Abstract
982,791. Supplying inert gas to storage tanks &c. B.P. TANKER CO. Ltd., A. T. MACKENZIE, and E. TELFER. Oct. 10, 1962 [Oct. 26, 1961], No. 38353/61. Heading A5A. A system for supplying inert gas to storage tanks, e.g. in ships, comprises cooling means for inert gas (e.g. boiler flue gas, diesel exhaust gas or gas from a propane burner) and a fan for blowing the cooled gas into the tank, the maximum pressure which the fan can generate being equal to a predetermined value which is the pressure (usually slightly above atmospheric pressure) at which the tank is to be maintained. In the embodiment shown diagrammatically in Fig. 1, inert gas from a boiler uptake is drawn through a scrubber 1 and a filter 2 by the fan 3 driven by motor or turbine 4. The fan blows the inert gas into a main header 5 having side branches 6 carrying the gas to cargo tanks 7, each of which is fitted with a purging pipe 8 extending to the bottom of the tank and fitted with a valve (hinged cover with seal) 9, which enables gas to be blown through an empty tank to displace the air therein. Conversely, the fan may draw fresh air from the atmosphere through an inlet between valve 19 and scrubber 1 to replace inert gas with fresh air when desired. The main header 5 is vented to the air by vents 10, each of which is provided with a gate-valve 11 and a pressure and vacuum relief valve 12 connected in parallel, the former enabling tanks 7 to be vented during loading and the latter, being set to operate at + 2 and ¢ p.s.i.g., serving to release any pressure build-up due to volatilization of cargo. Inert gas is supplied to the main header 5 via a gate-valve 13 and non-return valve 14, and an oil-seal pressure and vacuum breaker 15 is provided as an additional safeguard. A pressure stat 16 is provided to start and stop the fan motor when the pressure reaches or falls to a predetermined figure (0.4 p.s.i.g. and 0.18 p.s.i.g. respectively), and an additional pressure stat 18 is set to give a warning if the pressure falls below 0.18 p.s.i.g. Specification 649,735 is referred to.
