Danish Consortia

We experienced challenges when we tried to bring a single Danish equipment product to biogas projects in the Chinese market. The up-stream and the down-stream equipment installations or the process design do not completely match the quality or the efficiency of the Danish product. By establishing a Danish consortium which can provide with total Danish-featured solutions for the Chinese clients, we can bring the value of the Danish products into full play in a project. As what we have learned from our Chinese partners, a total solution is more convenient for them in project bidding and implementaton. Secondly, working together as a consortium, the participant Danish companies can to a large extent reduce the cost for market development in China. And thirdly, the workload for making offers and for contract negotiation can be reduced significantly. 

For the time being, we have established the following two consortia, which are called 'Straw-for-Heating Consortium' and 'Biomass-for-Biogas Consortium', respectly. We are on the way to establish three consortia in the water sector, which will be called 'Smart-Drinking-Water-Supply Consortium', 'Smart-Drainage-Management Consortium', and 'WWTP-Upgrading Consortium', respectively.

Straw-for-Heating Consortium

This consortium, for time being, includes the following companies and knowledge institute:

  1. C.F.Nielsen A/S
  2. Alcon A/S
  3. Teldust A/S
  4. Justsen Energiteknik A/S
  5. Engineering Department, Aarhus University

In the urban areas in China, only processed straw is allowed to be used as fuel for boilers due to the requirement by the stringent emission standards. With C.F.Nielsen A/S in the consortium, we can help our clients converting straw to briquettes. Alcon boiler is very much suitable to the schools, hospitals, farms and other organizations in the rural areas, where small scale boilers are suitable. Teldust filter can ensure that Alcon boiler meets the Chinese emission standards. Justsen boiler system can be used for large scale, and for both hot water and for steam production. Aarhus university can always provide with assistance for with technology development. 

This consortium can provide, for the local district heating operation companies and for the local municipalities, with solutions for both small scale and large scale projects, for projects both in the urban and in the rural areas, and with commitment of the Chinese emission standards.

C.F. Nielsen A/S produces the worlds’ largest range of briquetting presses ranging from 200 kg to more than 5.000 kg per hour. The presses are sold all over the world for different biomasses, including agricultural straw, into briquette. C.F.Nielsen briquetteing presses are characterised by high output, high efficiency, low energy consumption, and cost on wear parts.  >>

Alcon A/S is a company, which manufactures high efficient, manually stocked straw boilers with outputs in the range from 30kW to 12,000 kW. Under the support of the Midtnet Kina Program, Alcon A/S has modified its boiler in order to adapt to the charisterastics of the Chinese local maize straw, climate conditions and the environmental standards. >>

Teldust A/S is a producer of high efficienct dust filters dedicated to biomass boiler. In China, biomass boilers must be equipped with dust removal devices, due to stringent emission standards. Teldust A/S is a partner of our Midtnet Kina project, through which Teldust filter is coupled to Alcon boiler. >>

Justsen Energiteknik A/S is an original equipment manufacturer (OEM) specializing in biomass fueled boiler systems. The company can offer high quality, high efficient and automatically-stocked biomass boilers with outputs in the range from hundreds kW  up to 20 MW and larger. >>

The Engineering Department of Aarhus University is a knowledge institute specialized in improving the biomass combustion efficiency and reducing emissions for biomass boilers. In our Midtnet Kina project, Aarhus University is responsible for providing innovation and testing of Alcon boiler. >>

Biomass-for-Biogas Consortium

This consortium is organized for providing Danish urban waste treatment solutions for the Chinese market. For the time being, it includes the following companies:

  1. Gemidan Ecogi A/S

  2. Renew Energy A/S

  3. Westcome Heat Exchangers A/S
  4. NISSEN Energy A/S

In China, urban biomass includes among others restaurant waste, the organic fraction of household waste, residuals from food and beverage business, sludge from wastewater treatment plant. Such waste streams can be large in quantity in cities where population is huge. If not disposed, the wastes will impose severe threat to the environment.

In Denmark, urban biomass is disposed through pre-treatment and anaerobic digestion for biogas and fertilizer production. This is the most sustainable way and the technology has been well established and matured in Denmark.

In China, it is required that the municipalities take the responsibility  to have urban biomass disposed before discharge. Recently, a new regulation, that requests the organic fraction in household waste has to be souce-sorted in big cities, has  been promulgated. This means increasing amount of urban biomass is available for biogas and fertilizer production. This gives opportunities for the relevant Danish companies.

Gemidan Ecogi A/S develops, supplies and operates processing technologies for the treating and recycling of food waste from households, businesses and industry. Its Ecogi press is able to recover 95% of the organic material from food wastes, to a pulp which is > 99.9% free from physical contamination for conversion into biogas using anaerobic digestion (AD). The process is designed to minimize operating costs through a fully computerised control system and reduced maintenance requirements.  >>

Renew Energy A/S is an experienced engineering and consulting company, which undertakes the whole turnkey contract of the biogas project from the very beginning to the handover of the plant. Renew Energy A/S has completed a number of biogas plants including the world largest state-of-the-art ecological biogas plant, Månsson biogas plant, in Denmark.  >>

Westcome Heat Exchanger A/S is an innovative company, which has developed and patented high viscosity heat exchanger with the highest efficiency and the lowest pressure loss among comparable products. Such equipment is of vital importance to recover the heat in the digester effluent in order to keep the process stablity and the economy of a biogas plant.  >> 

NISSEN energy A/S designs, constructs, installs high quality and high efficiency CHP units, as well as complete CHP plants, which convert biogas (or nature gas) into electricity and heat. The electricity can be sold to the grid. The heat is necessary for compensating the heat loss in the digester system to maitain the process temprature. The surplus heat can be sold to district heating.  >>

Smart-Drinking-Water-Supply Consortium

In Denmark, the water utilities use digital and intelligent software system to manage the drinking water production works, the pipelines, and the boosting pump stations. The Danish drinking water system are featured with the following highlights:

  1. The state had required that all utilities should have digital mangement system before June 30, 2023. Now, each of the water utilities has its own digital and intelligent sofware mangement platform. 
  2. Smart meters, and sensors for water level, pressure and flow rate extensively used in the drinking water system.
  3. Electronic modules and actuators for controlling pumps and valves are extensively used in the drinking water system.
  4. Realtime online monitoring, and data collection and analysis make it possible for having intelligent and automatic control over the whole drinking water system.
  5. The drinking water supply is operated as a demand driven distribution system, which can save energy, reduce leakage, and lower fatigue losses of the pipelines.
  6. The Danish technologies on detection of leak, pipe reparation and renovaiton are very strong.
  7. With help of digital and intelligent mangement, Denmark has a national average of the non-revenual water of about 7 %. Some of the utilities has a NRW rate lower than 5%.
  8. Low energy consumption for operating the drinking water system contributes energy-neutral and CO2 neutral of the water utilities. Some of the Danish water utilities have achieved energy-neutral.

We are now calling for relevant Danish companies to participate this consortium.

Smart-Drainage-Management Consortium

The Danish drainage system is complete and efficient. It is very common that the water utilities use digital and intelligent software system to manage the drainage system to make sure that sewage is transported to the wastewater water treatment plant as fast as possible. The recent efforts are separating rain water from wastewater, and making climate adaption to aviod urban flooding. The following are the highlights of the Danish drainage system:

  1. Application of digital platform to register the data of the drainage system (pipelines and ancillary facilities) to achieve digital and visual management of company assets.
  2. Snsors (sensing water pressure, level, flow, leakage points, and etc.), electrical control modules and actuators (operating valves, gates, and etc.) as well as the design of corresponding algorithms, data transmission, early warning and alarm software systems are well established.
  3. Establishment of software and monitoring systems for drainage pipe network overflow and for external water intrusion.
  4. Intelligent control of pump stations (remote and automatic control, energy-saving, reversal flux when blocked, early warning and alarm of failure).
  5. The layout of urban flood control basins and establishment of intelligent operation software systems.
  6. Setups to prevent backflow from the water bodies (rivers, the lakes, the sea, and etc.) during heavy rain, by automatic control of check valves and gates, and by early warning and alarm software system.
  7. A software system for intelligent operation of septic tanks, drainage pumping stations and flood control reservoirs according to the weather forecast information.

8. Improve occupational safety and maintenance of drainage facilities through

     online H2S monitoring and provide early warning of safety hazards.

We are now calling for relevant Danish companies to participate this consortium.

WWTP-Upgrading Consortium

The wastewater treatment plants in Denmark were mainly built in the 1970-80's. Benefited by the innovaltive technological development, the process technologies of the WWTPs have been world-leading since they were built. Even in the 1970's, digital and automation technologies were used in the WWTPs. Along with more and more strigent requirements on nitorgen and phosphorus removal, on reduction of energy and chemical consumption, and on emission of CH4 and N2O, the water utilities have been continuously upgrading their WWTPs. Today, about 95% of the wastewater in this country is collected and treated in the high-efficiency and low-energy and low chemical consumption WWTPs. More over, many of these WWTPs have achieved energy neutral or even energy surplus. The following are the highlights of the Danish WWTPs:

  1. Amonia-based areation, which saves a lot of energy in comparison with the conventional desolved oxygent-based aeration.
  2. Biological nitrogen removal is enhanced by using side-stream Bio-P and by precise chemical dosage.
  3. High-efficient sludge condensation, dewatering and stabilization.
  4. Biogas utilization for green energy production.
  5. The process opertion is based on real-time online monitoring and analysis, and real-time automatic control.
  6. High efficient, robust and program-controllable equipment installations are used in the WWTPs.

We are now calling for relevant Danish companies to participate this consortium.
