<p>The cleaning method has the pipeline system filled with a cleaning solution at a pressure in the region of 1 bar, which is retained over an interval of between 1 and 5 hours, for releasing pipeline deposits, before discharge of the cleaning solution in opposition to the normal flow direction. The pipeline system is then at least partially filled with a gas and sealed before filling with liquid at the supply pressure of between 4 and 8 bar for compression of the gas, which is expanded upon discharge of liquid.</p> |
