Description

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.

Description

CGA P-8.9 is intended for the guidance of those persons directly associated with the design, installation, operation, and maintenance of bulk cryogenic liquid storage systems. It does not claim to cover the subject completely but gives advice and should be used with sound engineering judgment. The intent of this guide is to ensure that a minimum, uniform level of safety is provided throughout the industrial gas industry for the protection of the public and industry employees.

This publication presents recommendations to reduce the possibility of large releases of stored cryogenic fluids from a storage system through installation of protective equipment and instrumentation, equipment inspection and testing, and storage system design criteria. It is the intent of this publication to emphasize prevention of releases. However this publication provides basic information about mitigation of releases even if they are remote.

A bulk liquid storage installation is defined, for the purpose of this publication, as the total fixed assembly of liquid storage tank(s) integrated with other equipment, such as pumps, filling equipment, pressure buildup vaporizers, controls and other related ancillary equipment that are connected to it.

This publication specifically covers storage installations on production sites where the storage tank is flat bottomed constructed and is connected to the production process plant and the individual tank capacity exceeds 125000 liters. For storage installations made with vacuum insulated tanks or cluster tanks or where the tanks have an individual capacity less than 125000 liters it is an individual company or storage system owner’s decision to use the present publication as a guide for the general requirements of the installation.
