Galvani Replaces Limited Closed System with PlantPAx

Solution

Understanding the importance of the project and recognising the challenges that the Galvani maintenance team faced, Rockwell Automation helped the company to execute a training program for the team involved in the project, using its Competence Center in São Paulo, SP.

Galvani decided to use the PlantPAx® solution from Rockwell Automation, due to its features and ease of use. PlantPAx has a library of objects with templates and open functions blocks, in addition to the Logix-View Utility (LVU) development tool that dramatically reduces the development time for the process control system.

For the implementation of the new system, Galvani adopted a virtual solution, using the existing IT infrastructure. To establish integration of the new control system with the existing Production Management system in the plant, Transaction Manager software was used, which simplifies integration between different systems.

Aiming to expand the time traceability of process data, Galvani used the historian software, working together with the reporting software, which is a powerful WEB reporting portal. This system is also used as a second analysis tool for production data. The data compression algorithms present in the historian software allow storage of a large volume of data in a reduced space, in addition to providing fast queries in the database, ensuring adequate performance to deliver reports.

To reduce investment in the project and the risks involved during plant shutdown, Galvani decided to migrate the controller CPU and maintain the 900 I/O points already installed. With this, the company focused its investment on the solution that would bring the necessary advances and better results for the project.

Results

The training of Galvani's corporate maintenance team was done in less than one week, due to PlantPAx system features, including a standard library of objects widely applied in different processes and various industries and the ease of use of the available tools for the system configuration.

The development, configuration and test of the entire system, with 900 I/O points was fully prepared, implemented and completed within the 20-day window allocated for the annual shutdown period, meeting one of the biggest challenges of the project.

With the support of the Field Engineering group at Rockwell Automation, Galvani's Maintenance team achieved the commissioning and start-up of the new system in just 12 hours, eliminating the risk of crystallization of the molten sulfur in the feed lines. This had been a major concern for the process team at Galvani.

The involvement of Rockwell Automation and the decision of Galvani to implement the system using its own engineering resources resulted in a 30% reduction in project implementation costs. The open system, total control and domain expertise acquired by Galvani staff also resulted in a significant reduction in expenditure for maintenance – a service that was previously delivered by third parties.

The problem of loss of communication was solved and there is no longer a dependence on a unique vendor for system maintenance.

Due to the flexibility and storage capacity of historical data from the plant, the new system is already used as a secondary analysis tool for production data, and in the future could replace the current production management system, with the implementation of new reports to be developed.

With the domain expertise that Galvani's maintenance team possesses, it is able to provide remote support for the system. Stefani Stival, corporate automation engineer says that he is using mobile devices like tablets and mobile phones to access the system screens and to provide the necessary support to operations staff at the plant. Moreover, the infrastructure deployed is already prepared for future migrations of other process areas of the plant.

The results mentioned above are specific to Galvani's use of Rockwell Automation products and services in conjunction with other products. Specific results may vary for other customers.
