SILICONE OIL RECYCLING UNIT CMM-1.0

We are all used to associating power transformers with transformer oil. But in the modern world, electrical companies widely utilize silicone oil as an alternative to mineral based fluids. This is not surprising, considering silicone oil benefits and advantages:

Silicone Fluid (or Polydimethylsiloxane silicone oil) features:

 higher dielectric strength and temperature stability, low toxicity, low vapor pressure, low viscosity change  higher resistance to oxidation and chemical inertness

The above make silicone transformer fluid much safer...

Zimbabwe. Annual presentations of GlobeCore equipment

June 8, this year a number of presentations on GlobeCore equipment was held in Bulawayo (Zimbabwe).

It was only last year in August that similar presentations were held in the capital of Zimbabwe- Harare. Then, not all the representatives from Zimbabwe electrical industry could be present at the presentations. This called for a new opportunity for more participants to attend.

Traditionally, GlobeCore presented its equipment...

Refrigeration Compressor Oil

Compressor oil. Oil in refrigeration compressors is in constant contact with the coolant. This factor and the operation in various environment sets specific requirements for the oil. The oil for refrigeration compressors is made from naphtha oil and synthetic oil with low pour point and high chemical stability.

The chemical stability of compressor oil is its inability to react with coolants that are based on fatty halogenated...


Purification, clarification and regeneration of mineral oils and diesel fuel by the UVR-450/16 unit

Mineral oils. Industrial oil, turbine oil, transformer oil and compressor oils are used in difficult conditions of high temperatures, exposure to air, mechanical contamination, contamination with water etc. Over time, these oils lose their performance properties and need to be replaced or regenerated.

As for other petroleum products, for example, diesel fuel may lose its properties in long storage storage under exposure to sunlight, moisture, air and...


What to do with waste oil?

How to dispose of waste oil? If you are looking for an answer to this question, then you have a stock of oil larger than just one liter, formed as a result of operation of power transformers, rolling mills, turbines and other industrial equipment.

In fact, the problem of disposal of waste oil is not new, and it is not losing its relevance. The fact is that...


Selective Refining of Oil Fractions

It is known that crude oil cannot be used as fuel. It must be processed before a marketable product is obtained, one of the stages of such processing is selective refining.

The general meaning of selective refining is the processing of crude oil or derivatives to improve the quality of oil fractions. Practically, this is done by selective interaction of solvents on the components of “black gold”....


Oil Cracking Is...

Cracking is a widely used chemical method of processing crude oil. The process emerged as a consequence of increased gasoline demand and increased the yield of gasoline fractions of oil to 50-60%. Cracking can be applied not only to crude oil, but also to its distillate fractions.

There are thermal and catalytic cracking processes. In the former case, the process occurs at high temperature, in the latter...


Desulfurization of diesel fuel

Desulfurization of diesel fuel. Thus, the consumer receives fuel with strictly limited sulfur content. Obviously, the less sulfur, the more expensive the product. A way to save on the fuel bill is to take lower grade diesel fuel and process it to satisfy the requirements of the vehicle fleet.

GlobeCore offers the desulfurization process based on the AVS-150 magnetic nano-mill and the UVR unit.

The process...


GlobeCore Diesel Fuel Desulfurization Unit

Diesel Fuel Desulfurization. Sulfur is a common component in crude oil, where it can be present both in elementary form and in the form hydrogen sulfide and organic substances, such as disulfides, mercaptan etc. Generally, the influence of sulfur and its compounds on oil products is negative, due to its corrosive properties. That is why it is recommended to eliminate sulfur and hydrogen sulfide and limit the content...


Crude Oil Reforming

In general case, crude oil reforming is the process of converting normal and cyclic paraffins in oil to aromatic paraffins. The process occurs at 500-550ºС in the presence of catalysts. Reforming is necessary to improve the quality of low octane gasoline by increasing the amount of aromatic hydrocarbons.

No refinery operates without catalytic reforming. Since most straight run gasolines are low octane, additional processes are required. Reforming...
