Which companies are already in use? Which ones are in pilot production? It’s not convenient for manufacturing companies to say so, but research institutions can talk about it; it can be considered as product promotion.
We examined several options; SCR is a process that requires significant investment and high consumption. According to the information provided by the designer, the cost is 23 yuan per ton of coke. Can’t afford it.
Supported; according to the parameters provided by a certain design institute, the tonnage of coke consumed is around 30
There are quite a number of new installations being put into use in the country at present. Comparison table of investment and operating costs per ton of coke for flue gas desulfurization and denitration processes. Item: Low-temperature SCR desulfurization/denitration, SICS desulfurization/denitration, Activated carbon/coke desulfurization/denitration, Catalytic desulfurization + low-temperature SCR denitration, High-temperature SCR denitration. Catalysts: Low-temperature catalyst, Low-temperature catalyst, Activated carbon/coke, Low-temperature catalyst, High-temperature catalyst. Absorbents: Desulfurizer: Na2CO3; Reducing agent: NH3; Oxidizing agent: Ozone. Adsorbents: Activated carbon/coke; Reducing agent: NH3; Adsorbent: New type of catalyst; Reducing agent: NH3; Reducing agent: NH3. By-products: Ammonium sulfate, **; High-concentration SO2 gases or sulfuric acid-based products. High-concentration SO2 gases or sulfuric acid-based products: --. Operating cost per ton of coke: 12 yuan, 7–8 yuan, 6–10 yuan, 5–7 yuan, 12 yuan. Investment cost per ton of coke: 30–40 yuan, 22 yuan, 30–36 yuan, 20–23 yuan, 31.3 yuan
The projects that have been completed and put into operation so far include the Baosteel Zhanjiang project (provided by MCC Coking & Refractory and for flue gas desulfurization and denitrification), as well as the Shandong Tiejiong Xinsha project (with two units, one developed by MCC Coking & Refractory and the other by Hefei Chenxi; both are only for flue gas denitrification). The main issue associated with low-temperature SCR technology for flue gas denitrification in coke ovens is the stability of the catalysts in operation
Please provide economic data such as investment and operating costs! Thank you! !
I heard that Dafeng Coking charges 12 yuan per ton for coke
I have only visited the Zhanjiang project; I haven’t obtained any detailed information. It is understood that the conversion rate for ton of coke is around 11–12 yuan per ton, though this figure may vary depending on the specific conditions of each coking plant.
The contract value for Baosteel’s project in Zhanjiang is 130 million yuan – it’s unaffordable. It was done by MCC Coking & Refractory and Anhui Tongxing.
