Tratamiento POME
El tratamiento sostenible de efluentes de molinos de aceite de palma (POME) nunca ha sido más difícil. Los métodos de tratamiento tradicionales imponen exigencias a los molineros, especialmente frente a estrictas normativas medioambientales. Basándose en nuestro conocimiento de las tecnologías de evaporación y separación, Alfa Laval ha desarrollado enfoques únicos para resolver los desafíos actuales y futuros de POME. Descubra una gama de soluciones para cumplir de forma rentable con los requisitos locales y aumentar su rentabilidad en el proceso.
Alfa Laval POMEVap: palm oil effluent treatment to eliminate ponding
- Sustainable POME treatment without traditional ponding, meeting relevant environmental standards
- Flexible solutions that can be easily incorporated into new mill designs or retrofitted in existing installations
- New business opportunities to convert palm oil mill effluent solids into animal feed or fertilizer for new sources of revenue
- Possibilities to recover a portion of the palm oil in the POME and thereby increase the profitability of your mill
- Innovation based on Alfa Laval’s proven, reliable thermal and separation technologies used for decades in a huge range of industries
La composición del POME incluye agua, aceite y sólidos en suspensión. Ácido y rico en contenido orgánico, el POME contamina los cursos de agua y produce gases de efecto invernadero cuando se utiliza un sistema de estanqueidad. Alfa Laval ha adoptado un nuevo enfoque radical para este reto con POMEVap y POMEVapPlus. A diferencia de los sistemas de estanqueidad convencionales, estas soluciones que ahorran espacio permiten un tratamiento sostenible del POME. Utilizando tecnologías probadas de Alfa Laval, separan el POME en agua limpia y flujos de lodo sólido. Los lodos pueden procesarse para crear valiosos subproductos. El agua limpia separada puede ser tratada o vertida. Alfa Laval también puede ofrecer una solución de vertido cero de líquidos para reciclar el agua clara separada, ayudando a las fábricas a cumplir con los requisitos medioambientales más estrictos.
A one-of-a-kind solution to POME treatment
Alfa Laval POMEVap and POMEVapPlus are innovative solutions unlike anything else on the market today. Compare the different solutions with conventional ponding techniques to discover how our technologies can create new opportunities for more profitable POME management in your mill.
Conventional palm oil mill effluent ponding systems
For POME treatment, palm oil mills have traditionally relied on ponding systems that take up a huge amount of space and involve both anaerobic and aerobic biological processes. The anaerobic process generates methane (greenhouse gas), emitting it into the surrounding atmosphere. This has led some governments to mandate the costly addition of a methane capture facility. Further, the treated effluent from ponding may not meet stringent biological oxygen demand (BOD) limits or discharge colour requirements.
Alfa Laval POMEVap
POMEVap is based on Alfa Laval’s well-established AlfaFlash forced circulation plate evaporator technology. In contrast to ponding systems, POMEVap is a compact installation that minimizes space concerns. The evaporator separates the POME into solids and a clear liquid stream, thereby eliminating generation of methane to the atmosphere and minimizing BOD in separated water. Separated clear water can be discharged outside the mill or further treated to meet effluent discharge standards of local regulations. Through processing, the solids can be used to produce new sources of revenue such as animal feed or fertilizer.
Alfa Laval POMEVap for POME treatment
In addition to all the benefits of the standard POMEVap, POMEVapPlus offers new possibilities to recover more palm oil by combining AlfaFlash evaporation technology with the Alfa Laval PANX decanter. The evaporation step significantly increases the concentration of oil in POME, enabling maximum recovery of oil through the use of the decanter. Along with the by-products generated by the POME solids, the increase in oil yield can create a new revenue stream for your mill.
Improved efficiency for POME treatment ponding systems
With a comprehensive range of palm oil solutions, Alfa Laval can also support mills with existing ponding systems to help you optimize the operation of your current set-up. The Alfa Laval ALDEC decanter, for example, is a proven, cost-effective and reliable solution for removal and dewatering of digested solids from anaerobic and aerobic ponds.
POME treatment - explore the Alfa Laval POMEVapPlus
A. POME
The dilute raw POME is fed to the POMEVapPlus system. The typical composition of raw POME is 5% NOS (Non-Oil Solids), 1% oil and 94% water.
B. AlfaFlash plate evaporator
The AlfaFlash plate evaporator is specially designed to handle challenging and fouling liquids like POME. Alfa Laval’s unique corrugated plates and carefully designed recirculation flow rates creates high turbulence (shear rate) within the plates resulting in a significant lower fouling rate, efficient heat transfer, and higher up-time. The AlfaFlash plate evaporator splits the POME into water vapour and solid concentrate.
C. Cyclonic separator
A high-efficiency cyclonic separation vessel separates the mixture of water vapours from solid concentrate. The water vapour is separated at the top outlet and the solid concentrate is collected at the bottom outlet.
D. Separated water vapours
The separated water vapours at the top outlet of cyclonic separator are condensed to get the process condensate which is clean and can be re-used after further treatment.
E. Recirculation pump
The recirculation pump provides a high flow rate to ensure turbulent flow of the liquid inside the heat exchanger, which keeps solids moving in suspension.
F. PANX
The Alfa Laval PANX-series of decanter centrifuges decanter assists to achieve maximum separation oil recovery from solid concentrate with lower energy requirement.
POMEVap: How it works
The POMEVap system can be designed using a thermal heat source such as motive steam from turbine exhaust or using electricity, with number of effects depending on the capacity requirements and amount of steam/power available on site. Watch this video to learn more.
