Necessity of use:

... During the drilling, repairing, acidizing and testing of oil wells, usually a large amount of oil is accumulated in a pit in the ground and burned. This has several economic and environmental impacts including air and soil pollution and waste of energy and financial resources.

Crude oil is a mixture of many different kinds of organic compounds, many of which are highly toxic and cancer causing. Oil spills can have disastrous consequences for society; both economically, environmentally, and socially. As a result of these consequences oil spill accidents can initiate intense media attention and political uproar.

Oil spills penetrates into the structure of the soil and can have significant deleterious consequences for ecosystems. There are radical soil chemistry changes which can arise from the presence of many hazardous chemicals even at low concentration of the contaminant species. These changes can manifest in the alteration of metabolism of endemic microorganisms and arthropods resident in a given soil environment. The result can be virtual eradication of some of the primary food chain, which in turn could have major consequences for predator or consumer species.

Contaminated or polluted soil directly affects human health through direct contact with soil or via inhalation of soil contaminants which have vaporized; potentially greater threats are posed by the infiltration of soil contamination into groundwater aquifers used for human consumption, sometimes in areas apparently far removed from any apparent source of above ground contamination.

When oil or petroleum distillates are burned (see combustion), usually the combustion is not complete. This means that incompletely burned compounds are created in addition to just water and carbon dioxide. The other compounds are often toxic to life. They also could lead to acid rains and climate changes.

Mobile Oil Treater (MOT)

... Mobile Oil Treater (MOT) is a device for eliminating acid, gas, water, salt, sand and silt from crude oil and pumping it to the pipeline during the drilling, repairing, acidizing and testing of oil wells. This device also could be utilized for different oil wells with different oil properties. As emphasized in its name, this device is mobile and it is possible to utilize it on any needed oil well and then easily transfer and install it on another one. It is composed of seven trailers. This units are:

Trailer No.1: Process Equipment Unit

... Separation of solid, sand particle, silt and three phase of vapor, oil and water is done in the first trailer. This installation contains of following main components:

Trailer No.2: Process Equipment Unit

... Treated oil from Desalter and other units are sent to second trailer to the Surge Drum to store and then pump to production plant. This installation contains of following components:

Trailer No.3: Utility Unit

...

Utility trailer is used to provide power, energy and all MOT device requirements such as:

Trailer No.4: Desalter Unit

... ...

After the separation of sediment particles from oil flow, it conducted to desalter in order to separate salty water as emulsion in oil. This water normally contains dissolved salts, principally chlorides of sodium, calcium, and magnesium. Desalting can be performed in a single stage, with high efficiency.

Trailer No.5: Injection package

...

Injection package consist of four injection materials which are designed for doing specific action. Each one is described below:

Each injection package consist of storage tank and two injection pumps.

Trailer No.6: Porta cabin

This cabin includes kitchen, welfare services, wash hand basin and W.C & bathroom.

Trailer No.7: Control Cabin Unit

...

A control package is installed on a unit as control room for systematic control of oil treatment operation. All instrument equipment in units are connected to control system via connecting cables. The control system which is used in MOT process consist of three mail station:
