Abstract

Bioplin je smjesa nekoliko plinova, pri čemu metan i ugljikov dioksid čine 90 % ukupne smjese, a prisutne su i manje količine sumporovodika, dušika, vodika i kisika. Dobiva se iz procesa anaerobne digestije u digestoru ili raspadanjem organske tvari na odlagalištu otpada. U ovom radu prikazane su opasnosti do kojih može doći na postrojenjima bioplina, zone opasnosti kod dobivanja bioplina iz digestora i kod dobivanja bioplina s odlagališta te primjeri uređaja i oprema koja se koristi kod bioplinskih postrojenja. Potencijalno ugroženi prostori moraju se svrstati u zone opasnosti. Osim osnovne norme (HRN 60079-10) za klasifikaciju prostora može se koristiti niz od pet dokumenata ICoP (Industry Codes of Practice). Svrha ICoP dokumenata je da daju detaljne smjernice kako provesti klasifikaciju prostora na bioplinskim postrojenjima, vodeći računa o svim posebnostima prostora gdje se može javiti bioplin. U radu su prikazane jednadžbe i primjer proračuna opsega zone.

Abstract (english)

Abstract: Biogas is a mixture of several gases, wherein carbon dioxide and methane make up 90 % of the total composition, and there are also small quantities of hydrogen sulphide, nitrogen, hydrogen and oxygen. Biogas is obtained from anaerobic digestion process in the digester or it can be obtained by decomposition of organic substances in the waste landfill. In this thesis are described the dangers that can occur in biogas plants, the danger zones where biogas is obtained from the digester and biogas from landfills and examples of devices and equipment used for biogas plants. Potentially endangered areas must be classified as danger zones. In addition to the basic standard (EN 60079-10) for the area classification a series of five documents ICOP (Industry Codes of Practice) is used. The purpose of the ICoP documents is to provide detailed guidance on how to make area classification in biogas plants, taking into account for all relevant information on area where biogas can appear. In this thesis are given relevant equations and examples of zone radius calcualtion.
