Oil & Gas Worlda fast and secure degassing

Treatment of industrial air for the oil & gas industryWe are proposing 3 different technologies approaches for the degasing and/or recovery of VOC’s:

Catalytic oxidation

Special development for oil & gas, allowing high concentration, even chlorinated, coming from ships & tanks during degasing.


  • High security: DEKRA certified & ATEX for parts in contact with solvent. Redundancy in placed securities
  • No contact of solvant with direct flamme
  • No production of CO, no NOx, no SOx: only CO² and H²O
  • Follows automatically the flow and concentration variations, from 500 to 3.000 Nm³
  • Easy to implement, easy to move: delivered on a sea container form, you just have to plug energy & IN/OUT
  • Auto thermal already reached from… 0.75 gr. compared to the classical 3 to 4 gr. usually proposed
  • Vry low use costs; good to use with practically any type of solvents
  • Little place necessary
  • Results of Output registered in SIEMENS PLC (PID in chimney)
  • Remote protected access to all data’s of machine, allowing full remote assistance and/or following of treatment data’s on line
  • Fully modular: when needed, combined modules are able to cover more important flows to treat
  • Good longevity as material used (mostly Stainless steel 316L answering perfectly to sea atmosphere) and few moving parts
  • Energy recovered for electricity, cooling or heating when needed.
  • Combined with our cryogenic solution, allows to treat a bigger flow.

What is catalytic oxidation?

An efficient way to oxidize the solvent present in industrial emissions. Preheated air is passing between catalytic plates containing incrusted precious metal, such as platinum & Rhodium, sometimes Palladium An exothermic chemical reaction eliminate the solvent, transforming it into H2O, CO2 & heat. Recovered heat will then be used, partially to preheat incoming air; then to use in customer’s production under 3 forms: heat (vapor, diathermic oil …), cold (reaction with lithium Bromide: can cool water up to 7 to 10°C all the year), or electricity. The available energy is important, as we don’t need a lot of heat to preheat incoming air. To oxidize, we are not obliged to heat up to 850°C, as thermic oxidizers: we need only 300 to 450°C for the same result, and without creating secondary pollution. Therefore, the autotherm situation is easy reached and hold. Gas consumption will be ridiculous, generally limited to the pilot flame. This machine react automatically to fluctuation or/and concentration of airflows and adapt the flow output consequently. This system, which present the advantage to not have open flame, is fully modular, allowing to synchronize, if wanted, more modules to increase the flow to be treated. A module will automatically stop if it is not necessary.The preheating chamber is very small, so the heat is kept during hours without any problems.

Patent system


Our cryogenic solutions are able to treat polluted airflows up to 1.500 Nm³/h with or without liquid nitrogen, condensing the VOC’s with A GARANTEED NITROGEN CONSUMPTION OF 15 to 20 Liters /HOUR. This machine, offering such a solution usually applied for condensing VOC’s with boiling points under the -40°C (-40°F), offers under more the possibility, thanks to its world patented system lowering, without use of nitrogen, the temperature of an incoming gas of +- 70°C (- 94°F) bringing an incoming air of 20°C (68°F) to+-45°to -50°C (- 49° to -58°F).


  • Secure system (no flame), as DEKRA authorized and ATEX for parts in contact with solvents (on complete machine on demand). Redundancy in placed securities
  • Multiple applications, with use of liquid nitrogen or without nitrogen, and airflow from 500 to 1500 in direct treatment. – Very low nitrogen consumption when needed, as multiple heat exchanger has been used, and our capacity to lower temperature without nitrogen
  • Full automatic system adapting itself to flow and concentration variations, from 500 or less to 1500 Nm³/h.
  • Easy to implement and to move, as it is delivered in a sea container form (+- 7 x 2.3 x 2.4 m)

This technique allows three interesting approaches for the degasing:

  • Direct treatment, with nitrogen
  • Combined with our catalytic solution, the cryogen allows a first efficient abatement of the heavy gasses before entering to the catalyst, increasing the possible concentration of the gases to be treated: No need of nitrogen for this application
  • Cooling the gases flow before entering into active coal filters increases its efficiency: No need of nitrogen for this application

Our cryogenic solutions

  • Cryo technology without nitrogen:
  • Small units used to optimize activated coal (or zeolite) filters by lowering the temperature of the airflow to be treated
  • Cryo technology with liquid nitrogen:
    • Small unit used to clean small LPG tanks
    • Recovery of fuel when filling trucks or ships
    • Degassing of tanks & ships.

Regenerable activated carbon (or zeolite) filter

An interesting solution when concentration is low. Filters are desorbed in +-2 to 4 hours (depending on the size of the chosen filters. Desorption happens in closed loop, together with a small catalytic oxidation unit specially adapted for it. The desorption happens practically constantly in auto thermal situation The longevity of active coal is increased, as the air t° is regulated to enter the filter, and coal is not moved nor transported anymore. Recovery of temperature is used to preheat incoming air.


  • Security: Dekra certified, build following ATEX norms with oriented explosion walls.
  • Easy to implement and not expensive; allows to manage the weak concentrations.
  • If more than one filter connected, the saturated filter is automatically disconnected and replaced by another up to its cleaning
  • Filters pre equipped with PID allowing control of airflow quality. Results registered in PLC of catalytic oxidation unit.



Light solvent concentration

  • For light concentrations (recovery of tanks or/and pipelines breathing gasses), a heavy installation is not necessary.
  • We are therefore proposing regenerable activated coal (or better: zeolite) filters. Those filters can be regenerated by our small catalytic oxidisers in +- 2 – 4 hours (depending on the size of the filters).
  • Saturation is automatically detected, and switching happens automatically. The switch with other clean filters when saturated can happen automatically with other clean filters present on the skid.
  • Regeneration can also start automatically
