Waste-Heat Recovery Exchangers Removal for Oil and Gas Production Facilities

Waste-Heat Recovery Exchangers removal context in Oil and Gas Production

Waste-heat recovery exchangers are critical components in industrial energy efficiency, designed to capture and reuse thermal energy from high-temperature exhaust gases, cooling water, and hot equipment surfaces. Installed removal from a upstream or midstream facility also depends on the actual process, residual service, isolation status, surrounding systems, and facility access described in the oil and gas production evidence record.

The removal plan must be based on the submitted unit and site. This page does not imply a local crew, permit authority, preapproved lift, guaranteed pickup, or unconditional service availability.

Isolation and residual-service record

Before commercial or logistics commitments, document how both exchanger sides were isolated, drained, cleaned, released, and separated from the oil and gas production system. Unknown conditions should be identified as unknown.

• ASME U-stamp verification on nameplate.
• TEMA class designation (e.g., Class R for severe service).
• Material test reports (MTRs) for pressure-retaining components.
• Ensure complete isolation from high-temperature exhaust ducts and process fluid lines before removal.
• Verify the absence of hazardous or acidic residues from condensed flue gases.
• Plan for significant weight and size, often requiring heavy lifting equipment for shell-and-tube units.

Dismantling, loading, and freight planning

The physical plan should connect the waste-heat recovery exchangers configuration to verified dimensions, weight, lifting points, access, staging, carrier profile, and responsibility boundaries.

• Ensure complete isolation from high-temperature exhaust ducts and process fluid lines before removal.
• Verify the absence of hazardous or acidic residues from condensed flue gases.
• Plan for significant weight and size, often requiring heavy lifting equipment for shell-and-tube units.
• Cap and seal all connections to prevent environmental contamination during transport.
• Requires rigorous purging and steaming to remove residual hydrocarbons and hazardous gases (e.g., H2S) prior to disconnection.
• Heavy lifting equipment needed for large shell-and-tube units often found in production facilities.
• Specialized transport required due to significant weight and potential oversized dimensions.

Written scope before work

Dismantling, rigging, loading, freight, scheduling, and payment are conditional project functions. A written scope must identify responsible parties, safety release, access rules, exclusions, equipment boundaries, carrier requirements, and commercial terms before performance.
