Oxygen enrichment is a low-risk, high-return and short-payback solution to today’s refinery bottlenecking problems, according to a new white paper prepared by Linde LLC.

With oxygen enrichment, Linde offers an innovative approach to enhancing furnace performance and reducing nitrogen oxide emissions without requiring high capital expenditure (CAPEX).

The white paper, Improving process efficiency in refineries with oxygen enrichment - Focus on fired heater performance, is available as a free download on Linde’s website.

Linde North America is a member of The Linde Group, a world leading gases and engineering company. Based on Linde’s decades of proven experience in oxygen enrichment technology, the white paper discusses how oxygen enrichment can help increase the efficiency of refinery operations while enhancing its overall environmental performance.

“Given the cost, high risk and long downtime associated with upgrades, many refinery operators are looking for a more flexible, low-CAPEX solution,” said Bob D’Orazio, program manager, Chemical Segment for Linde LLC, and one of the authors of the paper.

“Oxygen enrichment is a low-CAPEX, reversible solution that is the ideal strategy for a low-risk, high-return and short-payback route to enhanced furnace operations.”

Linde’s new low-level oxygen enrichment solution, for example, is tailored specifically to the needs of fired heaters. By modifying the burner design, this technology increases the efficiency, capacity and lifecycle of furnaces. At enrichment levels of less than 28%, oxygen can also increase the performance of optimized systems even further. Some of the potential benefits include:

  • · Up to 45% reduction in NOx emissions relative to air-only combustion
  • · Up to 5% increase in efficiency levels
  • · Low CAPEX solution
