This work presents the results from dynamic modeling and control of an azeotropic distillation system. The model was validated with experimental data from a packed distillation unit. The physically-based process dynamic model, developed in HYSYS, was linked online with the control software used in the process. Model parameters were modified online using a feedback configuration to eliminate the...

A dynamic model developed in the HYSYS process simulator was validated using experimental data obtained from a pilot scale cyclohexane / n-heptane distillation. The resulting model was linked to the pilot unit’s DeltaV (Emerson Process Management) process control software. This link allowed non-measured parameter estimation to occur in parallel with the operation and control of the pilot plant ...

It is well known that the capacity of crude distillation units in any refinery reflect itself, and why because we consider these first stage all other such as vacuum distillation, hydrotreating, reforming, catalytic cracking, others depend on them. So devoted our effort to keep work with high performance efficiency.
 The purpose this develop Daura oil refinery, rise their level detect were...

This paper presents the multi-objective optimization of a crude oil hydrotreating (HDT) process with atmospheric distillation unit using data-driven models based on bootstrap aggregated neural networks. Hydrotreating whole has economic benefit compared to conventional individual products. In order overcome difficulty in developing accurate mechanistic and computational burden utilizing such opt...

advanced exergy analysis is a tool to split the exergy destruction of the system to achieve a better perspective about the potentials of a system for improvements. in addition, the component interactions and their exergy destruction dependency with the other equipment are investigated through the advanced exergy analysis. for this purpose, it divides the exergy destruction calculated by convent...

The HP scrubber is an equipment used to separate liquid from gas in the oil and industry. low level vessel one of abnormal conditions scrubber, a blowby event will happen because level. So, controller indicator required prevent system damage workplace accidents. alarm response time calculated order avoid accident. To determine for dynamic process simulation method can be using Aspen HYSYS versi...

The article shows examples of the use Aspen Hysys software for optimization AVT-3 and AT-2 crude oil distillation units at Atyrau Oil Refinery. was implemented Refinery first time.Calculations were carried out to optimize refinery with construction a model in Hysys. As result calculations, possibility improving efficiency individual parts revealed, pilot runs on confirm. During run unit, restri...
