Crude oil is the origin for most liquid and gas hydrocarbon products. The variety of products derived from crude oil is immense, although the basic fuels we use for transportation (gasoline, diesel, jet fuel, etc) amount for the use of 80% of a barrel of crude oil. Another very important product from crude oil is lubricants for combustion motors and other kinds of machinery. Crude oil in its natural form comes mixed with many undesired solid contaminants, which must be removed during the refining processes. Several kinds of filtration systems can be applied in different stages of the purification processes of crude oil, depending on the use that wants to be given to the product being filtered.
Complete Systems for Oil Filtration
The most common technology in the first stages of oil filtration is the strainer, to remove coarse contaminants. These can be temporary (put inside a section of the pipeline when the operation of the plant is scheduled to start, in order to remove contaminants present in the new pipelines): temporary strainers (cone shaped) will be removed later, when the operation of the plant become stable. However, more commonly strainers are installed permanently on the pipeline. Permanent strainers can be “Y” type (with very small capacity to collect contaminants), or basket strainers (larger contaminant loading capacity). They can be designed and installed in simplex or duplex (side by side) arrangements. Although the body of the permanent strainer can be different metals (iron, carbon or stainless steel), the straining element is usually stainless steel. Beyond the process of crude oil refining, many industrial applications also require oil filtration: fluids used for cooling, lubricating, and hydraulics also need complete filtration systems.
Solutions for Fine Oil Filtration
In the latter stages of oil (and other industrial fluids), finer filtration technologies must be considered. Since now the need is to bring the product to more strict levels of cleanliness by removing smaller particles, finer media filter solutions must be considered. We can propose filtration systems with different types of filter elements: cartridge or bag shaped. Technologies available include surface or depth type filters; flat or pleated. We can handle the most demanding applications, so a wide variety of materials is available for the filtration media: from cellulose, polypropylene, cotton, and nylon, to longer lasting materials: stainless steel y very fine mesh, or sintered. The purpose is to filter the fluids to the necessary level of purity, in an efficient yet economical way.
