"Improved energy and resource efficiency by better coordination of production in the process industries" (CoPro) addresses the call SPIRE 02-2016 and will make significant contributions towards
efficiently utilising existing plants by integrated plant-wide scheduling and control;
better coordination of connected units in a site and within a chemical park;
buffering the effects of fluctuating renewable energy production and distribution by integrating demand-side response with plant-wide scheduling and control.
CoPro will provide tools for the plant-wide optimisation of continuous and discrete decisions, will develop technology for balancing production and consumption in industrial parks for industrial symbiosis and will address power plant scheduling and demand-side response.
We will develop online data analytics and novel forms of information presentation that lead to a symbiosis of operators and computer-based control algorithms. The solutions will be integrated into the IT infrastructure of the plants via a neutral integration platform that connects to different IT systems. CoPro will pay special attention to methods for the efficient development of plant models as the basis for advanced control, scheduling, and coordination.

The goal of the CoPro project is to develop and to demonstrate methods and tools for process monitoring and optimal dynamic planning, scheduling and control of plants, industrial sites and clusters under dynamic market conditions, to provide decision support to operators and managers and to progress to automated closed-loop solutions to achieve an optimally energy and resource efficient production.
The objectives are motivated by challenging and characteristic use cases from different sectors of the process industries:
The technologies that are developed are nonetheless of a generic nature and can be applied to all sectors of the process industries and also to production sites in other sectors. CoPro builds upon results of the MORE www.more-nmp.eu and DYMASOS www.dymasos.eu projects and makes a further step forward to apply and extend them to plant-wide coordination and control, and towards market-based coordination mechanisms for Industrial Parks.
INEOS in Köln (Cologne, Germany) operates an integrated petrochemical complex to produce a large number of important base chemicals. The site consists of more than twenty plants, more than ten utilities networks and a large number of storage tanks.
There is complex interaction between the different INEOS plants, with site logistics and with other plants owned by other companies in the chemical park. Today, daily production (products and energy) is planned for the year ahead using a central planning tool.
The focus of the planned work related to the INEOS site is to achieve an optimal short-term planning and scheduling and operation of large units (crackers) and of the complete site.
INEOS operates two steam crackers offering continuous degrees of freedom in plant operations and discrete degrees of freedom in feedstock planning and furnace decoking scheduling.
Optimal site operation is a combined continuous optimisation and scheduling problem as not all plants are operational all the time. The real-time solutions need to interact with long term planning to provide automatically coordinated site operation for planned and unplanned plant shut-downs and maintenance.
Demand-side management can contribute significantly to the economics of the site as well as to the reduction of the CO2 footprint if more electricity from renewables can be used on average.

At the Dormagen site, Covestro Deutschland AG produces base chemicals as intermediates for polymers. Of these base chemicals production units coupled units will be picked as use cases to find an overall optimum across more than one unit. It will include the planning of partial shutdowns of units due to maintenance or demand fluctuations.
In chemical parks, as in the Dormagen/Köln ChemPark where Covestro and INEOS in Köln are located, companies exchange streams of energy or materials via networks with limited storage capacity. Often such couplings are multiple such that the plants are connected by several flows in both directions. This leads to a coupled allocation problem, because when one company changes its production levels or its product mix this affects the others and may lead to cascading effects. Current practice is to negotiate corridors of flows with associated prices which are both fixed over long horizons. As production demands change quickly and the response to the availability of “green” electric power (demand-side management) asks for flexible production, the need for a more dynamic and semi-automated management of the exchange streams arises. This creates a potential to operate the plants optimally with respect to energy and resource consumption. The benefits of the exchange and the cost of the flexibility must be computed and distributed fairly among the participating companies. Due to confidentiality reasons and anti-trust legislation, the management of the exchange flows of material must be performed with a minimum amount of information about the demands, restrictions, cost structures etc. of the plants and companies involved. Market-based algorithms that have been developed by TUDO in the DYMASOS project can compute the joint optimum on the basis of confidential individual optimisations of the participating companies by adapting the exchange prices. In CoPro, we develop this idea further to include partial shutdowns of units due to maintenance or demand fluctuations as well as the optimal procurement of resources from external providers.
The Lenzing Group operates in Upper Austria the world´s largest fully integrated pulp and Viscose® fiber production site. In the Viscose® fiber production the recovery of the spinbath is a key process step with the highest energy demand. In this recovery process the diluted spinbath liquid gets reconcentrated and the co-product sodium sulphate gets extracted. The recovery is performed by evaporation, crystallisation and calcination process units.
The evaporation unit consists of many different evaporators. To optimally operate this unit the plant supervisor has to schedule the load, the cleaning cycle and the allocation of every single evaporator while taking a number of boundary conditions into account.
River water is used for the cooling of the most evaporators. The river water is limited and has to be distributed optimal to reduce the overall energy consumption. The usage of the river water also creates algae deposits on the surface condensers of the evaporators. To increase the efficiency of the condensers an improved scheduling for the removal of the algae deposits is necessary.
A large number of heat exchangers is used to shift the energy between the different operation units. The efficiency of these exchangers decreases due to fouling. An optimised management of the cleaning cycles will result in a higher overall energy efficiency.
The goal of the application of the technologies developed in CoPro to the Lenzing use case is to achieve a plant-wide coordinated operation of the recovery section, in particular by optimal planning and scheduling of cleaning steps and an optimal choice of the equipment and resources that are used in the operation.
P&G operates one of its largest detergent making plants in Europe where it co-locates with other companies for collaborative production and operates several platforms of products. The site makes hundreds of different complex products, including a range of detergents. Some ingredients are shared but many different formulations are produced combining both continuous and batch processing steps. All products require synchronised packing of bottles, tubs and bags as well as palletisation units. The production needs to be real time demand-driven by retail customers.
The integration is so far mostly manual on the basis of individual process controls and would tremendously from integration.
Specifically, the key challenges that will be addressed in CoPro are:
FRINSA DEL NOROESTE (Ribeira, Spain) is the third largest canning company in Spain. The factory processes more than 500 t/day of 25 different raw materials and produces an average of 3.5 million units per day of more than 3,500 different finished products.
The utility network that supplies thermal energy for cookers, sterilisers and Cleaning in Place includes a cogeneration plant. So far, daily site production is planned for the year ahead using a central plan in SAP and Excel, then planned monthly, and rescheduled manually on a weekly and daily basis in response to product demand (different products and formats), raw material availability (at competitive prices), unpredicted downtimes, CIP and failures.
Typically, more than 40 Process Orders of different products coexist along the plant, even in the same process line. Materials have to pass through batch and continuous processes along their routes, FRINSA's main challenge to be tackled is to optimally plan and schedule equipment operations and processes, continuous (filling and packing) and batch (cooking and sterilisation) in order to minimise waiting times, downtimes, avoiding coupling and queues), reduce lead-time and plant energy consumption.
Different products can coexist in different units and changeovers may happen while the previous Process Order is still running. In particular, the coordination of the operation of cookers and sterilisers is required what may include readjustments of temperature/pressure set-points for the different units. The underlying optimal control problems need to be solved on a real-time basis and must take into account quality and safety specifications (lethality) that must be estimated from the available sensors.
