Abstract: A device for effecting heat transfer from a first fluid medium to a second fluid medium and for enhancing mixing and uniform distribution of the second fluid medium within the confines of a conduit. The device includes providing a core pipe for receiving the first fluid medium and a series of helically wound tubes in fluid communication with the core pipe along the longitudinal axis of the conduit. The second fluid passes within the conduit and is mixed by virtue of the static mixing effect of the helically wound tubes and engages in heat transfer as a result of the intimate contact between the second fluid, the core pipe and the helically wound tubes.

Abstract: A device for the injection and mixing of steam into a tank containing a fluid such as water. A primary steam conduit receives steam and discharges it into a plurality of secondary steam conduits. The primary steam conduit is provided with at least one mixing element for inducing an angular velocity to the steam passing through it. A plurality of secondary steam conduits are provided for receiving steam from the primary steam conduit and for discharging steam into the fluid contained in the tank. Each secondary steam conduit is also provided with at least one mixing element proximate the discharge ends of the secondary steam conduits wherein all such mixing elements induce a rotational angular velocity to the steam.

Abstract: A desuperheater for reducing the superheated state of steam located within a cylindrically-shaped conduit. The desuperheater injects water droplets counter to the direction of moving superheated steam within the conduit. Downstream of the water droplet outlet is a biscuit which is aligned along the longitudinal axis of the conduit to provide a series of separate mixing elements all inducing the same rotational sign to fluids passing therethrough.

Abstract: A stationary material mixing apparatus located within a conduit for mixing a low viscosity additive into a high viscosity moving stream. The apparatus includes a baffle which supports a plurality of coplanar passageways and, at mid-circle points between the passageways, a plurality of coplanar additive fluid ports.

Abstract: A device for enhancing the mixing and uniform distribution of fluids within a conduit. The device includes a core pipe which can optionally receive a first fluid and series of helically wound vanes wrapped about the core pipe employing the core pipe as a mandrel. Fluids entering the conduit are mixed by virtue of passing over and about the helically wound vanes while heat transfer can be effected by heat passing between the mandrel and the fluid passing over the vanes. Ideally, the vanes are wrapped about the mandrel at an angle of approximately 45.degree. thereto and adjacent layers of vanes are wrapped about the mandrel at opposite signs so that interstices are ideally created between vanes of approximately 90.degree..

Abstract: A steam injection heater for liquids. The liquids are carried by a conduit characterized as having an upstream end, downstream, substantially circular cross-section and tapered section. A steam inlet pipe is caused to pass through a side wall of the conduit for injecting steam at its outlet proximate the longitudinal axis of the conduit upstream with the tapered section. The steam inlet pipe further includes a mixing element of a configuration to cause steam emanating from the steam inlet pipe to enter the conduit as a rotating cone of steam for efficiently transferring heat energy from the steam to the moving stream of liquids.

Abstract: A stationary material mixing apparatus for mixing various components in a fluid stream. The mixing apparatus is in the form of a cone-shaped module containing a plurality of openings therethrough where within the openings are located mixing elements which induce a rotational angular velocity to the fluid stream. As preferred embodiments, the mixing apparatus, located within a conduit, can also contain a biscuit with further mixing elements and a series of either helically wound tubes or vanes further enhancing the mixing operation.

Abstract: A device for distilling a liquid feed which includes a core pipe and a first fluid in a series of helically wound tubes or vanes employing the core pipe as a mandrel. The liquid to be distilled passes over a series of interstices which are created by the helically wound tubes or vanes and a distillate recovered as a consequence.

Abstract: A device for mixing two or more fluids which includes an elongated hollow tubular member having a longitudinal axis which is constricted intermediate its ends. The constriction includes at least two orifices carrying a first fluid which are situated and sized within the hollow tubular member so that the orifices have a point of substantial mutual tangency. A fluid entry port is provided for discharging a second fluid at a point substantially coincident with the point of substantial mutual tangency of the orifices. The fluid entry port for discharging the second fluid is a second fluid discharge tube located at the point of substantial mutual tangency.

Abstract: A stationary material mixing apparatus in the shape of a cylindrical conduit being open at both ends. The conduit houses a plurality of mixing elements which are characterized as having no edges perpendicular to the longitudinal axis and which are sized and positioned within the conduit such that at any plane passing perpendicularly to the longitudinal axis, at least 75% of the circumference of the conduit is free of any mixing element.

Abstract: Apparatus for mixing or distributing a material or materials having no moving parts in which one or more elements are fitted into a conduit. Substantial radial displacement of material flowing in the conduit is achieved over a short distance with minimum pressure drop. Each element initially imparts a rotational vector to the material stream and then transforms the rotational vector to a lateral or radial vector.
