Based on the case study stated previously, a risk scenario involving petroleum refining processes will be developed in case of emergency situation during which time a certain procedure need to be followed to prevent any accident from happening.
Useful in investigating accidents or problems resulting from use of a complex system. The process of fractional distillation is used to separate these different ingredients of petroleum crude during the manufacture of petrol and other fuels derived from petroleum crude.
The petrol crude is a mixture of many different types of hydrocarbons mixed together. A liquid boils when its vapor pressure is equal to the atmospheric pressure. Refining is the processing of one complex mixture of hydrocarbons into a number of other complex mixtures of hydrocarbons. If not, ammonia chloride will be deposited which could cause severe corrosion.
When the metal temperatures exceed ? As a conclusion the chemical hazards could occur due to ignition or fire that is produce from a leakage or cracks inside the distillation units.
We cannot predict their physical behavior that can influence the properties of a gas leak. This is a consequence of the increased kinetic energy needed to break the intermolecular bonds so that individual molecules may escape the liquid as gases. Besides that, reducing the potential severity of the impacts of a chemical release through mitigation measures containment dikes, sprinkler systems or emergency response plans should be carried out.
Cracking is a good and important source of alkenes as it consistently produces both alkenes and alkanes, for example propane. This will be placed at the top of the tree, in its own individual box. Crude oil is also a naturally occurring hydrocarbon. Exposes the needs for control or protective actions to diminish the risk.
This is one of the solutions to reduce the chemical hazards.
Naphtha or Ligroin Intermediate that will be further processed to make gasoline. By using alkaline chemicals, the corrosion process of the distillation unit wall could be controlled thus reduce the number of accidents.
Kier was the first person to refine crude oil and he used the flammable oil produced by his salt wells to light his salt works at night. The sections of the process that might be exposed to corrosion include, preheat exchanger, preheat furnace and bottom exchanger, atmospheric tower and vacuum furnace, vacuum tower, and overhead.
Elimination of the hazards: Catalytic cracking utilizes a catalyst along with a lower temperature. Fault trees may become very large and complex. A risk scenario is an important concept before conducting a risk assessment. Hence, we can find the solution for these problems if an accident occurs.
Safety and health at the workplace is the responsibility of both employers and employees. You basically heat crude oil up, let it vaporize and then condense the vapour The various components of crude oil have different sizes, weights and boiling temperatures; so, the first step is to separate these components.
Accidents are an inevitable part of a job.8. 2. 1 (iv) Fractional Distillation of Crude Oil By Blake Turner – Year 11 Fractional Distillation of Crude Oil Introduction Crude oil is the term for “unprocessed” oil, the stuff that comes out of the ground.
It is also known as petroleum. Fractional distillation or petroleum refining is the process of separating crude oil into different components based on their hydrocarbon chains.
It is one of the most important major processes in. Overview Of Fractional Distillation Environmental Sciences Essay. Print Reference this. Published: 23rd March, Disclaimer: This essay has been submitted by a student.
This is not an example of the work written by our professional essay writers. Kerosene is obtained from the fractional distillation of petroleum at Â°C and Â.
The specific method for this separation in crude oil is known as fractional distillation. Fractional distillation is carried out by heating the petroleum to °C.
As every hydrocarbon in petroleum has it a particular boiling point, by doing so, they will separate out and then be collected.

Petroleum contains many alkanes and alkenes and has several impurities when removed from underneath the earth. Refining petroleum entails both the removal of these impurities and also the separation of petroleum into its various components.
The specific method for this separation in crude oil is known as fractional distillation.Download
