Abstract


Development of a pre-treatment plant for residues from the Malaysian Palm Oil Industry

In the overall chain for the palm oil production, large quantities of biomass by-products are generated, up to almost five times the oil production (on dry weight). Most of the materials are generated in Malaysia and Indonesia, accounting for 87% of world’s palm oil production. The use of these residues as by-products for materials, energy, green chemicals or biofuels offers perspectives for development of an economic and environmental sustainable food oil production chain that fits well in the development of a bio-based economy. This requires that any biomass extraction from oil palm plantations does not negatively affect the nutrient balance and soil organic matter content. The present work describes the development of a 5 t hr-1 pre-treatment plant (PTP) line-up for these materials to arrive at a standardised or commodity product that can easily be handled in road transport and intermediate storage. Results are included for the pre-treatment of (i) empty fruit bunch from the palm oil mill, (ii) both fresh and (iii) plantation dried oil palm fronds, and (iv) oil palm trunks from replanting. A full PTP suitable for processing of all materials includes a two-stage size reduction, belt dryer (suitable for using pre-heated air), and a cubing machine to produce compacted cubes. The technology selection and equipment sizing were fully supported by results of an extensive field test programme carried out in Malaysia with local biomass and with commercially available equipment. The developed PTP lineup is generic with few equipment for all biomass materials assessed (expect for the initial size reduction steps). As all required technologies are commercially available, the PTP can be installed commercially when a project opportunity arises.

Abstract


Heat transfer theory and heat pipe development for palm oil industry application

Heat could be transferred in three ways which are conduction, convection and radiation. The recent development to produce a faster heat transfer material was the heat pipe that combines the principles of both thermal conductivity and phase transition to efficiently manage the transfer of heat between two solid interfaces. The objective of this research work is to introduce the heat pipe phenomena using existing heat transfer theory and discuss the application in palm oil industry which may enable more biomass saving.

Abstract


Creating a business plan to generate knowledge-based income

The Malaysian palm oil industry is transforming into a knowledge-based industry. But does the industry fully exploit the results of its R&D efforts and protect its innovations via intellectual property rights. Technologies and innovations are easily adopted and copied. Therefore, there is an urgent need to create a business routine which, amongst others, includes the steps of identifying, protecting and managing the results of these R&D activities.

Abstract


Future milling concepts or idiosyncrasies? Part I

The contents of this article are intended to offer to the industry discussions of some imaginary mill design concepts that should not be taken too seriously as they are far from perfect. It may even be qualified to be termed idiosyncrasy but even then it will still serve the purpose of tickling the intelligence of our mill engineers who are no doubt quite innovative. This is only a simple offshoot from the mind of a palm oil mill engineer based on his years of experience in the industry reinforced by his research exposure in the Malaysian Palm Oil Board, a combination very few people will have the opportunity to be blessed with. When writing this article, I tried my best to totally remove all the knowledge I have on existing methods of milling operation to prevent my current thinking from being skewed towards it. Perhaps this exercise itself may merit the credentials of a research work. In order to simplify this exercise, the system boundary and mill compound fencing shall be the same so that activities outside the mill like plantation operation and effluent treatment may be excluded.

Risk and crisis management

Abstract


Risk and crisis management

Palm oil is a prime industry in Malaysia. In the year 2010, 17.56 million tonnes of crude palm oil were produced from 4.69 millions hectares of oil palm planted area in Malaysia. Export earnings of oil palm products were worth RM49.6 billion. Thus, risk and crisis management are vital to minimise the loss affecting society, community, environment, water and the organisation in the event of an unexpected catastrophe.

Mongana basics: part 23- study of fuel and valorization of the waste products

The Waste Product the Palm Oil Mill - The approximate percentage composition of bunches processed in palm oil mills is given in Table 1. The amount of waste products is therefore dependent upon the type of bunch. Moreover, the extraction process affects the amount of non-oily solids and fibre which can be recovered or used. In the wet process, two-thirds of the fibre is washed away in water; in the continuous pressing process, one-third of it finds its way into the crude oil. Finally, in the centrifugal extraction technique or by manual press method, only very little of the fibre are removed.

Milling laws

Abstract


Milling laws

During process operation there are many basic principles which should be adhered to in order to operate the mill efficiently. Do you know that a large volume of oil is lost in the sludge water simply because the oil filled cells were not ruptured to release oil? The oil extraction rate (OER) of the mill can be raised quite easily if only certain simple procedures are followed. They are now documented under the code of practice (CoP). They are given in Figure 1 in a consecutive order so that it is easy to comprehend the correct flow from upstream to downstream. There are seven of them. Millers have to depend only on one upstream activity, i.e. good estate practice.
