Generic desalter unit

Introduction

This is a generic desalination unit designed to separate water from other stream components. The user must specify target water recovery. The unit assumes complete separation of ions from the liquid stream (100 % rejection).

Degrees of Freedom

For inlet conditions:
  • temperature

  • pressure

  • component mass compositions

Unit overall operation:
  • water recovery

  • solids concentration in brine (User must provide tracked solids list)

  • water content of the brine (User must provide tracked solids list)
