Petroleumrefining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.[1][2][3]

Refineries and petroleum industries are very large industrial complexes that involve many different processing units and auxiliary facilities such as utility units and storage tanks. Each refinery has its own unique arrangement and combination of refining processes largely determined by the refinery location, desired products and economic considerations.

Prior to the nineteenth century, petroleum was known and utilized in various fashions in Babylon, Egypt, China, Philippines, Rome and along the Caspian Sea. The modern history of the petroleum industry is said to have begun in 1846 when Abraham Gessner of Nova Scotia, Canada devised a process to produce kerosene from coal. Shortly thereafter, in 1854, Ignacy Lukasiewicz began producing kerosene from hand-dug oil wells near the town of Krosno, Poland. The first large petroleum refinery was built in Ploesti, Romania in 1856 using the abundant oil available in Romania.[7][8]

In North America, the first oil well was drilled in 1858 by James Miller Williams in Ontario, Canada. In the United States, the petroleum industry began in 1859 when Edwin Drake found oil near Titusville, Pennsylvania.[9] The industry grew slowly in the 1800s, primarily producing kerosene for oil lamps. In the early twentieth century, the introduction of the internal combustion engine and its use in automobiles created a market for gasoline that was the impetus for fairly rapid growth of the petroleum industry. The early finds of petroleum like those in Ontario and Pennsylvania were soon outstripped by large oil "booms" in Oklahoma, Texas and California.[10]

Prior to World War II in the early 1940s, most petroleum refineries in the United States consisted simply of crude oil distillation units (often referred to as atmospheric crude oil distillation units). Some refineries also had vacuum distillation units as well as thermal cracking units such as visbreakers (viscosity breakers, units to lower the viscosity of the oil). All of the many other refining processes discussed below were developed during the war or within a few years after the war. They became commercially available within 5 to 10 years after the war ended and the worldwide petroleum industry experienced very rapid growth. The driving force for that growth in technology and in the number and size of refineries worldwide was the growing demand for automotive gasoline and aircraft fuel.

In the United States, for various complex economic and political reasons, the construction of new refineries came to a virtual stop in about the 1980s. However, many of the existing refineries in the United States have revamped many of their units and/or, constructed add-on units in order to: increase their crude oil processing capacity, increase the octane rating of their product gasoline, lower the sulfur content of their diesel fuel and home heating fuels to comply with environmental regulations and comply with environmental air pollution and water pollution requirements.

The crude oil distillation unit (CDU) is the first processing unit in virtually all petroleum refineries. The CDU distills the incoming crude oil into various fractions of different boiling ranges, each of which are then processed further in the other refinery processing units. The CDU is often referred to as the atmospheric distillation unit because it operates at slightly above atmospheric pressure.[1][2][14]

Below is a schematic flow diagram of a typical crude oil distillation unit. The incoming crude oil is preheated by exchanging heat with some of the hot, distilled fractions and other streams. It is then desalted to remove inorganic salts (primarily sodium chloride).

Following the desalter, the crude oil is further heated by exchanging heat with some of the hot, distilled fractions and other streams. It is then heated in a fuel-fired furnace (fired heater) to a temperature of about 398 C and routed into the bottom of the distillation unit.

The cooling and condensing of the distillation tower overhead is provided partially by exchanging heat with the incoming crude oil and partially by either an air-cooled or water-cooled condenser. Additional heat is removed from the distillation column by a pumparound system as shown in the diagram below.

As shown in the flow diagram, the overhead distillate fraction from the distillation column is naphtha. The fractions removed from the side of the distillation column at various points between the column top and bottom are called sidecuts. Each of the sidecuts (i.e., the kerosene, light gas oil and heavy gas oil) is cooled by exchanging heat with the incoming crude oil. All of the fractions (i.e., the overhead naphtha, the sidecuts and the bottom residue) are sent to intermediate storage tanks before being processed further.

The image below is a schematic flow diagram of a typical petroleum refinery that depicts the various refining processes and the flow of intermediate product streams that occurs between the inlet crude oil feedstock and the final end-products.

The diagram depicts only one of the literally hundreds of different oil refinery configurations. The diagram also does not include any of the usual refinery facilities providing utilities such as steam, cooling water, and electric power as well as storage tanks for crude oil feedstock and for intermediate products and end products.[1][2][15]

People who work oil refinery jobs play an essential role in our economy. They support the oil and gas sector of the energy industry, which most people depend on to fuel their cars, heat their homes and cook their food. A refinery engineer is a specific branch of engineering. It overlaps with other areas of the field, such as mechanical engineering, chemistry, physics and geology.

The first step to becoming a refinery engineer is to earn a bachelor's degree from an accredited college or university. You can major in engineering, but the writers at BestAccreditedColleges explain that earning your degree in a more specific field, such as mechanical or chemical engineering, can help. Some schools even have programs in petroleum engineering.

Take classes in related fields, especially the natural sciences and mathematics. In addition, try to obtain internships or summer jobs in the field in some capacity. Most refinery engineers work for major energy companies, so those are great places to seek internships. However, getting experience working with the federal government or its contractors is also smart.

Most refinery engineers do not pursue education past their bachelor's degrees, but that doesn't mean their training is over. They still need to earn their initial and full licenses, a time-consuming process requiring years of experience.

Each state sets its own licensure standards, but most requirements are similar. Most states in America have two levels of licensing for refinery engineers. The first requires a bachelor's degree, and in some states, you also have to pass an exam. At that point, you can begin working in the field.

You qualify for the next stage of licensing after you gain some experience. Most states require four years of work in the field, but check to be sure. In some places, you can substitute further education for work experience, but you may be at a disadvantage when you enter the job market.

Before you earn full licensure, you will be under the supervision of a fully certified refinery engineer. Either your employer or the state will pair you. You'll need to complete continuing education requirements to renew your license periodically once you're fully certified. You'll also want to join the Society of Petroleum Engineers, which can issue certifications and host opportunities for continuing education.

Of course, salaries vary depending on the company, where you work and other factors. However, a Marathon petroleum refining engineer salary will be similar to that of other companies for a comparable position and qualifications.

The job outlook for refining engineers is at a growth rate of about 8 percent, which is faster than the national average, despite the fact that petroleum industries have come under criticism for their detrimental impact on the environment. Still, the American economy is dependent on fossil fuels, and that fact is unlikely to change in the near future.

What does petroleum refining refer to? Petroleum refining refers to all those chemical engineering processes that are undertaken in refineries to convert crude oil to various finished products. Refineries are generally large industrial complexes with multiple units and facilities.

Each refinery has its unique layout and facilities depending on refinery location, desired products, etc. The petroleum refining process broadly consists of three processes, namely separation, conversion and treatment.

Production planning involves breaking down these processes into individual operations and determining and defining a standard sequence of events that would deliver a finished product. Scheduling involves factoring of time and due dates to add chronological order to the plan for specificity. Through planning and scheduling, the optimal yield is obtained from refineries.
