Most oil wells are drilled with rotary method. In this method, a tower holds the drill string, consisting of a series of tubes attached.
The chain linking it to the bank spins rotating in the floor of the tower. The drill bit at the end of the chain usually consists of three bevel gears with hardened steel teeth. The drill is brought to the surface by a continuous circulating fluid system driven by a pump.

The activity of oil companies in Ogoniland area in southern Nigeria, has left a high level of pollution in the area that might not be removed 20 to 30 years, according to a report released today by the United Nations Program Environment Programme (UNEP).
The UN study, requested by the Government of Nigeria and funded by the Shell oil company, is the result of 14 months of analysis of the environmental situation in the area after fifty years of exploitation of its oil fields.

A common mistake in designing compressed air systems, is to design very small lines for the desired air flow. This is not limited to the head pipe of the compressor suction and discharge the same. Also applies to the distribution lines of compressed air production areas.
Subdimensions pipe restricts flow and reduces the discharge pressure, consequently resulting in excessive energy use in the compressor.

Desulphuring plants are designed to process different types of cargo, ranging from light naphtha to gas oil mixture and lubricating oils.
The following describes the two stages of the process in general.
Response Section.
This section is the same for all types of cargo to be processed. The charge is pumped warm equipment, after being mixed with the hydrogen recirculation of process and the replacement of a plant usually from Reformer.

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.

The design process is one of the most exciting and complex fields within chemical engineering, and is the heart of the development of engineering projects related to building new processing plants.
The design of a process is an interdisciplinary task that encompasses all fields of engineering and has been divided into three main stages:

The chemical engineering is one of the most challenging and rewarding careers you can choose.
This is because the chemical industry is one of the most important driving forces of the economies of many countries, serving as a basis for other industries such as steel, petroleum, food and electronics.

Any process that must be monitored sensors required to know the variables of a process in real time. If required to monitor a large number of process variables in the same proportion will require a large number of sensors for these variables. The sensors are expensive, require maintenance and may be calibrated to be very sensitive, plus they need a "hardware" that connect to the monitoring unit. Would not it be better if you could spare some few sensors and still be able to monitor the entire process?
This is the aim of so-called "virtual sensors" or "Software Sensors", better known in the control engineering as "observers" or "state estimator". Observers are computer programs from the measurements obtained by a number of real sensors, to estimate the process variables that does not have its respective sensor. The program reproduces the observed system giving you the information of what the stimuli (inputs) that receives the actual process. A second source of useful information for the observer is the data received from the monitoring system performance (outputs).
