Desalter design manual

 · This design guideline covers the basic elements of Crude Unit Desalter System design in sufficient detail to allow an engineer, operations or maintenance personnel to understand the design, operation and maintenance criteria for a crude unit Desalter system with the suitable water wash flow, injection water, and settling velocity. PROCESS DESIGN OF CRUDE OIL ELECTROSTATIC DESALTERS (PROJECT STANDARDS AND SPECIFICATIONS) Page 5 of 12 Rev: 01 April 3. Operating and mechanical design conditions The following conditions shall be specified by the Company: a. Operating pressure of the desalter (minimum pressure must be sufficient to maintain desalter content in liquid.  · desalting of crude oil pptdesalter design manual desalter water ph desalter sizing calculation desalter transformer. Consistent and efficient desalter operation requires reliable internal electrical grids to prevent the grids from shorting out. Manual spit valves were used to. Electrostatic D h d i and D El i Dehydration d Desalting.

Crude Oil Desalting technology is utilised to remove residual salt to meet these requirements. The type and size of the Desalter that is used is dependent upon a number of fundamental factors such as pressure, temperature, fluid viscosity and flow-rate, as well as customer requirements relating to maximum salt allowed in the product oil stream. This design guideline covers the basic elements of Crude Unit Desalter System design in sufficient detail to allow an engineer, operations or maintenance personnel to understand the design, operation and maintenance criteria for a crude unit Desalter system with the suitable water wash flow, injection water, and settling velocity.
