摘要： A small-scale dynamic simulator for crude oil refinery desalters has a pressurized oil deviblis configured to hold a supply of crude oil and a water deviblis configured to hold a supply of wash water. At least one chemical feed pump selectively adds emulsion breaker chemicals to the desalter simulator and a low shear metering pump is configured to pump crude oil and wash water through the desalter simulator. An emulsion forming device forms a crude oil-wash water emulsion that is then received in a desalter vessel. The desalting vessel is fitted with electric grids which simulate those found in electric desalters. The emulsion is resolved within the desalter vessel with the assistance of the emulsion breaker chemicals so the wash water and crude oil form distinct phases, with substantially desalted crude oil removed from an upper portion of the desalter vessel and substantially oil-free wash water removed from a bottom portion of the desalter vessel. A portion of the desalter vessel is substantially transparent to allow visualization of the demulsification process and at least one light source is positioned adjacent to the desalter vessel to aid in visualization of a rag layer formed in the desalter vessel. A heated jacket surrounds the desalter vessel to maintain the desalter vessel at the desired temperature.

摘要： A process for testing the effectiveness of demulsifying additives on oil/water emulsions includes adding samples containing differing combinations of oil, water and demulsifier to a plurality of elongate reactor vials, wherein each the elongate reactor vial has a longitudinal axis extending from its bottom to its rim. The plurality of reactor vials are placed into a reaction block mounted on a platform of a shaker, wherein the reactor vials are received in stations of the reaction block in a vertical orientation such that the longitudinal axis of each reactor vial is perpendicular to the platform. The reaction block is pivoted the so that the longitudinal axis of each reactor vial is parallel with the platform in a horizontal orientation. The method further includes agitating the reactor vials with the shaker to simultaneously form an oil/water emulsion in each reactor vial while the reactor vials are in the horizontal orientation and then pivoting the reaction block to return the reactor vials to a vertical orientation. The demulsification of the oil/water emulsion in the plurality of reactor vials is observed with the reactor vials in the vertical orientation. In one embodiment, the method further includes using an imaging device to record the demulsification of the oil/water emulsion.

摘要： Methods for reducing calcium deposition along surfaces in contact with the water phase of a resolved water/oil emulsion are disclosed. High calcium crude oil and the like are contacted with a sequestrant to form a sequestered calcium containing complex that partitions to the water phase in the resolved emulsion. A specifically formulated polymeric deposit control agent is added to the water phase to inhibit calcium deposit formation therein and along surfaces in contact with the water phase.
