Foster Wheeler

About Company

Foster Wheeler AG (formerly Foster Wheeler Inc.) was a Swiss global engineering conglomerate with its principal executive offices in Reading, UK[1] and its registered office in Baar, Canton of Zug, Switzerland.[2] Foster Wheeler was added to the NASDAQ-100 on 12 July 2007. On 13 November 2014 Foster Wheeler merged with Amec plc to form Amec Foster Wheeler. The resultant company was acquired by and merged into Wood Group in October 2017.

Foster Wheeler was an equipment supplier that served engineering, construction and power generation industries. The company was formed in 1927 when Power Specialty merged with Wheeler Condenser & Engineering Company.

Foster Wheeler's Milan-based subsidiary Foster Wheeler Italiana S.p.A. was awarded an engineering, procurement and construction contract for the addition of a second processing line at Lomellina Energia's existing waste-to-energy plant at Parona, Italy. This expansion project will allow the plant to process an additional 180,000 tons per year of RDF, producing an additional 19 MW of power, which will be sold to the Italian national grid under a long-term power purchase agreement with GRTN (the Italian National Grid operator). The existing plant, the first of its kind in Europe, is an integrated facility for recyclable materials recovery and refuse derived fuel (RDF) production, composting and electricity generation. It processes 200,000 tons per year of municipal solid waste (MSW), converting approximately 60 percent of the MSW into RDF, which is then combusted, generating 15 MW of electric power. Foster Wheeler's overall scope also includes a steam turbine and generator, a steam condenser, flue gas treatment, upgrading of the existing waste pre-treatment system and auxiliary facilities. The contract value exceeds US$130 million (110 million Euros) and commercial operation is scheduled for September 2007.

Title: Method of and an apparatus for gasifying carbonaceous material Publication: 2011-05-24 Coverage: US, EP, FI & WO Assignee: Foster Wheeler

• A method of and an apparatus for gasifying carbonaceous material, the apparatus including a gasification reactor, to which oxygen-containing primary gas and secondary gasification gas are introduced, whereby a portion of the material to be gasified is gasified to product gas, residual carbon contained in the fly ash extracted from the product gas is combusted in a cyclone combustor, and the exhaust gas from the cyclone combustor is guided to above the bottom level of the gasification reactor to act as secondary gasification gas.
• The gasifier may operate substantially at an atmospheric pressure or it may be a pressurized gasifier arranged inside a pressure vessel. A fluidized bed gasifier in accordance with the invention is preferably a circulating fluidized bed gasifier, but it may also be a slow fluidized bed gasifier, i.e., a bubble bed gasifier. The invention is especially applicable for gasification of bio fuels and waste-derived fuels, but it may also be used for gasifying coal and other carbonaceous fuels.

Covanta Energy

About Company

Covanta Energy, LLC operates as waste management company. The Company offers waste management and consulting, as well as onsite services, assured destruction, recycling and de-packaging solutions, liquid waste management, and treatment services. Covanta Energy serves customers worldwide.

Covanta Energy is an internationally recognized owner and operator of Energy-from-Waste and power generation projects. Covanta Energy's Energy-from-Waste facilities convert municipal solid waste into renewable energy for numerous communities, predominantly in the United States. The company owns/operates over 40 EfW facilities in the United States that safely convert 20 million tons a year of municipal solid waste into clean, renewable energy for communities throughout the country.

Covanta, a leader in sustainable materials management and a premier provider of environmental solutions for businesses and communities, announced tha the Covanta Alexandria Waste-to-Energy facility recently completed planned enhancements to its state-of-the-art pollution control technology. The goal is to further reduce nitrogen oxide (NOx) emissions, thereby helping to protect the environment.

The Alexandria based Waste-to-Energy facility serves 400,000 residents and businesses in the City of Alexandria and Arlington County. It provides reliable and sustainable waste management by combusting non-hazardous household waste at high temperatures, which then generates steam for renewable electricity production. In this way, Covanta processes and converts more than 350,000 tons of waste that would otherwise end up in landfills into energy.

With installation of Covanta's proprietary Low NOx (LN) technology now complete, nitrogen oxide emissions have been reduced by nearly 50%. The effort was part of a multi-year project at the Covanta Alexandria-Arlington facility. By reducing the waste put in landfills, Covanta Alexandria has cut greenhouse gas emissions by 331,000 tons of carbon dioxide. That's the same as taking 65,000 passenger vehicles off the road for one year.

• The present invention relates to a gasification combustion systems and methods that control the rate of gasification or combustion. By controlling the oxidant supply and temperature of gasification or combustion, the system can more efficiently burn refuse and reduce the emission of harmful products (gases and/or solids) into the atmosphere. Additionally, by controlling the rate and temperature of gasification or combustion, a more durable system can be created which will be more efficient in terms of energy conversion and flue gas processing after MSW thermal treatment.
• Embodiments of the present invention may employ a moving grate that enables the movement of waste through the combustion chamber and thus allows complete combustion of the waste.

Hyundai

About Company

Waste-to-hydrogen, plastic-to-hydrogen production through electrolysis are the areas in which Hyundai Motor Group is deeply involved. Waste that burdens our planet can be used as feedstock to create hydrogen energy, creating a double positive effect as we resolve waste pollution along the way. Moreover, we can produce green hydrogen through electrolysis, which does not emit polluting gases either during combustion or during production.

Green hydrogen production through water electrolysis utilizes power generated by renewable energy sources, which does not emit polluting gases either during combustion or production.

The Hyundai Waste Energy Recovery Co-Generation Project Phase II

Hyundai Waste Energy Recovery Co-generation Project Phase II The Hyundai Waste Energy Recovery Co-generation Project Phase II is a 400MW cogeneration plant located at Dangjin Hyundai Steel Mill. This project, developed by Hyundai Green Power CO., Ltd., utilizes surplus waste gases including BFG (Blast Furnace Gas), COG (Coke Oven Gas), and LDG (Converter Gas) generated by Dangjin Hyundai Steel Mill to generate electricity. By recycling the waste gases, the steel mill is able to reduce emissions and minimize waste.

Key Highlights:

• The project generates approximately 2,306,076MWh of electricity, which is sent to the power grid.
• Steam is produced and sent to Hyundai Steel Mill, reducing their need for additional energy sources.
• Without this project, the waste gases would be emitted to the atmosphere after incineration.

This project is important because it reduces emissions and waste while generating valuable energy. By utilizing otherwise wasted resources, the Hyundai Waste Energy Recovery Co-generation Project Phase II is a sustainable solution for energy production.
