摘要： Disclosed herein is a device and methods for enhancing oil separation from produced water. One such method includes mixing a multiphase fluid having at least a water phase and an oil phase with a flotation gas, according to at least one operating condition, so as to produce an enhanced multiphase fluid having bubbles of the flotation gas therein. The oil phase is then separated from the water phase using a separator. At least one property associated with the enhanced multiphase fluid is monitored. The operating condition is adjusted as a function of the monitored property so as to increase a percentage of the oil phase separated from the water phase by the separator over a percentage of the oil phase that would be separated from the water phase without adjustment of the operating condition.

摘要： A pump valve vacuum degassing device including a receiving funnel, a loading member, a vacuum processing chamber, and a discharging member sequentially connected in a sealed manner and having internal cavities in mutual communication. The receiving funnel can achieve complete and thorough slag avoidance, and does not require any manual control operation. The vacuum processing chamber is provided with a barrier member configured to increase a falling time duration of liquid steel and sufficiently spread the liquid steel, so as to create a more ideal and sufficient condition for removal of harmful gases. The U-shaped structure of the loading member and discharging member ensures maintenance of a vacuum environment during off-time of the device and retaining of airtightness, such that air ingress diminishing a vacuum condition no longer occurs. The device can realize continuous manufacturing in a vacuum.

摘要： The ventilation pipe 60 having the openings at both the ceiling side and the bottom side is provided in the area where the rectification boards 50a to 50f are arranged, thereby nitrogen released from water (nitrogen released from water based on that gas dissolved in water is substituted by oxygen) can be moved to the ceiling side of the retainer body through the ventilation pipe 60. Thereby, nitrogen can be effectively exhausted from the exhaust opening 30a, thus it can be restrained that nitrogen is accumulated in the retainer body 10. Accordingly, it can be restrained that oxygen concentration (partial pressure) in the retainer body 10 decreases. Since oxygen quantity dissolved in water is increased, gas dissolved in water can be effectively substituted.

摘要： A release device for releasing a specific gas component from a rich absorption liquid which is an absorption liquid containing the specific gas component absorbed therein, the release device including a channel structure internally having a release channel which is connected to a rich absorption liquid supply unit so as to receive the rich absorption liquid supplied from the rich absorption liquid supply unit and connected to a liberating agent supply unit so as to receive a liberating agent supplied from the liberating agent supply unit, the liberating agent having a boiling point lower than a boiling point of the rich absorption liquid and being incompatible with the rich absorption liquid. The release channel is a microchannel configured to guide the received rich absorption liquid so that the received rich absorption liquid releases the specific gas component while flowing. The release channel has a treatment channel part which guides the rich absorption liquid and vapor of the liberating agent while bringing the rich absorption liquid and the vapor of the liberating agent into contact with each other so that the specific gas component is liberated from the rich absorption liquid to be transferred to the vapor of the liberating agent.

摘要： The object is to prevent deterioration and loss of dicyanobenzene in producing dicyanobenzene by ammoxidation of xylene to thereby achieve industrial and economical advantage in producing of dicyanobenzene. The method for producing dicyanobenzene of the present invention includes: contacting a xylene-ammoxidation reaction gas containing dicyanobenzene in ammoxidation of xylene with an organic solvent so as to obtain a dicyanobenzene-absorbing solution; contacting the dicyanobenzene-absorbing solution with a basic aqueous solution containing a salt such as ammonium carbonate so as to extract a water-soluble salt formed by neutralization reaction between carboxylic acid in the dicyanobenzene-absorbing solution and a base in the basic aqueous solution into an aqueous phase; separating the mixture of the dicyanobenzene-absorbing solution and the basic aqueous solution into an organic phase and an aqueous phase; decomposing the salt such as ammonium carbonate contained in the organic phase for separation of the salt from the organic phase; and distilling the organic phase to separate low boiling point compounds contained in the organic phase from the organic phase so as to obtain dicyanobenzene.

摘要： A gun barrel tank for treating raw crude oil mixtures. The fluid mixture enters through a degassing boot where gas is separated from the liquid. The liquid travels through a central column to a horizontal hydraulic distributor located in the lower area of the tank, first entering a central distributor trough, then passing into open bottom horizontal inverted lateral troughs and finally out through a plurality of metering orifices provided near the top edges of the lateral troughs to provide uniform distribution of the liquid in the tank. A circular oil collection trough provided at the top of the tank has a plurality of V-shaped notches on its top edge over which oil flows into an oil collection trough to provided uniform collection of the separated crude. A circular water collector in the bottom of the tank removes separated water, and solids are removed from the bottom of the tank.

摘要： The invention provides, in one aspect, a system for recirculating ozonated liquid. The system includes a contactor including at least two inlets and at least two outlets. The contactor is in fluid communication with a first liquid source at a first contactor inlet and a second liquid source at a second contactor inlet, and the second contactor inlet receives gas that purges at least a portion of gas from liquid received at the first contactor inlet. The purged gas exits the contactor at a first contactor outlet. The contactor is in fluid communication with the second liquid source at a second contactor outlet, and the contactor drains at least a portion of the liquid in the contactor, the drained liquid exiting the contactor at the second contactor outlet. The contactor includes a third inlet in fluid communication with the first liquid source, the third inlet allowing the first liquid source to release liquid at an ambient pressure.
