Pumps in oxygen scavenging

Published:  13 March, 2015

Following site trials pumping aggressive oxygen scavenging chemicals, Occidental Petroleum in Oman reports it has approved Hydra-Cell pumps, from WANNER INTERNATIONAL, for use in one of its most demanding applications.

Dissolved oxygen in injection water can cause destructive oxygen corrosion to metal pipes and process equipment. By-products of this corrosion form sludges that cause plugging and blockages. This oxygen is generally removed through the introduction of oxygen scavenging chemicals into the high-pressure stream.

Oxygen scavenging chemicals such as sodium and ammonium bisulfites are renown for damaging pumps. Occidental Petroleum had trialled several types of pumps and all were found wanting, the majority springing leaks through dynamic seals in a matter of days or weeks. A Hydra-Cell P200 with mechanical speed control has however solved the problem.
