Enhancing liquefied petroleum gas production through debutanizer column optimization

Debutanizer columns are important in natural gas processing as they are crucial in generating Liquefied Petroleum Gas (LPG). LPG is well recognised for its environmentally benign combustion properties, making it a desirable fuel option for cooking, heating, and transportation. The optimisation of debutanizer units has significant relevance in improving the efficiency of LPG separation. This study aims to enhance the separation efficiency of a butane removal tower by modelling and optimising its operation using HYSYS software. The research aims to introduce innovation in this field. A series of comprehensive simulations were carried out to achieve this goal, resulting in outcomes that nearly corresponded to the findings obtained from natural gas units. Moreover, a thorough examination was conducted to examine the impact of temperature, pressure, feed flow rate, and reflux ratio on the production yield of n-butane. The study reached this conclusion by optimising tower conditions, with a particular emphasis on improving the performance of the condenser during the hot summer season. In ideal circumstances, the distillate demonstrated a butane concentration ranging from 70% to 74%, while all overhead gas is condensed in all instances. This study highlights the importance of optimising the debutanizer column in enhancing the quality and efficiency of LPG production in the natural gas processing sector.

Модели надежности электроснабжения объектов нефтедобычи

This paper presents power supply systems reliability models of oil production facilities. There are two types of electrical complexes: an electrical network with a consumer sensitive to voltage dips and an electrical network with a consumer with technological redundancy. A comprehensive analysis of the power supply system and the power consumer allowed us to clarify the reliability indicators and determine the direction of improving the power supply reliability to oil and associated petroleum gas production facilities

MODELING THE HEAT TRANSFER PROCESS IN REFRIGERATION UNITS USED IN THE OIL INDUSTRY

Currently, the main volume of associated petroleum gas production in Azerbaijan is carried out at offshore fields. About 30 % of this volume is used for SOCAR’s own technological needs of the oil company (to maintain the level of oil production). And the rest are transported to onshore facilities and further for processing to a gas processing plant. Subsequently, dry and purified gas is sent through a gas pipeline system for use by the population, or to a network of trunk pipelines for further export. When gas is transferred to the gas lift system and ashore, it is compressed in compressors, as a result of which the temperature of the working agent rises. The latter dramatically reduces the level of operational safety of the entire process. Based on the foregoing, ensuring the required gas quality at the outlet of the compressor unit is an important and urgent task. Currently used in the gas cooling system, shell-and-tube type refrigeration units have several advantages: high heat transfer coefficient, operability in low and high pressure modes, simplicity of design and service. Along with this, these units are distinguished by large dimensions and high metal consumption, noise effect, vibration, etc. A new design of a heat exchanger for cooling associated petroleum gas at the outlet of gas motor compressors is proposed. Based on the modeling of the heat transfer process, mathematical models have been obtained that make it possible to adequately evaluate the cooling process in the proposed refrigeration device.

Legal regulation of environmental protection and ensuring environmental safety when using underground resources at regional and local levels

The article deals with environmental and legal problems of using underground resources, particularly associated petroleum gas. Today regional legislation develops unsystematically and inconsistently, because the powers of the constituent entities of the Russian Federation are regulated insufficiently in the sphere of environmental protection and ensuring environmental safety, when using underground resources. Some cases contain direct contradictions to federal legislation. Some constituent entities of the Russian Federation have a tendency for normative legal regulation of this area of public relations within the framework of "advanced standard-setting". These tendencies show the need to specify the powers of the constituent entities of the Russian Federation in federal legislation. Disposal of associated petroleum gas is becoming a serious problem today. A great part of this gas is wildly flared getting into the atmosphere, whereas there is a more decent and even profitable way of its disposal. The article analyzes the corporate structure of associated petroleum gas production in Russia and determines the directions for improving the legal framework. Based on their research, the authors propose to develop a Program of implementing a set of measures aimed at increasing the extraction and subsequent processing (disposal) of associated petroleum gas by independent oil companies, which could serve as measures for state stimulation of oil production development.

Household air pollution and the sustainable development goals.

Globally, 41% of households, over 2.8 billion people, rely on solid fuels (coal and biomass) for cooking and heating. In developing countries in Asia and sub-Saharan Africa where these fuels are predominantly used, women who are customarily responsible for cooking, and their young children, are most exposed to the resulting air pollution. Solid fuels are still in widespread use and it appears that intervention efforts are not keeping pace with population growth in developing countries. Here we pinpoint the challenges and identify opportunities for addressing household air pollution while mitigating global climate change and promoting the sustainable development goals. We recommend the following actions: implementation of the WHO indoor air quality guidelines on household fuel combustion; effective promotion and dissemination of improved cookstoves through formation of country alliances for clean cookstoves; expansion of liquefied petroleum gas production facilities and distribution networks; harnessing renewable energy potential; promotion of biogas production at both household and community level; ensuring improved ventilation of homes through education and enforcement of building standards; and exploiting opportunities in the health and other sectors for changing health-damaging cooking behaviour.

Reaction Processing of Fraction of Yanhua FCC Gasoline

By using fraction of Yanhua FCC gasoline as a feedstock, the effects of reaction temperature, weight hour space velocity, feedstock performance on yields of liquefied petroleum gas production, and aromatics and propylene are researched in a confined fluidized bed reactor. Aromatization index (AI) and competent parameter (CP) are first proposed to study the mechanistic pathways of aromatization reaction of fraction of Yanhua FCC gasoline. The experimental result shows AI values of FCC gasoline decrease with the increase of the reaction temperature under the same catalyst; CP values and the aromatization reaction function for the same catalyst increase with the increase of the reaction temperature. The isomerization reaction for fraction of Yanhua FCC gasoline has more advantage than that of the aromatization reaction.
