Increase of dynamic stability of a basis at operation of the compressor equipment of the Abazіvka unit of complex gas preparation

The object of research is the basis of the compressor equipment of the complex gas treatment plant at the Abazivka field and the strengthening of the base soils with soil-cement elements, which are proposed to be arranged with the use of drilling technology. The research area is located on the territory of the current Abazivka Integrated Gas Preparation, near the village of Bugaivka, Poltava region, Ukraine. Abazivka Integrated Gas Preparation receives products from wells in Abazivka and Sementsivske deposits. It is proposed to carry out the reconstruction of Integrated Gas Preparation, which includes strengthening the foundation of the compressor model C1004-JGT/2-1 manufactured by «Propak» (Alberta, Canada). The amplitudes of oscillations of the compressor foundation were determined at a speed of 1400 rpm at the appropriate site with geological conditions. The magnitudes of oscillations and subsidence of the compressor foundation of the Abazivka complex of complex gas treatment were investigated experimentally. When determining the amplitudes of oscillations of the compressor foundations, only the amplitudes of oscillations in the direction parallel to the sliding of the pistons were calculated, and the influence of the vertical component of the perturbing forces was not taken into account. It is established that the amplitude of horizontal-rotational oscillations of the upper face of the compressor foundation relative to the horizontal axis exceeds the maximum allowable. It is substantiated that soil cement is a sufficiently strong and waterproof material that can be used to strengthen the base during the construction of equipment foundations. The possibility of application of the technology of application of soil-cement piles, made by brown-mixing technology for strengthening the base under the foundation of the compressor, is described and investigated. It is proposed to reinforce the base with rows of soil-cement elements, which will increase the modulus of deformation of the base, which is represented by loam, light to 14.3 MPa. In the case of strengthening the base, the amplitude of horizontal-rotational oscillations of the upper face of the compressor foundation is much less than the maximum allowable 0.1 mm. The subsidence of the foundation at reinforcement of the base, which does not exceed the maximum allowable value, is determined. Soil-cement elements are proposed to be arranged according to the drilling technology.

Compressor equipment for enhancing efficiency of solid organic waste processing plants

The article describes the experience of the Compressor holding company in the creation of compressor equipment for various industries. The use of compressors as part of complexes for the processing of organic waste in the framework of solving urgent environmental problems has been demonstrated. The process of compression of synthesis gas to increase the efficiency of the processing process has been investigated. To ensure stable parameters, reliable operation of syngas reciprocating compressors is required in wide ranges of operating parameters. Ensuring the operability of the compressor in wide ranges of parameter variation requires multivariate calculations in order to find the best design parameters of the compressor. A compressor is proposed for the most efficient implementation of the task and its characteristics are calculated.

PROTOTYPING MESH TURBINE WITH THE JET CONTROL SYSTEM

The oil and gas market is unstable, which requires intensification of the exploratory research for working advanced and inexpensive pumping and compressor equipment out. Such equipment is crucial for more efficient hydrocarbon production. The ongoing research work is being undertaken to search and study new technical opportunities to develop advanced pumping and compressor equipment adapted to the complicated conditions of oil and gas production in solid abrasive particles in the flow of the pumped medium. New technology for gas compression has been evolved and further patented. The technology utilized a jet compressor unit to assist a turned on ejector while in the cyclic mode. Pulsed cycling of the ejector in contrary to continuous operation, increases the compression ratio of the multiplied gas. The energy recovery technology has been evolved, and further patented io increase the energy efficiency in the jet compressor unit. This technology applies a particular mesh turbine located at the flow part. The evolvement of smart turbines and compressor units was thoroughly researched. 3D-models have been developed in SOLIDWORKS 3D CAD system. The FloEFD software package of computational fluid dynamics has been used for computer modeling. In laboratory conditions, the performance of the mesh turbine prototype equipped with the jet control system has been successfully tested. Efficient and cheap compressor units solve many urgent issues in production connected with hydrocarbons extraction in harsh environments and those, which occur at the later stages of developing oil and gas fields. Specific research results can be used in other domains, including energy, transport, and robotics.

Exploratory research for developing advanced pumping and compressor equipment adapted to abnormal operating conditions of oil and gas production

The observed instability of the oil and gas market makes it necessary to intensify the exploratory scientific research for the development of advanced and inexpensive pumping and compressor equipment intended for oil and gas production and treatment. The ongoing research work is being undertaken with a view to modernize well-known technical solutions and develop new scientific principles for gas compression with the use of labyrinth compressors. From the published materials, it became known that when designing labyrinth pumps, the screw auger on the pump rotor can be replaced with a set of vane wheels. This design approach should be transferred from the field of pumping technology to the field of compressor technology as well. At the initial stage of such research microlevel models of new turbocompressors have been developed to test their performance. Further, was made the transition from the low-cost physical experiments with micro-level models to a deeper study of the working process for the basic model of the compressor with the screw rotor. 3D-model development was carried out with the use of the SolidWorks 3D CAD-system. In order to undertake a calculation study, the FloEFD software package of computational fluid dynamics developed by Mentor Graphics Corporation has been used. The results of the research findings can be used for the development of energy-efficient technologies for the compression and pumping of various gases. The development of cheaper and more economical pump-compressor units will allow for the solution of urgent hydrocarbon exploration and production problems in abnormal operating conditions. Based on similar compressor units, there is a possibility to develop other sectors of science and technology as well.

Implementation of Integrated Management System in Order to Enhance Equipment Efficiency

The main aim of presented article is to present methodology how sophisticated products as compressor equipment can be considered and analysed as a complex technical system which consists of jointly operating components – a set of hardware, software, operational staff and documented information. In process modelling, these components are interacting in different processes of inputs, outputs, mechanisms (resources) or management. Based on the regulatory requirements for each component of the system, a key efficiency indicator can be identified. This allows to control the process and make appropriate decisions to improve the system. The application of the proposed methodology for the development and implementation of an integrated management system reduce the cost of resources and significantly improve the quality of the implementation of processes.
