PAGE 1 1 Introduction This standard contains minimum installation standards for bulk hydrogen supply systems. It is inte
20、nded to pro- vide recommendations for installing hydrogen supply systems. 2 Scope Two types of bulk hydrogen supply systems are covered in this document: liquid and gaseous. A bulk gas hydrogen supply system is one that contains greater than 5000 scf (141.6 m3) of hydrogen. A bulk liquid supply syst
21、em is one that contains greater than 500 gal (1890 L) of hydrogen. The requirements of this standard are limited to systems operating up to 15 000 psig (103.4 MPa).1, 2 For a liquid system, hydrogen is stored in liquid form and can be delivered in liquid or gaseous form to the end users requirement.
22、 Pumps and/or compressors may be used to increase the hydrogen pressure before it is delivered to the end user. Gas receivers may be used to store gaseous hydrogen before it is delivered to the end user. The system is still considered a bulk liquid system because the hydrogen is delivered from the h
23、y- drogen supplier to the storage system in liquid form. For a gas system, hydrogen is delivered to the supply system, stored, and is delivered to the end users re- quirement in gaseous form. See Figures A-1 through A-6 in Appendix A for typical gas and liquid system flow diagrams. This standard app
24、lies to hydrogen supply systems containing any of the following equipment. Not all hydrogen systems include all the equipment listed. More details about hydrogen applications can be found in CGA G-5, Hydrogen 2. Hydrogen supply systems include: cryogenic hydrogen storage tank, either aboveground or
