Air-Cooled Heat Exchangers Removal for Chemical Processing Facilities

Air-Cooled Heat Exchangers removal context in Chemical Processing

Air-cooled heat exchangers (ACHEs) are devices that reject waste heat from process fluids directly to the atmosphere, eliminating the need for cooling water. Installed removal from a chemical plant also depends on the actual process, residual service, isolation status, surrounding systems, and facility access described in the chemical processing 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 chemical processing system. Unknown conditions should be identified as unknown.

• Identify material of construction (e.g., carbon steel, stainless steel, titanium, high-alloy).
• Check for specialized designs like low hold-up volume or specific plate angles.
• Review NDE (Non-Destructive Examination) records such as Eddy Current Testing (ECT) or IRIS.
• Consider the large physical footprint of modular units (e.g., 90 ft by 180 ft).
• Plan for lifting and transporting heavy tube bundles and structural components.
• Account for the removal of large fans (up to 60-foot diameter) and their driver motors.

Dismantling, loading, and freight planning

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

• Consider the large physical footprint of modular units (e.g., 90 ft by 180 ft).
• Plan for lifting and transporting heavy tube bundles and structural components.
• Account for the removal of large fans (up to 60-foot diameter) and their driver motors.
• Ensure safe handling of any residual process fluids within the tubes.
• Requires rigorous isolation and purging of hazardous or corrosive media (e.g., acids, amines, hydrogen sulfide).
• Must account for potential residual chemical exposure during dismantling.
• Proper neutralization and flushing of chemical cleaning agents is required prior to transport.

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.
