Flare Load Reduction by Implementing HIPS in Assaluyeh gas Refinery
, M.Sc. Thesis Sharif University of Technology ; Sattari, Sorna (Supervisor)
Abstract
The HIPS is a safety integrity system that is designed to provide overpressure protection that is at least equivalent in reliability to a mechanical relief device. In this study, the performance evaluation of HIPS in Assaluyeh gas Refiner is studied.In the first stage, over pressure analysis is compiled using dynamic simulation and API RP 520 and the recommended HPPS design procedure is presented. Also, The High Integrity Protection Systems (HIPS) further reduced the relief load and even eliminated the relief from the stabilizer tower for the scenarios tested.In this project, following a detailed study of the commissioning process and its criticalities, Hazop is selected as the most suitable...
Physical and hydraulic properties of a new spring packing
, Article CHISA 2006 - 17th International Congress of Chemical and Process Engineering, Prague, 27 August 2006 through 31 August 2006 ; 2006 ; 8086059456 (ISBN); 9788086059457 (ISBN) ; Yazdani, F ; Farhadi, F ; Deldari, H ; Sharif University of Technology

Abstract
Physical and hydraulic properties of new stainless steel spring packing are introduced. The measured hydraulic properties are: dry and wetted packed bed pressure drop, loading and flooding points and the liquid holdups. The appropriate coefficients for predicting the mentioned hydraulic properties from different correlations are also reported. Hydraulic properties for this packing are compared with available packings. In spite of small size, the dry and wetted packed bed pressure drops of spring packing are less than similar Raschig and Protruded rings. The total liquid holdup of this packing is greater than other commercial packings. The big total liquid holdup and physical surface area are...
Developing a Hybrid Technology Evaluation Model for Minimization of the Cost of the Dynamic Effects of Changes and Resource Consumption on Ecosystem Sustainability
, Ph.D. Dissertation Sharif University of Technology ; Saboohi, Yadollah (Supervisor)
Abstract
Rapid population growth and increasing and rapid consumption of natural resources in the ecosystem leads to the destruction of resources and thus increases the entropy in the earth, and this increase in entropy in the ecosystem changes the environment and has adverse effects on it. As all components in nature interact with each other by action and reaction, therefore, any change in the environment must be adjusted by other sectors and approached a reversible process to enable sustainable ecosystem changes. On the other hand, there is evidence that the world's physical capacity is inadequate to meet the requirements of sustainable development. The reason for this fact is that the ecological...
The tolerance level of the ecosystem as a limited constrain in the development planning

Abstract
There are several methods for assessing ecosystem tolerance level, each method is defined according to the target of the ecosystem development. This paper seeks a way to plan for the development of the existing ecosystems modified for human activities. For this purpose, two methods have been applied to assess the effects of local development on the local ecosystem tailored to the different demands. Thus, after gathering data in a coastal region all technologies being capable to be applied in this region regarding ecotourism development (population growth) were determined. Via different indicators, the quality of the ecosystem was evaluated. The Ecosystem Quality Index (EQI) and Technique for...
Multi objective planning for sustainable retrofit of educational buildings
, Article Journal of Building Engineering ; Volume 24 , 2019 ; 23527102 (ISSN) ; Aramoun, F ; Bararzadeh, M ; Avami, A ; Sharif University of Technology

Abstract
The sustainable retrofit options may significantly improve the energy consumption and the environmental impacts of the existing buildings. This paper presents a multi objective optimization framework to reach the minimum economic costs and Global Warming Potential (GWP) impact of existing buildings. New energy-efficient technologies for the supply side of the energy system are considered which may minimize life cycle environmental impacts of buildings. Two educational buildings in the campus of Sharif University of Technology are studied. The results show that utilizing reciprocating engine and exhaust-fired absorption chiller reduce the GWP to 133 tons (17.79% of reduction) and 190 tones...
Building circularity as a measure of sustainability in the old and modern architecture: A case study of architecture development in the hot and dry climate
, Article Energy and Buildings ; Volume 275 , 2022 ; 03787788 (ISSN) ; Golabchi, M ; Bararzadeh Ledari, M ; Sharif University of Technology

Abstract
Nowadays, the construction industry has turned to the consumption of large amounts of natural resources in line with global population growth, which has led to the shortage of resources, and consequently increases in the construction debris; therefore, the present article has studied the positive and negative points of the architectural development process. The results have indicated that being compared to the former architecture; the development of architecture has reduced energy consumption by 78%. Hence, the scarcity of virgin resources and consequently the increase of environmental effects such as Global Warming Potential (GWP) have been measured based on the Life Cycle Assessment (LCA)....
Greening steel industry by hydrogen: Lessons learned for the developing world

Abstract
Whole-of-economy greenhouse gas emissions reduction is one of the most important targets of transitioning to sustainable energy systems. With 7% of global emissions, the steel industry is one of the most carbon-intensive industries. Approximately two-thirds of annual steel production is attributed to the conventional blast furnace (BF)/converter route with high carbon emissions. Many countries in the world have developed large-scale laboratory pilots in line with steel production processes with green hydrogen or syngas. In this study, the experienced strategies of green, gray, and blue steel generation in the world are studied. Accordingly, the technology development approach of different...
BIM with blockchain for decentralised circular construction supply chain

Abstract
Blockchain and smart contracts are measures to speed up the diffusion of circular economy into construction processes. Nevertheless, integrated solutions that cover all the aspects of circular supply chain including network structure, business processes, and products are still missing. This chapter addresses this gap, through offering a workable solution to address the disconnected nature of blockchain adoption across construction procedures. Informed by the overall approach of design science research (DSR), the solution is created following the five-staged procedure of DSR: (1) problem identification, (2) treatment suggestion, (3) treatment design, (4) evaluation and (5) conclusion....
