Work package 6: Branch specific technical & economical feasibility

Tasks:

T6.1: Conventional drying systems per branch
To summarize available information of typical conventional drying systems in order to get a clear understanding of the technical and thermodynamic aspects of conventional drying systems for the company’s (especially SMEs) represented by branch sectors and user committees, revealing heat recovery opportunities. The task should be carried out for each different branch. Quantitative data on dryer size, energy sources with thermal efficiency, heat losses, operating hours, specific energy consumptions, energy costs etc. should be an important part of this description.
T6.2 Product-specific drying requirements
To list up a detailed property description of commonly dried products for each different branch and the need for their drying, in order to comprehend the different drying product-specific requirements. If possible moisture content variability of the fresh/dried product should be defined. The seasonally dependence and variability of the materials to be dried should also be described. Duly documented Reliable drying curves are to be determined from existing literature and research, companies or (in-house) experiments.
T6.3 Economic analysis of drying processes per branch
To summarize available economic information of typical conventional drying systems for each different branch. Quantitative data such as on investment, operational and maintenance costs, global/regional product throughput and value of dried product etc. are an important part of this description. The objective is to obtain a reliable view of the economic costs of currently existing, running or planned industrial drying processes.
T6.4 Branch-specific HPD integration and technical feasibility
For each industrial branch, to propose a HPD integration design for the conventional industrial drying system, and to analyse the thermodynamic feasibility of these HPD systems and to point out most promising HPD strategies. 
The starting point for each of these HPD proposal designs should be based on the current conventional industrial drying systems. The required input to propose these systems is ensured by previously defined tasks (T6.1 and T6.2) and their corresponding deliverables/milestones.
Besides, feedback from simulation models delivered in WP3 is necessary to point out heat pump integration possibilities and operation boundaries.
T6.5 Economic analysis of heat pump drying processes per branch
To evaluate the economic feasibility of the most promising HPD systems , also taking into account environmental aspects (input from WP5), and to compare the obtained results with costs of conventional drying systems, leading to a decisive-making criterion.
In case the findings indicate heat pump integration is not feasible in a certain sector, existing bottlenecks need to be clearly defined.
