CO2 saving processes
Increasing economic efficiency and reducing the CO2-emissions with energy recovery units in your industrial process.
Energy saving is a key success factor when trying to achieve a reduction of the carbon footprint, it can be made by improving process efficiency to recover waste heat, not only from the production process, but also from the hot process gas that in many cases is simply released into the atmosphere, unutilized.
The saving of energy costs and the reduction of CO2 emissions by avoiding fossil fuels make an Energy Recovery Plant an investment that not only provides competitive advantages that positively impact the final product cost, but also helps preserve our environment for the future generations.
GEA offers WHR (Waste Heat Recovery) units alone or in combination with gas cleaning technologies as well, using heat exchanger systems suitable for waste gas conditions such as dust content.
These heat exchanger units have been used in diverse projects worldwide and have proven reliable and highly efficient.
Usually, the GEA energy recovery system consists of:
The heat recovered from the flue gas can be used for:
Waste heat can be recovered from the clinker cooler waste gas as well as the preheater waste gas. Different heat exchanger systems shall be used for the two waste gases, because of the difference in dust content.
The heat can be used for the operation of an ORC turbine for power generation or to generate hot thermal oil or water for other uses.
The use of the heat energy in the gas cleaning process in the SCR is possible as well:
Depending on the available gas temperature upsteam and downstream the gas cleaning, the waste heat can be recovered at two different stages of the cycle.
Au cours des dernières années, les prix élevés de l'énergie et la nécessité de réduire les émissions de CO<sub>2</sub> ont renforcé l'importance des applications de récupération d'énergie pour tous les processus industriels. Le passage de gaz de procédé chauds dans la cheminée d'une usine implique une perte d'énergie thermique précieuse qui pourr...
L’industrie de procédé à procédés à forte intensité énergétique génère de grandes quantités d’émissions de déchets, qui restent souvent inexploitées. Il serait cependant avisé d’en exploiter l’énergie thermique, à la fois économiquement et écologiquement parlant, au vu de la hausse constante des coûts de l’énergie, du besoin des entreprises de re...
Industries across the board are working hard to meet net-zero targets while navigating stringent decarbonization regulations and legislation. At the same time, companies must balance growing demands for quality, product development...
Le café, le cacao, le lait, la viande, le poisson, les œufs : ces denrées de base reposent fortement sur l’agriculture intensive. Avec l’avènement des technologies à l’origine des nouveaux aliments, nous disposons de solutions...
L’histoire des centrifugeuses GEA a commencé en 1893, quand Franz Ramesohl et Franz Schmidt se sont lancés dans la fabrication de leur séparateur de lait mécanique breveté, qui allait paver la voie à la transformation laitière...
