Emerson's PlantWeb architecture has enabled ZT Kruszwica to increase production by 10%.The process is fully automated using over 100 of Emerson's Baumann and Fisher control valves and over 950 ON/OFF valves fitted with Emerson's El-O-Matic actuatorsEmerson's instrumentation and DeltaV system are helping to save energy at ZT Kruszwica. One example is the introduction of new temperature measurement points on the heat exchanger. Four Rosemount temperature transmitters are now used where previously only one was in place. The increased data made available from these additional instruments showed that the heat exchanger was only 50% efficient. Improvements were made to the program running this section of the process and efficiency was increased to 90% by using the DeltaV system. This has seen energy reduced by 1300GJ a month which amounts to EURO 77,000 a year.
The new plant, incorporating Emerson's digital architecture and DeltaV, has helped save valuable resources. There has been a significant reduction in the amount of raw materials and utilities used; hexane consumption and the use of bleaching earth have been reduced by 25%. This is as a result of constantly improving the programmes run by the DeltaV system. A new closed loop system that returns water back into the process has decreased water use by 75%.
This process is fully automated by the PlantWeb architecture, using over 100 of Emerson's Baumann™ and Fisher® control valves and over 950 ON/OFF valves fitted with Emerson's El-O-Matic® actuators, all controlled by the DeltaV system. Utilities are measured by Rosemount Vortex and Magnetic flowmeters.
