WebMar 1, 2024 · HHV stands for higher heating value while LHV stands for lower heating value. The key difference between HHV and LHV is that HHV can be determined by bringing all the products of combustion back to the original pre-combustion temperature while allowing any produced vapour to condense. WebTypically, with a low-ethane-content gas, the heating value specification of 1100 Btu/scf can be met. However, with a higher ethane content feed, the heating value of the residue gas may exceed specification. Particularly, in western United States and Europe, a very lean gas with low British thermal unit content is required.

WebApr 14, 2024 · High-TRL direct electric heating and hydrogen combustion require low capital investments and offer process flexibility and modularity relative to traditional technologies. The difference between the two heating values depends on the chemical composition of the fuel. In the case of pure carbon or carbon monoxide, the two heating values are almost identical, the difference being the sensible heat content of carbon dioxide between 150 °C and 25 °C (sensible heat exchange causes a change of temperature, while latent heat is added or subtracted for phase transitions at constant temperature. Examples: heat of vaporization or heat of fusion).
