Joint district heating project for a fossil-free future
Vattenfall has realised with the Hakfort project the largest capacity heat transfer station utilising plate heat exchangers . This investment of Vattenfall enables the expansion of the Amsterdam district heating grid . In total , the district heating grid will heat up to 290.000 households in Amsterdam by 2040 . An unprecedented capacity of 84MW uses SWEP B649 heat exchangers . In the early 1990s the city of Amsterdam set out on its decarbonising heat journey in a joint venture partnership with Vattenfall , one of the largest energy suppliers in the Netherlands . Since those early days , the Amsterdam district heating network has gone from strength to strength . To enable more and more households to be able to benefit from district heating , Vattenfall is expanding the heat network in Amsterdam-
Southeast , by laying extra pipelines and building a heat transfer station . The Hakfort Heat Transfer Station is integral to the project , as it will transfer heat from the main heat network based in Diemen to the new area of Amsterdam-Zuidoost , benefiting existing and new customers as more housing is developed . And it is here that SWEP has played a major role . SWEP ’ s first involvement was at the pre-tender stage in 2018 after Vattenfall had appointed Croonwolter & dros as lead contractor for the project . Vattenfall ’ s project team specified a requirement for brazed plate heat exchangers . SWEP ’ s proposal highlighted their gasket-free BPHEs which provide cost effectiveness and a compact footprint , along with their ability to maintain high level working with little wear of components , therefore requiring minimal maintenance . In addition the SWEP BPHEs are easy to install and are very energy efficient , with 95 % of the material used in the heat exchangers used for heat transfer .
Celebrations around the world to mark Alleima as a standalone company
Alleima , with headquarters in Sandviken , Sweden , is a global manufacturer of high value-added products in advanced stainless steels and special alloys , as well as solutions for industrial heating . On April 27 , 2022 , at the Annual General Meeting of Sandvik AB , Sandvik shareholders made the historic decision to distribute and list SMT on the Nasdaq Stockholm stock exchange . It was also decided that the new company name would be Alleima , a combination of the words “ alloy ” and ” material ”, two core strengths of the company ’ s business .

Guardian Glass commissions GEA gas cleaning plant
For one of the world ’ s largest flat glass manufacturers ( float glass ), Guardian Glass , the plant engineering and system supplier GEA developed and installed a high-performance gas cleaning plant at the Czestochowa site in Poland . GEA ’ s gas cleaning system included a dry DeSOx reactor , followed by an electrostatic precipitator for dust removal , a downstream DeNOx reactor and the associated components for storage , transport and dosing of reagent and precipitated dust . The new GEA gas cleaning plant was successfully completed and commissioned in early 2022 . The production line has a capacity of 1,000 tons per day . The new GEA gas cleaning plant reduces emissions for dust , SOx and NOx by up to 90 percent . This is an extremely significant reduction in the environmentally harmful emissions that occur during energy-intensive glass production . In this way , the GEA solution makes a significant contribution to meeting the customer ’ s legal requirements and sustainability targets . Dust and reaction products separated in the electrostatic precipitator allow direct reuse as raw material for glass production . GEA thus directly helps the customer reduce the amount of raw material required per ton of glass produced . Despite the impact of the global corona pandemic , GEA was able to meet the project schedule in a joint effort with the customer . Special attention was paid to safe plant operation even at high gas temperatures . In this case , water is injected directly into the DeSOx reactor to cool the raw gas . Another safety feature is the active plant bypass by means of a second blower .
