Good Calibration Gas - For the Natural Gas and LNG Industry

Oil refineries line a river in Yokkaichi, Japan. The city has been a center for the chemical industry since the 1930's..jpegA calibration gas is a reference gas mixture used as a comparative standard in the calibration of analytical instruments, such as gas analysers, gas chromatographs or other gas measurement devices. If it is important that the instrument is capable of making good measurements, then the reference standard used to calibrate it is equally important. 

Throughout this paper we are going to look at what makes a good calibration gas, the benefits it can provide and how it all relates to the measurement of Natural Gas or LNG. ...read more.

Three Steps to Accurate Gas Metering Heaven

CAC_Gas_Measurements.pngCombined cycle gas turbine (CCGT) power stations, combined heat and power (CHP) plants, gas storage sites and intensive energy using industries burn or handle very large quantities of gas per annum. This gas usually represents one of the greatest input costs (and hence risks) to their business, a cost which is mainly determined by the accuracy of their gas metering and the price paid for the gas. Companies often go to great lengths to make sure the commercial arrangements for gas purchase are as favourable as possible, but overlook the obvious question: Actually, how accurate is our gas metering?             Read more...
