We introduce new technologies, streamline production processes, and establish and upgrade our supply systems to ensure a safe, stable supply of city gas.
ˇˇThe gasification efficiency of liquid natural gas (LNG), a main component of city gas, is 100%, and its heat quantity is twice as much as the manufactured gas. Therefore, LNG doubles the performance of gas pipes and effectively reduces facility investment.
ˇˇWe are also upgrading and expanding the transmission pipelines and distribution networks to accommodate rising demand in the future and secure the safety of the gas supply.
