INSULATING OIL

Oil Regeneration

Transformers play an essential role in power transmission and distribution. Electricity generated by power plants cannot be supplied to residential and industrial consumers directly. Voltage is increased for long-range transmission and must be reduced before this power can be used for running industrial machinery or powering air conditioners and computers in households. Such transmission ofRead More

Disinfection of wastewater

Disinfection is a complex process of destroying parasites that spread invasive diseases (caused by helminth parasites and arthropods). Sanitary regulations and rules set requirements for deworming/ disinfection. The word “disinfection” came from Latin words “invasio” (invasion) and “des” (from). The quality wastewater treatment is a pressing issue in most countries. The reason is a growingRead More

GlobeCore Engineers Develop a New Cable Oil Processing Unit

110-500 kV OF cables are used for the following purposes: output of power from hydro power plants to distribution facilities; power transmission in high urban density areas, over large bodies of water or areas with severe environmental pollution; power supply to energy-intensive industrial facilities; powering cities etc. Ensuring OF cable reliability requires special equipment forRead More

Urban wastewater treatment

Domestic wastewater of cities and countries is now overwhelming. The sewage treatment facilities have used to the limit all available reserves. The existing technological lines that proved themselves over the years [120, 134] do not cope with the  increased flow of wastewaters. The new sewage treatment facilities are expensive to build. It would seem aRead More

Purification of waste water from phenol and other organic contaminants

In most facilities, such water is purified by oxidizing phenol and other organic contaminants by manganese peroxide, sodium or potassium dichromate at 95-100º С. The oxidation process takes 3 to 5 hours, consuming 5 grams of oxidant per 1 gram of phenol. The purification unit with 12 reactors 25 m3 each can purify 400 to 600 m3 ofRead More

Removal of hexavalent chrome and other heavy metals

The nature of the vortex layer used for treatment of waste water containing hexavalent chrome and other heavy metals allows to radically reduce reagent consumption, achieves a more complete purification and makes the process continuous. Ferromagnetic elements in the active zone of the AVS device, in the electromagnetic field, intensively mix the reagents entering theRead More

Removal of arsenic from waste water

A pressing problem of mining and ore industry is the removal of arsenic from waste water by precipitating it using iron hydroxide or reduction by Na2S, K2S, FeS2. The sedimentation process occurs when a ferrous salt, such as FeCl3, forms a soft amorphous sediment Fe(OH)3 in alkaline environment, which has larger active area. As theRead More

Removal of cyanides

The most toxic waste waters are those containing both simple cyanides (with CN—ions) and complex [Cu(CN2)—], [Cu(CN3)-2], [Zn(CN4)-2] etc. Total concentration of simple and complex cyanides varies from 10-15 to 150-300 mg/liter. The most widespread method today is reagent method of oxidation by calcium hypochlorite Ca(OCl)2, hypochlorite lime CaOCl2 or gaseous chlorine. Most of the cyanide-containing waterRead More

Removal of fluor and nitric compounds from waste water

Research performed in the area of decontamination and fluor removal from waste water using AVS shows (table 5) that these devices are more efficient compared to the existing equipment. Fluor removal and transformation of phosphates into water-insoluble compounds occurs in one stage. The content of fluor in purified waste water in optimal conditions (pH =Read More

Neutralization of wastewater containing petroleum products

Wastewater containing petroleum products are among the most difficult to neutralize.. Especially difficult for processing are wastewaters containing, in addition to petroleum products, metal shavings, sand, rags and other inclusions, both solid and liquid. Therefore, wastewater is very difficult to classify. In some cases, they are divided into types: “flammable” or “non flammable”. For example,Read More

Water purification

The conditions created in the processing area of the AVS allow to carry out practically any technological processes. The plants are particularly effective in industries that require rapid and uniform mixing (especially if the content of components is calculated in units or percentages) where it is necessary to treat suspensions (heterogeneous systems) regardless of theirRead More

GlobeCore in the Press: Portland cement regrinding in vortex layer device (Cemento Hormigón Magazine)

The May-June 2018 number of Cemento Hormigón Magazine of Spain features an article by GlobeCore electrical engineer José Mora, titled “Re-trituración y mejora del cemento portland en los sistemas de optención de la capa vórtex de particulas ferromagnéticas”. The article describes GlobeCore experience in application of the vortex layer devices with ferromagnetic elements in theRead More

Commissioning of a Bitumen Emulsion Unit in Myanmar

In July 2018, a GlobeCore USB-2 unit was commissioned in Myanmar. Beside the commissioning, GlobeCore engineers also trained customer personnel to operate and service the unit. The unit produces 8 cubic meters of emulsion per hour; it consists of a water phase section, emulsion preparation section, controls and piping to supply water phase solution andRead More

Special Aspects and Differences of Transformer Oil Regeneration in GlobeCore MCU and CMM-R units

GlobeCore offers several models of transformer oil regeneration units. This article looks into the differences between regeneration in MCU and CMM-R types. Application The MCU units are designed for partial regeneration of transformer oil, which includes removal of water, water-soluble acids and particulate matter. The CMM-R, on the other hand, performs complete regeneration, including removalRead More

Transformer oil filling

The term “transformer oil filling”, as it is used in this article, has two meanings. The first is the process that compensates for the loss of oil in the course of transformer operation. The second is filling a transformer with oil before commissioning or after an overhaul. Oil is an essential part of the transformer.Read More

Insulating Oil Clarification Systems

Insulation oil is a general term for industrial oils used in high voltage systems. This groups includes transformer, capacitor and cable oils. This article looks into the features of such oils and insulating oil clarification systems. Transformer oil is widely used in modern transformers as an insulation and heat dissipation medium. It also protects celluloseRead More
