Do natural gas engines start better than diesel engines in cold weather? No engine is completely immune to cold-weather challenges. Some issues are common to most vehicles, including those using an internal combustion engine. One issue natural gas engines sometimes experience in freezing weather is...

The auto-ignition temperature of natural gas is 540 °C, and it is far higher than that of gasoline, which varying from 260 °C to 370 °C. This characteristic determines that the fire or explosion probability ofnatural gas vehiclesis lower than that of gasoline vehicles, when the collision...

potential problems where gas is transferred from one system to another (for example, the UK-Continent Interconnector), but the basic requirements are very similar. Excess water is removed to prevent the formation of hydrates and freezing in pipeline systems.Hydrogen sulphideis removed because it is...
The inclusion temperature measurements were performed using a Linkam THMSG600 heating-freezing stage following standard procedures in the State Key Laboratory of Petroleum Resources and Prospecting, China University of Petroleum, Beijing. The homogenization temperatures of both gas inclusions and the coeval...
using electricity and that creates hotter air that gets distributed around the house through ducts. Heat pumps are designed for colder weather but not when the outside temperature falls below -30 C, so an alternate heat source is required, either electric furnace/base...
