Launch of the Rotary Lobe Compressor
Delta Hybrid from Aerzen (Germany) is a synergy of blower and compressor technology. By combining the technical advantages of both concepts, it offers completely new possibilities for generating positive pressure or vacuum in air and neutral gas applications.
A total of 7 patents or patent applications currently make the Delta
Hybrid one of the most innovative products in compression technology. While low pressure applications call for the Roots- principle of isochoric compression, the screw compressor, with its internal compression, becomes the preferred choice for its energy efficiency in higher pressure ranges. The package concept is based on the well known and successful Aerzen Delta design (Delta Blower and Delta Screw) and has been systematically upgraded.
Carbon Dioxide Liquefaction
Carbon dioxide is consumed in many valuable applications such as carbonation of beverages, food preservation and chilling, cold chain management, transportation and water treatment. The British market is growing steadily and supply stability is critical for customer’s processes. To further enhance its supply infrastructure in the UK, Air Liquide, the European leader in the carbon dioxide market is investing in a new carbon dioxide recovery and liquefaction plant at the Wissington site of British Sugar.
The overall investment amounts to nearly €10 million.
The plant will be able to recover up to 70,000 tonnes of carbon dioxide per year coming from natural fermentation processes and is scheduled for commissioning in the summer of 2011. The bioethanol plant uses locally grown sugar beet as its primary feedstock and the recovered carbon dioxide will be purified and liquefied instead of being directly released into the atmosphere.
The investment adds to an existing plant in the North West of England and additional
sources in North East England and in Scotland. Located in Norfolk, the plant is well positioned and offers good proximity to numerous customers located in the South and East of England. Sylvie Villepontoux, Managing Director for Air Liquide UK, commented: “We are very pleased to develop this partnership with British Sugar. This new investment together with a reliable manufacturer such as British Sugar, enables Air Liquide to strengthen its supply chain and meet the growing needs of its customers. It will also significantly improve the whole supply chain for the British market and continues Air Liquide UK’s policy of targeted investments in growing markets.”
Gino De Jaegher, Managing Director for British Sugar UK & Ireland, commented: “We are delighted to partner with Air Liquide UK on this exciting project. As leaders within our respective markets, we can guarantee the secure supply of carbon dioxide competitively whilst creating value for carbon dioxide for both businesses within the UK. Once again, British Sugar clearly demonstrates our ability to transform all of our raw materials into sustainable products for the future.”

Recovering Energy from Waste without Landfilling or Incineration
Ze-gen, Inc., a US-based firm with plans to build their second commercial scale plant in the UK, has an answer to the problem of the economic viability of waste gasification. With its liquid metal gasification technology, Ze-gen can reliably produce tar-free synthesis gas from selected waste materials, including construction and demolition (C&D) wood waste. The company will exhibit at the "energy from biomass and waste" (EBW UK) on January 25 to 26, 2011 in London.
In the UK, 120 million tonnes of construction, demolition and excavation waste arise every year. This is around one third of the
country’s total waste arisings. Too much of the rubbish currently ends up on landfills which are a significant source of environmental damage. Once the discarded materials are in the ground they break down to form methane and carbon dioxide, two potent greenhouse gases.
Gasification of waste materials is not a new idea and so far commercial viability remained elusive. Ze-gen’s approach to the
technology is different in that its liquid metal gasifier results in extremely low thermal losses while ensuring tar-free synthesis gas (syngas). Syngas can be used to produce power, heat or liquid fuels.
"Ze-gen’s liquid metal gasification process has the potential to reduce the landfilling of valuable waste in the UK while simultaneously
generating renewable energy", comments Bill Davis, Founder and CEO of Boston, Massachusetts-based Ze-gen, Inc. "We look forward to sharing our approach at the EBW UK conference."
With his talk on "The Truth about Waste Gasification" Bill Davis will be the keynote speaker in the "Thermal Treatment" session at the EBW UK conference on January 25, 2011, 11:30-13:00 at the Royal Horticultural Halls & Conference Centre in London.

Envitec (Germany) is building two biogas plants in Latvia. “We are delighted that our international expansion has enabled us to undertake a project in Latvia which will certainly act as a kind of beacon for the entire region”, says Roel Slotman, the Executive Board member in charge of international sales at EnviTec Biogas AG. He adds that the Baltic country’s extensive farmland offers big potential for biogas and that the attractive feed-in tariff set by the Latvian government has created strong incentives for investment in biogas plants. “We expect that the market for biogas in Latvia will continue to evolve over the coming years and we are excited to be part of this development right from the start”, Roel Slotman said.
The sites for EnviTec’s first two biogas plants in Latvia are located in the western part of the country, not far from Liepaja, Latvia’s third largest city. The customer is the operator of a pig farm who has awarded EnviTec a contract for the construction of two plants rated for an electrical output of one megawatt each. The methane is converted into electricity in cogeneration plants whose heat output will serve to heat the sheds of his pig farms.
Latvia is among the EU countries whose local power stations
cannot cover their own electricity requirements. The Baltic republic is also dependent on natural gas imports. The country therefore intends to build local energy supplies through growing use of renewable energies. The feed-in remuneration paid for biogas amounts to the equivalent of between 18 and 22 cents per kilowatt hour.

Over a ten year operating period, energy costs equate to about 90% of the total Life Cycle Costs of a compressor. With this in mind, the Delta Hybrid was developed with the focus on increasing energy efficiency and achieving a significant reduction of energy costs and greenhouse gas emissions.
The ideal union of both rotary lobe blower and screw compressor technologies resulted in the Delta Hybrid, a future- oriented innovation that reduces the energy consumption by up to 15% compared to usual compressors.
A 3+3 twisted rotor profile is used for low pressures up to 800 mbar (12 psi) whereas a 3+4 rotor profile is used for pressures up to 1500 mbar (22 psi): a compressor with optimum efficiency can be selected for the needed pressure range. Optimised fluidic design of inlet and discharge ports provides for ideal flow conditions and reduced slippage. The inlet air is sucked in on the cold side of the package and discharge silencer isolation helps maintaining a low inlet temperature, therefore increasing the compression efficiency. Moreover, the belt-driven Delta Hybrid offers the significant advantage of exact sizing the greatest advantage comes from the energy that does not need to be used. In other words, a 5% excess in volume flow corresponds to a 5 % higher energy use.
