Large Capacity Hydrogenators / High Mass Transfer Area Reactors


Nano-Mag make High Mass Transfer Area Reactors Hydrogenators are specially designed for various Gas-Liquid reactions. These large scale reaction vessels are robustly built for longer life and to withstand constantly varying temperatures and pressures due to internal reaction conditions. These gas induction reactors are fitted with specially designed Agitator which creates very high gas-liquid contact area by recirculation of headspace gases, leading to superior mass transfer rates. Agitator is available with two sealing options such as Mechanical Seal & Magdrive.

Along with Hydrogenators, we offer different accessories like flameproof control panel, rupture disc, safety relief valve, automatic pressure & temperature controllers, PID controlled DM water cooling system for exotherm removal etc. These high volume reactors are used in various gas liquid reactions with gases like Hydrogen, Ethylene Oxide, Ammonia, Oxygen, HCL, Phosgene, CO₂, CO, Air etc. We have successfully installed large number of gas-liquid reactors and hydrogenators. Our design and engineering abilities, combined with our fabrication and machining facilities allow us to manufacture custom made reactors for most critical applications. Contact us to find a best solution for your requirement of commercial scale reactors.

Advantages & Benefits

  • High Mass Transfer Area: Self-operating impeller recirculates headspace gases through hollow shaft. The impeller disperses the gas vigorously in the liquid column resulting in very high gas-liquid interfacial area
  • Faster Reaction: High mass transfer area leads to faster reactions
  • Shorter Batch Time: Faster rate of reaction leads to shorter batch time
  • Lesser Catalyst Loading: Very high gas-liquid interfacial area ensures that excess catalyst loading is avoided
  • Minimum impurities: Shorter batch time ensures that there are no unwanted side reactions.
  • Higher yields: Less impurity ensures highest possible yields
  • Better Product Economy: Shorter batch time, optimum catalyst usage and highest yields ensure best product economy


  • Hydrogenator capacities from 50 ml to 50kl
  • Pressure range from full vacuum to 350 bar
  • Temperature range from cryogenic to 600°C
  • Different material of constructions like SS 316, SS 316L, Hastelloy C, Zirconium, Inconel, Monel, Titanium, Nickel etc.
  • Conforming to international standards CE, PED, ASME, ATEX etc.
  • Explosion bended cladding options for cost effective design
