Poppi’s patented slurry heating system was recently started up in the Facemag plant in Morocco with very satisfactory results. Before being sent to the atomizer, the slurry is heated in a controlled way by making it pass through two heat exchangers fitted in series. The rising temperature obtained is around 25 ° C (from the initial 40 ° C, it heats up to 65 ° C), and this heating saves 40Nm³ / h of methane without altering the technical features of the product
