Abstract
Vodikova mreža može se opisati kao sustav procesa u rafineriji koji međusobno djeluju i komuniciraju preko distribucije vodika. Ti procesi dijele se na proizvođače, potrošače, te jedinice za pročišćavanje vodika. Dobro upravljanje vodikom znači i maksimalno iskorištenje vodika, pri čemu važnu ulogu ima i kvalitetna bilanca tokova tvari u kojima se nalazi vodik. Pristup integraciji sustava vodika može se podijeliti na dvije kategorije: pinch analiza i metode matematičkog programiranja koje se temelje na optimizaciji superstrukture. Pinch analiza je grafička metoda koja daje jasan vizualan prikaz korištenja suviška vodika. Njena najveća prednost je jednostavnost, dok prednost metode matematičkog programiranja je mogućnost pregleda niza ograničenja i varijabli. To se prvenstveno odnosi na ograničenje tlaka, kapaciteta, te operativne i investicijske troškove nove opreme i cjevovoda. Neke od metoda matematičkog programiranja su: metoda linearnog programiranja (LP), mješovitog cjelobrojnog linearnog programiranja (MILP), nelinearnog programiranja (NLP) ili mješovitog cjelobrojnog nelinearnog programiranja (MINLP).
Abstract (english)
A hydrogen network can be described as refinery process systems that interact and communicate with each other through hydrogen distribution. These processes can be categorized as hydrogen producers, hydrogen consumers, and hydrogen purification units. Effective hydrogen management means maximum utilization of hydrogen, whereby mass balance of streams containing hydrogen plays important role in solving hydrogen network optimization problem. Hydrogen integration methods can be divided into two categories: pinch analysis and mathematical programming approaches based on superstructure optimization.Pinch analysis is a graphical method that provides a clear insight into the utilization of excess hydrogen. Its greatest advantage is simplicity, while the advantage of the mathematical programming method is the possibility of considering a large number of constraints and variables. This is related primarily to the restrictions of pressure, unit capacity, operating, and investment costs of new equipment and pipelines.Some of the methods of mathematical programming are: linear programming (LP), mixed integer linear programming (MILP), non-linear programming (NLP) and mixed integer non-linear programming (MINLP).
