Reclamo De Aceite De Desperdicio

El aceite de desperdicio se origina de diferentes fuentes, tales como aceite hidráulico, aceite corriente de línea, aceite de motor, etc. Normalmente es descargado en grandes piscinas a lo largo de las áreas donde se han realizado perforaciones en el pasado. Se estima que dos millones de aves migratorias mueren cada año en piscinas de aguas de desecho de petróleo y minería en el oeste de los Estados Unidos, de acuerdo a un Agente Especial del Servicio Federal de Pesca y Vida Salvaje de los Estados Unidos de Norteamérica (FWS). La mortalidad de la vida salvaje, producto de piscinas de desechos de campos petroleros ha sido documentado por Agentes Especiales de la FWS y por Especialistas en contaminantes medio ambientales.

Multi-Media Filtration of Process Water

Allen Oil Conditioner Brochure

Lubrication and seal oil deteriorates over time due to absorption of moisture from the atmosphere, contamination of hydrocarbon gases, and acid generation as a result of hydrolysis. The Allen Oil ConditionerTM is designed to purify the compressor oil and prolong its useful life almost indefinitely.

Allen Hydroscav Oil Purifier Brochure

Hydroscav Oil Purifiers are small, compact, and lightweight. They have a minimum number of moving parts and do not require expensive, consumable spare parts.

Dissolved Gases in Transformer Insulation Fluid

Insulation fluid inside a transformer breaks down. This process generates gases inside the transformer. The types of gases can be related to the type of electrical fault; the rate at which these gases are generated is an indication of howsevere the fault is.

Astonishing Facts About Filter Elements, Part 1

The filter industry is in a state of confusion about rating their filters. Customers want a simple way to compare filter elements so the micron ratings system was invented. A micron rating is an arbitrary value assigned to a filter by the manufacturer, not an actual measured value. It quotes a particle size without establishing the filter’s efficiency at removing that size particle.

A Marine Bilge Water Treatment System

A ship’s bilge water is a mixture of discharges and leakage from a wide variety of sources, which drain to the lowest compartment (bilge) of a vessel. Bilge water includes seawater accumulation, normal water leakage from machinery, and wash downs. It can also contain a variety of constituents such as solids, cleaning agents, solvents, fuel, lubrication oil, and hydraulic oil.

A Coalescer-Separator Filter System

When two liquids are immiscible, or not soluble in each other, they can form an emulsion or a colloidal suspension. In these types of mixtures the dispersed liquid (water) forms droplets in the continuous phase (oil or fuel). For instance, in a water-diesel fuel mixture the diesel fuel is the continuous phase and the water will exist as droplets of various sizes.

Selection Parameters for Vacuum Oil Purifiers

The proper selection of a vacuum purifier for oil—whether it is for transformer oil, lubrication oil, hydraulic fluid, or thermal oil—involves the consideration of many factors. Yet strangely enough, most buyers of oil purifiers spend relatively little time on the selection process.

Maintenance of Hydraulic Oil with Best Available Technology

For a considerable time, Allen Filters, Inc. has marketed Allen Oil Conditioner as being the best available and most cost-effective technology.

Transformer Oil, Part 2: Deterioration of Mineral Transformer Oil

Moisture contamination is one of the most obvious causes of deterioration in the insulating quality of transformer oil. This contamination can be eliminated by purification.

Transformer Oil, Part 1: Maintenance of Mineral Transformer Oil

The function of transformer oil is insulation and cooling of transformers. A transformer consists of metal, oil, and cardboard insulation. The oil is actually insulating oil and is used not only in transformers, but also in circuit breakers, capacitors, bushings, and tap changers. Insulating oil is a refined mineral oil obtained from fractional distillation of crude oil. It is free of moisture, inorganic acids, alkali, sulfur, asphalt, tar, and vegetable or animal oils.

Concepts in Fluid Filtration

Filtration is the separation of a fluid-solids mixture, involving passage of most of the liquid through a porous barrier that retains most of the solids contained in the mixture.

On-Load Tap Changer Filter Systems

On-load tap changers are used for changing the transforming ratio of power transformers without supply interruption. To reduce arcing at the contacts, the tap changer operates in a chamber filled with insulating transformer oil.

Allen Tap Changer Filter Brochure

Tap changers are a vital element in regulating power flow within transformers, containing insulating oil that must be constantly maintained for maximum dielectric strength. The oil can become compromised whenever there are contaminants such as carbon, water, and metallic particles present, leading to costly repair downtime or worse, complete destruction of the transformer.

Water Activity in Oil

Oil can contain a certain amount of moisture. The maximum amount of moisture that oil can contain in solution is called its saturation point. Once the oil has reached its saturation point, any additional water that is added will separate out as free water, which then forms a distinct layer underneath the oil.

Vacuum Distillation for Industrial Oil Purification with the Best Available Technology

Can oil last indefinitely?

We do not really know how long oil can be purified and reused.

In the sixty-year history of manufacturing oil purification equipment, Allen Filters, Inc. has yet to experience a situation where, with routine and thorough purification with our equipment the oil could not be re-used for a very long time.

Sustainable Electric Power for the Emerging Markets

Lack of power impacts annual growth rates, slowing the development of new businesses and inhibiting new investment. The demand for power can lead to new investments in large-scale power projects in addition to creating markets for smaller generators of power.

A Hydroscav Reduces Waste Oil and Produces a Fast Payback

In early 1995, a new compressor for processing light hydrocarbons was brought online for the liquefaction of these products. The lube oil system was charged with expensive synthetic oil. From the first startup, it was found that the liquefied gas was leaking into the lube oil. The gas was becoming entrained in the oil diluting it, lowering its flash point and viscosity, and reducing the lubricatingcapability to unacceptable levels.

Maintenance of Phosphate Esters-Based Fluids

Phosphate esters are polar fluids with excellent lubricating properties that can operate under extreme conditions such as electro-hydraulic compounds for steam and gas turbines, aircraft carriers, as well as steel mills and foundries. However, phosphate esters require strict control in order to extend their useful lifespan.
