Selecting multiphase pumps
- Ingersoll-Dresser Pump Canada Inc., Brantford, Ontario (Canada)
Multiphase pumps in petroleum applications today must handle liquid products containing large amounts of gas, and often including water and sand as well. In the past, gas was commonly separated and flared off at the well head, and only liquid product was piped along for further processing. Using this setup, processing the gas as well as the liquid requires separators, compressors and dual pipelines. Rotary two-screw units are ideal for multiphase use, as they can pump any product that can be introduced into the suction passages of their screws. These devices also effectively handle heat generation from compressed gases. To select units for multiphase applications, an engineer should be familiar with these pumps and how they work. This article discusses rotary-screw pumps and how to effectively select a unit for multiphase service.
