldom absent from crude oil and can be found even in minute amounts. However, crude oil seldom has surfur concentrations greater than 3% with the higher concentrations restricted to heavy crude.
Why is it necessary to refine oil before it is useful?
Crude oil cannot be used as it occurs in nature, other than burning for fuel, which is wasteful, It must be refined to manufacture finished products such as gasoline and heating oil.
How does oil refining negatively affect society?
Oil refineries are major polluters, consuming large amounts of energy and water, producing large quantities of wastewaters, releasing hazardous gases into the atmosphere and generating solid waste that are difficult both to treat and to dispose of.
What is the difference between refinery and petrochemical?
Refineries focus on fuels production. Refinery products include LPG (liquefied petroleum gas), gasoline (petrol), kerosene and jet fuel, diesel, fuel oils, and coke. Petrochemicals focus on creating intermediates used to produce industrial and consumer products.
What are the methods of treatment of crude oil products?
Our crude oil treatment technologies include multiphase separation systems, dehydration and desalting electrostatic treaters, and distillate treaters.
Which is better heavy or light crude?
Light crude is typically more valuable, easier to refine, and contains greater quantities of hydrocarbons than heavier variants.
What is difference between light and heavy crude?
The higher the number, the lighter the oil; any liquid with an API gravity higher than 10 is lighter than water. Crude oil with an API gravity less than 30 is considered “heavy”, and oil with an API gravity greater than 30 is “light”. Most grades have an API gravity between 10 and 70.
What is the treatment of crude oil?
Treatment of crude oils. 1. TREATMENT OF CRUDE OILS. 2. PRETREATMENT OF CRUDE OILS • Crude oil comes from the ground, which contains variety of substances like gases, water, dirt (minerals) etc. Pretreatment of the crude oil is important if the crude oil is to be transported effectively and to be processed without causing fouling ...
What temperature does preheated crude go to?
The preheated crude having temperature of about 180o C is goes to pre flash drum where about 3-4percent of light ends are removed. The preheated crude from the preheater section is further 206 heated and partially vaporized in the furnace containing tubular heater.
What is the process of desalting oil?
Desalting process • Desalting process is used for removal of the salts, like chlorides of calcium, magnesium and sodium and other impurities as these are corrosive in nature. The crude oil coming from field separator will continue to have some water/brine and dirt entrained with it.
What is crude oil pretreatment?
Crude oil pretreatment. Crude oil often contains water, inorganic salts, suspended solids and water-soluble trace metals. The first step in the refining process is to remove these contaminants by desalting (dehydration) in order to reduce corrosion, plugging and fouling of equipment, and to prevent poisoning the catalysts in processing units.
What is the process of desalting crude oil?
Chemical desalting, electrostatic separation and filtering are three typical methods of crude-oil desalting. In chemical desalting, water and chemical surfactants (demulsifiers) are added to the crude oil, heated so that salts and other impurities dissolve into the water or attach to the water, and are then held in a tank where they settle out.
What is added to water wash to reduce corrosion?
Caustic or acid may be added to adjust the pH of the water wash, and ammonia added to reduce corrosion. Waste water, together with contaminants, is discharged from the bottom of the settling tank to the waste water treatment facility.
When to add surfactants to oil?
Surfactants are added only when the crude oil has a large amount of suspended solids. A third, less common process involves filtering heated crude oil using diatomaceous earth as a filtration medium.
What is in the waste water of desalting sour oil?
Depending on the crude feedstock and the treatment chemicals used, the waste water will contain varying amounts of chlorides, sulphides, bicarbonates, ammonia, hydrocarbons, phenol and suspended solids.
Pyrolysis And Crude Oil Sludge
One of the easiest ways to treat this sludge is to use a process called pyrolysis. This is a process which involves super heating the sludge in the absence of oxygen. This is done in a large container where the chemical composition of the sludge will be broken down into component parts. Each of these parts can then be used for beneficial purposes.
Crude Oil Sludge Process Plant
These machines consist of several different components which include the oil condenser, reactor, hydrocele, de-dusting system and the oil tank. These all work continuously, ensuring that it will eliminate the waste product, breaking it down into usable components.
How The Process Works
The sludge is actually deposited into a large drum. This is then placed into a centrifuge. Once the process has started, the sludge will be transformed into solids that will settle at the bottom of the large tank in the waste processed through the centrifuge.
How to treat oil?
Heat Treatment. Heat can be applied to oil as a way of reducing its viscosity, so that it floats to the top of the water. Heater-treaters are vessels that use heat from a firebox to aid in treating oil. The firebox may only be lit during colder months, and heat from the sun used in warmer months.
Why do wells need more chemical?
In higher producing wells, using more chemical may be necessary in order to speed up the separation process. Wells that only produce small amounts may have more time to treat the oil, and are able to let gravity and motion do more of the work.
Why is it important to use the amount of time you have?
The amount of time you have should be used wisely, as it’s a limited resource which depends on the well’s production rate. Wells that have higher production rates will sell oil more quickly, and so the oil will have less time to sit and separate. Higher production means more money for other methods.
What is it called when oil separates from gas?
If separation happens in just a few moments or minutes, as when gas separates from fluid, it’s called flash separation. Separation that takes longer is called slow separation. Depending on how the well is producing, ...
Does gravity remove oil?
With the emulsion coming from the well, the different elements are obviously mixed much more thoroughly. Gravity will do a lot to remove the heavier parts, the free water and sediment, from the oil. Over time, however, gravity will become less effective. Bigger water droplets fall out of the oil more easily, but smaller droplets tend ...
Does oil float on water?
Even the heaviest elements of oil are lighter than water. As a result, oil will float on top of water. You can see this for yourself by pouring a glass half full of water, and then pouring vegetable or olive oil on top. The division between the two will be very apparent.
Can oil and water be mixed together?
However, because of their different weights and densities, they will gradually separate over time. Again, you can see that by mixing the oil and water in the glass together.
What is crude oil?
Crude oil is a naturally occurring mixture of hydrocarbons found underground. It can appear in the form of a highly viscous liquid to a thick tar-like substance. The color of crude oil can also range from light yellow to dark brown or black. It is one of the most widely used fuel sources around the world, and oil, as well as oil derivatives.
How does crude oil contribute to the world?
Globally, crude oil is one of the most important fuel sources and, historically, has contributed to over a third of the world’s energy consumption. Discovering, extracting, shipping, and refining crude is a long process, and the infrastructure needed to support the process must be in place.
What is crude oil gravity?
Crude oil is referred to as either light, medium, or heavy, based on its density. The American Petroleum Institute gravity, commonly shortened to API gravity, compares the density of crude to water. An API gravity higher than 10 means the oil is less dense than water and will float on it. An API gravity lower than 10 means ...
Why is sulfur important in crude oil?
Sulfur content is also very important in determining the quality, and thus the price, of crude. As noted, sulfur must be removed during the refining process. High quantities of sulfur also create problems related to transporting and working with the crude.
What is the most desirable oil?
In general, light, sweet crude oil is the most desirable. However, there is one other very important factor that affects the price of crude – the location of extraction. If crude is extracted near the coast, it is much easier to transport globally.
