Abstract Gilsonite has a wide variety of applications in the industry, including manufacture electrodes, paints and resins, as well production asphalt roof-waterproofing material. ash is determining parameter for its application some industries (e.g., gilsonite with content < 5% used an additive drilling fluids, resins). Due to shortage high grade (low ash) reserves, aim this study develop p...

In this work a systematic framework is introduced to synthesize the optimal separation process of azeotropic mixtures. The proposed framework, which can handle an arbitrary number of components, consists of two main steps: a system analysis and a state-space superstructure algorithm. The system analysis is composed of some equation-oriented algorithms to supply basic information for the superst...

A methodology for computer aided design and analysis of separation processes involving electrolyte systems is presented. The methodology consists of three main parts. The thermodynamic part “creates” the problem specific property model package, which is a collection of pure component and mixture property models. The design and analysis part generates process (flowsheet) alternatives, evaluates/...

This paper studies the synthesis and the design of methanol recovery system for TAME reactive distillation process using extraction column with water as a solvent. The design of the extraction column system has not been studied in the literature. The effect of operating conditions such as solvent flowrate, extraction column temperature, and number of equilibrium trays are studied. It is found t...

The mathematical model developed in this paper deals with simultaneous synthesis of the integrated separation network, where both mass separating agents (MSAs) and energy separating agents (ESAs) are taken into account. The proposed model formulation is believed to be superior to the available ones. Traditionally, the tasks of optimizing ESA-based and MSA-based processes were either performed i...

Porcelain tile manufacturing is an energy-intensive industry that in dire need of increasing productivity, minimizing costs, and reducing CO2 emissions, while keeping the product quality intact to remain competitive today’s environment. In this contribution, alternative processing parameters for porcelain production sequence were proposed based on simulation-based process optimization. Flowshee...

In this work, we present a novel framework that comprises four stages of process modeling and multiobjective decision-makings considering monetary and non-monetary aspects. Four stages in early design phases are considered and characterized by the available information for process modeling and assessment. Appropriate modeling methods, and evaluation indicators for economy, life-cycle environmen...

A new framework for the implementation of reliability centered maintenance (RCM) in the initial design phases of industrial chemical processes was developed and implemented. Fuzzy reasoning algorithms were designed to evaluate and assess the likelihood of equipment failure mode precipitation and aggravation. Furthermore, an approximate reasoning scheme which considers local, product, and adjace...
