Process control
INEA has developed its own process control technology:
- Processes in process and chemical industries
- Ecology and energy management processes
- Development and production of process control tools
We provide the following services:
- Feasibility studies and conceptual projects
- Developmental tasks and projects
- Design and installation project documentation
- Implementation and delivery of process control and management system
- Installation and start-up (commissioning)
- User and maintenance staff training
- System maintenance
- Engineering projects (contractual or consulting) of complex systems
Integrated functions of continuous and batch process control systems include the following options:
- Process parameter control
- Creation and execution of recipes
- Alarming the deviations of values of process variables
- Automation of process start-ups and shut-downs
- Advanced coordination control between processes
Processes where we implemented control:
- Flue gas cleaning
- Decanter washing
- Milling of raw material
- Cooling of calcinate
- Hot melt adhesives
- Vulcanizing boilers
- Solution filtration
- Gel spinning and pre-drying
- Cooling of titanium dioxide
- Auto-tuning temperature control and hydraulic control
- Neutralization
- Brick drying
- Production of PVA adhesive
- Preparation and adding of reactants
- Milling, pre-mixing, digestion and preparation of rutile seeds
- Production and separation of crude oil
- Batch chemical processing
- Washing and drying, preparation of NaAl and Al2SO4 and the micronization process in the TiO2 production
- Peptization in the TiO2 process
- Pigmentation in the TiO2 process for controlling batch chemical processing in the TiO2 process
- Crystallization in the TiO2 process
- Glass furnaces
- Pulp cooking
- Aeration in anaerobic waste water purification
Our solutions of process control systems therefore target the following objectives:
- Increase in product quality and reproducibility
- Decrease in production fluctuations
- Shortening of production cycle and consequently increase in product quantity
- Bottleneck detection in production
- Implementation of solutions for quick data archiving for the purposes of process complex analyses
- Energy saving
- Facilitating operator’s work and increase in control from control centres
Our program applications are based on automated quick capture and efficient storing of process data. The modular system structure enables the user to choose a configuration in accordance with its own needs and upgrade it with new modules at anytime.
For control of batch processes we developed PLCbatch, which enables S88.01 compliant recipe control on PLC platform with a high reliability performance.
Control systems are based on our own solutions and high-quality equipment of recognized producers:
- Mitsubishi Electric System Q,
- Siemens PCS7,
When fast archiving of large amount of data or a complex analysis of processes and data is needed, we use the software of:
References
- TiO2 production (crystallization, reduction, batch chemical processing),
- Peptization, hydrolysis, washing, drying, micronization),
- Rubber industry (vulcanization of rubber products)
- Adhesive industry (hot melt adhesives, PVA adhesives),
- Brickworks industry (brick drying and baking),
- Leather industry (tanning of hides and skins, leather dying),
- Wood industry (log cooking for veneer production),
- Glass industry (glass melting),
- Paper industry (cellulose cooking).
The current number of all implemented applications is more than 50.
