Diesel is a popular fuel choice and more and more people have moved over to diesel from petrol as the vehicles often get further on a tank of fuel when you compare it to petrol vehicles. This has made it a popular choice for those businesses that run fleets of vehicles and that use the services of BP Fuel Cards like the ones from www.fuelcardservices.com/fuel-cards/bp-fuel-cards/. These cards allow the employees to fill up their work vehicles and to have the payments taken out of the fuel cards rather than from their own money, which they would then need to put an expenses claim into the business, to get the money back.

But where does Diesel actually come from?

It is actually a product of crude oil that is mined across the world. The oil is taken through a process known as fractional distillation that occurs in a fractioning column. The crude oil is heated up to temperatures of 400 degrees celsius. It is at these high temperatures that the crude oil begins to separate into hydrocarbons – one of which is diesel. The hydrocarbons that heat up at lower temperatures leave the fractioning column first. Diesel leaves the column when the oil has reached a temperature of around 300 degrees celsius.

The crude oil used in the fractioning of diesel comes from deep within the earth and is found by drilling large holes into the ground. The exact location of the oil is researched before the holes are created. This is often done by using seismic waves.
