OVERVIEW

Vessels subjected to 2,000,000 cycles of pressure variations over 20 years

Pressure Swing Adsorption is a chemical separation process in which a mixture of gases is passed through a bed of adsorbent media at high pressure. The CLIENT required a pressure vessel manufacturer to construct a set of multiple adsorbent vessels for a local project in Montreal, QC, Canada. These vessels are particular in that they will be subjected to 2,000,000 cycles of pressure variations over 20 years. Also particular was the need for precision of all dimensions to within 1/16’’ tolerance.

APPROACH

Full-turnkey engineering & fabrication

DIMARTECH provided the CLIENT with designs and calculations for an arrangement of six (6) identical vertical vessels with FEA calculations and fatigue analysis for the varying pressure conditions: load cases with various combinations of static and dynamic loadings for pressure, vacuum, seismic, loadings on nozzles, contents full of liquid.

DELIVERABLES

Achieved all project parameters from design to fabrication to testing

The vertical vessels were 36’’ diameter x 96’’ high. The tight collaboration between DIMARTECH and our CLIENT’s engineers resulted in meeting all project parameters with regards to design, fabrication and testing. As a result, the following processes and inspections were done: 100% PT on bevels and backgouged roots, 100% UT on plate materials and nozzle welds, 100% RT on all butt welds, 100% MT on all welds, Post Weld Heat Treatment.
