Oxygen Gas Plants/Nitrogen
Gas Plants:
The oxygen production plants and nitrogen production plants are safe and
economical & operate with an expansion engine which lowers the operating
pressure upto 30-40 kg/cm², lowers the power consumption and is trouble
free. The plant mainly consists of AIR COMPRESSOR molecular sieve battery
for removal of acetylene and hydrocarboxes from the process air and
eliminating the use of caustic soda and cost saving as there is no need of
any recurring cost of chemicals. The plant can produce both OXYGEN &
NITROGEN simultaneously and the plant BDM models have a Built-in internal
compression liquid oxygen pump to fill bone dry high pressure oxygen upto
165 kg/cm² in cylinders.
Salient Features
- Very simple to operate
- No raw material is required
- Trouble free operation for years (German design)
- Easy availability of spare parts
- Low power consumption
- Production of oxygen & nitrogen simultaneously without use of
bulky gas holders.
- Latest molecular sieve technology without recurring cost of
chemicals
- Industrial & Medical Oxygen

Process Description of BDM Oxygen Plant
The free atmospheric air is sucked in by a multi-stage air compressor
through a filter and compressed to the working pressure. After each stage,
intermediate coolers and water separators are provided. The compressed air
then passed through the evaporation pre-cooler and then to the molecular
sieve battery where the moisture and carbon di-oxide are removed from the
process air. It then passes through the heat exchanger No.1 where it is
cooled by the out-going waste nitrogen and product oxygen.
A part of this cold air then flows through an expansion machine and the
balance through the 2nd heat exchanger. The ratio of the two air streams is
controlled by an expansion valve, RI. Both these streams of air then unite
in the medium pressure column where it partially liquefies.
The liquid air (rich liquid) then passes through the expansion valve R2 to
upper column which is at lower pressure then the medium pressure column.
Similarly the liquid nitrogen (poor liquid) travels from the medium pressure
column to the upper column through an expansion valve R3 where the
separation of oxygen and nitrogen occurs. Nitrogen being more volatile
passes out as a gas from the top of the column and this waste nitrogen flows
through both the heat exchangers cooling the in-coming air. Similarly the
product oxygen is also passed through the two heat exchangers to cool the
incoming air and then to the filling manifold via a liquid pump.

Acetylene Gas
Plant:
Features of Acetylene
Acetylene (C2H2), a compound of carbon and hydrogen, is a colorless, highly
flammable gas. It is slightly lighter than air and has a garlic-like odor.
Acetylene is stored in high pressure cylinders filled with a porous material
and containing acetone, into which the acetylene is dissolved. Unless
dissolved in a solvent, acetylene will dissociate at pressures above 15 psig
and form lamp black and hydrogen. Heat is generated with dissociation, which
in turn, produces a danger of explosion.
Acetylene is manufactured by the reaction of water with calcium carbide. It
is also manufactured by thermal cracking of hydrocarbons, or by partial
combustion of methane and oxygen.
Acetylene has become increasingly prominent as a raw material for a whole
series of organic compounds, among them acetaldehyde, acetic gas, and acetic
anhydride. The remaining 20% of the acetylene production is principally used
for oxy-acetylene cutting, heat treating, and welding.
Our BDM acetylene plant is highly versatile and designed and manufactured
by experienced and qualified Engineers. All the parts are made with the best
materials as per drawings with complete inspection and quality control.
The Acelytene plant is highly safe and dependable and is FULLY AUTOMATIC
and are available in models BDM 45 & BDM 100 in sizes of 45 & 100 m³/hr.
All the operations are automatic and performed by imported pneumatically
controlled valves assisted by highly sensitive senssors alongwith the
temperature controlled instruments. The entire plant is designed with utmost
safety in mind alongwith flash back arrestors, High pressure reverse flow
check valves and complete help to protect both the equipements and the
operators.
