CAMOL™  Catalytically-Assisted Manufacture of OLefins

CAMOL™ Catalytic Coatings

CAMOL™ advanced catalytic coatings are applied on the internal surfaces of steam cracker furnace tubes and fittings used to manufacture furnace coils, enabling the catalytically-assisted manufacture of olefins.

Why use CAMOL™?

Uncoated furnace tubes coke at significant rates depending on feedstock and operating severity.  CAMOL™ decreases coking rates due to its inertness to filamentous coke-make and its ability to gasify amorphous coke.

What are the benefits of CAMOL™ catalytic coatings?

The coatings improve operational profitability of steam cracker furnaces by reducing carbon formation, increasing on-line production time, and reducing decoke frequency, energy requirements and GHG emissions.

What are the applications for CAMOL™?

CAMOL™ catalytic coatings are applied to meet the needs of different furnace designs, feedstocks, and operating conditions.  CAMOL™ is available at two gasification coating capacities: (1) a Low-Catalytic Gasifier (LCG); and (2) a High-Catalytic Gasifier (HCG), both inert to filamentous (catalytic) coke-make.  The LCG coating can be used in lower amorphous (gas-phase) coking environments such as conventional ethane-propane cracking, while the HCG coating surface targets operating environments with higher amorphous coke-make found with cracking heavier feedstocks such as naphthas.  Both LCG and HCG coatings are commercially available and ideally suited for Medium severity cracking.

Performance of CAMOL™ Catalytic Coatings 

Delivering improved operational performance for steam cracker furnaces

With its unique ability as both an inert barrier and a gasifying catalyst, CAMOL™ enables improved operational efficiency.  This is realized by increasing on-line production time as well as significantly reducing energy requirements and GHG emissions. 

As an inert barrier - CAMOL™ protects the surface of the tubes by generating an inert barrier between the Fe and Ni in the base steel and the hydrocarbon feed.  The surface barrier is an oxide layer typically <10 microns in thickness, and can be repeatedly regenerated through normal operation.  The surface oxide is inert to filamentous (catalytic) coke-make.

As a gasifying catalyst - CAMOL™ provides a catalytic surface that gasifies coke precursors formed in the gas-phase (amorphous coke) and which would otherwise collect on the tube wall as coke into CO and/or CO₂, thus offering a two-pronged approach to address both catalytic (filamentous) and amorphous (gas-phase) coke.

Benefits field-demonstrated to-date:

1. Energy reduction:

  • 6.3% reduced energy via fuelgas

2. Environmental benefit:

  • 5.3% reduced carbon emissions via fuelgas

3. Coil life extended:

  • Previous coil life = 5 years
  • CAMOL™ coil life = 5.8 years

4. Minor yields improvement: (non-catalytic / due to operating conditions)

  • Minor increase in ethylene and propylene yield observed during naphtha feed test, presumably due to reduced pressure drop and higher heat transfer effects of CAMOL™.
