Crystalline Hydrates

The existing methods for natural gas dehydration both in fields and at compressor stations cannot always provide standatdized values of natural gas dehydration. The analysis of operation of gas distribution systems shows that dehydration units are improperly placed and are often installed out of condensation and freezing zones. This is due to the lack of consideration of phase transitions impact in gas throttling on its temperature condition. Due to insufficient natural gas dehydration, crystalline hydrates can be formed on wellbores, distribution lines and main gas pipelines and at its reduction, disturbing the operation of the equipment of compressor stations, gas distribution stations, deranging instrumentation and automation. The issues of reliability of gas pipeline systems considering the formation of crystalline hydrate plugs in pipelines have been studied. The analysis of the methods and devices preventing hydrates formation and eliminating existing crystalline hydrate plugs has shown that to provide normalized parameters of the transported gas it is necessary to perform additional water vapor, condensate drops and crystalline hydrate particles removal from natural gas at gas distribution stations during winter months. Currently applied methods used to deal with crystalline hydrate plugs in main gas pipelines require significant expenses and do not effectively ensure the reliability of pipelines operation. An energy-efficient design of an integrated treatment unit which provides an additional natural gas treatment at GDS, increases the reliability of gas pipelines protection against hydrate blockage and improves the efficiency of gas supply systems as a whole have been proposed at the Department of Heat and Gas Supply and Ventilation of the SWSU.

Introduction. A promising direction in the development of gas supply systems, which is widely used in the developed countries of the world, is the use of an alternative energy source — biomethane. The effective use of biomethane requires the development of scientific provisions and recommendations for the use of biomethane gas supply systems, taking into account technical and economic factors. Therefore, it is urgent to develop an economic and mathematical model for choosing a gasification method and determining the area of rational use of gas supply systems with biomethane. Materials and methods. To develop an economic and mathematical model for choosing a method for gasification of settlements, methods of mathematical modeling and parametric optimization were used. The implementation of the economic and mathematical model was carried out in the Mathcad software package. Mathematical and graphic processing of the results obtained was carried out. Results. An economic and mathematical model was developed for determining the rational area of application of biome­thane for gas supply to settlements. The model is based on the technical and economic calculation of the reduced costs for gas supply systems with network natural gas and biomethane. Using the developed model, the technical parameters of the biomethane gas supply system were determined: the critical length of the gas pipeline branch, the radius of the biomethane plant, the biomethane consumption, the length of the gas pipeline for the biomethane supply, and the reduced costs to the gas supply system. A graph of the dependence of the critical length of the gas pipeline branch on the population size has been obtained, which makes it possible to determine the area of rational use of biomethane for gas supply to settlements. It was found that for a rural settlement with a population of 5,000 people, the critical length of the gas pipeline branch is 24.820–28.044 km, for an urban-type settlement with a population of 15,000 people, the length of the gas pipeline branch is 50.923–64.677 km, and for a city with a population of 30,000 people — 89.617–127.279 km. Conclusions. The results obtained can be used for the development and design of gas supply systems based on biomethane for the gasification of settlements remote from the main gas pipelines. The use of biomethane makes it possible to gasify settlements in developed agricultural regions and to increase the efficiency of the gas transportation system of the Russian Federation.

AbstractThe purpose of this study is to develop a natural gas simulation model for costs optimization. The main focus of the model is on the transmission system since its imbalance leads to the penalties which must be paid by the suppliers. The total nominated amount of natural gas (the gas injected into the transmission system) must be consumed (withdrawn from the system) in order for the system to be in balance. In practice, this is not the case since it is very hard to accurately predict the future hourly consumption (in order to make a nomination) and certain deviations appear which leads to the imbalance. However, this problem could be solved by introducing a special electromotor valve which would be placed at the beginning of the distribution system and control the accumulation of the system. To test this solution, a simulation model was created using Arena Simulation tool. Data for the simulation model are collected by the natural gas distributor and consist of natural gas consumption and nomination values for one measuring-reduction station on the hourly basis. Thus, the final dataset includes 8.754 records. The separate As-Is and To-Be models for seven (summer) months were made and the results were compared. The simulation experiment shows that the positive rebalancing energy would be reduced by 32%, and the negative one by 34%. The created model can serve as a good initial step for the analysis of the justification of investment in the implementation of a technical solution that would manage the accumulation of the distribution system.

In order to guarantee future supplies, PETROBRAS is deploying the Gas Production Anticipation Plan – PLANGAS which will increase domestic gas supply to the South-South East regions. Mexilha˜o Field is considered strategically for the Brazilian market gas supply chain, as it is one of the five production complexes to be installed at Santos Basin and have production forecast for up to 15 million m3 of gas per day and twenty thousand barrels per day of natural gas condensate. Mexilha˜o platform - PMXL-1 will be installed at 172 meters water, will export the gas production through 34 inches pipeline with 146 kilometers of extension from the off-shore unit up to an on-shore gas treatment facility, called Unidade de Tratamento de Gas Monteiro Lobato - UTGCA at Caraguatatuba, Sa˜o Paulo. The Gas Treatment Plant will have a processing capacity of 15 million m 3 per day of gas on its first stage, and will produce, as end products specified natural gas for consuming, liquefied natural gas (LGN) and the condensates, such as C5+. After processed in the UTGCA, the natural gas will be dispatched through a 26 inches pipeline up to a future Taubate´ Compression Station at Taubate´, SP, to be connected to a main gas pipeline called GASTAU. This 26″ pipeline is about 100 kilometers long, from Caraguatatuba to Taubate´. This paper intent to present the implementation of such enterprise, where it is affecting at least three different segments within PETROBRAS. The main challenge will be to integrate different requirements and specifications from those three segments and their supply chain, in ways that the overall figure does not impact the enterprise and the time schedules, requirements and operation wise work. Those three segments E&P, Gas and Energy BU, Transport, will also interact with a fourth player, PETROBRAS Engineering department, responsible to contract the engineering design, construction and assembly of all parts, following each segment standards. The main goal of such work is to achieve a process data real time collection, visualization and operation, coming from different sources as gas pipelines, process operations and measurement, with efficiency and reliability to fulfill each segment requirements in an integrated way that no duplication or waste of money and time occurs.

Background: With the development of natural gas and shale gas worldwide, the consumption of gas will continue to increase in the future. Natural gas is flammable and explosive, and the exhaust gas produced during the combustion of natural gas in boiler burners is one of the main sources of NOx in the air. Objective: This paper introduces patents and researches of natural gas boiler burners to improve the safety of natural gas boiler burners and reduce the emission of nitrogen oxides. Methods: In summarizing the existing boiler burner for natural gas, this paper introduces three new patents of natural gas boiler burner: the low-nitrogen burner, the energy-saving leakage-detecting burner and the small boiler burner. Results: The low-nitrogen burner identifies the fixed control of gas flow, enhances the gas flow’s antiinterference ability, and achieves a relatively accurate ratio of the fuel-air flow. The energy-saving leakage-detecting burner enhances the natural gas and air flow stability and improves combustion efficiency and the safety and reliability by optimizing the ratio of natural gas to air. The small boiler burner improves the safety and reliability of the natural gas boiler burner, prolongs the service life of the igniter, and makes up for the shortcomings of high stability in the gas pressure. Conclusion: On the basis of ensuring the safety of the burner, the low-nitrogen transformation of the boiler burner is as energy-efficient as possible in order to maximize the advantages of natural gas resources.

There are investigated the influence of operating pressures in the gas supply system on the level of such energy indicators as efficiency, gas flow and gas overrun by gas equipment in residential buildings. There is established a relationship between the values of operating pressures in the gas supply system and the gas consumption level of household appliances. The causes of insufficient pressure in the gas networks of settlements are analyzed in the article. There is also developed an algorithm for calculating the change in the efficiency of gas appliances depending on the operational parameters of the gas network. It has been found that the most efficient operation of gas appliances is observed at an overpressure at the inlet of gas appliances of about 1200 Pa.To ensure the required quality of natural gas combustion among consumers and minimize gas consumption there are justified the following measures in the article: coordinating a domestic regulatory framework for assessing the quality of natural gas with international norms and standards; improving the preparation of gas coming from local wells before supplying it to gas distribution networks; auditing low pressure gas pipelines and reconstructing areas affected by corrosion; ensuring standard gas pressure in the network for the normal operation of domestic gas appliances; stating quality indicators of natural gas combustion by gas sales organizations.
