Yejing Gong as a doctoral candidate come from China University of Petroleum(Beijing). He is the director of enhancing heavy oil recovery.
Recent studies have revealed that nanoparticles can alter the viscosity and rheology of polymer aqueous solutions, thus improving the displacement of crude oil. Here, we present our work on the synergistic effect of nano-SiO2 and a novel hydrophobically modified polymer (HMP), namely, HMP–fatty alcohol polyoxyethylene ether (AEO15), on enhancing heavy oil recovery. In this work, the effect of nano-SiO2 on the rheological property of the HMP–AEO15 aqueous solution was studied. Then, the emulsification effect of the single HMP–AEO15 and HMP–AEO15+SiO2 composite on heavy oil were evaluated from different items. A micromodel was further utilised to investigate the efficiency of the single and composite solutions in heavy oil displacement. Results showed that the addition of nano-SiO2 could improve the viscosity, temperature and shear resistance of the HMP–AEO15 aqueous solution. The composite could simultaneously reduce interfacial tension and increase interfacial viscoelasticity between the oil and water phases. The heavy oil emulsion prepared with the HMP–AEO15+SiO2 composite had a narrower size distribution and better stability than that prepared with the single HMP–AEO15+SiO2 solution. Heavy oil recovery in the different parts of the micromodel after composite flooding increased by 5.98%–16.95% relative to that after single HMP–AEO15 flooding. This work proved that the HMP–AEO15+SiO2 composite has great potential for application in enhancing heavy oil recovery.
I have a master's degree in machines and devices for chemical production (Kazan Technological University, Russia). I am the director of Electrol-S LLC. The company is engaged in the development of separation equipment. I have 6 patents and over 10 articles.
The following innovations have been introduced in the gravitational-dynamic emulsion separators developed by Electrol-S LLC: the column of heavy and light fractions balances the column of the heavy fraction; a new coalescence filter scheme has been applied - partitions are installed in a checkerboard pattern. Thanks to these innovations, the interface between the phases of liquids is always in the optimal position and is not additionally controlled, and the emulsion is divided into two fractions and discharged from the apparatus in any proportions without using automation. The following projects can be identified for implementation: 1) development of HD-separators for petrochemical purposes, for example, for the purification of disulfide oil from an alkaline solution or light pyrolysis resin from water, etc., 3) reconstruction of existing sedimentation tanks for oil production, 4) development of a standard line of HD -separators for the treatment of formation water (oil production), 5) development of HD-separators for the purification of diethylene glycol from resinous impurities (gas production), 6) development of HD-separators for offshore platforms, 7) development of a marine vessel for collecting oil from the water surface at spills in case of accidents on the shelf or during transportation by tankers, 8) development of equipment on the basis of a boat for the purification of coastal waters, 9) development of HD-separators for water purification from oil products and fats - the first stage of treatment facilities, 10) local treatment facilities

Water is such a unique element on planet earth. Water is considered as the torch bearer of human mankind and hence it is the most sought after in terrestrial spaces. Water in its purest form is completely transparent, odorless and neutral. However, it is seldom that we find all such properties of water in its natural existence. With the increasing industrialization and increased population pressure more and more industries are being setup to serve the mankind for their livelihood. This in turn is causing a lot of contamination to water sources resulting in health hazards. Not only human beings, but all living beings including animals and birds also get impacted due to this. Various contaminants get mixed with water and it becomes necessary to remove these toxic water pollutants before water is being consumed.
The methods to remove heavy metals from aqueous media can be grouped into two broad categories. The conventional methods fall under the physico-chemical approach. These methods can be carried out on a large scale but have their limitations. The other category which is the focus of this review explores biological methods used to remove heavy metals. This approach is called bioremediation. Bioremediation can involve various methods and can be grouped into phytoremediation (using plants) and microbial remediation (using microbes). This review describes some methods under bioremediation, mainly biosorption and bioaccumulation, and the differences between these methods. To improve the efficiency of these methods, some techniques have been discussed. These are immobilization and modifications of the cell wall. Scope for our experimentation is mentioned for further study in the area.

This communication discusses a comprehensive review of biomass energy sources, environment and sustainable development. This includes all the biomass energy technologies, energy efficiency systems, energy conservation scenarios, energy savings and other mitigation measures necessary to reduce emissions globally. This study highlights the energy problem and their possible saving that can be achieved through the use of biomass energy sources. Also, this study clarifies the background of the study, highlights the potential energy saving that could be achieved. The use of biomass energy source describes the objectives, approach and scope of the theme. However, to be truly competitive in an open market situation, higher value products are required. Results suggest that biomass technology must be encouraged, promoted, invested, implemented, and demonstrated as a whole while especially in remote rural areas.
