Virtually any production is accompanied by large amounts of waste which can be reused after undergoing appropriate treatment.  It is  predicted that in the future, the new raw materials will be recycled from industrial waste. Used lubricant oil (ULO) is liquid waste product.  ULO is any oil derived from crude oil or synthetic oil, contaminatedRead More

Waste Oil Collecting and Reclaiming

Lubricating oil is practically always exposed to contamination during operation of machinery.  Wear and tear are the first cause of contamination.  Contaminated oil loses its resistance to oxidation,  loses its lubricating properties and increases wear of the rubbing surfaces. Lubricating oil is constantly under  the influence of high temperatures, atmospheric oxygen and deterioration products.  TheRead More

Rational Use of Spent Lube Oils

This article analyzes modern approaches in saving fuel and energy resources. Used oil recycling is the most promising way to preserve valuable raw materials. GlobeCore recycling technologies help reduce consumption of fresh oil by 25-30% and provide significant savings on purchase of  new lubricants. World oil reserves are constantly decreasing. Costs of oil production isRead More

Transformer oil restoration

Transformer oil is used in power transformer an oil filled switches. This oil facilitate insulation of energized parts of the equipment, heat dissipation and arc extinguishing. The dangers of transformer oil contamination Electric power experts agree that the life time of a transformer lasts only as long as the life time of its insulation system.Read More

Silica Gel for Air Drying

Only porous materials,  having a large specific surface, can be adsorbents. To dry air – silica is most commonly used. Silica gel is a result of dehydration of sodium silicate. The specific surface area of this adsorbent is 400-770 m2 / g and granule size – 0,2-7 mm. At the end of its effective operationRead More

Cleaning and Drying of Natural Gas

The presence of impurities and moisture in natural gas is highly undesirable because it can adversely affect the transportation as well as  complicates its operation as fuel and raw material. Also, this process removes pollutants of the environment.  They are carbon dioxide, hydrogen sulfide and sulfur dioxide. Natural gas should be purified to the contentRead More
