Distillation process of Crude oil

Crude oil is the term for "unrefined" oil, it is also known as petroleum. Crude oil is a fossil fuel, it was made naturally from decaying plants and animals living in ancient seas millions of years ago - most places you can find crude oil were once sea beds. Crude oils vary in color, from clear to tar-black, and in viscosity, from water to almost solid. Hydrocarbons are molecules that contain hydrogen and carbon and come in various lengths and structures, from straight chains to branching chains to rings. Crude oil is refined to produce useable products such as gasoline. The process is very complex and involves both chemical reactions and physical separations. Crude oil is mixture of thousands of different molecules. It would be nearly impossible to isolate every molecule and make finished products from each molecule. Chemists and engineers deal with this problem by isolating mixtures of molecules according to the mixture's boiling point range. The problem with crude oil is that it contains hundreds of different types of hydrocarbons all mixed together. Crude Oil refinery process: The oil refining process starts with a fractional distillation column. The various components of crude oil have different sizes, weights and boiling temperatures; so, the first step is to separate these components. Because they have different boiling temperatures, they can be separated easily by a process called fractional distillation. After going through the fractional distillation, crude oil is chemically processed to change one fraction into another. Finally, Distillate and chemically processed fractions are treated to remove impurities. Fractional distillation: This process is based on the principle that different substances boil at different temperatures. For example, crude oil contains kerosene and naphtha, which are useful fractions .When you evaporate the mixture of kerosene and naphtha, and then cool it; the kerosene condenses at a higher temperature than the naphtha. As the mixture cools, the kerosene condenses first, and the naphtha condenses later.

Compressed Natural Gas and Liquefied Hydrocarbon Gases

The arrangement of normally happening hydrocarbon gases is like unrefined oils in that they contain a blend of various hydrocarbon particles relying upon their source. They can be removed as flammable gas from gas fields; oil related gas which is extricated with oil from gas and oil fields; and gas from gas condensate fields, where a portion of the fluid segments of oil change over into the vaporous state when weight is high .When the weight is diminished condensate containing heavier hydrocarbons isolates from the gas by build-up. Petroleum gas contains 90 to 99% hydrocarbons, which comprise predominately of methane together with littler measures of ethane, propane and butane. Petroleum gas additionally contains structure of nitrogen, water vapor, carbon dioxide, hydrogen sulphide and dormant gases, for example, argon or helium. Normal gases containing in excess of 50 g/m3 of hydrocarbons with particles of at least three carbon iotas are delegated lean gases.

Flammable gas from gas and gas condensate fields is prepared in the field to meet particular transportation criteria before being packed and bolstered into gas pipelines. This readiness incorporates evacuation of water with driers, oil expulsion utilizing blending channels, and the evacuation of solids by filtration. Hydrogen sulphide and carbon dioxide are additionally expelled from gaseous petrol, with the goal that they don't consume pipelines and transportation and pressure hardware. Propane, butane and pentane, display in gaseous petrol, are likewise expelled before transmission so they won't consolidate and shape fluids in the framework. Flammable gas is transported by pipeline from gas fields to liquefaction plants, where it is compacted and cooled to around – 162 °C to create melted gaseous petrol (LNG).The arrangement of LNG is not the same as petroleum gas because of the evacuation of a few polluting influences and segments amid the liquefaction procedure. LNG is fundamentally used to enlarge gaseous petrol supplies amid crest request periods and to supply gas in remote regions from real pipelines. It is degasified by adding nitrogen and air to make it practically identical to gaseous petrol before being nourished into gas supply lines. LNG is additionally utilized as an engine vehicle fuel as another option to gas.

Oil related gases and condensate gases are delegated rich gases, since they contain huge measures of ethane, propane, butane and other immersed hydrocarbons. Oil related and condensate gases are isolated and melted to deliver condensed oil gas (LPG) by pressure, adsorption, retention and cooling at oil and gas process plants. These gas plants likewise deliver regular gas and other hydrocarbon portions.

Recent Advances in Petrochemical Science

There are very limited role for thermal processing in the refinery because it does not give selective product as well as its processed stream has to pass through hydro processing. However, due to the production of heavy oil feeds using catalytic refinery process may not be efficient process. Thermal cracking processes are designed to handle heavy residues with high Asphaltenic and metal contents. Integrated Gasification Combined Cycle is one of the oldest thermal process, which is used for electricity, which can handle a wide range of poor quality feed stocks coal, heavy oil, natural gas and even plant waste and produce a wide range of products such as syngas Hydrogen, carbon dioxide, carbon monoxide . The process also crucial for hydrogen, ammonia, methanol and synthetic fossil fuel For example liquid gasoline, it contains no sulphur or benzene, making it extremely clean burning by using methanol to gasoline processes. Syn-fuels better than conventional fuel but at significantly which have higher price, Hence, syn fuels more expensive, which have wide scope for technological development in order to make production economically viable. Under gasification, the sulphur in heavy oil can be converted into carbonyl sulphide while conversion of fuel bound nitrogen to gaseous nitrogen and ammonia. Currently, process mainly used with the association of steam reforming, dry reforming and partial oxidation mainly for the coal, bottom of the barrel, asphalt or petroleum coke.

Refining Integration and Petrochemical:

The petrochemical industries and integration of refining is a mutual benefit where utilization of refinery products and by-products as a feedstock for petrochemicals. Therefore, it is a strategic benefit over reducing the costs of feed and utilizing in the form of customize products. And also both industries are looking for opportunity to make use of their processing option where refinery can process dirtier feedstock (heavy oil) while commodity supply can be improved in the petrochemical. specifically this model can be effectively utilize in the refinery for heavy oil processing mainly using cracking process or the thermal processes ,whereas petrochemical benefited from their value products such as propylene and BTX, FCC naphtha, surplus Coker naphtha, etc.

Oil Recovery Techniques - Enhanced Oil Recovery:

Enhanced Oil Recovery (EOR) is a more technologically advanced method for bringing production to surface than conventional methods of drilling. EOR is the final stage implemented in recovering all the crude oil possible from an oil reservoir. There are a number of techniques used for Enhanced Oil Recovery, each of which has variations on cost, efficiency and safety. From all these techniques, Surfactant EOR is receiving more attention in recent years.

Types of Enhanced Oil Recovery:

Oil production can be done into three phases: Primary, Secondary and Tertiary (or Enhanced Oil Recovery). Each phase requires an increasing amount of technology and energy to recover the oil. This increases the cost of well production.

Primary & Secondary Recovery

Primary recovery relies on naturally occurring pressure within the oil reservoir to drive oil to the surface. Secondary oil recovery initiates external energy to the oil reservoir when naturally occurring pressure is no longer sufficient to bring oil to the surface. It has done this by injecting water or by pumping compressed gasses into the reservoir.

The Global Need for Enhanced Oil Recovery:

As global demand for oil increases so its value and this makes more expensive oil extraction techniques more and more viable. In the long term, fossil fuels will need to be replaced by renewable energy sources. In the meantime, however, Enhanced Oil Recovery offers the only viable solution for retrieving anywhere up to 80% of the world’s oil reserves. When oil prices are low the general practice has been to extract somewhere between 20-50% of the oil through primary and secondary processes and then abandon it. Generally speaking establishing new wells has been a cheaper production method than EOR and that's why it has been slow to take off.

It is only now with improved bio-based surfactant systems that can be used at lower concentrations, the decline in new oil field discovery and rising oil prices that EOR is becoming economically viable.

Relieving the tension on global oil supply in the near and medium term is vital in securing the futures of developed and emerging economies. Whilst enhanced oil recovery is more costly, at a practical level it means the difference between expensive oil and no oil at all.

Enhanced Oil Recovery of various methods including:

Thermal EOR

Gas EOR

Chemical EOR

Hydrodynamic EOR

Combined EOR

With new advances in chemical research Chemical EOR  is fast gaining well-deserved attention as a long-term option for almost complete oil field extraction Recent developments in Chemical EOR have made even further developments making the processes safer, cleaner and more cost efficient than ever.

Advancement on Drilling Technology in Petroleum Industry

There are two drilling techniques used in the petroleum industry, the cable tool technique, and rotary drilling technique, second technique is the most common method that performs a rotary grinding action. Only these two techniques applied in the drilling phase till date. The rotary drilling technique also proved successfully, by applying laser technology in this drilling, which is a modern technology.
Cable tool drilling is the first method of these two techniques. Hole boring is achieved by repeatedly lifting and dropping a heavy string of drilling tool into the bore hole with the bit crushing the rocks into small fragments. In this method, more result was not achieved with this because it is too much time consuming, has a very less penetration rate, blowout preventers were not easily adapted and it is almost limited to drilling consolidated formations. How-ever, at the turn of the 20th century, the rotary drilling technique was introduced and it immediately replaced the cable tool method from operation. The major difference between both is that with the cable tool, drilling has to be stopped in other for cuttings to be removed from the hole, whereas with the rotary drilling technique, a mud circulates throughout the system and carries away edges from the whole whilst drilling continuously. 

Rotary technique method is most like a common hand held drill, rotating drill bit with applied force to drill down the earth crust. The prime mover, hoisting equipment, rotating equipment, circulating equipment and blowout preventers complement each other to give the rotary technique is better nowadays for drilling. These components make a complicated looking rotary drilling method is very easy method. Whereas the cable tool method; it can drill through most rock formations, has a high penetration rate and can drill deeper wells, blowout preventers are easily adapted and can drill directionally as well.

Renewable fuels and biofuels in a petroleum refinery

The bio-based crude materials and the related advancements shape an alternate and new designing test for the coordinated oil refineries. The variety of crude materials, including trace components and different strategic issues contrasted with traditional designing of fuel refineries utilizing petroleum feed stocks, needs new sorts of skills and experience.

Inexhaustible energies have been one of the latest topics so far in these present thousand years. The purpose behind the Sound judgment of process condition, product properties is expected to process fossil and bio-determined crude materials on a solitary site, the regularly expanding CO2 discharge into the environment and its effect on a worldwide temperature alteration.Another factor is political insecurity in the territories where unrefined petroleum is generated. And thirdly, financial aspects and exchange deficiencies, because of verifiably high unrefined petroleum costs, gives an extra amount to get more vitality from local sources among many of the main purchasers of oil.

Oil refinery as a stage for renewable fuels production, Petroleum refineries are common areas for inexhaustible fuels generation. They are, all things considered, worked for the creation of cutting edge powers by the most financially intends to convey fitting items for encompassing social orders. Refineries are exceptionally experienced with their crude materials and gear, the least difficult and least expensive approach to process inexhaustible fuel in a current refinery. Regularly, the refineries additionally have broad information of product and fuel markets, yet for oil based powers as it were. The handling of bio feed stocks implies entering an unknown territory.
