Scope UV fluorescence sulfur analyzer is based on UV fluorescence measurement principle and the development of computer technology combined with a new generation of precision instruments, is currently the most advanced of the total sulfur content tester, in line with ASTM D5453, SH / T 0689 and other standards, the instrument is National total sulfur content of refined oil arbitration standards. Now widely used in the determination of total sulfur content of crude oil, hydrocarbons and fuel, petroleum, plastics, petrochemicals, food and so on. Measurement principle instrument uses ultraviolet fluorescence method, when the sample is introduced into the pyrolysis furnace, cracking occurred sample oxidation of sulfide which quantitatively converted to sulfur dioxide, carried by a carrier gas, off which the water through a membrane dryer, into the reaction chamber, sulfur dioxide absorbing ultraviolet light energy into an excited state of sulfur dioxide (SO2 *), the fluorescence emission of sulfur dioxide when SO2 * to return to a stable state, the energy released by a photomultiplier tube to receive, and then the micro-current amplifier, computer data processing, the amount of reaction with sulfur dioxide emission intensity is proportional to the amount of sulfur dioxide and total sulfur content in the sample is proportional, so the content of the sample can be determined by measuring total sulfur emission intensity. Features 1, computer-controlled operation, enabling interactive, data, peak shape can be automatically stored print. 2, the operating software can be connected with LIMIS system, automatic data transmission. 3, the instrument uses the new quartz pyrolysis tube, the injection volume can be increased to reduce measurement errors, increase the sensitivity of the instrument, higher repeatability. 4, cooling fans, automatic switch, eliminating the need to wait for the shutdown to finish samples trouble, saving time and effort. 5, darkroom system uses the latest technology, the key components imported detecting element to improve the detection accuracy and sensitivity of the instrument. 6, equipment imported membrane dryer to absorb , eliminating the need to frequently replace magnesium perchlorate of trouble, while reducing the leakage problem. 7, using computer control of temperature, improve the instrument precision temperature control, and difficult to over-temperature. 8, using air instead of water cooling, saving water resources. 9, can be adjusted to take existing calibration curve calibrated using a standard sample after sample analysis.

#semi coke#gas coke#lam coke#met coke#foundry coke#nut coke Semi coke can be 100% used in the production of ferrosilicon and ferronickel, reducing production power consumption and increasing single furnace output. If you are interested in our products, please contact us to provide the latest market consultation and free samples for your reference. In case you have any interests, please do not hesitate to contact us.
Semi coke is made from high grade Jurassic coal as a new type of carbon material. Semi coke produced in China, and main production city in Shaanxi China. Semi coke can instead of metallurgical coke to be used in producing ferroalloys products. Semi-coke is light black, characterized by high fixed carbon, high specific resistance, high chemical activity, low ash content, low sulfur and Low phosphorus. It is wildly applied to chemical industry, metallurgic industry, and gas- making industry to produce Ferroalloys, ferrosilicon, Ferronickel ,Ferrochrome, FeMn & SiMn, as well as Calcium carbide and, fertilizer, etc. F.C.: 84% min Ash: 8% max Volatile matter: 8% max Sulfur: 0.35% max Moisture: 18% max Semi coke is made from high grade Jurassic coal and as a new type of carbon material. It can be instead of some metallurgical coke when produce ferroalloys products. Using semi coke during steel making, blended the semi coke with met coke, which reduced their cost 20% to 30% than using met coke only. Advantage of semi coke than Met Coke in production of Ferro-alloy smelting as deoxidizer (1). Semi Coke could improve the quality of the ferro alloy significantly (especially low aluminum alloy Al2O3â?¤0.1%). (2). Semi Coke could reduce unit electricity consumption significantly (nearly save more than 1000 KWHR, that means 8-10%) (3). Semi coke could lower the cost of raw material. Although the price of semi coke and coke is similar, but its far cheaper than charcoal and pet-coke (4). Its very simple to replace coke, pet-coke and charcoal with semi coke. Its no need to upgrade your equipment and the operation is easy and process is simple.

Sulfur dioxide (also sulphur dioxide) is the chemical compound with the formula SO2. It is a poisonous gas with a pungent, irritating smell, that is released by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide unless the sulfur compounds are removed before burning the fuel. Further oxidation of SO2, usually in the presence of a catalyst such as NO2, forms H2SO4, and thus acid rain.[2] Sulfur dioxide emissions are also a precursor to particulates in the atmosphere. Both of these impacts are cause for concern over the environmental impact of these fuels.
