Preliminary note The paper presents an analysis of annual variations of temperature and the corresponding saturation pressure of saturated liquid propane in a mounded cylindrical tank used for liquefied petroleum gas (LPG) storage. A mathematical model has been established based on a finite volume method. Boundary and initial conditions have been assumed for the Croatian climate. Simulations ha...

The production of engines using turbocharged stratified injection technology has increased rapidly in recent years. In addition, the use liquefied petroleum gas, which is an environmental and economical fuel, increasing vehicles. While gas cannot be used before, kits have become applicable to these types with development technology. Turbocharged provide first ignition liquid fuel engines. There...

Abstract—Packed columns of liquefied petroleum gas (LPG) consists of separating the liquid mixture of propane and butane to pure gas components by the distillation phenomenon. The flow of the gas and liquid inside the columns is operated by two ways: The co-current and the counter current operation. Heat, mass and species transfer between phases represent the most important factors that influen...

The Fischer-Tropsch synthesis (FTS) is a heterogeneously catalyzed surface polymerization reaction with wide spectrum of hydrocarbons as products, following the Anderson-Schulz-Flory distribution. Subsequent cracking unwanted long-chain products can increase desired product fraction shorter (HCs). In this work, Co/Mn-catalyzed FTS additional by Pt/H-ZSM-5 zeolite was investigated to selectivity...

 Taxation is one of the significant phenomena in any economy as it not only generates revenues for existing government, but also serves as a fiscal tool and stabilization policy. One of the main types of taxation is the petroleum tax which accounts for more than 30% of revenue for developed countries and more than 85% for developing economies. This work focuses on petroleum producing giants in ...
