Very often, fractional distillation of crude oil produces more of the larger hydrocarbons than can be sold, and less of the smaller hydrocarbons than customers want. Smaller hydrocarbons are more useful as fuels than larger hydrocarbons. Since cracking converts larger hydrocarbons into smaller hydrocarbons,

Thermal cracking is a process in which hydrocarbons present in crude oil are subject to high heat and temperature to break the molecular bonds and several advantages over conventional pyrolysis methods that include uniform internal heating of large The effectiveness and limitations of twisted slices was illustrated.

Of course, petroleum has both advantages and disadvantages that we should be aware of. Details about these are helpful to determine its proper and practical use. They also serve as guide for us especially those who are using it often for a variety of purposes. Advantages and Disadvantages of Using Oil Energy. Oil is one of the most crucial commodities in the world that you cannot live without. This is because it is used in almost all industries that require energy input such as motor vehicle industry, power generation, and other numerous sectors. Oil is transported in crude form. This makes water Very often, fractional distillation of crude oil produces more of the larger hydrocarbons than can be sold, and less of the smaller hydrocarbons than customers want. Smaller hydrocarbons are more useful as fuels than larger hydrocarbons. Since cracking converts larger hydrocarbons into smaller hydrocarbons, The advantages of catalytic cracking over thermal cracking are as follows . Catalytic cracking takes place at lower temperature and pressure (3000C -400 0 C and 1-5kg/cm 2) as compared to that of thermal cracking (500 0 C-600 0 C and kg/cm 2); Catalytic cracking yields a higher quantity of branched-chain, unsaturated, aromatic hydrocarbons as compared to thermal cracking. Originally Answered: What is the disadvantage of crude oil? Compared to other energy sources it often involves a concentrated revenue going to whoever claims to be the government of the country, and the revenue then props up the government and allows corruption etc to sink in, avoiding normal democratic processes Biggest Disadvantages of Fracking 1. It encourages us to use fuels that are finite. Fracking gives us access to natural gas and crude oil deposits. These may fuel economies and help us in numerous ways, but they are also fuel resources that are finite. Some disadvantages of oil are that - * it is non-renewable and fast depleting; * burning it releases carbon dioxide, a powerful greenhouse gas, that had been stored in the earth for millions of years * it leaves behind harmful by-products upon combustion,

10 Dec 2016 The aim of this study is to present the advantages and disadvantages of shales gas After sharp increases in oil and natural gas prices, shale gas became of earthquake: Drilling the shale gas is made by hydrolic cracking.

Disadvantages - Most of the resource is uneconomic at present oil prices - so exploitable reserves are less than for crude oil - Oil sands require mining, which is more complex and costly than drilling and pumping crude oil. - Processing requires more energy than for crude oil.
