Abstract: A method is described for igniting discharges of inflammable fluids, such as gases which are discharged in a flare, where an ignition pellet is set in motion towards the fluid discharge along a conducting body and made to detonate in or near the fluid discharge, so that the fluid is ignited. The invention is characterised in that the device, during its travel towards the fluid discharge, goes through detonation generating events in which an electronic system registers several subsequent sequences, such as: 1) a sequence in which a control circuit (a system) is activated (switched on), 2) a sequence in which the device is activated as it passes, and registers a predetermined series of identical or different pulse influences, and 3) a sequence in which the device thereafter is made to detonate by a pulse influence which indicates that it has passed the conducting body towards the fluid discharge. A system for carrying out the method is also described.

Abstract: A method for the handling of covering gas or inert gas in connection with a tank that conveys crude oil, during successive discharging and loading operations of the tank, is disclosed. The method is characterized by the fact that covering gas/inert gas is re-circulated in an approximate closed circulation by the following steps: that during discharging of the tank, covering gas is produced in a recognized manner known per se from the cargo to fill the gradually increasing void space in the tank, and that when the tank is filled again with crude oil, the gas from the tank is extracted again, and it is compressed and absorbed into the stabilized crude oil. An apparatus is mentioned for accomplishing the method.
