the viscous fluid that comes out of the ground is unprocessed hydrocarbons which are called crude oil.
crude oil is a fossil fuel which is made up of decaying plants and animals inhabiting the oceans.
In the first process, they distill crude oil by parts and in a physical form that each of these parts has a different boiling point .
This operation take place in distillation or separation towers, which it produces various items such as: oil, diesel and etc.
Bitumen is one of the important petroleum products which is made up by crude oil. Bitumen production is take place according to continuous and discontinuous process.
Of course, you should note that in addition to the production, the Bitumen maintenance method is also very important.
Bitumen maintenance
You should take care of Bitumen at very low temperature. For example:
The safe temperature of Bitumen for specific operations is 2005 institute.
And for normal tasks, You need to consider temperatures 10 to 50 degrees Celsius higher than the pumping temperature.
The safe temperature of control for Bitumen storage is 230 degrees Celsius ,and this temperature should not exceed.
But if you want to keep Bitumen without added material for a long time, For example more than a week, temperature should decrease between 20-25 degrees Celsius above the softening point of Bitumen.
And if it’s possible,stop the circulation .
When they store Bitumen in storage, they have to it intermittently. especially when they use of a direct flame to heat the Bitumen and the temperature may reach over 300 degrees Celsius.
When you soften the Bitumen , the temperature can be higher than 300 degrees.
Because Bitumen is a viscous liquid that the circulation of heat convection spreads throughout it.
And other high heat doesn’t cause any problems for Bitumen.
If you carry Bitumen correctly, you can heat it for a considerable period of time or keep at high temperatures without negative effects on the characteristics of Bitumen.
Types of Bitumen
Based on Bitumen’s production origin, It has been placed under processes and divided into different types, we mention two of them:
