Modernization of ammonia synthesis reactors – application of INS-27C interior parts

  • Reactor efficiency: up to 600 t NH3/d.
  • Economical results:
    • reduction of energy consumption by about 65 kWh/t NH3,
    • reduction of hydrogen consumption by about 10 Nm3/t NH3,
    • increase of production capacity by 13-16%.
  • Replacement of reactor’s basket, without major modifications in the external pressure vessel.
  • Simple catalyst charge and replacement of catalyst load due to segment construction of the basket.
  • Possibility of application of fine grained catalyst(1,5-3 mm) with a simultaneous reduction in pressure drops: electric start-up heater placed in the basket axis.

Pressure disinsectization of plant raw materials with carbon dioxide

  • The method involves the creation of oxygen-free pressure atmosphere (carbon dioxide) and use of the effect of fast atmosphere decompression. It is an alternative method to the disinfestation of plant raw materials with the application of poisonous chemical compounds (methyl bromide, phosphine, ethylene oxide and others).
  • Process parameters:
    • pressure: up to 20 bars,
    • time of exposure: 1 ÷ 2 h,
    • decompression rate: 5 bars/min.

Supercritical extraction of plant raw materials with carbon dioxide

Supercritical extraction (SFE) with the use of carbon dioxide is intended for obtaining extracts from plant raw materials. Carbon dioxide is a completely inflammable and non-toxic gas. Its low critical parameters make it the perfect medium for the extraction of precious plant raw materials. Dissolving the various substances can be controlled by changing the process parameters. Traditional extraction methods in the solid-liquid system do not provide this opportunity. Adding a small amount of water or organic solvents such as methanol, ethanol, acetone, acetonitrile, ethyl ether, dichloromethane to carbon dioxide also allows for the extraction of polar compounds such as phenols, alkaloids or glycosides.
