Osisoft EMEA Users Conference 2017
news

OSIsoft EMEA Users Conference was held in London in October with a series of presentations, thematic panels, demonstrations of software tools and interactive workshops. The emphasis was on big data, IIoT & Industry 4.0, enterprise infrastructure and business intelligence.


Among others we attended the academic session where we discussed with the OSISoft experts the application in students’ education and for industrial cooperation.

We went from the meeting with an enthusiasm and new ideas for application of advanced predictive technology in the process industry for ​​monitoring and analysis of plant and process equipment performance.

New process control laboratory
news

Newly equipped process control laboratory was solemnly opened today at our Department.  

After six months of reconstruction the Faculty of Chemical Engineering and Technology in cooperation with Siemens AG and partner company ARP modernized the Laboratory for automation and measurement (LAM).

Within laboratory set-up modern control system with five typical process industry units is put into operation, all supported by the latest generation of SIMATIC PCS7 control system.

The new laboratory in Zagreb offers students, employees and partners the opportunity to train process measurement and control with state-of-the-art equipment.

Using cutting-edge digital systems, the training of future chemical engineers and life-learning education attendants, as well as commissioning engineers and operators, will take place here.

Industrial humidification system for Eriochem S.A.
news

During 2016 we designed the industrial humidification system now applied in pharmaceutical company Eriochem S.A., Argentina. The aim of the project was to design automated system for easy, safe and flexible humidification process. The humidification system includes supply water tank, vaporizer, delivery system and flow/temperature control system. Siemens PLC S7-1200 with HMI control panel is configured for process monitoring, control and data acquisition.

Developed industrial humidification process system enables accurate and repeatable production, safe and efficient process control as well as continuous data acquisition.

Process control performance improvement at INA Rijeka Refinery
news

In January 2017 we have finished one year-long project at the INA Rijeka Refinery which included:

• Detail analysis, diagnosis and optimization of control loops at 3 groups of plants (GP-1, GP-2 and GP-3);
• Installation and implementation of the modern monitoring and diagnostics system, identification and control loop tuning and simulation software.

350 control loops were analyzed and diagnosed. Based on the historical data control loop models were identified. Ultimately, the control loops were tuned using a high-level optimization tool and their performance was tested in the control room.

As the results 12 newly configured and 32 reconfigured control loops increase automation level of the plants. 30 control loops are switched from manual to auto mode.  In 54 control loops we reduced or eliminated oscillation thus increasing the overall plant stability. Sensor or valve problems were detected on 37 control loops. It is estimated that the number of alarms is reduced by 50 %. Finally, variability of the products properties and quality measures are reduced.

Optimisation project at INA Rijeka Refinery
news

We have just initiated large-scale project with the aim to provide monitoring, analysis and tuning of more than 350 control loops at the Rijeka Refinery process units.
Control loop audit will include diagnostics of the field instrumentation and control valves, define sources of variability and oscillation, and poor control loop performance.

The analysis will be foundation for control loops optimization which will result with decreased number of control loops in manual mode, reduced variability of controlled variables and more stable operation.
Additionally, the implementation of the advanced software package will provide a possibility to perform controller tuning education and on-site optimisation.
It is expected after project completion increased productivity, decreased equipment failures and prolonged service time, as well as increased process safety. All mentioned is a good base for advanced process control real application.
