Calculation of gas supply pressure using plastic pipes for preventing accidental emissions

Abstract

Technological (production, operational and repair) risks come to the fore, minimizing which requires optimization of the work of structural units responsible for a reasonable assessment of the technical condition, maintenance and repair of facilities, timely renewal of production facilities with minimization of wear and tear of equipment, which is a risk factor in the failure of the gas transmission system. In addition, based on the noted features of gas transportation enterprises, in the risk management block, logistics risks, safety risks, environmental, social and (in a certain aspect) financial risks should play a significant role. Objectively, in order to establish an acceptable range of risks, it is necessary to collect statistical data on the occurrence of risk factors for the foreseeable period in order to leave for constant monitoring those risk factors that appear regularly in the gas transmission system. The construction and operation of gas pipelines play an important role in the reasonable and technical transportation of gaseous substances. Noteworthy, algorithm for calculating the proposed medium pressure gas pipeline was developed, accordingly, in this research, the gas flow area was determined. The results showed that based on the calculations of underground average pressure of polyethylene pipes, the average gas pressure was 5,733 Pa, withstands pressure was up to 8009.7 Pa, withstands stress on the pipe wall was up to 0.024 MPa, and emission loss was 3964.4 m3 when there was an accident.

Use of artificial intelligence to prevent spontaneous combustion of coal

“…Thus, the statement about the need to create a database for all available coals and the development of an algorithm for using this database to configure detectors can be considered fair. The next step in creating an artificial intelligence system to prevent spontaneous combustion of coal should be the organization of information exchange between producers, consumers, coal custodians and other interested enterprises [26][27][28][29][30][31][32][33][34][35][36][37].…”

Geoecological monitoring of the “Mustaqillikning 25 уilligi” gas field

“…All generated drilling waste enters a waterproofed sludge pit, neutralized with reagents by curing and followed by burial in a sludge pit. The formation of production waste is temporary in nature -only during the construction of the well [6][7][8].…”

“…At each local and background observation point, in accordance with the calendar schedule, samples of atmosphere, surface waters, soils were taken, and radiation measurements were also carried out [1][2][3][4][5][6][7][8][9][10][11].…”
