Title
(EN) METHOD FOR CONVERTING PALM OIL MILL LIQUID EFFLUENT TO A SOLID BIOMASS TO FACILITATE RECYCLING
(FR) PROCÉDÉ DE CONVERSION D'UN EFFLUENT LIQUIDE DE MOULIN À HUILE DE PALME EN UNE BIOMASSE SOLIDE POUR FACILITER LE RECYCLAGE
Abstract
(EN)
A method is disclosed for treating liquid effluent (200) discharged from the palm oil milling process by converting it to a solid biomass (214) with significantly reduced moisture content to make it suitable for recycling either as a biofuel or as a biofertilizer. The liquid effluent (200) may initially be pre-treated using a mechanical separation means to reduce its suspended solids content and/or treated using a steam stripping means to reduce its volatile matter content. Its moisture is then significantly reduced using an evaporating means (207). The concentrated sludge (209) discharged from the evaporating means (207) is mixed with one or more bulking materials (211) frorn the palm oil milling process to increase its porosity. The mixed biomass is then dried (213) using a drying means to produce the solid biomass (214). Drying may be achieved using an external heat source or by biodrying. Drying using external heat source is achieved using a convection dryer such as a rotary dryer or conveyor dryer. Biodrying makes use of the heat generated during the initial stages of composting using either the windrowing technique or in-vessel biodrying technique. The condensate (208) containing the evaporated components discharged from the evaporating means (207) is either treated and recycled back to the palm oil mill or treated and discharged.

L'invention concerne un procédé de traitement d'un effluent liquide (200) évacué du processus d'extraction d'huile de palme par conversion de ce dernier en une biomasse solide (214) ayant une teneur en humidité considérablement réduite pour le rendre approprié au recyclage soit en tant que biocarburant, soit en tant que biofertilisant. L'effluent liquide (200) peut être initialement prétraité à l'aide d'un moyen de séparation mécanique pour réduire sa teneur en solides en suspension et/ou traité à l'aide d'un moyen de distillation par entraînement à la vapeur pour réduire sa teneur en matières volatiles. Son humidité est ensuite considérablement réduite à l'aide d'un moyen d'évaporation (207). La boue concentrée (209) évacuée du moyen d'évaporation (207) est mélangée avec un ou plusieurs matériaux de gonflement (211) provenant du processus d'extraction d'huile de palme pour augmenter sa porosité. La biomasse mélangée est ensuite séchée (213) à l'aide d'un moyen de séchage pour produire la biomasse solide (214). Le séchage peut être réalisé à l'aide d'une source de chaleur externe ou par bioséchage. Le séchage à l'aide d'une source de chaleur externe est réalisé à l'aide d'un séchoir à convection tel qu'un séchoir rotatif ou un séchoir à convoyeur. Le bioséchage utilise la chaleur générée pendant les étapes initiales de compostage à l’aide soit de la technique d'andainage, soit de la technique de bioséchage en cuve. Le condensat (208) contenant les constituants évaporés évacués du moyen d'évaporation (207) est soit traité et recyclé vers le moulin à huile de palme, soit traité et évacué.
