Bengal Gas Engineering&Service

Our clients can avail from us highly functional Ammonia Cracker that is a type of ammonia gas generator. It produces a mixture of Hydrogen and Nitrogen that are used in heat treatment furnaces. The functioning of the machine is explained below:

• Ammonia cracking reaction is endothermic in nature, so it requires heating from outside
• Ammonia cracking takes place on Nickel catalyst at high temperature of 850°C
• The cracked Ammonia gas contains around 100-ppm uncracked ammonia impurity
• Dew point is only (-) 30°C

The key features of our product are given below:

• Production capacity: Up to 100Nm³/hr
• Provided with electrical heating furnace
• Low maintenance
• Compact design
• Easy to operate

The various applications of our product are as follows:

• Medical applications
• Chemical industry
• Refrigeration

We offer Endo Gas Generators that are used to produce endothermic gas by the reaction of air and LPG at a high temperature of 1050°C. The catalyst used for the reaction is Nickel. Our product comprises mixing unit, cracking retort, and control panel. The heating of the retort is affected by heating element it. The typical gas conditions are:

• CO2 - (0.1- 0.5) %
• CO - (28 - 30) %
• H2 - (20 - 25) %
• N2 - Balance
• Dew Point - 5°C

The key features of our product are:

• Have high capacity ranging from 5NM³/hr to 100 NM³/hr
• Fully automated
• Easy to install

We offer a wide range of Exo Gas Generators that includes Raw Exo- Gas type, Partially Dry Exo- Gas type, and Perfectly Dry Exo- Gas type. These are used for the heat treatment of non-ferrous metals like for scale-free annealing of brass and bright annealing of copper, and ensure complete cracking of the products of combustion. The various types of Exo-gas generators offered by us are explained in detail below:

• Raw Exo- Gas type: In this the products of combustion are directly used as protective gas
• Partially Dry Exo- Gas type: These are used where there is requirement of partial removal of moisture in order to prevent oxidation and decarburization. Hence, in this type, the gases are passed through a refrigeration unit, which enables reduction of the dew point to about + 5° C
• Perfectly Dry Exo- Gas type: In this, there is moisture free gas generation, which is followed by refrigeration unit, and then packaged in desiccant drier like alumina or silica gel

Technical specifications:

Lean Exo-gas is generated by combustion of fuels at slightly lower sub-stoichiometric combustion air to fuel ratio. The atmospheres ranging from 90% to 98% of perfect combustion have the following composition:

• CO: 0.5 to 1.5 %
• H2: 0.5 to 2 %
• N2: Balance
• CO2: 11 to 13 %
