An ultrasonic degreaser uses energy emitted from a transducer to break up grease and other contaminants on a part.An ultrasonic degreaser is often incorporated into vapor degreasers in industrial degreasing.An ultrasonic degreaser is effective in cleaning parts difficult to degrease using other methods C.J. Beathard Jersey , it is now used widely for certain applications ranging from cleaning a glass lens to degreasing automobile parts. Porous materials such as brass are especially difficult to clean using conventional metal degreasers.Many ultrasonic degreasers are integrated into a solvent cleaning process, components such as filters, rinsers, dryers and other design-specific features are included in the ultrasonic degreaser. Components will vary depending upon the use requirements of the degreaser. Industrial models may be quite large and have multiple chambers while tabletop models for personal use are easily portable.The combination of mechanical cleaning through cavitation and chemical cleaning from the vaporized solvent generally results in a highly satisfactory degreasing.There are two methods that are combined in ultrasonic degreasers: ultrasonic cleaning and vapor degreasing. Ultrasonic degreasers are composed of metal tanks equipped with heating elements in the bottom of the tanks that heat special cleaning solvents to a boil in a closed vessel. As the solvent evaporates it rises to a chamber where the part is placed. Because of the difference in temperature Ahkello Witherspoon Jersey , the solvent condenses onto the part, dissolves the stain and drips off of the part.

Ultrasound may be used alone for parts potentially harmed by immersion in water. The recognition of harmful impact on the environment of solvents classified as ozone depleting solvents (ODS), industrial degreasing machines have been designed to work with a solvent type that is more environmentally friendly. The ultrasonic degreasers are the last type of solvent degreaser that can be used. This type of unit is similar to the vapor degreasers but it uses ultrasonic waves to clean the parts. The parts that need to be degreased are placed into the tank, and then are sealed off. The ultrasonic components are then turned on for the desired amount of time.Though tightly bonded soils Solomon Thomas Jersey , greases, and contaminants cannot always be removed with the use of ultrasonic degreasers alone, combining traditional cleaning techniques with ultrasonic cleaning technology has been found to be an effective and environmentally-safe method of cleaning. Ultrasonic degreasers are capable of cleaning individual parts as well as multiple items simultaneously and are used in a variety of commercial and industrial applications in the fabrication, metal processing Richard Sherman 49ers Jersey , automotive, pharmaceutical, electronics and weapons industries.It is ideal for use with traditional solvents like trichloroethylene and methylene chloride, as well as many of the newer solvent. An ultrasonic vapor degreaser has two solvent-filled sumps (the boil sump and the cold sump which is filled with clean Jerry Rice 49ers Jersey , distilled condensate solvent and is often used for rinsing). Near the top of the degreaser is a set of cooling coils that catches the vapor before it escapes from the unit. It cools and condenses it back to its liquid form and flows it back to a clean condensate tank and finally it goes back to the boil sump or the rinse tank.

ACCRA, June 27 (Xinhua) -- A raging storm is brewing over alleged sale of contaminated petroleum products by Ghana's state owned Bulk Oil Storage Company (BOST) to consumers.

BOST is accused of selling some five million liters of off-spec petroleum product -- product that does not meet national standards -- to a company called Movenpiina.

According to investigations by African Center for Energy Policy (ACEP), the product got contaminated through an accidental blend of petrol and diesel which occurred when a petrol flow-line was misdirected into a diesel tank during a discharge of petrol cargo into the Accra plains depot of the state-run institutions which store strategic fuel reserves for use in times of need.

Following the revelation by civil society group, Public Eye in Switzerland that Ghana had been the dumping ground for dirty fuel for some time Joe Montana 49ers Jersey , ACEP and other stakeholders have worked with the government to arrive at a consensus to change the regulated sulfur content from the current 3000ppm to 50ppm, effective from 1st July, 2017.

Industry watchers express worry that instead of refining the product to purify it, BOST allegedly sold it to a company which was yet to be registered.

Both the parliamentary minority and the pro-government ACEP are calling for investigations into the deal.

"The norm and practice is that Jimmy Garoppolo 49ers Jersey , when such contaminations occur, corrective treatment of these products are undertaken by the Tema Oil Refinery through blending. Why did BOST not arrange with TOR for the treatment of this particular fuel? Available information indicates that BOST failed to exhaust all means to ensure TOR blends this contaminated fuel," Emmanuel Amarh-Kofi Buah, Minority Spokesperson on Mines and Energy Reuben Foster 49ers Jersey , told the press here on Tuesday.

He described as untenable the excuse by BOST that the contaminated products were sold for use by manufacturing companies.

The Minority among other demands called for full scale investigation by the regulatory authorities, the National Petroleum Authority (NPA), and the immediate withdrawal of the contaminated product from the market to protect consumers with assurances to prevent such occurrences.

They also urged that the financial loss estimated at 14.25 million Ghana cedis (3.2 million U.S. dollars) be retrieved by surcharging the offending officials at BOST in line with the recent Supreme Court decision.

On their part, ACEP deplored the situation Richard Sherman Elite Jersey , describing it as a drawback on the quest to sanitize the petroleum marketing space to protect consume.
