Steinmüller Babcock builds seawater flue gas desulphurisation plants in Cyprus

Gummersbach, 29. Oktober 2018. HZI Steinmüller GmbH, based in Gummersbach/Germany has been awarded the contract for two seawater flue gas desulphurisation plants at the Vasilikos power plant in Cyprus, after succeeding in an international tender. Leader of the EPC consortium created for this purpose is TERNA SA, Athens, customer is the operator of the facility, the Electricity Authority of Cyprus. The scope of supply and delivery for Steinmüller Babcock includes basic and detail engineering as well as key components.

The Vasilikos power plant is located 25 km east of Limassol, it was built between 1999 and 2012 and generates 865 MWel. The first three lines operate on heavy fuel oil, whereas the other two are combined cycle units in a 2+1 configuration, operating on distillate fuel oil. The plant supplies 40% of the electrical energy needed in Cyprus.  After installation of the flue gas desulphurisation plants on lines 1 and 2, the power plant meets the highest EU directives for air quality. Most of the components are installed during operation, only for the final work the lines are shut down for a few weeks.  The commissioning of the two flue gas cleaning plants is planned for early summer 2020.

Seawater flue gas desulphurisation plants use seawater as absorption medium instead of limestone, which is commonly used in wet washing processes. The sulphur dioxide contained in the flue gases is dissolved in the seawater and forms sulphite and hydrogen sulphite. These compounds are neutralised by carbonates and bicarbonates, which are natural constituents in seawater. In a ventilation basin ambient air is supplied, the oxygen contained oxidizes the sulphur compounds to sulphate, a natural component of seawater. The seawater used for the process is used twice in Vasilikos, first as cooling water, then for flue gas cleaning. The water, which has been returned to the sea, fulfils all defined discharge conditions. The process does not generate any residues. Despite the amazing simplicity, the process achieves sulphur dioxide deposits of over 95%. The flue gas desulphurisation plants will significantly reduce odour emissions and pollutants, and they will also contribute to the further dedusting of flue gases as a supplement to existing electrostatic precipitators.

Steinmüller Babcock licenses technology for China

Gummersbach, 3. September 2018. HZI Steinmüller GmbH, based in Gummersbach, has once again allocated a know-how license for the use of one of its key technologies in the Chinese market. An agreement has been reached with the Düsseldorf-based company Aetna International GmbH, which allows Aetna to set up plants for the thermal treatment of hazardous and industrial waste by a local subsidiary in China.

The subject of the contract is the so-called “rotary kiln technology” which ensures with its very high temperatures a safe destruction of all organic substances. At the same time energy in the form of steam or electricity can be obtained from polluted, contaminated or mixed waste. The technology will make it possible to comply with the stringent European directives on hazardous waste treatment in future also in China. Aetna International will build a first plant in Huantai County in Shandong Province, China, in which the hazardous waste from local chemical companies will be disposed of in an environmentally sound manner. The project start will be already within the next few weeks. Aetna International will get technological support for the application of the technology by Steinmüller Babcock. In future, Aetna will distribute and realise the technology independently.

On August 20th, the official presentation of the cooperation took place in Duesseldorf. In addition to the representatives of Steinmüller Babcock, Aetna International and Dongyue Group, high-ranking guests from China were also present, such as Jiangfeng Bian, the head of the People’s Government of Huantai County, Dong Lu, the director of the Economy and Information Bureau of Huantai County, and representatives of the Huantai-based companies and commercial agencies.

HZI Steinmüller and Wallstein increase energy efficiency at RZR Herten

Gummersbach, 21th June 2018. HZI Steinmüller GmbH based in Gummersbach and Wallstein GmbH from Recklinghausen have received orders from AGR Abfallentsorgungs-Gesellschaft Ruhrgebiet mbH and its subsidiary RZR II Herten GmbH for the construction of a heat recovery system for the four municipal waste incineration lines of the RZR Herten waste power plant.

RZR Herten is already very energy-efficient and uses the energy from municipal and commercial waste to generate electricity and district heating. Each of the four municipal waste incineration lines will be equipped with an additional heat exchanger on the flue gas side in order to make efficient use of energy that was previously unusable. The residual heat recovered in this way is fed into the district heating grid “Fernwärmeschiene Ruhr”. The new system increases both the efficiency of the entire plant and operational flexibility.

While Wallstein Ingenieur GmbH as consortium leader is responsible for the process engineering system guarantee and delivery of the corrosion-resistant heat exchangers, the scope of supply and services of HZI Steinmüller GmbH includes the remaining system components, their system integration and complete assembly. The project is scheduled for completion by December 2018. The scheduled revision phases of the four municipal waste incineration lines will be used for installation.

HZI Steinmüller builds waste treatment centre in San Sebastian

The capital of the province of Gipuzkoa in Basque. The contracting authority is a Spanish project company led by Urbaser S.A.. The project company is commissioned by the local waste collector Gipuzkoako Hondakinen Kudeaketa SA to finance, construct and operate the waste treatment centre. HZI Steinmüller as the leader of the general contractor consortium will coordinate the planning, design, procurement, erection and commissioning of the complete complex and will erect the turnkey thermal waste treatment plant.

The concept of the waste treatment plant includes a mechanical-biological treatment stage as well as two waste incineration lines with an annual capacity of 200,000 tonnes of municipal waste. The energy generated is enough to provide electrical power to more than 45,000 households. After completion in 2019, the plant will be one of the cleanest waste treatment plants in the world. This is achieved by a three-stage flue gas cleaning concept. In the first stage, sulphur dioxide and other acidic gases are separated by means of a dry sorption process based on bicarbonate. A second stage eliminates nitrogen oxides by the use of SCR catalysts. The third stage reduces the remaining acidic pollutants as well as dioxins and furans to a minimum via a lime hydrate-based sorption process.

The mechanical-biological treatment and the thermal utilisation will replace the landfill of the waste in the currently used landfill Lapatx. The investment volume of the waste treatment centre is € 217 million, the total project value including financing and 32-year operation is about € 770 million. More information at

EfW plant in Delfzijl to be expanded by a 3rd waste incineration line

In Delfzijl (Netherlands) to the traditional Gummersbach company HZI Steinmüller (SBEng). The scope of the SBEng contract includes the planning and construction of a boiler including a combustion grate and ancillary facilities. Installation will begin in June 2017 with completion scheduled for only 16 months later in October 2018.

This additional line with a capacity of 192,000 tons per year is solely intended for the incineration of refuse derived fuel (RDF). These fuels, especially treated from commercial and industrial waste, possess a significantly higher calorific value than conventional domestic waste. Compared to the generation of energy with fossil fuels, the use of RDF to generate energy represents a cost-effective and environmentally friendly alternative. The steam generated from the plant is intended to supply the energy requirements of, for example, the companies operating in the neighbouring Oosterhorn Industrial Park. The Delfzijl location offers distinct advantages: firstly, the existing infrastructure is made use of in such ways that enables delivery of the waste by ship, rail or truck, while secondly, the supply routes for the process steam to the nearby industrial enterprises are particularly short. The industry partners will thus draw environmentally friendly energy, generated directly at the location.

The EEW-Group has been planning, building and operating waste disposal plants for over 25 years, setting Europe-wide standards in the process. As the market leader in Germany and ranked one of the top ten in the world, the company today possesses the biggest park of installations in Germany generating power from the thermal recycling of waste. With the Delfzijl contract, Steinmüller Babcock is building on the longstanding successful cooperation with EEW. This company has already put its trust in the expertise of SBENG with the EfW plant in Heringen as well as the ongoing service activities at several locations.

HZI Steinmüller receives order for WtE plant Högbytorp

Gummersbach, 8 March 2017. HZI Steinmüller GmbH, based in Gummersbach, Germany, won the bidding process to build the boiler and furnace unit for a new waste utilisation plant in northwest Stockholm. The client is E.ON Värme Sverige AB, the Swedish subsidiary of the German E.ON Concern. The single-line waste-to-energy plant, with a performance of 100 MWth, will treat municipal and industrial waste and later supply electricity and district heating to the region. More than 80% of the annual heating needs of the E.ON district heating network will be covered by the WtE plant Högbytorp in the future. Commissioning is planned for the end of 2019.

HZI Steinmüller convinced with a technical concept that combined a tailored, sophisticated solution with a good price. This is already the second contract from E.ON Värme Sverige AB for the Gummersbach company, after the energetic optimisation of a waste-to-energy plant in Norrköping, Sweden. The contract for HZI Steinmüller encompasses the engineering, construction and delivery of the complete waste incineration unit, including the combustion grate, dry deslagging, boilers and other components of the water-steam cycle, as well as the boiler house and the façades.

The WtE plant Högbytorp is part of a location initiative for the sustainable development of the urban district of Järfälla and Upplands Bro in northwest Stockholm. It will be one of the largest thermal waste utilisation plants in Sweden. Household and commercial waste will be used. The forward moving grate installed by Steinmüller with 4 tracks and a width of more than 12 metres, is the largest that HZI Steinmüller will have delivered in its history to date. The boiler is also impressive, with a performance of 100 MWth. The combustion capacity of the plant is designed for 45 tons per hour. Furthermore, with this new plant construction, an innovative dry deslagging concept will be used for the first time in Sweden, which allows a much higher recovery of resources from slag. Thus the waste incineration plant will not only utilise the energy of the waste, but will also make a significant contribution to material recycling.

The focus of energy generation at the waste-to-energy plant Högbytorp will be on the provision of district heating. The goal is to merge the three currently existing district heating networks of the surrounding municipalities, which are currently being supplied by small older heating plants, into a large network that will be fed in an environmentally manner with energy from waste. More than 80% of the annual heating needs of the new large district heating network will be generated in future by the thermal waste utilisation plant in Högbytorp.

After its completion, the WtE plant in Högbytorp will be visible from afar as a deliberately designed landmark, even from the Swedish E18 motorway. “Typically Swedish”, the plant will receive an impressive, mostly transparent façade. The famous Stockholm architecture practice Scheiwiller Svensson Arkitektkontor AB is responsible, which also designed the project “Filmstaden Mall of Scandinavia” in Solna, among many others.

For HZI Steinmüller, the on-site operative construction phase starts in March 2018, the erection of the boiler is planned for May 2018.

Ceremonial contract signing for new combined heat and power plant in Lithuania

Gummersbach, 29. September 2016. Last Thursday, the ceremonial contract signing for a combined heat and power plant (CHP) took place in Vilnius (Lithuania), which is expected to go into operation at the beginning of 2019. This event was attended not only by representatives of the customer, but also, in addition to the Lithuanian Prime Minister Algirdas Butkevičius, by numerous high-ranking, distinguished guests from politics, administration and business. The significance of this project was also underlined by the participation of the Permanent Representative of the Federal Republic of Germany, Michael Morgenstern.

In the procurement process, the customer, UAB Vilniaus kogeneracinė jėgainė, a subsidiary of the state controlled energy company “Lietuvos Energija”, decided in favour of the consortium led by HZI Steinmüller GmbH with the partners Budimex S.A. and Kauno dujotiekio statyba. The convincing argument of the consortium was its technical expertise and the development of a customised solution – enabling it to do justice to the high status associated with this project, which has been classified as a “project of national economic significance” by the Lithuanian Government and is funded by the European Union.

The whole project comprises the construction of a total of three lines to generate electricity and district heating: a waste incineration line with grate technology (Lot 1) as well as two biomass lines with fluidised bed technology (Lot 2). The contract of the consortium led by HZI Steinmüller for Lot 1, with an order value of some 180 million Euros, contains not only the complete waste incineration line, which also includes a connection to an existing mechanical-biological treatment plant, but also all higher-level systems for the entire plant.

Within the consortium, the delivery share to be provided by HZI Steinmüller comprises the complete process technology for the waste incineration – beginning with the waste input via the combustion system, the boiler, the flue gas cleaning and the flue gas condensation through to the chimney. Furthermore, the feedwater system, the process control system and the medium and low-voltage switchgears are also included. The Polish construction company Budimex will undertake the construction part as well as the water-steam cycle and the high-voltage connection. The Lithuanian company Kauno dujotiekio statyba will be responsible for the local planning, the district heating pipelines and the connection to the external infrastructure.

The cogeneration plant, designed for a high degree of efficiency, will help to save on fossil fuels by the thermal recycling of the waste and ensure the future supply of electricity (90 MW) and district heating (230 MW) to the population of the region.

For HZI Steinmüller this project provides yet again the opportunity to demonstrate its turnkey expertise in international plant construction. For the EfW plant in Klaipeda commissioned in the spring of 2013 – not only the first of its kind in Lithuania, but in the whole of the Baltic region – HZI Steinmüller was responsible for the planning, delivery, installation and commissioning of the complete boiler and combustion plant as well as the associated anciliary facilities, thus enabling it to substantiate its capability in no uncertain terms.
