Cement companies to explore the application of CO2 resources

Temperatures up to 880 percent, reduced CO has reached the required Nco temperature, so the decomposition of carbon reduction furnace with CO is feasible. Theoretically, according to chemical formula (2), carbon reduction 46.2tCO need 12.6t produce 58.8tCO. If coal will be out of all the CO calciner reduced to CO, you need to 23.3t coal. If a single coal preparation 58.8tCO, you need to consider 46.7t coal volatile coal and the system heat balance,[link widoczny dla zalogowanych], the actual amount of coal consumed and the amount of CO produced calciner and the final production of the volume over the previous 23.4t15.2r CO ------] I into l,[link widoczny dla zalogowanych], \1 Levin cement 2400t / d clinker line access and circulation of Co2 per hour above simplified calculation to a large. Gas impurities are mainly coal combustion air brought people to use nitrogen. calciner with a heat c0 gas as the least amount of preparation coal, reducing the use of the air. thus the amount of nitrogen with some people and less so with the decomposition of the gas furnace heat cO CO content of prepared coal preparation than a single high gas cO 4. clinker kiln decomposition process is currently clinker burning technology is relatively mature, the use of a calciner heat CO manufacturing gas technology does not expand the existing clinker process changes, process changes only in four aspects: First, the C part of the lead cylinder gas to the gas furnace; Second, not into the kiln gas cylinder C, but with three times the wind all the way, some of the C tube gas, adjust the convergence of cold air into the cylinder C: The third is three times the wind in three columns, all the way into the calciner. all the way and kiln gases, a gas cylinder C, adjust the convergence of cold air into the C tube. all the way to convergence with the C into the gas cylinder gas furnace; fourth is added into the C tube cold air conditioning duct mouth of the C cylinder gas should be diverted to the gas most of the preparation system. kiln preheater system is inadequate air flow, mainly through the tertiary air and kiln gases to supplement. As the tertiary air and kiln gas temperatures are high, so the need to use cold air to regulate. to ensure that the C barrel temperature to meet the process requirements. from C C cylinder tube into the wind. preheating kiln system needs to be based on air volume, air temperature and the gas preparation system to adjust production. calciner in order to reduce the ventilation pressure. design all the way around the calciner tertiary air tube outlet gas with C merging into the gas furnace. calciner heat by the gas after CO manufacturing, cement clinker burning process shown in Figure 2 Figure 2 using the decomposition of CO gas heat furnace clinker preparation of gas preparation process diagram 5 the normal gas case, the decomposition furnace gas mixture in the C tube material to be separated. raw materials were kiln. gas into the gas cylinder preparation system, and C4. most of the C should be able to get the gas cylinder gas preparation system, used to prepare the gas. in the gas in the furnace. from coal kiln preheated hot air will reach the required temperature reduction of CO, while part of the incomplete combustion of coal produces CO. from the CO cylinder C and thermal coal in the reduction of carbon in the reaction of CO. gas from the furnace, after a series of purification, separation given away after the chemical production process. or temporarily sent to the gas tank. separated from the exhaust gas back to the kiln for clinker. 6 annual benefit assessment 750,000 t of clinker kiln with coal chemical decomposition of co-generation production lines, such as a calciner heat the gas to be fully used to prepare gas,[link widoczny dla zalogowanych], coal can be saved per year by 175,500 t. 600 per tonne of coal to the factory price element. coal cost 100 million yuan can be saved. Enterprises to the atmosphere per year CO234.65 knife t. 7 build cement CO, the application of resources for eco-industrial organic chemical industry. CO is a very important basic raw material gas. It can be into hydrocarbons. and then further transformed into other organic products. coal chemical business investment is often much greater than the investment in cement companies. Therefore cement application of CO resource model should be based on the coal chemical production process of cement. practice of coal Chemical and cement generation. using heat generated during cement calcination CO gas preparation, and then further transformed into hydrocarbons and other organic industrial products. In this mode,[link widoczny dla zalogowanych], the establishment of cross-over industry. from the cement production of CO, coal, chemical production, directly or indirectly by CO as a raw material, the existence of the question, they close the supply relationship. 8 Conclusion CO application resources cement not only reduces CO: emissions, while coal chemical and cement enterprises for efficient integration. saving coal consumption. comply with national environmental policies and industrial policies. cement CO, the application of resources is only our proposal, would like to draw attention to the relevant departments. factory] 2007.4CHlNACEMENT69
