Patent
Lublin University of Technology, Wrocław University of Environmental and Life Sciences | Date: 2017-08-02

A method of producing hydraulic fracturing fluid from wastewater obtained during the shale gas extraction is disclosed wherein H_(2)O_(2) is added to the flowback water which is then mixed until the redox potential of 700-720 mV is achieved; then the 5% Ca(OH)_(2) suspension in 10% solution of NaCO_(3) is added and intensively mixed to obtain pH of 11.15 0.15, the precipitate is then separated by a known method, most preferably by means of a centrifuge.

A method of producing hydraulic fracturing fluid from wastewater obtained during the shale gas extraction is disclosed wherein fresh water is added to flowback or produced water until desired salinity is achieved which is then followed by adding H_(2)O_(2) in the amount related to BOD. CaO is used to adjust pH and then sediments are precipitated by intensively mixing them with solution of Na_(2)CO_(3) or K_(2)CO_(3), the precipitates are then separated in a centrifuge and solution of H_(2)SO_(4) is added to the clarified water in order to obtain clarified solution.

The main research goal of the NEWEX Project is the construction and testing of the new innovative extruder. By the application of a new, patented concept of vital parts: innovative active grooved feed section (IAGFS), original rotational barrel segment (ORBS) and special screw (SS) a completely new breakthrough technology of extrusion and plasticizing systems will be achieved. It will ensure manufacturing the products of improved properties and will enable processing materials that couldnt be processed so far, as well as food materials, cosmetic and pharmaceutical. In parallel to the main RTD activities the NEWEX project is aiming at industry-academia cooperation and transfer of knowledge between organizations from central-eastern and Western Europe. All the projects activities will be performed by thoroughly planned secondments and appropriate hosting institutions between industrial and academic partners. The workplan consists of 7 Workpackages, out of which: WP1-4 focus on the investigation of extruder, extrusion process and extrudate properties and tasks aiming at the selection of the best solution of new extruder vital parts, than construction and testing of new generation extruder. WP5 concentrates on networking activities (workshops, training, knowledge exchange, etc.). WP6 aims at knowledge dissemination (participation in conferences, fairs, publications, etc.), WP7 is dedicated to management and administration of the whole project. The consortium consists of 6 organizations: 3 representing academic partners and 3 representing industry partners. Project is coordinated by Lublin University of Technology (Poland). Partners are: Technical University of Kosice (Slovakia), University of Minho (Portugal), Zamak-Mercator LLC (Poland), SEZ-Krompachy a.s. (Slovakia) and Borra s.r.o. (Czech Republic). Realization of NEWEX project will foster the real industry-academia cooperation which is of the key importance in terms of European Research Area development strategy.


Patent
Lublin University of Technology, Wrocław University of Environmental and Life Sciences | Date: 2016-01-27

Invention relates to a production method of soil substitute for reclaiming mining excavations with the use of waste drilling fluid, which is characterized by mixing waste drilling fluid in the amount of 30-50% by volume, preferably 50% with 50-70% by volume of sludge from sewage treatment plant, preferably 50%, the mixture is then separated using a centrifuge, wherein the liquid phase is separated from the solid phase; the former is redirected for treatment and the latter is mixed either with calcium oxide amounting up to 10% of weight or with coal ash amounting 15-30% of weight and the obtained product is mixed with ground gangue so that its contents amounted to 65-90 % .

Patent
Lublin University of Technology, Wrocław University of Environmental and Life Sciences | Date: 2016-02-03

The method of reclaiming excavations after the mineral resources exploitation is characterized by filling an excavation with a mixture of coal bed rocks, drill cuttings and ash to the level of 1-2 m below ground. Afterwards, a 1-2 m layer of artificial soil is created from cuttings separated from drill liquid, biological wastewater treatment plant sludge and top soil accumulated during the preparation for exploitation. In the artificial soil drill cuttings are present in the amount of 10-30%, preferably 20%, sludge is present in the amount of 20-40%, preferably 30%, and top soil is present in the amount of 30-60%, preferably 40%.
