Energy Efficiency: Tracking Natural Gas With Flowmeters

By Wayne Shannon, Magnetrol International |

Thermal mass flowmeters provide advantages over other options for metering the consumption of natural gas by individual combustion units throughout the facility With today’s increased emphasis on strategic energy management, many throughout the chemical process industries (CPI) and elsewhere are attempting to obtain better information on the natural gas consumption in their facilities. While custody-transfer flowmeters are typically in place at the property line (to track total gas consumption throughout the facility), the flow to individual combustion sources, such as heaters, furnaces, boilers and so on, generally remains unknown. When armed with better information on actual natural gas utilization, users can optimize the combustion performance by operating combustion processes at peak efficiency.  Similarly, when users measure actual natural gas flow, they are able to determine which of their units is the most efficient. The operating efficiency of furnaces or dryers will vary. Knowing which process unit is the most efficient can result in significant cost savings. For instance, if more than one furnace, dryer or other type of gas-consuming unit is available, the user will be able to choose the combustion unit that provides the…
