Up-Scaling Methodology provide knowledge for a process book. Application to a cementation process

Abstract : This paper describes an up-scaling methodology applied to a cementation process. The final goal is to produce a formal document which describes the process and the associated technology by using the expected product characteristics. First of all, the size of the mock-up test platform and the volume of the end-product are taken into consideration. Either the demonstration can be carried out on a full-scale drum or modeling must be prepared to consolidate the specifications sought. Examples are given in the paper. The test methodology is described and includes six pilot trials. In the first phase the volume of the product is gradually increased and technology adjustment must be necessary. Therefore the nominal and the sensitivity tests enable the determination of the operating parameters, guaranteeing that the mortar produced has the same properties as that obtained in laboratory. The transient and degraded tests enable definition of the operating parameters and the procedure to maintain plant safety, to protect the process equipment and the material. Finally, the main objective of the extended long-term testing is to demonstrate that the operating parameters remain operational over a full production campaign.This qualification program for the cementation of sludge from decontamination effluents enabled an approval request file for a new mortar package production using the cementation process to be prepared.
