The RAD Generating Plants are based on combustion of various
fossil fuels such as diesel oil, kerosene or natural gas.
The plant can also be based on the flue gas of boiler, turbines,
combustion engines, also from the natural sources, which contains
appropriate amount of CO2 contents. All plants are supplied
with the latest international technology and equipments and
the CO2 gas produced meets the best international standards
applicable for food grade quality or industrial use. All the
plants supplied mounted on skids for ease of installation
and commissioning at site. The plants are controlled by a
user friendly PLC based control panel and advanced automatic
instruments which result into continuous and trouble free
operation of the plant. Capacities ranging from 70 kg/hr to
standard 150 kg/hr, 250 kg/hr, 285 kg/hr, 500 kg/hr, 1000
kg/hr, 1250 kg/hr & more can be provided. Options of multifuel
usage can also be provided. The major components/process of
the generation plants are as follows:
chamber or Reboiler: The fossil fuels are burnt here in
the tubes and the rich mea is heated in the shell generating
steam for stripping of the CO2 gas from the rich MEA (Monoethanolamine)
solution in the stripper. For CO2 extraction plant units the
reboiler is not required and the heating of the lean MEA is
carried out with the help of steam heat exchanger. Shell is
of boiler quality steel with Stainless Steel tubes.
gas DCC tower: Stainless Steel tower where the flue gas
is washed and cooled in direct contact with water. If impurities
such as Sulphur Dioxide are present they are removed by adding
soda solution to water.
The CO2 contents of the flue gas are absorbed in the MEA solution.
The balance of the flue gas is vented into the atmosphere.
This is in Carbon Steel
solution heat exchanger: The MEA solution heat exchanger
preheats the Rich MEA solution with the lean MEA solution.
The preheated rich MEA solution is then passed on to the stripper
column. The lean MEA solution is then passed on to the Absorber
tower after cooling it again with water. Plates are in Stainless
In the stripper the CO2 rich MEA solution is heated and stripped
for CO2 .
Train : Stainless Steel Towers which removes the impurities
such as NO x, aldehydes, smell causing impurities and other
Compressor: The non lubricated CO2 compressor compresses
the CO2 gas from atmospheric pressure to 15
20 bar in
pressure precooler and Dehydrator
The CO2 gas is cooled to a temperature of 4-15 degree C and
after a moisture separator to the dehydrator which removes
the moisture to a level of 10 ppm. SS Precooler with boiler
quality steel for Dehydrator.
The refrigeration unit cools and liquefy the CO2 at a temperature
of (-) 25 degree C.
The liquid CO2 is stored in an insulated storage tank at a
pressure of 15-17 bar and a temperature of (-)25 degreec C.Choice
of Horizontal & Vertical tanks made out of boiler quality
normalised plates for low temperatures inspected under third
party BVQI, Lloyds or DNV. Tank fitted with safety valves,
load cells & other accesories.
Optional Accesories like Cylinder filling, Dry Ice or Vaporisers
are all supplied depending upon the usage.
