 MGS
Ammonia Cracking Units or Ammonia Cracker Gas Generator produces
mixture of Hydrogen and Nitrogen by cracking Ammonia, which takes place
in presence of Nickel catalyst at
850°C temperature.
Ammonia Cracking Units / Ammonia Crackers
MGS Ammonia Cracking Units or Ammonia Crackers are fully automatic,
easily operational and are virtually maintenance free .
In addition they have a compact body and can be installed very
close to PSA Nitrogen generation equipment. The cost of Hydrogen
generation by this method comes to around Rs.4.00 per Cubic
Meter only.
Ammonia Crackers are very simple units. They are widely used in
industries for small generation of Hydrogen gas. Ammonia
Cracking Units are electrically heated units which consume
around 1.4KW power per Cubic Meter of Hydrogen. Raw material for
these units is Ammonia gas which is easily available in standard 60kgs capacity cylinders
in open market. When Ammonia gas is passed over Nickel catalyst in
these units, it cracks into N2 + H2 mixture containing 75%
Hydrogen and 25% Nitrogen. This mixture is used as Deoxo Purification Unit for
Oxygen removal.
FOR GETTING PURE HYDROGEN
If pure Hydrogen gas of 99.99% purity is
required, a PSA Molecular sieves unit after these
Ammonia crackers is provided ,which removes Nitrogen. This PSA unit operates
at 7kg/cm²g pressure and produces pure Hydrogen gas at 5.5kg/cm²
pressure. This type of ammonia based hydrogen generator is very
economical up to 50 Nm³/hr Hydrogen
capacity.
MOLECULAR SIEVES PURIFIER
A Molecular sieve purifier is provided after
Ammonia cracking unit for reducing residual ammonia content and to
get very dry gas. This reduces ammonia down to 1-ppm level
and dries gas up to (-) 80°C dew point.
