Energy recovery
Heat recovery from condensation is a process that allows for the reuse of heat carried by moist flue gases resulting from the combustion of coal, waste, or biomass in industrial facilities. This process is particularly applicable in power plants, heating plants, cement plants, paper mills, incinerators, and in all other industrial sectors where heat is otherwise lost irreversibly. The recovery technology involves the contact of hot flue gases with cooling water in condensing scrubbers, resulting in the cooling of the gases and the condensation of moisture contained in the flue gases. The condensation process is highly energy-intensive, significantly increasing the overall thermal efficiency of the installations.
The heat of condensation is transferred through heat exchangers to a recipient, such as a district heating network, and the condensate obtained in the condensation process is purified. The purified condensate is characterized by high purity and can be used in other processes, serving as a substitute for other water sources, such as tap water.
Due to changing regulations and progressing global warming, which is further limiting our already scarce water resources, industrial plants as well as water supply companies are being forced to optimize their water management. One of the key elements of this trend is water recovery. The essence of this process is the return and reuse of water treated to the required standards.
Every plant produces wastewater with varying levels of contamination, but in most cases, regardless of the degree of contamination, it is possible to successfully recover water from it for reuse within the plant.
For preliminary treatment (removal of solid particles) necessary for water recovery, we use settlers, filters, or ultrafiltration. For further treatment, such as the removal of dissolved compounds, we employ reverse osmosis. In the case of complete wastewater elimination, evaporators can be used (ZLD technology), where, in addition to recovered water, we obtain salt that can be further utilized or disposed of. For the recovery of rinse waters, lamellar separators, membrane technologies, pressure ultrafiltration, and vacuum ultrafiltration are applied. For wastewater from other production processes, where oily substances, oil derivatives, and other difficult-to-remove compounds may be present, an individual approach is required when selecting the appropriate technology.
Water recovery is undoubtedly a costly investment, but from a global perspective, it is profitable, as the costs of extracting from already limited resources are significantly higher. Our company is proud to have implemented such systems for dairy processing plants, where membrane technologies are utilized.
Due to the increasing amount of sludge/waste or their hazardous nature, which makes storage impossible, thermal treatment methods for sludge/waste are gaining importance. Thermal treatment involves, among other things, burning sludge/waste in specially designed furnaces. Depending on the type and quantity of waste, different furnace designs are used. Very often, the combustion systems are equipped with heat recovery installations to improve the energy balance of the installation.
The data obtained from the client regarding the quantity and parameters of the produced sludge/waste is analyzed by our team of technologists, who choose the optimal method for their thermal treatment. We work with clients from concept, through design, implementation to commissioning.
Thermal methods of waste conversion are constantly being developed and adapted to the current energy market situation. In light of rising energy prices, methods of recovering energy from waste are gaining importance. One of the methods is the RDF waste gasification process, which aims to dispose of waste through gasification, produce and purify syngas, and burn syngas in cogeneration engines to generate electricity and heat.
Our technologists collaborate with companies offering gasification technologies and, in cooperation with global reactor manufacturers, are able to develop complete RDF gasification plants - from concept to implementation.
Our priority is to create projects that meet the highest requirements and standards, so we pay attention to every detail at every stage of our work. We utilize innovative solutions to ensure that our creations are characterized by functionality, efficiency, and reliability.
