vapor venting from above ground HC storage tanks 1

[spoonbill]

Does anyone have a spreadsheet program to make a reasonable estimate of tank venting losses resulting from solar heating?

Spoonbill:<br><br>If you are in the United States, have you had a look at the Section 4.3 of the U.S. EPA's publication AP-42? It deals with vapor losses from tankage.<br><br>Are you asking about fixed-roof storage tanks?&nbsp;&nbsp;If you are, AP-42 addresses both breathing losses (i.e., losses due to temperature changes) and working losses (i.e. losses from loading into the tank or loading out from the tank).<br><br>Or are you asking about floating roof tanks, or variable vapor space tanks, or tanks with<br>vapor recovery systems?&nbsp;&nbsp;AP-42 also addresses many of these tank types. <p> Milton Beychok<br><a href=mailto:mbeychok@home.com>mbeychok@home.com</a><br><a href=

The EPA also provide a TANKS program that calculates emmissions from tanks.<br><br>The program is free and available at<br><br><A HREF="

not a spread sheet but does come with complete documentation.
