Combined Gassing

For Gas-Liquid Reactions with Pure Gases

An agitator system of EKATO PHASEJET and EKATO GASJET combines high gas rate dispersion with the internal gas recirculation. The excellent mass transfer enables quick and complete utilization of process gas. No external recirculation equipment is required. The EKATO combined gassing system boosts the conversion of mass transfer limited reactions. Unconverted gas in the headspace is recirculated into the reaction media leading to a complete utilization of the reaction gas.

The Challenge

Reactions using purified gases call for

  • Complete utilization of the gas
  • High productivity through a shorter reaction time
  • Reliable containment of the gas and the products of reaction

The EKATO Solution

High productivity in a simply constructed reactor with the EKATO combined gassing system

  • Combined action of two different impeller types
  • Primary dispersion by the EKATO PHASEJET
  • Recirculation by the EKATO GASJET
  • Low concentrations of feedstock in the reactor due to high local rates of chemical conversion and short mixing times

The EKATO GASJET

  • Recirculation of reactant gas from the headspace with no external compressor
  • Intensive mixing of feedstock and reactant gas in the impeller discharge zone
  • High heat transfer rates

What does “Number of sealing faces” mean?

Single-acting mechanical seals
These seals have one sealing surface and only seal in one direction. They are generally simpler in design and are commonly used in applications where pressure is applied from only one side.

Double-acting mechanical seals
These seals have two sealing surfaces and can seal in both directions. They are ideal for applications where pressure may come from both sides or where a higher sealing performance is required.

Triple-acting mechanical seals
These are less common and used in specialized applications that require a more complex sealing setup. They offer additional sealing surfaces or mechanisms to ensure reliable sealing even in highly demanding environments.
