FORMULATIONS OF COPOLYMERS BASED ON ALKYL ACRYLATES USED AS DEFOAMERS OF HEAVY AND SUPER-HEAVY CRUDE OILS

This invention is directed to a method for defoaming crude oil by the addition of copolymers based on silicone free alkyl acrylics defoamers for crude oils with densities between 10 and 40° API. The alkyl acrylic copolymers at conditions similar to those of gas-liquid separators are efficient foam formation inhibitors in heavy and super-heavy crude oils to reduce foam levels between 15 and 50% faster than non-dosed crude oil. Some acrylic copolymers exhibited a greater efficiency as defoamers than commercial silicones, which promote the defoaming only 20 or 25 vol % faster than the natural foam collapse. Silicones as defoamers present serious problems as the formation of deposits and the deactivation of catalysts in the refining processes. These problems have originated a series of interdictions to use silicon based defoamers and new chemical compounds completely silicon free are required to control the foam levels in the gas/petroleum separation tanks. 2.

Device For Inducing A Vortical Fluid Flow

A device for inducing a vortical fluid flow includes a central hub and a plurality of vanes that extend radially from the central hub. Each vane has an interior edge that extends substantially along the length of the hub, a top edge that tapers from narrow to wide in the direction from an inlet end towards an outlet end of the device, a vertical outer edge, and an outside corner at the outlet end bent inwardly at a 45-degree angle to a longitudinal axis of the central hub.

Flow Conditioner and Method for Optimization

A flow conditioner for a circular pipe having an axis. The flow conditioner includes a plate having a face to be disposed in the circular pipe with the face of the plate perpendicular to the axis of the pipe. The plate has a central circular passage area through which fluid flows surrounded by two or more concentric arrays of segmented annular passages for fluid flow defined by separating and subdividing ligaments, with at least one subdividing ligament having a width different than a width of a second subdividing ligament. Alternatively, or in addition, there is at least one array of annular passages having a radial width different than a radial width of a second array of annular passages and at least one subdividing ligament having a width different than a width of a second subdividing ligament.
