Fractional distillation of crude oil essay

On an industrial level, fractional distillation is expensive because it requires large structures, heavy-duty materials, and specialized machinery. Some mixtures form azeotropeswhere the mixture boils at a lower temperature than either component. The distillation towers have liquid outlets at intervals up the column which allow for the withdrawal of different fractions or products having different boiling points or boiling ranges.

It was soon discovered that high quality lubricating oils could be produced by distilling petroleum under vacuum. As the vapor rises through the trays in the column, it cools. The hottest tray is at the bottom and the coolest is at the top.

In the quality planning process, the analysis can be used to optimize process features and goals and to design for critical factors and human error. Most of our modern lifestyle depends on oil. What actions resulted in these faults being created? List of Disadvantages of Fractional Distillation 1.

According to the Encyclopedia of The Earth, even though these are closed processes, heaters and exchangers in the atmospheric and vacuum distillation units could provide a source of ignition, and the potential for a fire exists should a leak or release occur. The mixture of vapours that enters the fractional distillation tower starts to condense as the temperature cools the higher the gases go.

There are some sections of the process that could easily be affected to corrosion include, preheat exchanger, preheat furnace and bottoms exchanger, atmospheric tower and vacuum furnace, vacuum tower and overhead. Petroleum gas Used for heating, cooking and making plastics. This process of breaking down the event to identify contributory causes and their interaction continues until the root causes are identified.

This in turn may result in the assumption that the danger has cleared. The trays have many holes or bubble caps like a loosened cap on a soda bottle in them to allow the vapor to pass through.

The Graham condenser is a spiral tube within a water jacket, and the Allihn condenser has a series of large and small constrictions on the inside tube, each increasing the surface area upon which the vapor constituents may condense.

Order now The purpose of this report is to study a case scenario involving the fractional distillation process and its potential hazards and risks.Fractional Distillation of Crude Oil Essay Crude oil is a naturally occurring, unrefined petroleum product composed of hydrocarbon deposits.

6 Advantages and Disadvantages of Fractional Distillation

It is a fossil fuel, meaning that it was made naturally from decaying plants and animals. 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.

Fractional Distillation of Crude Oil

As every hydrocarbon in petroleum has it a particular boiling point, by doing so, they will separate out and then be collected. 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. The steps of fractional. Crude oil is separated into fractions by fractional distillation.

The fractions at the top of the fractionating column have lower boiling points than the fractions at the bottom.

Factional Distillation of Crude Oil

All of the fractions are processed further in other refining units. The purpose of this report is to study a case scenario involving the fractional distillation process and its potential hazards and risks.

INTRODUCTION Inthe petroleum industry began with the successful drilling of the first commercial oil well and the opening of the first refinery to process the crude into kerosene. This process is called fractional distillation. 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.
