Background Greater use of gas would make metal production more environmentally friendly while improving the competitiveness of Norwegian metal producers. By “gas” we refer here to natural gas, biogas, hydrogen and flue-gases from the metal production industry’s own and other industries’ production processes. Gas can replace coal and coke or provide a basis for the development of new processes t...

The purpose of this research was to determine the effectiveness of using corn burning heating appliances as an alternative to more traditional natural gas or electric heat. Two models of different sizes and outputs were purchased for the test. The appliances were operated through the winter and into the spring to evaluation their performance. The equipment was operated following the manufacture...

Pneumatic instrument systems powered by high-pressure natural gas are often used across the natural gas and petroleum industries for process control. Typical process control applications include pressure, temperature, liquid level, and flow rate regulation. The constant bleed of natural gas from these controllers is collectively one of the largest sources of methane emissions in the natural gas...

this study was conducted to evaluate the possibility of alfalfa replacement with fenugreek hay for ruminants, using in vitro gas production parameters and some of rumen fermentation characteristics. for this propose, five different total mixed rations were formulated to meet nutrient requirements of 35 kg growing lambs with gradually replacement of alfalfa in control diet (t1) with different le...

in this study greenhouse tomato production was investigated from energy consumption and greenhouse gas (ghg) emission point of views. moreover, artificial neural networks (anns) and adaptive neuro-fuzzy inference systems (anfis) were employed to model energy consumption for greenhouse tomato production. total energy input and output were calculated as 1316.14 and 281.1 gj/ha. among the all ener...
