#CMT# #/CMT# In a method for filling pressurized gas into a reservoir (11, 12) by compressing gas from a first source (1) to fill the reservoir directly or via buffer container(s) (2, 3) using energy from a working fluid (4), heat exchange is carried out between the compressed gas and the working fluid. #CMT# : #/CMT# An independent claim is included for apparatus for the process, comprising source(s) (1) of gas under a first pressure, a compressor (6) actuated by a working fluid (4) to compress the gas from the source, a source (40) of the working fluid, a gas compression controller (6) and (as novel feature) heat exchanger(s) (9) for exchanging heat between the compressed gas and the working fluid. #CMT#USE : #/CMT# Especially for filling hydrogen into the reservoir of a vehicle (claimed), e.g. a vehicle operated by a fuel cell or an internal combustion engine adjusted to run on hydrogen. #CMT#ADVANTAGE : #/CMT# Excessive heating of the gas due to rapid compression during filling (which is a potential cause of damage to the reservoir material, especially in the case of rapid filling) is controlled by the heat exchange between the compressed gas and the working fluid. The energies for compression of the gas and for cooling is carried by the same fluid. No electrically operated refrigeration devices are required, so that electricity consumption is minimized. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a schematic view of one form of the filling apparatus. 1 : First gas source 2, 3 : Buffer container 4 : Working fluid, consisting of nitrogen 5 : Cold/heat carrier or accumulator 6 : Gas compressor 7 : Line by-passing first heat exchanger 8 : Line with first heat exchanger 9, 16 : Heat exchanger 11, 12 : Gas reservoir 13, 14 : Connecting lines 18, 1, 51, 52, 53, 56, 61, 76, 86, 131, 132, 135, 145, 141, 142, 203, 204 : Valves 21, 22, 23, 134, 144, 202 : Safety outlets to the atmosphere 26, 31, 32, 33, 96, 133, 143 : Pressure sensors 36 : Compressor outlet line 40 : Working fluid source, consisting of liquid nitrogen reservoir 46 : Particle filter 66 : Temperature sensor 101 : Compressor feed line 116 : Heat exchanger supply line 136, 146 : Coupling systems 201 : Branch line #CMT#CHEMICAL ENGINEERING : #/CMT# Preferred Process: Heat exchange is carried out using working fluid (4) before use to compress the gas and/or working fluid not used to compress the gas. Preferred Apparatus: Heat exchange in the heat exchanger (9) between the compressed gas and working fluid is carried out indirectly using a heat/cold carrier or accunulator (5), such as aqueous glycol or aluminum. |
