Better diesel for powerful engines – Diesel is the most important fuel for engines not only in industry but also in agriculture. But diesel is not always diesel. Especially in the tough conditions encountered in agriculture and industry, diesel is frequently contaminated with condensation water and dirt particles mainly during transportation and storage.

This problem is particularly serious in large farming operations where tractors and machinery are increasingly being used. What is the point of specifying the degree of purity of the diesel in the manual as an obligation under warranty when only low-grade diesel qualities are available locally?

The manufacturers of vehicles and engines are increasingly adopting the practice of incorporating disc separators in their offers to buyers in the agricultural sector. These machines are capable of dealing with this problem, even in extremely remote regions. The farms can therefore immediately feed the diesel oil from the tankers through a disc separator and store the purified diesel. Alternatively, the contaminated diesel could be intermediately stored and circulated through the separator later into a fresh tank.

The smallest disc separator operates at a capacity range around 1000 l/h. This amply covers the requirements of farming operations. And, since the separator is also available in a light, transportable mobile version, it can be flexibly used from farm to farm.

Huading Separator supplies practical, customized solutions not only for the agricultural sector but also for large petrol stations (for diesel locomotives and busses) and for mining.

Spent /waste oil is generally denoted as an oil which, due to changed properties, no longer meets the original requirements (e.g. oiliness), and whose characteristics cannot be further enhanced by treatment. Potential sources are spent oils from engines and gearboxes, oily emulsions, bilge water, tank residuals etc. These waste oils have different densities, viscosities and impurity levels.

Waste oils can be treated or refined by means of chemical-physical processes or used as high-grade fuels in the cement industry or in smelters. The waste oil ordinance stipulates the priority of the material treatment of waste oils by means of refining in as far as this does not conflict with technical and economic as well as organizational constraints. The composition of the waste oil as well as the level of contaminants in the waste oil likewise determine the method of disposal.

If the waste oil is to be incinerated, all impurities such as solids and water must be removed beforehand. During incineration, the water content lowers the calorific value. The solids lead to deposits in the boiler, clogging of the nozzles and diminish the thermal efficiency.

Waste oil can be treated by means of mechanical centrifugal technology. Decanters and self-cleaning separators can be used for separating solids and water from waste oil.
