Abstract

Posljednjih godina značajno se povećavaju kapaciteti postrojenja za ukapljivanje i uplinjavanje prirodnog plina. Odabir procesa ukapljivanja je jedan od ključnih elemenata koji se razmatra pri izgradnji postrojenja za ukapljivanje prirodnog plina. Trenutno se za ukapljivanje prirodnog plina koristi nekoliko procesa koji se međusobno razlikuju brojem rashladnih ciklusa i odabirom rashladnog sredstva. Termodinamička učinkovitost i cijena opreme su važni elementi koji se uzimaju pri odabiru ciklusa ukapljivanja. Danas je dominantna tehnologija ukapljivanja prirodnog plina ukapljivanje korištenjem C3 MR procesa. Na globalnom tržištu sve konkurentniji postaju su Philipsov optimizirani kaskadni proces, Linde/Statoil-ov kaskadni s miješanim fluidima, Shell-ov proces s dva miješana rashladna sredstva, APCI- ov APX proces i drugi procesi. Također poseban izazov za budućnost tehnologije ukapljivanja je razvoj odobalnih postrojenja za ukapljivanje i odabir procesa ukapljivanja na tim postrojenjima. Tada su važni kriteriji odabira sigurnost i jednostavnost, te se prednost daje ekspandirajućim procesima ukapljivanja prirodnog plina.

Abstract: In a last few years, the capacitys of liquefaction and regasification plants of natural gas are signifiticantly increasing. Selection of liquefaction is one of the key elements to be considered when building a plant for liquefying of natural gas are signifiticantly increasing. Currently, for natural gas liquefaction process we use several differing number of cooling cycles andseveral different refrigerants. Thermodynamic efficiency and cost of equipment are important elements to be taken when choosing the liquefaction cycleprocess. Today, the dominant technology of liquefaction of natural gas is liquefaction using C3 MR process. In the global market, Philips Optimized cascade process, Linde/Statoil's Cascade with mixed fluids, Shell's process with two mixed refrigerants, APCI's APX process and other process are becoming more competetive. Also a special challenge for the future of liquefaction technology is development of offshore liquefaction plants and the selection of liquefaction at these plants. The important criteria is selecting security and simplicity, and preference is given to expander technology of liquefaction.
