The biological procedures and burning along with fermentation, digestion and decomposition reaction of organic material results to the establishment of carbon dioxide plants. It unites with water in atmosphere to form carbonic acid which rusts marble, limestone and metals. The denseness of carbon dioxide in atmosphere is not eminent enough to make it commercially recoverable as a product. Commercial production rests upon splitting up and sanctifying CO2-rich gases which are produced by combustion or biological processes. If these gases would not be recovered, they would vanish in the atmosphere. This is the reason why the commercial CO2 is largely found as by-product of other processes.
Biomass as a boon for CO2 extraction
SS Gas Labs Asia is working on technology of drawing out CO2 from biomasses. Our company was the first to introduce this technology in this world. Today we have set up various gas plants that successfully operate on biomass. While working on this technology, we are invariably figuring out design inventions of its plant grounded on fertilizer gases, industrial plant and distilleries to draw out even more wealth from waste material. The biomass gas plants can be designed in various capacities ranging from 30kg per hour to 2000kg per hour based upon the usable stimulus and client requirements.
Purest source of CO2
The Biomass gas plants are configured to utilize industrial by-products as their crude materials, which functions as a blessing for distilleries and breweries where soured gases are acquired in mass and differently would go waste. We retrieve odor-free CO2 with the use of these plants. The bio-gas plants themselves are 100 % pollution free causing no ecological instabilities, rather they absorb CO2 which otherwise would have been unified with the environment. These gas plants are cost-effective in running apart from investment needed to establish the plant.
Other sources of CO2
As already mentioned, SS GasLabs Asia's CO2 plants produce CO2 from Biomass, which is actually wastes recovered from many sources. Majority of gas for CO2 use the following sources:
Generating plants are grounded on various fossil fuels combustion including kerosene, diesel oil or natural gas. The CO2 gas plants conform to the most rigid CO2 quality standards, done by appropriate fuel combustion, stripping, scrubbing and breakup technology. CO2 gas plant is supplied with an exceptional instrument panel that ensures uninterrupted and problem-free functionality. All equipments installed on the slides are cabled to junction boxes anterior to loading cutting down commissioning and installation time on site.
The CO2 Recovery plants operate as screening base to the inventions that we have formulated in the recent period. We make sure of the functioning level of the procedure before availing them commercially to the clients. We, ourselves, are running CO2 plant also and hence we can understand the virtual problem that may come in running the plant. So we can easily address them right away as soon as any such issues comes up with our customer.
CO2 extraction plants are founded on the presence of CO2 in the gas sources from chemical processes , combustion engines, boilers and turbines and natural sources. A CO2 extraction plant proves an efficacious substitute for a conventional CO2 production plant, where an subsisting raw gas source with a comparatively low CO2 content is available.
Enhanced Oil Recovery : A well is a very big hole dug in the ground. Sometimes it contains water, some times it contains oil and sometimes it has got Carbon-Di-Oxide gas mixed with water. The oil wells turn to give sub normal output, after its continuous use. The Carbon-Di-Oxide injection helps in recovery of more oil from the well. The addition of Carbon-Di-Oxide gas through injection (of gas) some times gives extra oil by about 30-40%.
The injection of Carbon-Di-Oxide does the following :
Since the quantity of C02 used in the wells is considerable and hence one can be sure of getting.
Carbon Credits : The oil well can be used for storing C02 or we can say underground disposal of C02. This gives rise to possibility of use of C02 at a latter period when we wish. Thus this fulfills dual role of increasing oil production and storing C02 & definitely we can dispose of carbon now each carbon credits.
There are many examples in the world to obtain Carbon-Di-Oxide from various sources and to carry and use Carbon-Di-Oxide on the well head, for better recovery of oil.
CO2 from Chemical Reactions : Many a time one has the requirement not to fill the big cylinders from the storage tank but to fill small cylinder / C02 extinguishers / cartridge from big cylinders. In such eventuality the revert gas is not important as the quantities concerned is not big. What is needed is accurately that the liquid goes into a small cylinder and semi automatically / automatically switched off the supply, as soon as the required quantity is filled in the small cylinder.
S. S. Gas Lab Asia, Delhi is now dealing with such a installation. Following illustration clearly shows the system :-
The complete unit consists of a motor driven transfer pump, an optional for 27 kg supply cylinders and the necessary hose arrangements and valves to connect the pump to the supply and the necessary liquid must be supplied to the pump. If the supply cylinder valve connects into the vapor spare of the cylinder, the cylinder must be turned bottom up. The tilt rack serves this purpose. If the supply cylinder is of siphon type then the rack is not required. Such cylinder must be tied securely to a wall or post.
The weighing scale is also included in the system. We are in the process of developing automatic system which enables to switch off the supply of C02 once the small cylinder has been filled with the desired quantity of the gas.
Bio Gas can be generated from various sources. The material should not contain metal, sand, mitti, stone and polythene etc. Cow dung besides others like kitchen / canteen kachra is used extensively in India. Feas from birds like cocks and hens are used in some countries.
All sources almost go to generate biogas in the generator where it is generally mixed with water. The reaction to generate biogas takes place quickly in summer and some what slowly in winter. Generally, the biogas is associated with H2S and consists of C02 and CH4.
H2S must be removed to use the gas chemically. Many people use the gas as it is in the power generation or for cooking. H2S is removed with the help of scrubbing media placed inside a scrubber. Generally, the biogas contains 55 - 70% CH4 30-45% C02, 0.1 - 0.5% H2S and traces of Hydrogen and ammonia. We have the technology to remove H2S and C02, get pure 98% CH4.
