The Process

Gas processing facilities employ a variety of “knock-out” devices and multistage separators to remove as much water vapor from the natural gas stream as possible. The produced water is reinjected for pressure maintenance, enhanced oil recovery, or is ready for disposal.

The Problem

The “produced water” contains varying levels of solid contaminants including iron oxides, iron sulfides and asphaltines (tar-like particulate) that must be eliminated prior to disposal or injection. Produced water filtration must remove solid contaminants efficiently and provide consistent filtration performance. Disposal of the produced water requires that the water quality meet local standards for Total Suspended Solids (TSS). When re-injecting produced water, any bypass or unloading of contaminant into the high pressure injection stream can cause injection well plugging or fracture, requiring expensive work-overs.

The Solution

Absolute rated filter cartridges and bags provide the required performance necessary in this critical application. 5 micron absolute  is recommended for optimal performance.
