Wear control specialist Filter Focus will be displaying its Vacuum Dehydrator system at the 86th annual South African Sugar Technologists’ Association (SASTA) Conference, which is being hosted in Durban from August 6 to August 8, 2013.
Filter Focus points out that the company's Vacuum Dehydrator can greatly assist the local sugar industry in combating the effects of emulsified, free and dissolved water in oil. "Water contamination is present in almost every sugar processing plant, and the numerous problems associated with this kind of contamination are vast."
Filter Focus explains that the Vacuum Dehydrator, which was developed in-house by Filter Focus in 2010, has the ability to rapidly remove all water, gases and acids from oil. "Wet or emulsified oil is drawn into the system under vacuum. This provides the ideal environment to quickly and effectively evaporate dissolved water and gases."
According to the company, all vapours and gases enter a condensation unit and are released into the water receiver - where cleaner and drier oil is then passed back to the oil tank. "Dependent on the volume of water contamination, multiple passes will be required to achieve target dehydration levels."
Filter Focus indicates that water contamination in systems promotes oxidation, and can lead to failures in components such as bearings and shaft journals, as well as the jamming of mechanisms such as pilot valves, trip cylinders and hydraulic pistons. "Additives are contained in oil to improve lubricating properties. These additives can, however, be washed out or removed by water contamination, chemically altering and leaving the oil underperforming,” they add.
In numerous tests run by Filter Focus on the Vacuum Dehydrator, results have been impressive to date. The company points out that during an in-house test whereby a standalone tank of lubricating gear oil was purposely contaminated with water, independent oil analysis showed that the initial state of the oil had 4,7 percent (47 000 ppm) water content.
A second sample was taken after eight hours of Vacuum Dehydration and showed an improvement in water contamination to only 124 ppm. After placing a Filter Focus proprietary filtration system to the outlet of the Vacuum Dehydrator, results showed an improvement with a further reduction to 39 ppm water content, which is regarded as negligible, as this is drier than unused bulk oil supplies.
Filter Focus believes that the 2013 SASTA Conference, which is being hosted at the Durban International Convention Centre, serves as the ideal event for Filter Focus to showcase the benefits of the Vacuum Dehydrator. "The SASTA conference brings together influential decision makers and experts who have a direct involvement in the technical aspects of the South African sugar industry. By exhibiting the company's capabilities to all these guests in one location, I believe that Filter Focus has the potential to gain measurable market share in the local sugar industry," they conclude.
