In this article, the calculation of diffusion processes for five natural hydrocarbon gas mixtures into the air was carried out. The effective diffusion coefficients and matrix coefficients of multicomponent diffusion were determined. Also the advantages of using effective coefficients in the description of mass transfer were shown.</jats:p></jats:abstract><publication_date media_type="online"><month>5</month><day>25</day><year>2021</year></publication_date><publication_date media_type="print"><month>5</month><day>25</day><year>2021</year></publication_date><pages><first_page>61</first_page><last_page>68</last_page></pages><ai:program xmlns:ai="http://www.crossref.org/AccessIndicators.xsd" name="AccessIndicators"><ai:free_to_read start_date="2021-05-25"/><ai:license_ref applies_to="am" start_date="2021-05-25">https://www.naun.org/main/NAUN/mechanics/2021/a142003-007(2021).pdf</ai:license_ref></ai:program><archive_locations><archive name="Portico"/></archive_locations><doi_data><doi>10.46300/9104.2021.15.7</doi><resource>https://www.naun.org/main/NAUN/mechanics/2021/a142003-007(2021).pdf</resource></doi_data><citation_list><citation key="ref0"><unstructured_citation>D.
