Propisani parametri standardne kvalitete plina<\/span><\/span><\/strong><\/h3>\n

Kvaliteta plina odnosi se na kemijski sastav plina i ogrjevnu vrijednost plina, odnosno na parametar standardne kvalitete plina.<\/span><\/span><\/p>\n

Standardna kvaliteta plina propisana je Op\u0107im uvjetima za opskrbu plinom, Prilog br.2.- Tablica 3. (NN 158\/13 i 88\/19)<\/span><\/span><\/span><\/p>\n

Pod standardnom kvalitetom plina smatra se obujam plina od 1m <\/span><\/span>3<\/span><\/span><\/sup> \u00a0pri apsolutnom tlaku plina 101,325 Pa (1,01325 bar) i temperaturi plina 288,15 K (15C).<\/span><\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Utvr\u0111ivanje kvalitete plina na ulazima u distribucijski sustav koji su ujedno i izlazi iz transportnog sustava obaveza je operatora transportnog sustava. <\/span><\/span>
\nPlin neodoriziran (osim plina u distribucijskom sustavu), bez mehani\u010dkih primjesa, smola ili spojeva koji tvore smolu.<\/span><\/span><\/p>\n

Mjerenje kvalitete plina obavlja se kontinuirano opremom za odre\u0111ivanje kemijskog sastava plina i opremom za mjerenje drugih parametara kvalitete plina ugra\u0111enom na specifi\u010dnu to\u010dku transportnog sustava ili povremeno, uzimanjem uzorka plina i analizom istoga u ovla\u0161tenom laboratoriju.<\/span><\/span><\/p>\n

Uzimanje uzorka plina na specifi\u010dnim to\u010dkama transportnog sustava obavlja se dva puta mjese\u010dno i to u razdoblju od 3. do 10. dana u mjesecu iu razdoblju od 16. do 23. dana u mjesecu, pri \u010demu uzorkovanje plina mora biti izvedeno tako da osigura reprezentativan i pogodan uzorak radnog protoka za opremu za utvr\u0111ivanje kvalitete plina.<\/span><\/span><\/p>\n
