[ 1 ] - Superstructure of Cogeneration of Power, Heating, Cooling and Liquid Fuels Using Gasification of Feedstock with Primary Material of Coal for Employing in LNG Process
Using absorption refrigeration cycles instead of vapor compression refrigeration cycles can drastically decrease energy consumption. In these systems, high level of energy consumption is reduced due to the partially elimination of vapor compression refrigeration systems. On the other hand, utilization of waste heat of the plant, which is a very good opportunity for energy saving, is possible. ...
[ 2 ] - Exergoeconomic Evaluation of an Integrated Nitrogen Rejection Unit with LNG and NGL Co-Production Processes Based on the MFC and Absorbtion Refrigeration Systems
Natural gas is often associated with nitrogen and heavy compounds. The Heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. Therefore, heavy components separation can be a necessity and produce useful products. Virtually, all natural gases are containing nitrogen that would lower the heating value of natural ...
[ 3 ] - Advanced Exergy Evaluation of an Integrated Separation Process with Optimized Refrigeration System
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...
[ 4 ] - Thermodynamic and Economic Optimization of a Refrigeration Cycle for Separation Units in the Petrochemical Plants Using Pinch Technology and Exergy Syntheses Analysis
Exergy and thermoeconomic analyses are herein employed to evaluate the proposed refrigeration cycle of Tabriz olefin plant. The exergetic and exergoeconomic variables of all equipment and streams are calculated. Thermoeconomic model is developed according to the total revenue requirement (TRR) method. The results indicate that the rational efficiencies of the Heat Exchanger E-104 and compressor...
[ 5 ] - The Mathematical Method and Thermodynamic Approaches to Design Multi-Component Refrigeration used in Cryogenic Process Part II: Optimal Arrangement
A refrigeration cycle is a chain of various pieces of equipment including compressors, condensers, evaporators, and expansion devices each of which takes on a particular thermodynamic process duty in the cycle that eventually results in the production of the required refrigeration. The results of optimized mixed refrigerant cycles (MRCs) in Part I show that the configuration of MRC is an eff...
[ 6 ] - Mathematical Method and Thermodynamic Approaches to Design Multi-Component Refrigeration Used in Cryogenic Process Part I: Optimal Operating Conditions
Abstract: Minimizing the work consumed in refrigeration system is the most effective measure to reduce the cost of products in sub-ambient chemical processes. The introduction of mixed working fluids into refrigeration system in place of pure working fluids is a recent advancement applied in the field. Due to the lack of systematic design method for Mixed Refrigerant Cycle (MRC), conventional a...
[ 7 ] - Optimization of Distillation Column Operation by Simulated Annealing
Abstract: In this paper, an exergy analysis approach is proposed for optimal design of distillation column by using simulated annealing algorithm. First, the simulation of a distillation column was performed by using the shortcut results and irreversibility in each tray was obtained. The area beneath the exergy loss profile was used as Irreversibility Index in the whole column. Then, First Opti...
[ 8 ] - The Design of the Best Heat Integrated Separation Systems Using Harmony Search Algorithm
The synthesis of heat integrated multi-component distillation systems is complex due to its huge search space for structural combination and optimization computation. To provide a systematic approach and tools for the synthesis design of distillation systems, a new method for modeling heat integrated columns is presented, and the operating cost objective function is minimized by improved harmon...
[ 9 ] - تحلیل اقتصادی - فنی کاهش مصرف آب و انتشار گاز دی‌اکسید کربن با بهره‌گیری از انرژیهای تجدیدپذیر برای تولید الکتریسیته (مطالعۀ موردی: نیروگاه بخاری بعثت تهران)
هدف اصلی پژوهش حاضر، معرفی نوعی سیستم هیبریدی تجدیدپذیر جایگزین، با نیروگاه بخاری بعثت تهران است. از آنجا که کمبود آب و انتشار گازهای گلخانهای، از مهم‌ترین دغدغههای زیست‌محیطی است، نیروگاههای فسیلی به دلیل میزان مصرف آب و نیز مقدار انتشار دی‌اکسید کربن، اهمیت درخور توجهی دارند. در مطالعۀ حاضر، ابتدا با معرفی نیروگاه بخاری بعثت تهران، انواع هزینههای مربوط به این نیروگاه از جمله هزینۀ مصرف آب...
