The intricacies of odorant shipping demand meticulous calculations, especially when dealing with specific tank sizes. In this blog post, we explore the detailed process of calculating the maximum odorant volume for a 28-gallon tank, weighing 85 pounds. Using the density of a common odorant blend as an example, our focus is on customizing calculations for different tank sizes within the odorant industry to ensure compliance with regulatory standards.
Per 49 CFR §173.6, Materials of trade exceptions, hazardous containers with odorant may be transported without shipping papers, if in direct support of a principal business and if carried in containers with a volume of less than 8 gallons or weight of 66 pounds and of packaging group 11, Ill or ORM-D and if the total aggregate gross weight including packaging of all material of trade items on the vehicle does not exceed 440 pounds.
Understanding Tank Specifications: For our example, we concentrate on an 85-pound, 28-gallon tank. The weight of the tank is a critical component, significantly contributing to the overall packaging weight. Additionally, the density of the odorant, determined by specific gravity and water density, remains central to precise calculations.
Variables for the 28-Gallon Tank Calculation:
Weight of packaging (tank): Set at 85 lb.
Specific gravity of odorant: 0.812 from SDS
Density of water: Established at 8.33 lb/gal.
Odorant density: 0.812 x 8.33 = 6.76 lb/gal.
Volume Calculation for the 28-Gallon Tank: The odorant volume per tank is straightforward, as a 28 gallon tank filled to 80% capacity. Therefore, the odorant volume per tank is 22.4 gallons.
Determining Maximum Tanks and Total Volume: Using the weight of the tank and the calculated mass of odorant per tank, we determine the aggregate weight of each tank (85 lb tank + 151.5 lb mass of odorant). Dividing the maximum weight limit (440 lb) by the weight per tank yields the maximum number of tanks permissible within the shipping limit – approximately 1.8 tanks. The maximum number of 80% full tanks is 1.
This detailed calculation highlights the importance of precision in odorant shipping. By customizing calculations based on specific tank sizes and odorant blends, companies can optimize their shipping processes while ensuring strict adherence to regulatory requirements. This meticulous approach not only enhances efficiency but also contributes to the overall safety and compliance of odorant transportation in the industry.
