Oil Purification Systems Australia

Our client experienced a significant water and debris contamination event in the Fixed Bearing circuit of the SAG Mill. The mill was immediately shut downto avoid bearing damage and the contaminated oil was removed and new then oil introduced. Even so, there was concern that the circuits still had potentially harmful debris and moisture present.  For More Update, Visit Us http://www.biokem.com.au/

Moisture could be your No. 1 Lube Oil Problem

Compressors handling ‘sour’ natural gas with higher levels of Hydrogen sulphide can strike real problems if the oil interacts with the product gas and any moisture is present. The result is an attack on the compressor alloys called sulphide stress cracking, a form of hydrogen embrittlement. In extreme cases this can cause a compressor casing to split.

Additives are designed to be a sacrificial product. They are consumed as the additive pack anti-oxidant neutralises unwanted chemical contaminants. However, if additives such as demulsifiers (which help shed water) are exposed to large amounts of water contamination, the demulsifiers can be stripped from the oil very quickly leaving the oil at risk.

Other additives like Extreme Pressure (EP) and Anti-wear (AW) can be hydrolyzed (broken down into acids) by water and deny your Equipment the protection those additives are designed for. If left unchecked the by-product is sludge and varnish.

A trial of machines by the BHRA compared equipment life to moisture contamination. They found the correlation between dry oil and oil with high moisture content. Oil with a moisture level of 5,000 ppm was dehydrated and trialled to measure equipment life. The results show that equipment with oil drier than 100ppm has three times the life of a machine with oil of 450ppm moisture.

The Hidden Dangers of Topping Up Your Lube Oil

Synthetic lubricants were born out of a need for better lubricating properties, and the unavailability of crude oil in Germany. Aviation was the first application for synthetic lubricants, as they are superior to mineral oils at cold start up and cold climates. Synthetic oils have a higher Viscosity Index, offering better viscosity stability at varying temperatures. Group IV synthetic oils are man-made from PAO’s (polyalphaolefins) and Group V oils are made up of polyesters, phosphate esters, di-esters, alkylated benzenes and other synthetic molecules.

Another way of comparing the various refinement of oil is to compare the oil to a fluid with balls of varying sizes in suspension. The lower the Group level of oil, the greater variety of ball size and shapes (which represent the types of molecules). Group 1 oils will have millions of differing atomic compounds (molecules) making up the oil. As the oil is refined, the oil is more uniform and the ‘balls’ are the same size. Synthetic oils have only one size ball.
