Sour service metallurgy
H₂S partial pressure drives hardness limits, PWHT requirements and alloy selection under NACE MR0175 — decisions that cannot be reversed after fabrication.
Energy · Industry
Upstream, midstream and downstream filtration engineered for sour gas, produced water and the sand events nobody schedules.
- Aerosol carryover to compressor
- 0.1 ppmw
- Wellhead-rated housings
- 250 bar
- MR0175 compliant throughout
- NACE
The constraint
Separation that holds through sour service and sand.
Hydrocarbon service punishes filtration in three directions at once: H₂S attacks the metallurgy, sand arrives without warning at full line velocity, and produced water chemistry shifts as the field ages. Equipment specified for day-one conditions is often obsolete by year three.
Standards we work to
- ASME VIII Div. 1 & 2
- NACE MR0175 / ISO 15156
- API 614
- API 682
- ATEX / IECEx
Unpredictable sand loading
A sand slug at line velocity will collapse an under-designed basket into the pump. Structural rating matters more than filtration rating on this duty.
Amine and glycol carryover
Sub-micron aerosol losses are a direct chemical cost and a downstream fouling mechanism that gauges never reveal.
Water chemistry that drifts
Water cut, chloride content and scaling tendency all change as a field matures, so filtration must be specified against the field's tenth year, not its first.
