Successful Commissioning of the Nitrogen Regeneration Loop Gas Dryer at Bandar-Abbas Refinery

Successful Commissioning of the Nitrogen Regeneration Loop Gas Dryer at Bandar-Abbas Refinery

For the first time in the country, Havayar designed, fabricated, and commissioned a Nitrogen Regeneration Loop Gas Dryer with a discharge of 12500 kg/h and a pressure of 4.5 bar at Bandar-Abbas Gasoline Refinery.

It is worth mentioning that this dryer has been designed and fabricated on the basis of a design attributed to AXENS, relying on the existing knowledge and experience of Havayar Corporation.
The main components of this package are as follows:
  • Towers with a capacity of 14000 L made of carbon steel
  • Sea water cooler made of S.S. 316
  • Steam heater made of carbon steel
  • 8-inch piping for wet gas line made of S.S. 316
  • Separator and demister made of S.S. 316
  • Siemens S-7 400 H control system
  • Anti-explosion instrumentation
The engineering, supply and fabrication phase of this dryer began in 2012 and ended in 2013.

From 2013 to 2014, the aforementioned unit was installed at Bandar-Abbas Refinery, but since the site was not available, the commissioning was postponed until early this year. Fortunately, in spite of the complexity of the process, the commissioning was realized in the shortest possible time. This brilliant accomplishment reflects the precision applied in all design, fabrication and monitoring processes for the installation and commissioning of the equipment, which is honorably the fruit of our expert staff’s efforts in all divisions.

This dryer has already been operating in the refinery's production line for more than 2 months, and due to this, the reduction process of CCR-line catalysts has become possible and the production of Euro 5 gasoline has begun at the refinery.
