Reactor Vessels, Absorbers and Stripper

Reactor Vessels, Absorbers & Strippers Installer | Process Columns | ASME Sec VIII, ISO 9001 | O&G Petrochemical "Reactor Vessels, Absorbers, and Strippers – Process Pressure Vessel Installation and Integration Contractor for Oil & Gas and Petrochemical Applications

Reactor Vessels, Absorbers, and Strippers are high-specification process equipment items performing chemical reaction, mass transfer, and component separation duties at the heart of refinery hydrotreating, hydrocracking, gas sweetening, amine treating, and petrochemical process units. As an experienced process equipment installation and integration contractor, we deliver mechanical installation, internal assembly, piping tie-in, and commissioning support for reactor vessels, absorber columns, and stripper columns across oil and gas and petrochemical facility projects.

Our installation scopes for reactor vessels encompass high-pressure reactor setting on reactor saddles or skirt foundations, flange management and stud bolt tensioning to specified torque and sequence requirements, catalyst loading support coordination, internal basket and distributor tray installation or inspection, thermometer well and quench injection nozzle connections, and process piping tie-ins for feed, effluent, quench, and recycle streams. Hydrotreating and hydrocracking reactors operate at elevated pressures and temperatures with hydrogen-rich service, requiring particular attention to material compatibility, flange seating integrity, and bolt tensioning precision.

Absorber column installation packages cover column setting, internal packing or tray assembly verification, amine or solvent inlet distributor installation, gas inlet and outlet nozzle connections, sump and liquid outlet connections, and interface with the lean and rich amine circulation piping. Amine gas sweetening absorbers and physical solvent absorbers for acid gas removal (CO₂, H₂S) from natural gas streams are common applications requiring corrosion-resistant internals and careful solvent distribution system installation.

Stripper column packages encompass reboiler connection piping, overhead vapour outlet and condenser connections, reflux inlet nozzle alignment, liquid drawoff connections, and internal tray or packing inspection and installation. Amine regenerator strippers, sour water strippers, glycol regeneration columns, and hydrocarbon stripper columns are typical applications in gas processing and refinery utility and treating units.

All mechanical installation and integration activities comply with ASME Section VIII Division 1 and 2 pressure vessel codes, applicable API recommended practices for pressure vessel inspection and installation, ASME B31.3 for process piping connections, ISO 9001 quality management, and project-specific ITPs and QA/QC documentation requirements. Our customized reactor, absorber, and stripper installation solutions ensure precise, code-compliant mechanical installation supporting safe and efficient process operation across oil and gas and petrochemical facilities in the GCC and regional markets."
