Coking industry laboratory
Thread Content
Are there laboratory staff in the coking industry? Let’s exchange ideas; I really need everyone’s help. Please mention Haichuan Chemical Forum when adding me. This post was last edited by Canghai Yili Sha on 2009-3-1 11:42.]
You can post those questions! I may not be involved in coking testing itself, but I work to support such testing; I can help you, and you don’t need to worry too much about other business matters... Hehe
Thank you so much! I have just entered this industry and am planning to set up a laboratory. The first thing I need to determine is which tests are required in the coking industry. I hope everyone will give their support. :handshake
I have worked in a laboratory, mainly dealing with the analysis of coking and coal tar. The main analysis parameters for coke include moisture, ash content, volatile matter, and fixed carbon; these values can be calculated accordingly. There is also water quality analysis
Support what was said above. In the analysis of coke and coal, in addition to what was mentioned above, sulfur testing is also required. Benzene and naphthalene in gas and coal tar are both subject to analysis. The instruments used generally include: muffle furnaces, electronic balances, sulfur determinators, gas chromatography, and so on...
I work in the laboratory of a coking plant. Our analysis projects mainly include: 1. Coal quality analysis: Since we have a coal washing plant, coal quality analysis involves the selectivity and caking property of raw coal ； The quality analysis of the coal fed into the furnace is divided into two parts. 2. Coke quality analysis: includes two aspects, namely coke ash grade and strength. 3. Water quality analysis: includes both wastewater and circulating water. 4. Analysis of coking by-products: crude benzene, coal tar, etc ； Of course, there is also some gas analysis.
If there are special requirements, tests for iron, aluminum, silicon, phosphorus, etc. are also needed
Thank you very much for your reply. How is the selectivity of raw coal determined? What other gas analysis tests are performed? What method was used?
Are there any analysis procedures for related analysis projects? As well as the reference standard numbers.
Reply to the original poster: The criteria for coal selectivity are specified in the national standards GB/T 478-2008 \"Methods for floating and sinking tests of coal\" and GB/T 16417-1996 \"Methods for evaluating coal selectivity\". In the more primitive gas analysis methods, 1901 or 1904 Austen analyzers were used to measure parameters such as carbon dioxide, carbon monoxide, unsaturated hydrocarbons, methane, and oxygen content ； Advanced chromatography is used. For example, we use chromatography to analyze the contents of benzene and naphthalene in gas. There are numerous standards for coal quality analysis, and I have them almost all. If the original poster or anyone above needs them, they can contact me via in-site messaging.
I worked in a laboratory for a few years, mainly handling technical management tasks. Our factory is a coking plant with an annual production capacity of millions of tons; the chemical products produced include tar, refined benzene, ammonium sulfate, etc. If you need any assistance, please feel free to contact me.
