Purpose

Reduce free and dispersed water in crude oil upstream of final treatment, storage or export.

Arrangement and integration

Equipment functional diagram

The diagram identifies the principal process duties, equipment connections and product handover points. Final scope, redundancy and battery limits are established from project data.
