Petroleum byproducts are secondary products that are derived during the refining process of crude oil. Crude oil, when extracted from the earth, is a complex mixture of hydrocarbons and other compounds. In order to obtain useful products such as gasoline, diesel, kerosene, and others, crude oil is refined through a series of processes. During this refining, several byproducts are produced which have their own set of applications. Some common petroleum byproducts include: **Asphalt**: Used for paving roads and roofing materials. **Paraffin Wax**: Used in candles, packaging, and cosmetics. **Lubricating Oils**: Used in machinery and engines. **Naphtha**: A volatile flammable liquid hydrocarbon mixture which can be used as a solvent or in making some chemicals. **Tar**: Used for road construction and roofing. **Petroleum Coke**: Used in the production of electrodes for the steel and aluminum industries. **Sulfur**: Extracted during the refining process and used in the production of sulfuric acid, fertilizers, and other chemicals. **Petrochemicals**: These are chemicals derived from petroleum and are used as raw materials in a wide range of products such as plastics, synthetic rubber, dyes, resins, and more.
Petroleum engineering is the engineering specialty that is focused on locating and extracting sources of petroleum. These engineers often work with specialists such as geologists and hydrologists to determine the best, most cost effective method to remove petroleum sources from the earth. The chief responsibility of a petroleum engineer is to select and supervise the method by which petroleum sources are to be extracted. However, the job is not nearly that simple, there are several factors that impact the engineer’s decisions. The first factor that petroleum engineers consider when drilling is the depth at which the reservoir is located as different drilling methods are to be used at varying depths. From there, the engineer must test the reservoir to determine its size and level of connectivity. In some cases it is possible to remove petroleum from multiple reservoirs through complex drilling and a process known as fracturing. The last, and often most important, decision made by a petroleum engineers involves the pressure and other environmental factors that allow petroleum to naturally flow to the surface of a well. Petroleum engineers have employed a variety of methods to remove as much petroleum as possible from a well; examples would be injecting steam and water into the reservoir. The minimum requirements to become a Petroleum Engineer are to earn a bachelor’s degree in petroleum engineering; however, it is very possible to cross over from another engineering specialty such as chemical or mechanical engineering. It is a very good idea for students interested in petroleum engineering to secure an internship during college to gain highly valuable work experience. Graduate degrees are necessary for many research and development positions. The employment opportunities in petroleum engineering are expected to be very good. There is to be an 18% growth over the next decade according to www.bls.gov ; in addition, there are too few graduates with degrees in petroleum engineering to fill the positions. Petroleum engineers are the most highly paid of the engineering specialties; starting salaries for a petroleum engineer are typically around $83,000, one of the highest for any bachelor’s level program. On average, workers in the field earn from $100,000 to $110,000.
Petroleum distillates are products made from crude oil. The process of taking crude oil and creating finished products is called distillation. The first step of the refining process is running crude oil through a distillation tower. At this time crude oil is separated into different basic products which then undergo further process at the refinery to create products that are sold to consumers. There are three classes of distillate products: Light: Liquid Petroleum Gas(LPG), gasoline, and naptha. Medium: Kerosene (and jet fuel) and diesel. Heavy/Residuum: Heavy fuel/bunker fuel, wax, and asphalt.
Reforming of petroleum is a chemical process used to convert low-quality hydrocarbons into higher-quality fuels and chemical feedstocks. This process typically involves the rearrangement of molecular structures through methods such as catalytic reforming, which improves the octane rating of gasoline. Reforming helps produce essential components for gasoline and other products while maximizing the efficiency of crude oil utilization. Additionally, it contributes to reducing harmful emissions by enhancing fuel quality.
Gasoline in a fractional tower is used for the separation of different hydrocarbon components from crude oil through a process called fractional distillation. As crude oil is heated, various fractions vaporize at different temperatures and rise through the tower, where they condense at different levels based on their boiling points. The lighter fractions, including gasoline, are collected at the top, while heavier components are drawn off at lower levels. This process allows for the efficient extraction of gasoline and other valuable petroleum products.

You should replace your CPO (Chemical Protective Outerwear) if it becomes wet through the inner lining due to exposure to petroleum oil or hydraulic fluid, as these substances can compromise the protective qualities of the garment. Even if the outer layer appears intact, the integrity of the inner lining may be compromised, reducing its effectiveness against hazardous materials. It's crucial to prioritize safety and ensure that your protective gear provides the necessary barrier against contaminants. Regular inspection and timely replacement are essential for maintaining optimal protection.
