Product Recevery for Spray Dryers

Project Details

Description

In most drying technologies either product recevery or gas cleaning are important unit operations. The dry product is suspended in the drying gas, and the particles have to be separated from the gas before further processing.This may be done by cyclones or filters or a combination thereof. The present project focuses on the filtration step. The aim of the project is to be able to perform accurate design of the filter system and required filter area for a given powder. The project consists of the following parts:
1) Development of laboratory methods to measure and predict the pressure loss over a filter cake as a function of velocity, temperature, humidity, powder load etc.
2) Compare the laboratory results with results from full scale
2) Perform calculations by the use of Computational Fluid Dynamics (CFD)of the gas and particle flow within industrial size filter housing including the deposition of particles on the filter bags.
