Process simulators are becoming basic tools in chemical engineering programs. Senior-level design projects typically involve the use of either a commercial simulator or an academic simulator such as ASPENPLUS, ChemCAD, ChemShare, FLOWTRAN, HYSYS, and ProII w/PROVISION. Many design textbooks now include exercises specifically prepared for a particular simulator. For example, the text by Seider, ...

and Scope of the Work The present work is part of a research project that is currently in progress at Tarragona with the main objective to develop an open and distributed architecture capable of supporting applications of collaborative intelligent techniques to control chemical processing plants. In this paper new ways to integrate external components with the HYSYS Process Simulator are explor...

Optimization of the whole plant instead of important individual units is essential for maximizing savings and operational efficiency. Often, there are conflicting objectives for optimizing industrial processes. Many previous studies on multi-objective optimization involved a few critical units (and not complete plants) using models and simulation programs specifically developed for the respecti...

This paper presents a study on the data-driven modelling and optimisation of a crude oil hydrotreating process using bootstrap aggregated neural networks. Hydrotreating (HDT) is a chemical process that can be widely used in crude oil refineries to remove undesirable impurities like sulphur, nitrogen, oxygen, metal and aromatic compounds. In order to enhance the operation efficiency of HDT proce...

Heightened concerns over the amount of carbon emitted from coal-related processes are generating shifts to the application of biomass. In co-gasification, where coal is gasified along with biomass, the biomass may be fed together with coal (cofeeding) or an independent biomass gasifier needs to be integrated with the coal gasifier. The main aim of this work is to evaluate the biomass introducti...

Motivation The application of a genomics assay to samples from a cohort is a frequently applied experimental design in cancer genomics studies. The collection and analysis of cancer sequencing data in the clinical setting is an elaborate process that may involve consenting patients, obtaining possibly-multiple DNA samples, sequencing and analysis. Many of these steps are manual. At any stage mi...

In this time of energy crises, low production rate against the increasing demand of oil and gas production regularly hampers both domestic and industrial operations. In addition, safety hazards arising from explosion and increase in the cost of production due to pumping cavitation has pose a great challenge on offshore Floating Production Storage and Off-loading (FPSO) terminals. In view of the...

Natural gas is the most popular fossil fuel in the current era and future as well. Natural gas is existed in underground reservoirs so it may contain many of non-hydrocarbon components for instance, hydrogen sulfide, nitrogen and water vapor. These impurities are undesirable compounds and cause several technical problems for example, corrosion and environment pollution. Therefore, these impurit...

A Hysys model representing the steady state behaviour of a Haber-Bosch ammonia plant was developed based on a dynamic model and plant data from Norwegian fertiliser company Yara International ASA. The plant model was optimised using matlabs fmincon function with an interior-point method for economical optimisation with the aim to study the performance of different strategies. The Haber-Bosch am...
