Refinery treatment processes

Crude oil and its cuts are mainly composed of hydrocarbons. Refinery treatment processes are

separation and transformation techniques enabling to extract its different fractions and to produce

several products ,from gases to asphalts and coke. Depending on the crude oil source,

the cuts have not the same quality and quantity. An industrial unit designed for crude

distillation is generally calculated and dimensioned for a defined feeding crude oil.

In fact, all new oils have to be analysed and characterized (number and quality of cuts mainly)

so that mixtures are prepared to feed the industrial unit with the characteristics needed.

Therefore, by mixing different oils, it is possible to feed the refinery with an almost

constant composition mixture and have only one industrial unit to process all crude oils.

The ASTM standard proposes a procedure to characterize crude oil. This standard enables

to compare the obtained results wherever the analysis is done.

Distillation or rectification

The distillation process separates several volatile liquids, simple or complex mixtures,

by a series of vaporisation and condensation steps.

A number of liquids may be separated in this way if their boiling points are sufficiently different.

Continuous distillation separates a mixture into fractions: a volatile fraction, the distillate extracted

at the column head and a heavy fraction, the residue extracted at the bottom of the column.

Distillation

Distillation is a process including heat and material transfers in order

to separate one or several products of relative different volatility.

The separation is carried out by a chaining of vaporizations and condensations.

The theoretical base is that a vapor produced from a mixture is in equilibrium with

the mixture liquid phase and has generally a higher composition in the most volatile compound.

The separation is carried out in a column (packed or plates column) designed to get the best

contact and material exchanges between the climbing vapor and the falling liquid into the column.

This separations can be done in continuous or discontinuous (batch) process.
