Abstract: A fluid separation apparatus for separating a fluid mixture including at least two fluids having different densities comprising a vessel having a vortex generation zone located within a fluid reservoir which includes a vortex generation wall which increases the rotational velocity of a fluid mixture flowing through the vortex generation zone and directs the fluid mixture from the fluid inlet toward the upper surface of the fluid reservoir. The vessel also includes a fluid inlet which extends into the vortex generation zone; a first fluid outlet through which the less dense fluid exits the vessel; and a second fluid outlet through which the denser fluid exits the vessel. The apparatus further comprises a gas bubble generator which introduces gas bubbles into at least a portion of the fluid mixture before the fluid mixture enters the vessel through the fluid inlet.

Abstract: A gas scrubbing apparatus including at least two modules, each module including at least one process vessel for a gas scrubbing process, each process vessel being selected from an absorber, a regenerator, a scrubber, a reboiler, a heat exchanger or a combination thereof. Each process vessel has top wall, a base wall, and at least three sidewalls formed from a cementitous material. Each process vessel has inlet and outlet ports for fluid entering and leaving the process vessel when in use, formed within at least one of the top wall, base wall, or sidewall of each process vessel. The sidewalls of each process vessel define a polygon shaped cross-section, and at least one side wall of a first process vessel in a first module can be connected or abutted to at least one side wall of a second process vessel in a second module.

Abstract: A stripping gas recycle process for a stripper is fed a water containing glycol and a stripping gas. The stripping gas removes a water content from the water containing glycol to produce a dried glycol and a wet stripping gas. The recycle system includes at least one stripping gas separation process, with the gas separation process being fed wet stripping gas from a stripper and separating the water content from the wet stripping gas, to produce a water containing fraction and a drier stripping gas fraction. The drier stripping gas fraction is fed into the stripper.

Abstract: A bubble generator for generating gas bubbles for a flotation vessel, the bubble generator including at least one inlet through which a water stream can enter the bubble generator; at least one pair of electrodes capable of electrically decomposing water to create gas bubbles; and at least one outlet through which water entrained with gas bubbles can exit the bubble generator. In use, at least one of the outlets is in fluid communication with a flotation vessel containing waste water including contaminants, the gas bubbles being used to separate at least a portion of the contaminants from the waste water in the flotation vessel.
