Cotton Seed Processing Company Saves Over $60,000 with Rosemount™ 3051SMV Transmitter
RESULTS
- Reduced hydrochloric acid consumption by 45 percent
- Achieved over $60,000 in annual plant operational savings
- Increased operational efficiency through process automation
MAINTAIN OUTPUT & SAVE COSTS
The processing plant was able to maintain their cotton seed output of 18,000 tons per year while reducing HCl usage by 45 percent, resulting in over $60,000 in annual savings.
The Rosemount 3051SMV Transmitter measures differential pressure, static pressure, temperature and dynamically calculates mass flow in real-time.
Customer
Cotton seed processing plant
Application
Anhydrous hydrochloric acid (HCl) gas flow measurement
Challenge
Cotton seed can be a particularly difficult feedstock to work with before a usable end product is produced. For one such facility in the United States, the cotton seed being processed had a particularly high amount of lint that had to be removed. To do this, hydrochloric acid (HCl) was used to crystallize the lint on the shells of the seed. The seeds were then sent to a tumbling drum that removes the hardened lint. The smoothened seeds were bagged in 50 lb (23 kg) sacks and placed on pallets for shipment.
The main concern of the plant manager was finding a way to reduce the operational costs of the lint removal process. Given that hydrochloric acid cost $0.85/lb (0.45 kg), plant managers were given the challenge of reducing their HCl use from 9 lb per ton (4.5 kg per metric ton) of seed to 5 lb per ton of seed (2.5 kg per metric ton).
Solution
Emerson worked with the plant engineers to assess the application and recommended the Rosemount™ 3051S MultiVariable™ Transmitter. The Rosemount 3051SMV Transmitter measures differential pressure, static pressure, temperature and dynamically calculates mass flow in real-time. This allowed the cotton seed facility to accurately measure HCl usage with a single device.
The Rosemount 3051S MultiVariable Transmitter was able to accurately compensate for pressure and temperature changes of the HCl gas to achieve reliable and repeatable mass flow measurement. As a result, HCl consumption was reduced by 4 lb/ton (2 kg per metric ton), helping the plant managers realize cost-savings goals. With an annual production rate of over 18,000 tons (16,300 metric tons), this amounted to $61,200 in savings. Because of the significant savings, the cotton seed producer has converted their other three facilities to include the use of the Rosemount 3051S MultiVariable Transmitter to automate and reduce their HCl use.
