Description: Das Projekt "Energiesparende Hochtemperatur-Waermepumpe" wird vom Umweltbundesamt gefördert und von York International GmbH durchgeführt. Objective: To test the use of a commercially available high-temperature heat pump from BBC-YORK in a crystallisation process. General Information: High-temperature heat-pumps can save substantial primary energy, but they still need to overcome a few hurdles before gaining wider acceptance. These are: - high investment cost - too little knowledge of properties of cooling media and lubricants, at high temperature - lack of proof of reliability - lack of experience with scaling or crust-forming media, such as in crystallisation. To answer these doubts, a demonstration project will be built in Ladenburg, Germany, in the chemical plant Benckiser-Knapsack GmbH. The current crystallisation process requires an input of 860 kg/hr of 110 deg C steam. After crystallisation, vapours of approx. 70 deg C and 0.32 bar are released. They are pumped, condensed and then let-off in the atmosphere. In the new system, a heat pump will provide the necessary heat input using the refrigerant R-114 as heat carrier (R-114 has a liquefaction temperature of 116 deg C). Sufficient 70 deg C saturated steam is available as heat source and the vaporisation temperature of R-114 is set at approximately 64 deg C. The condenser in the heat pump is operated electrically. The R-114 circuit works as follows: The refrigerant R-114 is pumped in gas form from the tubular evaporator by a piston-type condenser which compresses it. A regulator then decompresses the R-114 from the 116 deg C liquifying temperature to the 64 deg C vaporisation temperature. Solid particles which cannot be eliminated by the steam will gradually scale the piping system and this will require regular cleaning but as the plant cannot be stopped, a dual piping must be built so that the flow can simply be diverted into one system while the other is being cleaned.
