USE OF MODELS

OBJECTIVES: LQARS CEMAGREF TRATOLIXO Procedure for data collection Data collection Optimize BTPs under study Simulate new scenarios DatabaseModels Simulator

LQARS CEMAGREF TRATOLIXO USE OF MODELS 1. Waste management systems without a BTP - Help on the decision on whether or not to include a new BTP in the system - Presentation of solution(s) in terms of: -technical aspects (equipments configuration) -costs -maybe a range for product characteristics and plant performance

LQARS CEMAGREF TRATOLIXO USE OF MODELS (cont) 2. Waste management systems with a BTP A. Solution(s) for the inclusion of new equipment -technical aspects (equipments configuration) -costs -maybe a range for product characteristics and plant performance B. Solution(s) for the improvement of the plant without changing equipment configuration -New operating conditions -Prediction of volatile solids degradation
