摘要:
A method for filling a tank (1) with pressurised gaseous hydrogen from at least one source storage (2) containing pressurised gaseous hydrogen at a first defined temperature and at a defined pressure higher than the pressure in the tank (1) to be filled, in which hydrogen is transferred from the source storage (2) to the tank (1) by pressure balancing via a filling circuit (3) having an upstream end linked to the source storage (2) and a downstream end linked to the tank (1), and in which the at least one source storage (2) exchanges heat with a member (6) for heating the gas stored in the source storage (2), during at least a part of the transfer of hydrogen from the source storage (2) to the tank (1), the gas contained in the source storage (2) being heated to a second defined temperature that is higher than the first temperature.

摘要:
Provided is a hydrogen station that supplies hydrogen to an external hydrogen tank, the hydrogen station including: a reciprocating compressor that is driven by a driver of which revolution is controllable; a cooling device that is capable of cooling hydrogen supplied from the reciprocating compressor to the hydrogen tank; a temperature sensor that detects an internal temperature of the hydrogen tank or a temperature of the hydrogen supplied to the hydrogen tank; and a control unit that controls the revolution of the driver based on the temperature detected by the temperature sensor.
摘要:
Es wird ein Verfahren zur Bereitstellung eines auf einen vorgegebenen Heizwert konditionierten Brenngases vorgeschlagen, bei dem aus einem Flüssigerdgas enthaltenden Flüssigerdgastank (1) zumindest ein Flüssigerdgasstrom (b) und ein verdampftes Erdgas enthaltender Gasstrom (d) abgezogen und unter erhöhtem Druck in eine Kondensationseinheit (4) eingespeist werden, in der das verdampfte Erdgas in dem Gasstrom (d) zumindest teilweise in den Flüssigerdgasstrom (b) rückkondensiert wird, und wobei aus der Kondensationseinheit (4) ein flüssiger Strom (f) abgezogen, druckerhöht und in einer Verdampfungseinheit (6) verdampft wird. Es ist vorgesehen, in die Kondensationseinheit (4) einen abgekühlten, Stickstoff enthaltenden Strom (I) in einer Menge einzuspeisen, die auf Grundlage des vorgegebenen Heizwerts eingestellt wird. Eine Anlage (100), die zur Durchführung eines erfindungsgemäßen Verfahrens eingerichtet ist, ist ebenfalls Gegenstand der Erfindung.
摘要:
Provided is a gas supply system in which the pressure of a compressed gas can be reduced in a stable state and the resulting gas can be supplied, as well as the system has an excellent economy and safety, wherein the pressure of a gas supplied from a source of a compressed gas (high-pressure gas container 11) is reduced by a pressure reducing means (pressure regulator 21, 31) and the resulting gas is supplied, wherein, on the upstream side, in the gas flow direction, of the pressure reducing means, a heat exchanger 22, 32 which heats the gas by heat exchange of a gas introduced to the pressure reducing means and warm water supplied from a warm water source (warm water circulation unit 15) is provided, as well as, in the pressure reducing means, a warm water flow channel 53 for heating the pressure reducing means by a part of the warm water is provided.
