Processing sour gas (H 2S) requires equipment that can withstand severe chemical attack and hydrogen embrittlement. Standard thermal systems break down quickly under these conditions, leading to dangerous leaks, unplanned shutdowns, and expensive repairs.Our specialized ATEX-certified circulation heaters are custom-engineered for sour gas applications throughout the Middle East and Qatar. We combine advanced metallurgy with precise temperature control to ensure your gas streams are safely heated well above their dew points without compromising the structural integrity of the system
For gas processing facilities across the Middle East and Qatar, maintaining safety and uptime requires specialized thermal equipment. Standard process heaters simply cannot survive the aggressive corrosion associated with sour service. You need a robust, certified solution designed specifically to handle these aggressive gases safely over a long operational lifespan.
Understanding the Risks of Sour Gas Heating
Heating sour gas is critical to prevent hydrates from forming and to keep the gas well above its dew point during transport and processing. However, the process comes with serious technical hurdles that require expert engineering:
- Sulfide Stress Cracking (SSC): When high-strength steels are exposed to H2S and moisture, hydrogen atoms penetrate the metal lattice, causing it to become brittle and crack under tensile stress.
- Localized Overheating: If a heater’s skin temperature rises too high, it can cause the process gas to crack or decompose, accelerating chemical attack on the heating elements.
- High Operating Pressures: Sour gas streams often run at high pressures, meaning the heating vessel itself must act as a flawlessly sealed pressure vessel.
Engineered for Compliance and Longevity
A trusted sour gas heater must be built from the ground up according to strict international metallurgy standards. We engineer our heating systems to meet the exact demands of hazardous gas environments.
Strict NACE Compliance
Every component that comes into contact with the process fluid complies fully with NACE MR0175 and ISO 15156 standards. This ensures that the materials used are certified to resist cracking in hydrogen sulfide environments.
Premium Alloy Selection
We don’t cut corners on material selection. Depending on your specific gas composition and moisture levels, our heating elements and pressure vessels are fabricated using high-grade corrosion-resistant alloys. Materials like Incoloy 825, Inconel 625, and heavy-wall 316L stainless steel provide the necessary defense against pitting and chemical degradation.
ATEX Certified Safety
Explosion protection is mandatory. Our sour gas heaters carry full ATEX certification for Zone 1 and Zone 2 hazardous areas. The terminal enclosures feature flameproof protection concepts to ensure that any internal electrical arc or spark can never ignite the surrounding environment.
Fast Regional Delivery to Protect Your Schedule
We know that waiting months for critical replacement infrastructure is not an option when a plant turnaround is approaching or an unexpected breakdown occurs. Long lead times from overseas manufacturers can cost millions in delayed production.
By streamlining our engineering workflows and maintaining a dedicated supply of NACE-compliant raw materials, we provide exceptionally fast delivery times to sites across Qatar and the wider Middle East. We work closely with your logistics and engineering teams to ensure the equipment arrives on-site exactly when you need it, avoiding unnecessary administrative delays.
