Some of the most important properties to consider in the processing of hydrocarbons:

Density
The density of crude oil and its fractions is expressed in terms of API gravity (° API) rather than the specific gravity. The relationship between the degree API and specific gravity is reversed, a higher specific gravity less º API, and therefore heavier crude.
Crude oil gravity ranges from values ​​lower than 10 º API to values ​​greater than 50 º API, but the most crude oils having a density between 20 and 45 degrees API.

Pickling liquor is nothing more than dilute sulfuric acid used in the iron and steel industry for removing scales on the surface of iron work which is to be further treated. The reaction for pickling may be represented by the equation FeO + H2SO4 = FeSO4 + H2O. Thus we see from this equation that H2SO4 is gradually used up and FeSO4 formed during the process. It is evident, then, after a certain length of time, H2SO4 will be too valuable to be cast away. This FeSO4 may be converted into an oxide which is a pigment, or taken out in the form of FeSO4.7H2O crystals. The latter is the purpose of this work. FeSO4 has the following uses: photography; writing ink; Prussian blue; preparation of iron oxide for illuminating gas purification; water purification; medicine; disinfectant; textile and leather industries; analytical reagent; making other iron salts.

The numerical calculation is a fundamental tool of chemical engineering as well as in many other sciences. An example is the simulation software and process optimization. When the number of variables and equations to solve is high, the limiting factor is the processing capacity. Advances in the speed of microprocessors is reaching its practical limit, and how to get more performance then is to use multiple CPU's in parallel (multi-core). Another activity that increasingly requires more processing power are the servers for computer networks in the chemical company.

In a recent seminar of Intel, called "Parallelism Programming Has Gone Mainstream: Are You Ready?" Refers to this trend and its impact on the world of software.
