The analysis of the use of selective non-catalytic reduction technology for the reduction of nitrogen oxides (SNCR) in the world is carried out. It is shown that the effectiveness of SNCR systems in industrial conditions (25…65 %) is significantly lower than theoretically possible (90…95 %). The reasons of insufficiently high efficiency in the application of SNCR process in industry are investigated.

It is shown that the introduction of the reducing agent solution in the high-temperature zone in almost all SNCR installations is carried out by means of atomizer type distributing units in the form of a droplet phase. At the same time, the processes of heating the droplets, evaporation and decomposition of the reducing agent solution occurring in the flue gas flow require a certain time, which reduces the time of direct interaction of nitrogen oxides with the reducing agent.

The authors propose the possibility of increasing the time of nitrogen oxides reduction process by pre-heat treatment of the reducing agent aqueous solution in a special device-evaporator-homogenizer, which serves for evaporation and thermal decomposition of the solution due to the heat of superheated steam, as well as to create a homogenized steam-gas reducing mixture. The reducing mixture obtained in the evaporator-homogenizer is introduced into the calculated cross section of the gas flue of the unit. This method of preparation of the reducing mixture allows to increase the time of the main reaction of nitrogen oxides reduction and thereby increase the efficiency of the gas cleaning process.

In addition, the authors propose to introduce the reducing agent into the flue gas flow through special distribution devices with critical flow rates, which allow to achieve practically instantaneous and uniform distribution of the reducing agent in the flow of cleaned gases.

Examples of the proposed technological solutions use in the implementation of SNCR systems on thermal units for various purposes, which led to a significant increase of the process efficiency are given.

 

Keywords: nitrogen oxides; SNCR technology; cleaning efficiency; introduction of reducing agent; time of the process implementation; preparation of the reduction mixture; critical flow rate.

It was conducted the analysis of long-term (1981–2016) data on the content of priority for the Volga-Caspian basin toxicants in the tissues and organs of sturgeon species fishes. The dynamics and selectivity of cumulation of hydrocarbons, heavy metals and pesticides were revealed against the background of changes in the ecological and toxicological situation, transformations at the population and organism level. It were installed periods of increasing the accumulation of toxicants in the body of sturgeon, which occurred both at the stage of exploration of oil and gas fields, and at the stage of their industrial development. The ecological state of the aquatic environment is estimated taking into account the coefficient of accumulation of hydrocarbons and metals in the body of fishes.

The main cause for the deterioration of oilfield equipment and communications is corrosion. In addition to the development of technological methods of equipment protection, modeling of the metal surface corrosion mechanisms is being actively developed today and the involvement of cellular automaton models can serve as an addition to the already used methods.

We consider the cellular automata on triangulation grids modeling three-dimensional natural processes, in particular corrosion, on a cylindrical surface that simulates a fragment of a pipeline.

The described approach can serve as a basis for the modeling of various phenomena, not limited to diffusion processes. Obtained results are used to construct more complex compositional CA, in which diffusion acts as one of the transition rules, CA-models of the diffusion front propagation and diffusion limited aggregation are constructed.

We also created an application that implements the constructed models, and allows the transition from boolean values to continuous functions of the particle concentration distribution, performed by averaging the state values of the automata cells with neighboring cells values, as well as an inverse process called discretization. The results of computational modeling show that the implemented cellular automata are not qualitatively inferior to CA on rectangular grids and at the same time allow the modeling of processes on the surfaces with complex geometry, for example, the surfaces of pipeline communications.

 

Keywords: triangulation; cellular automata; naive diffusion; front propagation; diffusion limited aggregation; pipeline surface; corrosion.

In this article, one of the problems of assessing the negative impact of works on the development of the field by the enterprise of the oil and gas complex and identifying sources of pollution in the organization of the production process on the shelf is solved.

It is known that the peculiarity of water circulation in the basin of the Azov Sea is the presence of zones of convective motions, both free and forced, in the general field of plane-parallel flows. To simulate the process of transporting pollutants, a boundary problem is posed, including a system of Navier–Stokes equations for determining velocities in a vortex cell and a system of equations for transferring satellites in cylindrical coordinates to study the dynamics of concentration in a vortex cell if the pollutants flux is fed from a cylindrical boundary. To solve this problem, we propose a numerical-analytical method for studying the processes modeled by mixed boundary value problems, which include models of turbulent diffusion.

The analytical solution of the system of Navier–Stokes equations to determine the velocities in the vortex cell is obtained. Numerical calculations to determine the concentration of pollutant were performed in three ways: by the block element method, by the method of integral transformations, and the problem was solved by means of the software package FlowVision 2002. General tendencies were determined and conclusions were made about the possibility of using each of the methods.

 

Keywords: oil and gas complex enterprise; water quality; environmental monitoring; mathematical model; transfer; convective flow.

The use of oil-based drilling fluids (OBF) allows for trouble-free drilling of wells in the most difficult mining and geological conditions. One of the main problems hindering the widespread use of OBF is a high technogenic load on the environment due to the absence of cost-effective technology for utilization of waste fluids of this type, which allows for the recovery and recycling of expensive components of OBF. Spent OBF are stable invert emulsions, the separation of which is a complex technological problem. It is preferable that the utilization technology allows to divide OBF into separate phases in the field conditions by gravitational sedimentation. This prevents significant investment in additional expensive equipment.

The paper presents the results of development and pilot-field tests of the technology for utilization of spent OBF, which provides for their separation into the hydrocarbon and water phases, followed by the complete re-use of these phases in the production cycle. The technology provides for multiple use of all components of OBF and minimizes volume of drilling wastes for transfer to specialized organizations for utilization.

 

Keywords: oil-based drilling fluid; utilization; demulsification; drilling wastes; demulsifier for the natural water-oil emulsions.

The results of the study of the investigation of the properties of polymeric sorbents of the “Unipolymer-M” series and on the basis of the non-woven fibrous sorbents “Ecosorb” used for the liquidation of oil spills in water areas, the sorption properties of thesesorbents under various temperature conditions. Investigation have established the effect of temperature on the sorption of oil by fibrous and loose polymeric sorbents, and the choice of sorbent recommended from oil in the conditions of the Arctic zone is justified. Confirmation of the relevance of this work is the tendency to increase oil production on platforms in the seas and oceans, increasing interest in the Arctic zone of Russia. Extraction of oil on the shelf, as well as its transportation in water areas, is accompanied by risks of oil spills during its production, as well as during storage and transportation of oil and oil products due to man-made accidents and natural emergency situation.

 

Keywords: polymeric sorbents; sorbent structure; elimination of oil spills; Arctic zone.
