Oil & Gas : Europhtal catalysts for mercaptan treatment

For more than 20 years, the brand Europhtal has been known for the mercaptan oxidation process inside sweetening units.

In order to comply with the different international standards for total sulfur content and mercaptan presence in the production of LPG, Naphtha or Kerosene, Europthal developed a full range of catalysts depending on the application.

Two types of catalytic units  (extractive and sweetening) can be used.

Global oxydation chemical reaction  in a reactor : 

4 RSH + O2 < == > 2 RSSR + 2H2O

 

We have two types of catalysts for mercaptan treatment :

  • mercaptan extraction (liquid / liquid extractive process) : liquid catalyst
  • mercaptan transformation (fixed bed process): solid catalyst (pre-impregnated charcoal)

Mercaptan extraction

 

Europhtal catalysts, dedicated to mercaptan extraction, run on a liquid/liquid reaction for butane, propane, GPL and light straight-run gasoline.

We have 2 products for mercaptan extraction :

Quality commitment

 

In order to confirm the efficiency of our catalysts for mercaptan treatment, Quadrimex Chemical pays attention to control all the critical stages of the process :

  • Selection of the catalyst and optimal formulation
  • Selection of the adapted charcoal for a perfect impregnation

All these control steps are managed by our engineering service in our laboratory, located in our offices in France.  

Thanks to our expertise, we provide technical support to our customers in order to :

  • Optimize the consumption of catalysts
  • Improve reaction parameters (air supply, temperature…)
  • Produce sweetening efficiency reports
