Abstract: A degassing and water removal apparatus is used in combination with the testing or replacement of dielectric oil in an RF transmitter. The apparatus comprises at least one ultrasound transducer in vibrational communication with a bulk oil sample held in a tank having a reduced internal air pressure. The tank has fluid connections to the RF transmitter through which oil from the transmitter is drained to the tank and through which the ambient air pressure in the transmitter is reduced. A fluid pump is used to pump the oil from the tank back to the RF transmitter. In a method of using such an apparatus, the RF transmitter is held at reduced internal pressure during the return of oil thereto, so that the oil does not dissolve gases in the atmosphere internal to the RF transmitter.

Abstract: Vacuum deaerators and methods of using for deaeration comprise a vessel having side walls and a cover. The vacuum deaerator further comprises at least one vacuum source coupled to the vessel, and an open-ended distributor plate comprising outer edges spaced from the walls of the vessel. Additionally, the vacuum deaerator comprises a drive shaft configured to rotate the distributor plate, and at least one feed port configured to provide a liquid comprising entrained gases to a surface of the distributor plate. The distributor plate is configured to deaerate the liquid by substantially removing entrained gases from the liquid through the application of centrifugal force.

Abstract: A fluid separator device allows for introducing air entrained in a liquid flow to a centrifugal pump in a manner that will not allow the pump to become gas bound. One example device designed according to this invention includes a housing having an inlet and an outlet downstream of the inlet. An air chamber is positioned on an opposite side of the inlet from the outlet. An air flow passage allows air from the air chamber to be introduced near a rotor assembly input of a centrifugal pump such that relatively small air bubbles are introduced to the liquid flow through the rotor assembly in a manner that prevents the air bubbles from recollecting into a larger bubble that would otherwise interfere with the centrifugal pump operation.

Abstract: A method for treating a waste product from a chemical processing plant. Chemical processing plants such as oil refineries produce sour water waste that includes ammonia and hydrogen sulfide. The sour water is typically steam stripped to form a vapor stream including water, the ammonia and the hydrogen sulfide. The vapor stream is converted into a concentrated ammonium sulfide solution using a scrubber unit that includes a cooling and quenching column. Concentrating the byproducts provides for more efficient transportation of the concentrate from several refineries to a remote, centralized purification facility.
