Abstract
A method for lessening an initial pressure spike in a receiving tank caused by high pressure residual H-containing gas contained between a control valve and a block valve when dispensing the residual H-containing gas into the receiving tank. The block valve is briefly closed before the pressure in the transfer line decreases below a set pressure, thereby lessening the pressure spike in the receiving tank.
