PETROX – PETROBRAS Technology in Process Simulation

Correlation for predicting the molecular weight of Brazilian petroleum residues and cuts: An application for the simulation of a molecular distillation process

“…To perform the initial calculations, a complete identification of the constitutive compounds of the residues was necessary. Thus, the PETROX simulator was used to do a simulation of the fractionation of the whole crude oils (Niederberger et al, 2005). From this simulation the total number of components and pseudocomponents that evaporated during the conventional distillation of petroleum was predicted.…”

Cubic Plus Association Equation of State for Flow Assurance Projects

“…In this context, the development of an in-house process simulator has strategic advantages for the company, and these tools become part of the technology development. Therefore, this work aims to present results of calculations carried out using the Petrobras' Process SimulatorPETROX 16 after the inclusion of the CPA EoS, as one of the thermodynamic models available in the simulator. Although we present an implementation using the Petrobras' Process Simulator, the results and experience presented here are useful for other simulators and other research groups.…”

Modeling Water Saturation Points in Natural Gas Streams Containing CO2 and H2S—Comparisons with Different Equations of State

“…(PETROX) Using a program developed by the Federal University of Rio de Janeiro in 1985, a group of engineers started the development of PETROX in 1989, and in 1993 its first version was made available, after the implementation of its first module, the distillation column. 9 (Figure 1). The graphic interface makes the communication with the user easier, and it is this part of the code that reads input data and carries them over to the software core.…”

Later on other modules were implemented into PETROX, forming the software as it is today.…”

“…Therefore, this work aims to present results of calculations carried out with Peng−Robinson (PR) 5 and Soave−Redlich−Kwong (SRK); 6 GERG-modified Peng− Robinson (PR-ISO-04), 7 and Cubic Plus Association (CPA) 8 EoS. Moreover, all phase equilibrium calculations were performed using Petrobras' Process SimulatorPETROX, 9 making these results useful for design and real time process analysis.…”
