The Austrian symposium on smart production: reduction of CO2 emissions in producing enterprises

On the 20th of October 2011 a symposium on Smart Production – Reduction of CO2 emissions in producing enterprises was successfully held in Graz, Austria, organised by the Austrian Energy Agency and AEE INTEC. The day was divided into four main blocks:

  • energy consulting
  • efficient technologies for heat and cold supply
  • increase of efficiency in the food industry
  • increase of efficiency in the metal surface treatment industry.

The event was attended by more than 50 people from the industry (food and metal treatment), energy consultants, stakeholders and funding bodies.

During the presentations the audience was presented with specific subject concepts from each industry, as well as real case studies from the food and the metal surface treatment industries. In addition the audience was presented with options of possible funding within the energy audits targeting the increase of energy efficiency.

The event was an excellent opportunity to present the ongoing work and first results of the EINSTEIN project. Starting with the idea behind EINSTEIN II, the methodology and the software were presented. This demonstration created a huge amount of interest amongst energy consultants as well as representatives of aforementioned industry sectors, who were able to hear of proven results achieved in a very short time and based on reduced efforts for data acquisition. This was shown by using case studies of previously performed audits within the EINSTEIN II project. Last but not least trainees from the EINSTEIN I project recognised the achieved improvements and new features of EINSTEIN II. During the discussions, potentially interested users also expressed their interest in future trainings and audits performed by the EINSTEIN team.

Save thermal energy! EINSTEIN II offers cost-saving solutions to an Italian food company

VIS Srl., an Italian food company located in Valtellina (Northern Italy) at the foot of the Alps, produces about 2.000 tons of jam per year consuming about 2.000 MWh of fuel oil and about 500 MWh of electricity. Around 86% of the final energy consumption is for thermal (heating and cooling) final uses.

Jam is obtained from the frozen fruit which is periodically delivered to the company in tracks at -20ºC, and then stored in two refrigeration chambers. The fruit is extracted from the chambers, selected, crushed and placed in vessels. Then, it is cooked at low temperature and concentrated by vacuum evaporation. Jam is bottled, and the pots are then pasteurized and cooled down. Heat is also required for cleaning and space heating.

 

Figure 1. VIS Srl. Overview of the production hall


The heat consumed in the company is generated in two fuel oil fired steam boilers. The equipments are quite old, not insulated and stop frequently for maintaining. A fuel shift towards natural gas or district heating was envisaged by the owner of the company, but not implemented due to the distance between the company production site and both local existing grids.

Cooling at low temperature is provided by electrically driven chillers for the freezing chambers while groundwater is currently used to condensate the vapour produced during the vacuum concentration and to cool down the jam pots after the pasteurisation process.

According the EINSTEIN integrated approach, the alternative scenario generated with the support of the EINSTEIN software tool includes demand- and supply-side energy and economic saving measures.

In particular, it combines:

  • The optimisation of the pasteurisation and the post-pasteurisation (cooling) processes by reducing the unnecessary convection currents among the different tunnel sections.
  • The optimisation of the concentrators by direct coupling of the vacuum evaporation process to a mechanical vapour re-compression (MVR) system (nominal capacity: 182 kWth) for internal heat recovery.
  • A heat exchanger network (nominal capacity: 215 kW) to recover the sensible heat content of the cleaning waste water and of the concentration outflow to pre-heat the process and boiler feed-up water.
  • The fuel (oil) substitution and a new heating supply system including a biomass (wood chips) steam generator (nominal capacity: 1 MW) and a solar thermal flat plate collectors plant (nominal capacity: 60 kW) for process water pre-heating.

These measures together allow saving 57 % of the current primary energy consumption and 41 % of the current operating costs. Moreover, their implementation would contribute to reduce significantly the actual groundwater use for process cooling (saving estimated: 78%).

Release of EINSTEIN Version 2.1

We are happy to announce the 2.1 release of EINSTEIN. This release is an intermediate result of ongoing work in the Framework of the project IEE-EINSTEIN-II. It contains stability improvements and improvements to existing features.

Since version 2.0 the following new features were introduced:

  • introduction of thermal chillers as an equipment type
  • a separate treatment of air handling in buildings
  • Bulgarian as a new language for the GUI and the report generation

Since version 2.0 the following improvements were made:

  • differentiation between indoor temperature and heating system temperature
  • differentiation between process temperature and minimum supply temperature to processes in general
  • a flow chart input for process and pipe parameters for an easier understanding of the meaning of the parameters.
  • the possibility to connect heat exchangers as a low temperature heat source to heat pumps.
  • improved consistency checks of process temperatures
  • a speed up of the heat pump simulation code
  • updates of the French translation
  • updated technical documentation
  • several improvements to the GUI
  • fixes for several crash bugs in the simulation code
  • and a lot of the usual small bug fixes

The Software EINSTEIN 2.1 can be downloaded from: http://sourceforge.net/projects/einstein/files/einstein/EINSTEIN_2.1/

There you can find an installer executable for MS Windows that offers a simple and quick installation:

  • EINSTEIN_2.1-Installer.exe: a bundle installer for MS-Windows 7, Vista and XP that contains not only EINSTEIN but the MySQL server, a Python environment and all dependencies in one installer.
  • EINSTEIN_2.1.zip: is only EINSTEIN. If you’re comfortable with setting up the data base and providing the necessary Python environment by yourself, this variant offers the smallest download size. It is also the most sensible choice for users on a different computing platform than MS-Windows.

EINSTEIN 2.1 can be used as an update to existing Einstein installations of any version. An update from 2.1 prereleases is recommended.

What did our trainees think of our EINSTEIN introductory training courses?

This article provides a brief snapshot of the feedback we received from our training participants in 10 countries and 13 individual four-day courses in the series of EINSTEIN II introductory thermal energy auditing trainings.

The largest proportion of trainees attending our courses came from the consultancy sector, followed by university or research institutes. It is important to note that from the largest number of SMEs were often self-employed consultants.

We were happy to see that on overall terms, feedback has been positive with some room for improvement:

  • 68% agreed or strongly agreed that they will be able to make practical use of what they learned in the introductory training
  • 69% agreed or strongly agreed that as a result of the course they will be able to use the software in the future
  • 65% agreed or strongly agreed that the methodology and the software tool would be useful in their day-to-day work
  • 80% agreed or strongly agreed that the training helped them identify additional training/learning needs

Regarding the fundamental 1-day refresher training day we received a mixed response, with some trainees finding it very useful, whilst others felt they were already familiar with the content.

In terms of improving the content of the training course, the leading suggestion was to increase the interactive aspect of the course in the practical use the tool.

Partner case study : EINSTEIN II training courses in Ireland

The EINSTEIN introductory thermal energy auditing training course was held in Cork in May 2011. The training was carried out by Bettina Muster and Jürgen Fluch of AEE, Austria, assisted by Eileen O’Leary of CIT. All participants at the course were professionals from industry or consultancies. There was also good participation, and favourable feedback, on the optional one-day training on thermal energy fundamentals, which was carried out by Dermot Cunningham and Eileen O’Leary of CIT.

CIT hosted advanced EINSTEIN thermal energy auditing training during November 2011, with some of the returned participants from the introductory course held earlier in the year. This included people from the dairy and food industry. The training was carried out by Jürgen Fluch of AEE, Austria. Feedback was positive and included: “Generally course was very well presented and organised”; “The user interface was much improved on previous version”. One participant indicated the most valuable aspect of the advanced training course was “becoming more familiar with the software and more comfortable with its use”.

EINSTEIN II supports energy efficiency in Spanish businesses

The Madrid Chamber of Commerce and Industry (COCIM) held two National Conferences to improve energy efficiency in businesses and encourage the use of the Einstein tool kit.

The first National Conference, held on the 13th December 2010, was entitled "At the forefront of energy efficiency in business", and attracted a total of 36 companies.

The event was held in collaboration with the Directorate General of Industry, Energy and Mines of the Madrid Community, the IDAE (Institute of diversification to Save Energy) and AENOR (Spanish Association for Standardisation and Certification), as well as companies specialising in various energy efficiency techniques.

The Conference aimed to achieve three main objectives:

  • Disseminate policies on energy efficiency via the presentation of the latest legislative proposals for cogeneration and energy plans and aid from the Madrid Community to support companies in improving their energy efficiency.
  • Raise awareness of the importance and the advantages gained in conducting energy audits and the use of energy saving technologies, as well as state the benefits of standardisation.
  • Describe the actions carried out within the EINSTEIN II project.

The Madrid Company innovation example

The second National Conference, held on 19th October 2011, was entitled "The Madrid Company to innovate in energy efficiency’’, and attracted a total of 30 companies.

The conference was opened by D. Vicente Peris Ribera, President of the Committee on Industry and Environment, and was moderated by Ms. Maria Encinas, Deputy Manager of Industry, both of Madrid Chamber of Commerce and Industry.

Prominent speakers also included representatives from the IDAE (Institute of diversification to Save Energy), the Department of Industry, Energy and Mines of the Madrid Community and ANESE (Association of Energy Service Companies).

The Conference took the form of two round tables, which analysed on one hand the energy policies and energy efficiency grants available to businesses, and on the other, the EINSTEIN thermal audit tool kit and business case.

The main objectives of the Conference were to:

  • Disseminate the national policies on energy efficiency with the latest presentations of legislative proposals and energy plans. The assistance of the Madrid Community to carry out actions related to energy efficiency was also presented.
  • Present the methodology and the Einstein tool kit, as well as the benefits obtained from the optimal management of thermal energy in companies.
  • Present real case studies from companies involved in the EINSTEIN project II.

During the conference the companies expressed an increased interest and engaged in an active discussion on the utility and management of a productive tool, analysing the positive and negative aspects throughout an audit.

One of the most positive results from the day was the increased interest from delegates to participate in future training courses held by EINSTEIN II, possibly held in early 2012.

How Green is your Brewery ? The UK perspective in EINSTEIN II

On 25th November 2011, the West Midlands European Centre organised, in collaboration with AEE INTEC from Austria and the Campden Brewery Research Institute (BRI), an EINSTEIN II national conference focusing on thermal energy efficiency in breweries.

Requiring high temperatures for the brewing and malting process, breweries are very intensive users of thermal energy. Through its sophisticated methodology, the EINSTEIN II tool kit for thermal energy auditing can assess saving potentials and offer integrated energy-efficient solutions. Possibilities range from re-using the waste heat for pre-heating the wort to introducing solar process heat to the industrial energy systems of breweries.

Source: AEE INTEC

Showing high interest in EINSTEIN II and its trainings, 24 brewery companies took this excellent opportunity to learn about ways to decrease the energy demand and use renewable energy sources in the brewery industry. The results of different case studies and projects in the following fields were presented:

  • Thermal energy reduction of brewing and malting processes,
  • Improving of hot water storage management especially between brewhouse and packaging,
  • The heat supply by renewable energy sources like bio-gas from spent grain and solar process heat.
