Abstract

In this paper gasification performance of Mazut of Iran’s refineries based on Gibbs free energy minimization is studied. A parametric study was performed in order to investigate the effects of different agents (oxygen, air, and steam), equivalence ratio and gasifier pressure on syngas composition, gasification temperature, high heating value, cold gas efficiency, and exergy efficiency. The results of oxygen-gasification show that Mazut can be employed in the integrated gasification power generation systems and provides constant and appropriate exergy efficiency contents. Additionally, mazut gasification with air-steam or oxygen-steam is more efficient in order to produce syngas for chemical applications. The present study assesses syngas compositions and gasification performance characteristics for different operating conditions.

重油的气化：不同气化剂能量和火用分析的参数研究

摘要

本文研究了基于吉布斯自由能最小化技术的伊朗炼油厂马祖特的气化性能。为了研究不同试剂（氧气，空气和蒸汽），当量比和气化炉压力对合成气组成，气化温度，高热值，冷气效率和火用效率的影响，进行了参数研究。氧气气化的结果表明，Mazut可用于集成气化发电系统，并提供恒定和适当的火用效率内容。另外，用空气蒸汽或氧气蒸汽进行马祖特气化更有效，以生产用于化学应用的合成气。本研究评估了不同操作条件下的合成气组成和气化性能特征。
