Description: Das Projekt "Verwertung von grossvolumigen Quecksilberhaltigen Rektifikatoren ohne jede Umweltbelastung" wird vom Umweltbundesamt gefördert und von GMR - Gesellschaft für Metallrecycling mbH durchgeführt. There is an increasing interest within the region of EU in exploitation of voluminous mercury-containing rectifiers without any environmental pollution. The problem of exploitation of such rectifiers is not solved until now. The recommended project allows the complete recycling of the rectifiers without any environmental damages on easy terms. The exploitation of voluminous mercury-containing rectifiers (diameter greater than 1 m, height greater than 1,5 m) without any environmental damages is only possible by the use of thermal processes under reduced pressure. Using the recommended technology for small rectifiers for the voluminous ones would lead to expensive distillers with the need of high energy - but without any guarantee of mercury free material after treatment because of the bad heat transfer and the problems with the sealings. Therefore it is recommended in the project to use the vacuum vessels of the rectifiers as distillers themselves in combination with special heating elements. The condensation of the evaporated mercury takes place in special low-temperature condensors, the waste air is purified by active coal. The recovered mercury is purified to high quality and sold. The refined mercury free metals were used in the metallurgy. The permission procedure and the erection of the equipment takes place in 1994/95. The start of the treatment will be at the end of 1995 or at the beginning of 1996. The calculated amount of nearly 500 rectifiers should be treated within 5 years. It is recommended to support the project by suitable steps of the legislator to be sure to avoid any risk for the environment.
