Oblast primene prirodnog gasa je veoma široka. Kao energent može se koristiti za proizvodnju energije u elektranama, toplanama i postrojenjima za kombinovanu proizvodnju energije ili za zadovoljavanje različitih toplotnih potreba u industriji i širokoj potrošnji. Gas se može upotrebiti i kao sirovina u hemijskoj i petrohemijskoj industriji, a tokom poslednjih decenija nalazi primenu i u saobraćaju kao pogonsko gorivo u SUS motorima. Sa ekološkog stanovišta, prirodni gas predstavlja najprihvatljiviji izvor energije u poređenju sa drugim fosilnim gorivima. Pri sagorevanju prirodnog gasa, zbog njegovog hemijskog sastava, emituje značajno manje ugljendioksida po jedinici proizvedene toplotne energije, nema pepela i emisije čestica, a emisija sumpordioksida je zanemarljiva. Prirodni gas često se naziva „energentom 21. veka“ jer osim ekoloških prednosti poseduje i izražene tehničke i ekonomske pogodnosti u odnosu na druga konvencionalna goriva. Sa tehničkog i ekonomskog aspekta, prednosti korišćenja gasa su niski investicioni troškovi i cena, visok stepen iskorišćenja, pouzdanost i fleksibilnost upotrebe, lakše i bezbednije skladištenje u odnosu na druga fosilna goriva. Ovaj energent raspoloživ je tokom cele godine, a njegov kvalitet je standardizovan i garantovan. Iako su dokazane svetske rezerve obilne, racionalno upravljanje i korišćenje prirodnog gasa je od izuzetne važnosti uzimajući u obzir činjenicu da se radi o neobnovljivom izvoru energije. Kako se radi o zapaljivoj i eksplozivnoj smeši, pažljivo rukovanje i odorizacija gasa predstavlja preduslov za bezbedan rad u svim postrojenjima koja koriste ovaj tip goriva u svojim operativnim procesima. Kao nedostatak može se i izdvojiti i doprinos gasa povećanju efekta staklene bašte. Cilj ovog rada jeste pronalaženje optimalnog oblika trase primarne distributivne mreže gasovoda u opštini Kučevo, definisanje lokacija i položaja GMRS i MRS, usvajanje prateće opreme za GMRS, dimenzionisanje cevi zasnovanim na normativima i pravilnicima za distributivne mreže srednjeg i visokog pritiska, uz postizanje bezbednosti i sigurnosti u snabdevanju kako sadašnjih, tako i budućih potrošača.

The field of application of natural gas is very wide. As an energy source, it can be used for energy production in power plants, heating plants and cogeneration plants or for meeting various heat needs in industry and mass consumption. Gas can also be used as a raw material in the chemical and petrochemical industries, and during the last decades it has also been used in traffic as a propellant in SUS engines. 2 • 35 rd INTERNATIONAL CONGRESS ON PROCESS INDUSTRY From an environmental point of view, natural gas is the most acceptable source of energy compared to other fossil fuels. Due to its chemical composition, the combustion of natural gas emits significantly less carbon dioxide per unit of heat produced, there is no ash and no particulate emissions, and sulfur dioxide emissions are negligible. Natural gas is often called the "fuel of the 21st century" because, in addition to environmental advantages, it also has pronounced technical and economic advantages over other conventional fuels. From a technical and economic point of view, the advantages of using gas are low investment costs and price, high degree of utilization, reliability and flexibility of use, easier and safer storage compared to other fossil fuels. This fuel is available throughout the year, and its quality is standardized and guaranteed. Although the world's proven reserves are abundant, the rational management and use of natural gas is extremely important, given the fact that it is a non-renewable energy source. As it is a flammable and explosive mixture, careful handling and odorization of gas is a prerequisite for safe operation in all plants that use this type of fuel in their operational processes. The contribution of gas to increasing the greenhouse effect can also be singled out as a disadvantage. The aim of this paper is to find the optimal shape of the route of the primary distribution network of gas pipelines in the municipality of Kučevo, defining locations and positions of MMRS and MRS, adoption of supporting equipment for MMRS, pipe sizing based on norms and regulations for medium and high-pressure distribution networks. in supplying both current and future consumers.
