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.

Abstract


Daring concepts: part 2 - alternative methods of CPO clarification

We must always ask the question: can the existing methods of oil extraction continue to remain stagnant say in 100 years’ time. If the answer is no, then this article will help to rejuvenate the mind to be pro-active and creative. This may sound ridiculous now but may improve the processing techniques currently being practiced in palm oil mills. We are all well-versed with the conventional system of crude palm oil(CPO) clarification comprising the desander, crude oil tank, crude oil pump, continuous static clarification tank, pure oil tank and the vacuum dryer. It is highly unlikely that in the year say 2112, 100 years from now, this method will still prevail without undergoing drastic changes in technology. Now to make an attempt to give an answer to the million ringgit question: what changes need some real dreaming and thinking? We hoped that millers will come up with some ideas but so far the response had been poor. No one is willing to think. Some are afraid of proposing fearing they may get ridiculed. This should not be the case as even intellectuals are known to have experimented with ideas which were fatuous and foolhardy. The following article is certainly not the expected next century technology. It is still within our present era. Crude oil separation can be split into a few phases.

Abstract


Introduction of the theory of corrosion to millers

Rust is a common electrochemical corrosion problem regularly faced by the palm oil industry but most millers and refiners have shown only lukewarm interest in taking serious steps to control rust in the mill machinery especially the storage tanks. Metals act as catalysts in the oxidation reaction where palm free fatty acids react with the iron from the bare metal surfaces to produce oil soluble metallic soaps that will eventually result in pitting on the inner tank surfaces. This in turn leads in oil quality deterioration in a relatively short period of time. The most common and effective way to prevent corrosion is to isolate the metal surfaces from electrolyte by keeping the surface dry and by applying a protective film coating like epoxy coating, epoxy phenolic coating or linseed oil. Proprietary rust treatment formulae may provide appropriate solution but tend to be rather expensive due to the fact that such formulations often comprise inexpensive common chemicals. Commercial rust converters usually are waterbased primer which contain tannic acid or phosphoric acid and an organic polymer usually 2-butoxyethanol that can be applied directly to a rusty surface without bringing the surface down to bare metal. The use is not practical because the accurate thickness and composition of the rust film is impossible to determine. Generally, increased corrosion resistance can only be obtained at an increased cost.

Daring milling concepts - part 1: measurement of oil in press liquor

This measurement has far reaching consequences if applied in the right places. With the advent of near infra red (NIR) analyser a whole world of opportunities are available to the industry which was not possible before. The NIR analyser has the capability to analyse about 100 analyses per minute and with the possibility of inter-phasing with computer the applications are limitless. MPOB has already successfully tested the analyser for accurate measurement of oil in crude and incorporated it in an automatic dilution control system with feedback loop to operate a pneumatically operated water injection valve. The capability of rapid analysis of the NIR analyser make it ideal for use in control systems with feedback control loop and servomechanisms. The performance of the system based on the graphical output of the percentage of oil in crude using computer interface appears to be quite satisfactory. This system may also be used in many applications where segregation of products with similar properties can be performed automatically.

A revolutionary concept in plantation management

Abstract


A revolutionary concept in plantation management

There is a drastic weakness in our plantation management system, including mill management as well. It is about time for the plantation management team to review the system in vogue for the past six decades or so. The existing system was suitable when Malaysian plantation industry started from coconut and moved on to rubber. At that time, engineers were non-existent in the plantation industry. The estate manager managed to operate the water pumps or generator using his engine driver who acted as his engineer for the minor engineering activities prevailing in the estates. The engineers came into the scene after the transition to oil palm as the mills needed engineers to operate the plants mainly due to the need for steam engineers to operate boilers. As the planters were mainly British, they had some fundamental knowledge about boilers as during the early days the ships plying between Britain and Malaya had steam boilers and turbines which later gave way to diesel engines. British boilers were world famous during those days.

Cheese and cheese analogues

Abstract


Cheese and cheese analogues

Milk consists about 87% water and 13% total solids of which 4% is fat, 3.4% protein, 4.8% lactose and 0.8% minerals such as calcium, magnesium, etc. Milk and milk products have been consumed as food since prehistoric days. Cheese-making was discovered accidentally in Iraq where it was initially developed. The cheese yield via acidification of lactic acid produced by bacteria during milk fermentation or rennet coagulation or combination of both is about 11% to 15%. Cheese varieties are classified by their hardness which varies according to their moisture contents. The increasing price trend of dairy cheese is now encouraging the manufacture of cheese analogues as an effective alternative for the culinary industry. The principal fatty acids found in milk triglycerides suggest that palm oil could be used as a butterfat substitute in cheese analogue formulation.
