The thermal and mechanical design problems, with operation of the pebble bed heater over a -320°F to + 1850°F temperature range at 3,000 psig, with sudden exposure to a high flow of liquid nitrogen, are enormous. Cryoquip technology provided effective solutions.

All of Cryoquip's extensive capabilities in welding, machining, drilling and other manufacturing skills have been brought to bear in the challenging manufacturing process. Each pebble bed heater weighs approximately 75 tons, and heats 1,500,000 SCFH of LN2 to 1850°F.

The control valve element of a hydrogen pressure swing absorption plant fabricated by Cryoquip for Shell Oil, to be used at an overseas oil refinery. The skids, fabricated in one piece, each weigh approximately 65 tons and measure 80 feet long, 17 feet wide, and 13 feet high. They comprise five identical valve stations designed to control the flow of hydrocarbon products. The skid forms a small part of a larger oil refining process to produce gasoline and oils. Cryoquip is one of only a handful of skilled fabrication companies capable of designing and fabricating such complex valve skids within the confines of tight delivery schedules. Cryoquip was selected for this contract because of its record for high quality fabrication of gas skids within budget and on time.

Designing and fabricating industrial gas handling skids is one of the most challenging elements of the manufacturing process. Typical gases we deal with include nitrogen, oxygen, argon and hydrogen. Fully automatic PSA systems are manufactured either from customer prints or engineered and manufactured from customer P&ID's. Units can be manufactured in all common engineering materials, carbon steel, stainless steel or Aluminum.
