Where do you use the waste gas emitted by fertilizer factories?
Thread Content
In the production of synthetic ammonia, large amounts of waste gas are emitted, including significant quantities of CO2 and various other polluting gases such as sulfur-containing gases. Among these, CO2 contains the highest amount of carbon; through simple washing and separation processes, its purity can be increased to 97%. CO2 has a wide range of applications, including in welding, the food industry, and greenhouses. Wouldn’t it be great if we could purify it and use it in industrial and food-related applications? This way, we could avoid environmental pollution while also generating profits. I’m curious – how is waste gas handled in your factories? QQ: 50835115.
CO2 is purified and used in industry and food production: lol
Purify, separate out, and sell.
Generally, it ends up in the atmosphere.
It’s a waste to release it into the atmosphere; it also contributes to the greenhouse effect. I think it would be better to purify it for industrial use, or to further process it for use in food products. Our factory specializes in producing products for food use
After purifying CO2, it is sold as liquid carbon dioxide for use in the food industry; the rest is vented, and the ammonia and hydrogen components are recovered. These are then burned along with the gas generation air to produce steam, and that’s basically it
The views expressed on the 7th floor are quite reasonable. Especially these days, CO2 is widely used in both gas and liquid forms; it would be a shame to simply release it into the atmosphere. I hope those working in the fertilizer industry will pay attention to environmental protection, improve corporate efficiency, and actively develop methods for purifying and liquefying CO2 derived from fertilizers, in order to reduce the emission of polluted gases.
The main waste gases are generated in the flue gas from the first-stage furnace combustion; currently, the treatment method for these gases involves reducing their temperature to minimize thermal pollution, and of course, to save energy as well. Some companies with insufficient CO2 have carried out the recovery of CO2 from flue gas. However, due to low concentration, numerous impurities, and the presence of sulfur, nitrate, etc., the treatment costs are high. In fact, the CO2 emissions are not very high either; the total amount of greenhouse gases is comparable to the greenhouse gas equivalent emitted by small nitric acid plants.
Carbon dioxide can generally be used as a raw material for urea production! You can also use pressure to extinguish a fire extinguisher! Hubei Shuanghuan Chemical sells carbon dioxide to Coca-Cola!
Our factory is a joint venture with Linde Gas to produce food-grade CO2.!!
Our company utilizes Tianyi technology to produce food-grade liquid carbon dioxide through PSA decarburization and adsorption, which is then sold. All operations are automated. It’s just that obtaining the safety production license, production license, and health license is a bit troublesome.
Each factory can conduct a market survey based on its location, the amount of CO2 remaining, as well as the regional demand for and production capacity of food-grade CO2. Since one does not have the funds or capabilities to handle things on their own, it is a good option to reach out to international companies such as Praxair and Air Liquide for cooperation – it is environmentally friendly, cost-effective, and requires no out-of-pocket expenses
Which factory generates carbon dioxide in its ammonia synthesis process? :The waste gases generated during the ammonia synthesis process are hydrogen, nitrogen, ammonia, etc. These waste gases are produced to prevent the accumulation of inert gases in the ammonia synthesis system; the inert gases mainly include argon, carbon monoxide, carbon dioxide, etc., but their concentrations are very low! Hydrogen and ammonia in exhaust gases can be burned and used as gas!
