Abstract
The Webre steam-water separator design is widely used in New Zealand, Philippines, Indonesia, Kenya and elsewhere in the world. It has been very successful with a separation efficiency claimed to be as high as 99.97%. While this seems adequate, 0.03 % brine carry over equates to about 0.24 TPH for a 100MW plant. The paper looks at designs and the operation of new and old separators and proposes a new equation to calculate separator efficiency. It then presents a conceptual design to improve the separation efficiency by trapping creep water. The design also reduces the pressure drop across the separator and improves access for internal vessel inspection.
