CGA P-8.9 PDF

This publication specifically covers storage installations on production sites where the storage tank is flat-bottom constructed, is connected to the production process plant, and the individual tank capacity is greater than 125 000 liters.

See Appendices A and B, for bulk liquid storage installations on production sites where the storage tank(s):

• is vacuum-insulated constructed with an individual capacity greater than 125 000 liters;
• are manifolded vacuum-insulated tanks with a combined capacity greater than 125 000 liters;
• are cluster tanks where the tanks have a combined capacity greater than 125 000 liters; or
• are combinations of vacuum-insulated tanks and cluster tanks that are manifolded together and have a combined capacity greater than 125 000 liters.

The information contained in this publication applies only to new installations designed after the publication of this document and not to existing installations. However, the information contained in this publication may benefit existing installations or those in the project phase.

Specific requirements for loading systems can be found in CGA P-31, Liquid Oxygen, Nitrogen, and Argon Cryogenic Tanker Loading Systems.

For flat-bottom storage tanks not connected to a production process plant, the requirements of this publication shall be met. For vacuum-insulated tanks or other storage configurations, see Appendices A and B.
