Product Description A colorless gas with a choking or suffocating odor. Boiling point -10C. Heavier than air. Very toxic by inhalation and may irritate the eyes and mucous membranes. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Liquid sulphur dioxide (SO2) is a versatile chemical with many uses, both in liquid form or as a source of gaseous SO2. Liquid SO2 is used the pulp and paper industry, mining industry, and in the food industry as a preservative. It can function as a reducing agent, an oxidizing agent, a pH controller, purifying agent, preservative, a germicide and bleaching agent. SO2 can also be used as a refrigerant, heat transfer fluid and selective solvent.

It is a kind of petrochemical product, whose raw materials is green petroleum coke. It is widely used to produce graphite electrode, graphite blocks, brakes pads and other carbon products..It can also be used as carbon additive in some steel and aluminum plants, another, it is used in refractory, insulation, filler, etc. The main use of CPC is in the production of anodes for the Aluminum Smelting process. 70 - 80% of CPC is for the Aluminum Industry. The reason for use in the Aluminum Industry is for conductivity. Another use for CPC is TiO2 production which accounts for about 15% of the CPC consumption. The reason for use in TiO2 is for its oxidizing effect. Metallurgical Industry is the remaining major area where CPC is used. The reason for use in Metallurgical Industry is the high Fixed Carbon level (low ash level) and moderate sulfur levels. 300 thousand MT, which supplied more than 50% of the low sulphur grade used in Asia-Pacific, and we have so much advantage in low sulphur and medium sulphur grade CPC. Our quality is steady and excellent, which being the best service. So we have obtained great reputation from the majority of customers.

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.
