Metso solution brings added value to chemical recovery
Metso will perform replacement of a chemical recovery boiler for UBE Chemicals in Thailand. With Metso's solution, recovered chemicals can be combusted more efficiently, creating energy extraction benefits with minimal burden on environment. The total value of the order is above EUR 10 million and will be included in Energy and Environmental Technology's Q2/2011 orders received.
UBE Chemicals operation in Rayong, south of Bangkok in Thailand, is engaged in the production of nylon from raw materials. In the production process chemicals are released and can be combusted. The Metso delivery provides for an efficient combustion process solution of chemicals, and is based on Metso's recovery boiler concept used in the pulp- and paper industry. Metso's delivery brings value and efficiency to the innovative products and solutions UBE Group is offering to customers around the world.
"Our choice in Metso for this project is due to their innovative and efficient skills proven during earlier cooperation", says Watchara Pattananijnirudorn, Executive Vice President of UBE Chemicals in Thailand. "Metso has previously performed a similar replacement for UBE Chemicals in Spain when a new combustion plant for chemicals was installed with exceptional results."
In Thailand Metso is to replace the entire pressure vessel with a new designed incinerator to be situated within the existing structure. The current combustion process will be replaced with a complete and more efficient solution in terms of recovery and end combustion of chemicals. Commercial start-up and take over is scheduled for summer 2012.
UBE Group is a diversified manufacturer with a core focus on the chemical sector. With global presence, UBE's chemicals can be found in everything from digital electronics and consumer goods to automotive parts and pharmaceuticals. UBE also produces a wide range of products beyond the chemicals sector, supplying useful materials and goods such as cement, building materials and aluminum wheels.
Technical information
The new pressure vessel concept will utilize burners at two levels, were fuels are sprayed into the burning chamber section of the boiler. Combustion air is then added in a three level air system and the air ports are equipped with automatic rodding devices for remote operation. The firing technique is significantly reducing the amount of sodium carbonate carry over in flue gases and heat is recovered in the heat absorbing surfaces consisting of water screens, convection, and economizer. The various heat absorption areas are cleaned by soot blowers. The smelt is discharged to the dissolving tank through the water cooled smelt spout and the spout is designed for automatic rodding by Metso's DeckHand, an industrial type robot.
Metso is a global supplier of sustainable technology and services for mining, construction, power generation, automation, recycling and the pulp and paper industries. We have about 28,500 employees in more than 50 countries. www.metso.com
