Abstract


Coalescing Clarifier for Crude Palm Oil Clarification

When oil passes through interspaces between the coalescence plate separator plate, it imparts shear forces to the small oil particles causing them to agglomerate, thereby preventing the formation of emulsion. As a result, the diameter of the oil particles become large and separation efficiency improves.

Abstract


Achieving a BOD below 20 mg litre-1 for POME: is it a myth or a reality?

There are a number of effluent treatment systems available now in the market claiming to give excellent results. This could be a valid claim because in most cases it would have performed satisfactorily with other types of effluents. But the problem often overlooked is the dissimilar characteristics of different types of effluents. Each treatment system has to be separately evolved and custom made to be effective. It could be a costly mistake if we blindly adopt a system with a proven track record of effluent treatment when dealing with another industry. One of the critical characteristics of palm oil mill effluent is its extraordinarily high biochemical oxygen demand (BOD), that can be as high as 30 000 mg litre-1. Currently, most mills are struggling to keep it below the existing Department of Environment (DOE) limit of 100 mg litres-1. Soon this will have to be lowered to 20 mg litres-1 to keep pace with the rest of the world. Recently, a new method called the biological chemical mechanical and membrane (BCMM) technology has been tried out under R&D in MPOB Palm Oil Mill Technology Centre (August 2010 – February 2011) and in FELDA's Kilang Sawit Neram (January – August 2012), that seemed to deliver consistent results under the normal mill operating conditions.

Abstract


The present status and potentials of biogas production and utilisation for palm oil mills-based residues

The rapid growth of biogas plants in Malaysian palm oil mills in recent times can be attributed to the keen interest of the industry to reduce the greenhouse gas (GHG) emissions from palm oil production, coupled with the potential benefits which can be realised by capturing and utilising the large quantities of biogas to produce renewable energy. During the initial development in the last five to six years, we have observed the applications of the various anaerobic digester technologies for biogas recovery mainly from palm oil mill effluent (POME) treatment systems, where to date, close to 10% of the palm oil mills have installed some forms of biogas-capture systems. Exponential growth is expected with this trend extending to cover all of the approximately 1000 mills in the ASEAN region. With the expansion of the biogas industry, the potential of the next generation biogas production using alternate sources can be expected. Palm oil mill residues, like POME slurry, solid palm waste materials (empty fruit bunches and oil palm by-products can become alternative or supplementary feedstock materials, to give much higher biogas yields than that from POME. Accompanying this development, various methods of utilisation of the biogas generated has been realised, but it was limited mainly to on-site applications in accordance with site specific factors. These include applications for thermal energy recovery in the different types of boiler systems and for power generation via gas engines for on-site use or connection to the grid. However, the challenges still remained for development of off-site utilisation for the biogas recovered. Prospective applications after upgrading of the biogas (biogas refining), such as compressed natural gas (CNG) equivalent (transport fuel), feeding to natural gas (NG) pipeline and bottling, and transportation for offsite industrial use, also can be foreseen.

Abstract


Innovation potentials in palm oil mill design

Horizontal sterilisers are in dire need for improvement. There is great potential for university students to explore the field of sterilisation. It has been found that the sterilisation process practiced by the industry is not founded on sound process technology. There is ample room therefore for improvement not only in the field of sterilisation, but in many other areas of processing as well. In this article, we would focus on sterilisation, the least understood process operation.

Abstract


Improving mill oil extraction rate under the Malaysian National Key Economic Area

Increasing oil extraction rate (OER) to 23% by 2020 is the aim of the fourth Entry Point Project (EPP) under the palm oil National Key Economic Area (NKEA). The national OER over the years have not made significant improvements due to the inconsistent quality of fresh fruit bunches (FFB) supplied to the mills coupled with inefficient machinery installed in some old mills that had expanded but not their machinery resulting in high oil losses during operation. Several strategies were designed to ensure that the objective of NKEA is achievable. Now close monitoring of FFB quality is being implemented by adopting one mill one enforcement officer policy. As for the oil loss, strict protocol on managing oil loss at mill should be the basis for gauging oil loss. The strategies put forward by the NKEA Laboratory is a testimony to a joint understanding between the policy-maker (government) and the industry.

Removal of abrasive materials from FFB before milling

Abstract


Removal of abrasive materials from FFB before milling

Fresh fruit bunches (FFB) delivered to mills in Malaysia contain a high volume of trash that accompany the loose fruits when scooping loose fruits from the field using hand or tractor shovels. In the early days of the industry when loose fruits were handpicked, the problem of FFB contamination by trash was virtually non-existent. The acute labour shortage coupled with high labour cost has generated the present problem of high trash content in FFB. The sand, the main component of trash causes serious erosion on process machinery. In addition, the wasted iron is also picked up by the palm oil, which in turn become contaminated by the iron it picks up resulting in oxidation of the palm oil. In order to address this serious problem, many methods were tried out by the industry but none offered a satisfactory solution. This article presents a simple and effective method of selective elimination of trash in FFB based on 12 trials conducted in a mill in August and September 2011. The volume of sand and stones removed was observed to exceed those observed in the conventional system. The implication of the study reveals that further system extension and development can bring about even better trash removal efficiency.

Palm biomass fuel utilisation in palm oil mills

Abstract


Palm biomass fuel utilisation in palm oil mills

Since the beginning of the industry, Malaysian palm oil mills have been utilising part of the palm biomass as an energy source for mill operation. The main constituent of the biomass used for power generation in the mill comprised part of the mesocarp fibre and most of the dry palm kernel shell called the fuel mix, at a ratio of about 60% to 40%. The entire empty fruit bunches, the remaining mesocarp fibre and most of the palm kernel shell - mainly the wet palm kernel shell were disposed of or incinerated. The objectives of this study are to compare the CO2 emission during biomass fuel combustion with diesoline combustion. The equivalent mass of diesoline was estimated using its calorific values as a basis for computing the enthalpy content of the respective fuels. Analytical results confirmed that the greenhouse gases emission (GHG) from the combustion of the ‘biomass mixture’ in a boiler is about 2.7 times that of the GHG emission from diesel combustion, when producing the same amount of electrical energy. Although green energy has its merits in helping us to preserve the fossil fuels for the use of future generations its use for power generation as a substitute for fossil comes with a price, viz: the additional GHG released to the atmosphere compared to fossil fuels. The mills use about 15% of the total fibre and 22% of the total shell produced to generate sufficient energy for processing fresh fruit bunches. The fast depleting fossil fuel reserves of the world and the environmentalist’s concern for clean energy has now brought the global attention to the surplus biomass in the mill. This has also encouraged the government to implement suitable policies to promote renewable energy generation in Malaysia.
