| Significance and Use | |||||||||
|
3.1 Accurate knowledge of the weight and volume of butadiene is necessary for the orderly manufacture, storage, transfer, and sale of the material. These tables are suitable for use in these and similar aspects of butadiene commerce.
Enter the table in the column for
“Specific Gravity 60/60 °F'' headed 0.625, and note that against an
“Observed Temperature'' of 35 °F the factor is
|
1.027 |
||||||||
| Hence, 1 U.S. gal of butadiene of specific gravity 0.625 at 60/60 °F and measured at 35 °F occupies a volume at 60 °F of | 1.027 U.S. gal | ||||||||
| Then 45 500 U.S. gal measured at 35 °F occupy a volume at 60 °F of 45 500 × 1.027 or | 46 728 U.S. gal |
Enter the table with 0.625 specific
gravity and note that the weight of 1 U.S. gal is
5.201 lb
Then 40 U.S. gal of butadiene at 60 °F
weighs 40 × 5.201 or
208.0 lb
The weight to be set on the filling
machine is therefore
208 lb, 0 oz
A tank of 10 000 U.S. gal capacity is
observed to contain 1500 gal of liquid at 95 °F and consequently
40.1 psi gauge pressure and an observed specific gravity of
60/60 °F 0.627. The volume of butadiene vapors in the tank is
obviously 10 000 − 1500, or
8500 U.S. gal
Entering the table with either the
temperature of 95 °F, or the gauge pressure of 40.1 psi, the volume
of 60 °F butadiene liquid in each volume of vapor space is
0.01404
Then 8500 U.S. gal multiplied by 0.01404
gives the amount of butadiene in the vapor space expressed as U.S.
gallons of 60 °F butadiene liquid and is
119.3 gal
This 121.0 gal of 60 °F butadiene liquid
that is in the vapor space can be added to the liquid contents of
the tank expressed as U.S. gallons of 60 °F butadiene to obtain the
total contents of the tank.
From Table
2 the factor to correct the 1500 gal from 95 °F and a
specific gravity of 0.627 to 60 °F is 0.961; therefore, the liquid
content of the tank in U.S. gallons at 60 °F is 0.961 × 1500
1441.5 gal
The total contents of the tank in U.S.
gallons at 60 °F is 119.3 + 1441.5 or 40.1
1560.8 gal
The table can also be entered with the
temperature of 95 °F or gauge pressure of 40.1 psi reading the
vapor density in air of
0.0734 lb/gal
The weight of butadiene in the vapor
space of 8500 U.S. gal is therefore (8500 × 0.0734)
623.9 lb
From Table
2 the 1500 gal of liquid of 0.627 specific gravity and 95 °F
is multiplied by the factor of 0.961 to obtain the amount of
butadiene at 60 °F (1500 × 0.961)
1441.5 gal
From Table
3 the 1441.5 gal of butadiene at 60 °F with a specific
gravity of 0.627 is noted to weigh 5.218 lb/gal; therefore, the
weight of liquid butadiene is 1441.5 × 5.218
7521.7 lb
The total weight of butadiene in the tank
is 623.9 + 7521.7
8145.6 lb

1.1 The ASTM Butadiene Measurement Tables
are for use in the calculation of quantities of butadiene. The
accompanying Tables
1-4 cover the normal
operating ranges for the reduction of observed specific gravity and
volume to 15.6/15.6 °C (60/60 °F) and for the calculation of
weight-volume relationships of butadiene.
1.2 These tables are applicable to both butadiene and butadiene concentrates (minimum of 60 % butadiene).
Note 1: These tables replace the existing tables in the
National Institute of Standards and Technology Letter Circulars LC-736 and LC-757 and the Rubber Reserve Corp.,
Butadiene Laboratory Manual.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
