Abstract: 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.
