Recuperative Oxidizer Replaces Catalytic RTO for Boat Engine Manufacturer

The Challenge

A major Boat Engine manufacturer needed to lower emissions from engine cell testing. All of their motors, whether were Pre-Tested for several hours prior to shipping. The emissions from these Engine Cells were mostly Carbon Monoxide and unburned fuel, with particulate.

The company currently had a  catalytic oxidizer installed, but was not very happy with its performance or the cost of the catalyst. They had problems with frequent replacement of the catalysts, including catalyst fouling and catalyst masking.

The Solution

Epcon evaluated several technologies.  Because of the technical superiority of the Recuperative Oxidizer, it made great sense to use Recuperative Oxidizers rather than RTO or Catalytic system and the Catalytic technology was eliminated.

Factory Acceptance Testing was conducted with fuel-rich conditions, to ensure the system met all requirements. Epcon has built several systems for Boat Manufacturers and each application is carefully analyzed  for the specific particulate and for the CO.

The Results

The Recuperative Thermal Oxidizer not only eliminated the hassle and high cost of catalyst, but also increased the DRE by 2% while keeping the facility in compliance.

On an ongoing basis, Epcon provides Preventive Maintenance Service to the customer and the system has been operating very successfully!
