Lethal Service Pressure Vessels for Oil and Gas Processing | Roben Manufacturing
Lethal Service Vessels for the Oil and Gas Processing Industry
Oil and gas processing frequently encounters hydrogen sulfide (H2S) and other toxic components in produced fluids. Sour gas processing, sulfur recovery, and amine treating all involve lethal concentrations of H2S that demand specialized pressure vessel design and materials. Beyond H2S, refineries use hydrogen fluoride for alkylation and various other lethal substances in downstream processing. These applications require vessels meeting both ASME lethal service requirements and NACE standards for sour service.
Industry-Specific Requirements
Oil and gas lethal service vessels must resist hydrogen sulfide attack while meeting ASME lethal service requirements—a challenging combination that restricts material selection and demands careful attention to hardness limits, welding procedures, and heat treatment. NACE MR0175/ISO 15156 provides materials and manufacturing guidance for sour service that must be integrated with lethal service code requirements. Roben Manufacturing’s experience with sour service lethal vessels ensures designs meet both sets of requirements.

Frequently Asked Questions
What defines lethal service under ASME Code?
ASME Code defines lethal service as vessels containing poisonous gases or liquids of such a nature that a very small amount mixed or unmixed with air is dangerous to life when inhaled. This designation triggers mandatory additional requirements including 100% radiographic examination of welds, post-weld heat treatment, and enhanced documentation.
What materials does Roben recommend for oil and gas processing lethal service?
Material selection depends on the specific substances handled, process conditions, and corrosion environment. Our engineering team provides material recommendations based on your specific application, considering both technical performance and code compliance requirements. We work with stainless steels, nickel alloys, titanium, zirconium, and specialty alloys as appropriate.
How does Roben support our PSM/RMP compliance?
Roben’s comprehensive quality documentation directly supports Process Safety Management and Risk Management Program mechanical integrity requirements. We provide baseline data for inspection programs, maintain fabrication records, and can format documentation packages for your PSM files. Our engineering team is available to support mechanical integrity reviews and audits.
