An agitation/defoaming device is provided, which can independently control revolving and rotational motion and can change a rotational direction relative to a revolving direction without a two-system rotary drive. The apparatus includes a rotary driving source, a braking device for rotary motions; first and second rotors revolved around revolving shaft, and first and second rotational bodies and container holders pivotally supported by the first rotor. A braking force is applied to the second rotor revolving along with the first rotor, generating a rotational motion, which is transmitted to either the first or second rotational body according to the revolving direction of the first rotor. The rotational motion is then transmitted from the first or second rotational body to the container holder through the first rotational body, thereby transmitting to the object the rotational motion according to the revolving direction while revolving the object.

A froth coalescing device includes a froth receiving chamber with a vent, and a vertical membrane arranged between the vent and a gas out port of the froth coalescing device. The vent is arranged to vent gas in a direction that is different from a direction of travel of froth in the froth receiving chamber.

A sterile foam breaking system, (14, 42, 52) includes a foam collector (20) having an opening (26), configured to be disposed in a source (12) which generates foam. The sterile foam breaking system (14, 42, 52) further includes a non-coated type suction unit (23) coupled to the foam collector (20). The non-contact type suction unit (23) is configured to transfer the foam via the opening (26) of the foam collector (20) and break a portion of the foam to generate a first quantity of liquid droplets. The sterile foam breaking system (14, 42, 52) additionally includes a foam breaking unit (28, 44, 54) coupled to the non-contact type suction unit (23). The foam breaking unit (28, 44, 54) is configured to receive remaining portion of the foam and the first quantity of liquid droplets and break the remaining portion of the foam to generate a second quantity of liquid droplets.

An oxidation-reduction desulfurization system includes a reactor vessel with sour gas inlet at the bottom and a gas outlet at the top. A primary stage phase separator includes a vertically-oriented pipe with an inlet located inside the reactor vessel. The ratio of the reactor vessel diameter to the pipe inlet diameter is in a range of 2:1 to 5:1. Surface foam and non-gaseous multi-phase mixture including emulsion flow into a partially gas-filled upper section of the vertically-oriented pipe and freefall to a lower level, thereby facilitating mechanical breaking of the foam and the emulsion. A secondary stage phase separator connected to the gas outlet separates non-gaseous surge from sweet gas. Valves and a controller automatically maintain target levels of the non-gaseous multi-phase mixture and non-gaseous surge.

A combustion engine includes a combustion section; a fuel delivery system for providing a fuel flow to the combustion section, the fuel delivery system including an oxygen reduction unit for reducing an oxygen content of the fuel flow; a thermal management system including a heat sink heat exchanger, the heat sink heat exchanger in thermal communication with the fuel delivery system at a location downstream of the oxygen reduction unit; and a control system including a sensor operable with the fuel delivery system for sensing data indicative of an operability of the oxygen reduction unit and a controller operable with the sensor, the controller configured to initiate a corrective action based on the data sensed by the sensor indicative of the operability of the oxygen reduction unit.

A method of mitigating fouling in a delayed coking unit heater may include forming a plastic mixture including a plastic material and a carrier. The plastic mixture may be combined with a coker feedstock upstream of a coke drum.

A floor cleaning machine is provided. The floor cleaning machine includes a solution tank for a cleaning solution. A pre-canister sensor receives the cleaning solution and measures the concentration of any dissolved solids. A canister assembly receives a portion of the cleaning solution from the pre-canister sensor and dissolves portions of a solid chemical form into the cleaning solution thereby forming blended droplets. The canister assembly has a spray nozzle positioned vertically above the solid chemical form. A post-canister sensor receives a mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. The post-canister sensor measures the concentration of any dissolved solids within the mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. A comparison of the baseline and post-canister measurements outside of a desired range results in replacement of the solid chemical form.
