          District heating plants
        
        
          Use gas to heat water,

          heating networks.
        
        
          PRODUCTION, DISTRIBUTION AND USE OF NATURAL GAS
        
        
          THE DIAGRAM SHOWS THE ROUTE GAS TAKES FROM BEING BROUGHT TO THE SURFACE TO FINDING ITS WAY TO THE END USER (E.G., A DETACHED
        
        
          HOUSE OR A DISTRICT HEATING PLANT). NATURAL GAS, AS EXTRACTED FROM A BOREHOLE, DIFFERS SIGNIFICANTLY FROM THE GAS USED IN OVENS
        
        
          OR BOILERS. ITS PROPERTIES CHANGE, MAINLY DURING ITS PROCESSING IN A GAS PROCESSING PLANT, WHERE IT IS DEHYDRATED, PURIFIED AND
        
        
          ODORIZED. THEN IT IS PRESSURISED AND TRANSPORTED BY PIPELINE TO STORAGE, INDUSTRIAL PLANTS, OR HOUSEHOLDS. THE TRANSMISSION OF
        
        
          GAS IS MANAGED BY SPECIALISED COMPANIES AND INSTITUTIONS KNOWN AS TRANSMISSION AND DISTRIBUTION NETWORK OPERATORS.
