This disclosure includes mixers and methods of mixing. Some mixers comprise at least one contacting element, each defining at least one mixing channel. Each of the mixing channel(s) can have a cross-sectional area that decreases in a downstream direction to accelerate any pipe fluid flowing through the mixing channel. The contacting surface of each of the mixing channel(s) can deflect at least a portion of any pipe fluid flowing through the mixing channel until the contacting surface ends at an edge at a point of maximum constriction. Each of the contacting element(s) can define one or more injection path(s) to at least one of the contacting surface(s), each configured to inject admixture fluid onto the contacting surface such that the admixture fluid is entrained by pipe fluid over the edge.

Multi fluid injection mixer

Multi Fluid Injection Mixer for injecting gas and/or liquid as admixture fluid to gas and/or liquid flowing through a pipe, and homogeneously mixing the admixture fluids and pipe fluids, said injection mixer constituting a section of the pipe, distinguished in that the injection mixer is comprising: at least one contacting element having at least one contacting surface facing and deflecting some of the pipe fluid flow, forming a constriction to the internal cross-section of the pipe, such that the pipe fluid flow is accelerated and fluid flowing in the vicinity of said surface is deflected to flow along the surface until the surface end over a sharp edge at the point of maximum constriction and flow velocity, at least one injection element arranged with a fluid connection to said surface of the contacting element, such that admixture fluid can be injected onto said surface and along said surface be entrained by the flowing pipe fluid over the sharp edge, but for a contacting element formed as a contracting pipe section at least two injection elements are provided.

The use of turbulent contactors to simultaneously absorb selected acid gas components from a gas stream and flash off hydrocarbons entrained in a liquid stream which include a solvent or reagent for the selected gas component. In particular, the method comprises feeding the gas stream and liquid stream into a first contactor where they are contacted co-currently and subjected to turbulent mixing conditions, and passing the multi-phase flow from the first contactor to a second contactor. The multi-phase flow from the second contactor is subsequently separated into a gas phase and a liquid phase.

Acid gas removal

The use of a turbulent contactor to absorb a selected gas component from a gas stream. The invention particularly applies to a method of distributing a liquid into a gas stream which comprises providing a liquid to an annulus at the periphery of a pipe in which a gas stream is flowing, the gas flow drawing the liquid into a film along the inner surface of the pipe to a sharp edge at the end of the pipe at which point the liquid breaks off the surface of the pipe and mixes intimately with the gas.

Method for mixing fluids

A method of removing acid gas components from a gas mixture. Certain embodiments of the method involve bringing the gas mixture into contact with a liquid solvent or reagent for the acid gases in a first turbulent contactor and subjecting the gas mixture and liquid to turbulent mixing conditions. This causes the acid gas to be absorbed by the solvent or reagent. The fluid mixture is passed into a second turbulent contactor and subjected to further turbulent mixing conditions causing further acid gas to be absorbed by the solvent or reagent. Optionally the fluid mixture is separated into a gas phase and liquid phase.

Fluid separation system

A system for removing water from natural gas which comprises: bringing the natural gas into contact with a liquid including an absorbent for the water; subjecting the natural gas and liquid to turbulent mixing conditions thereby causing the water to be absorbed by the absorbent; and separating a natural gas phase with reduced water content and a liquid phase including the absorbent and absorbed water. The mixing is conducted in a turbulent contactor ( ) including a gas inlet ( ), a liquid inlet ( ), an outlet ( ) leading to a venturi passage ( ) and a tube ( ) extending from the outlet ( ) back upstream. The tube ( ) may be perforated and/or spaced from the periphery of the outlet ( ).

Method and apparatus for the drying of natural gas

The use of a turbulent contactor to absorb a selected gas component from a gas stream. The invention particularly applies to a method of removing selected gas components from a gas stream which includes: bringing the gas stream into contact with a liquid including a solvent or a reagent for the selected gas component in a turbulent contactor, the contactor including a gas inlet, a liquid inlet, an outlet leading to a venturi passage and a tube extending from the outlet back upstream, the tube being perforated and/or being spaced from the periphery of the outlet; subjecting the gas stream and liquid to turbulent conditions in the contactor thereby causing the gas component to be absorbed by the solvent or reagent.

A method for removing acid gas components from combustion gas and natural gas. The method includes bringing the gas mixture into contact with sea water and subjecting the gas mixture and sea water to turbulent mixing conditions. This causes the acid gas to be absorbed by the sea water. The sea water can be disposed of offshore without any detrimental effect on the environment.
