Frequently Asked Questions (FAQs)
1. How do you address high-temperature design challenges in petrochemical applications?
Our approach to high-temperature design includes careful material selection meeting applicable API and ASME requirements, proper consideration of creep and stress-rupture properties, specialized high-temperature welding procedures, comprehensive PWHT (Post-Weld Heat Treatment) protocols, and design features that accommodate thermal expansion and cycling. For extreme temperature applications, we provide specialized refractory linings, multi-layer insulation systems, and enhanced monitoring capabilities for temperature profiling.
2. What strategies do you employ for hydrogen service in refineries?
For hydrogen service, we follow API RP 941 guidelines, selecting appropriate materials with verified resistance to hydrogen attack and embrittlement. We incorporate PWHT to reduce residual stresses, specify proper welding procedures with controlled heat input, and perform comprehensive NDE including specialized techniques for detecting hydrogen damage. Our documentation includes detailed hydrogen service verification and material certification specifically addressing hydrogen compatibility at operating temperatures and pressures.
3. How do you manage corrosion concerns with various petrochemical process streams?
We address corrosion through detailed process stream analysis, identifying potential corrosion mechanisms such as sulfidation, naphthenic acid corrosion, ammonium bisulfide corrosion, or high-temperature hydrogen attack. Based on this analysis, we select appropriate materials, implement suitable corrosion allowances, specify specialized weld overlays or linings where needed, and design for monitoring and inspection access. For particularly aggressive environments, we can provide specialized alloys or clad construction.
4. What insulation systems are most appropriate for high-temperature petrochemical processes?
For high-temperature petrochemical processes, we typically recommend multi-layer insulation systems combining calcium silicate, mineral wool, or ceramic fiber materials with appropriate temperature-specific layers. These systems are designed with careful attention to expansion joints, support clearances, and weather barriers. For processes with temperature cycling, we incorporate specialized designs to prevent insulation crushing and moisture intrusion, while maintaining optimal thermal performance throughout the vessel’s service life.
5. How do your vessels address the unique requirements of catalyst-based processes?
Our vessels for catalyst-based processes incorporate specialized features including optimized internal geometry for catalyst distribution, appropriate nozzle configurations for catalyst loading and unloading, specialized internals for flow distribution, temperature monitoring arrays for hotspot detection, and materials selected for compatibility with specific catalysts and reaction conditions. We can also provide custom access ports for catalyst sampling, specialized support grids, and provisions for catalyst regeneration systems.
