Two-time Calibration at Both Ends for Sulfur Measurement by Using High Frequency Induction Infrared Absorption Method

نویسندگان

چکیده

Abstract High frequency induction heating infrared absorption method is a relative measurement method, and it requires calibrating the analyzer during process. Usually, one-time calibration on an made for high sulfur value by using standard substances. The proposed this paper calibrates carbon-sulfur analyzers with of two-time at both ends, which eliminates impact blank thus improves accuracy precision ultra-low measurement. extents lower limit in temperature alloy, to 0.00005%, namely, 0.5ppm.

Selection of the Best Efficient Method for Natural Gas Storage at High Capacities Using TOPSIS Method

Nowadays one of the most important energy sources is natural gas. By depletion of oil reservoirs in the world, natural gas will emerge as the future energy source for human life. One of the major concerns of gas suppliers is being able to supply this source of energy the entire year. This concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...
