Desalination

NoDoC provides models for cost estimation of desalination units for the following types:

• Single-Stage Dehydrator

• Single-Stage Desalter

• Two-Stage Desalter

• Three-Stage Desalter

• Typical Operating Conditions and Performance

And for the following applications:

• Heavy Crude Desalting

• FCC Feed Desalting

• Distillate Treating

The components that are included in the NoDoC models are:

• Process Vessel

• Distribution System

• Electrodes and Transactors

• Mud Wash

• Level Control Devices

NoDoC considers followings as desalter estimation basis:

• Vessel Size

• Number of Stages

• Transactor Size and Power Consumption

• Crude Properties

Also NoDoC involved with the following factors that affect desalter operation and maintenance:

• Crude Oil Feed Rate and Quality

• Temperature/Viscosity/Density Relationships

• Electrical Field Intensity

• Wash Water Rate, Quality and Flow Configuration

• Emulsion Formation (Pumps, Exchangers, Valves, Mixers)

• Control of Water Level and Emulsion Layers

• Demulsifier Technology and Addition Rate

• Mud Washing and Brine Recycle.
