Abstract

The Claus process has been known and used in the industry for over 100 years. It involves thermal oxidation of hydrogen sulfide and its reaction with sulfur dioxide to form sulfur and water vapor. This process is equilibrium-limited and usually achieves efficiencies in the range of 94-97%, which have been regarded as acceptable in the past years. First bed operates at the temperature of 573 K, second and third beds operate at 523K and 473K. Outlet of each bed enters the condenser. Operating temperature of each condenser is about 413K which sulfur condenses in them. In this study catalytic bed process of sulfur recovery unit has been mathematically modeled and by MATLAB software simulated, and then output conditions of compounds has been calculated. Keywords: Sulfur recovery; Claus process; catalytic beds; modeling; simulation DOI = 10.3329/cerb.v14i2.5595 Chemical Engineering Research Bulletin 14 (2010) 110-114
克劳斯工艺催化床中凝聚硫的建模与模拟:快速估算
克劳斯工艺已经在该行业中使用了100多年。它涉及硫化氢的热氧化及其与二氧化硫的反应,形成硫和水蒸气。这个过程是平衡有限的,通常在94-97%的范围内实现效率,这在过去的几年里被认为是可以接受的。第一床的工作温度为573 K,第二床和第三床的工作温度分别为523K和473K。每层的出口进入冷凝器。每个冷凝器的工作温度约为413K,硫在其中凝结。本文对硫回收装置的催化床过程进行了数学建模,并利用MATLAB软件进行了仿真,计算了化合物的输出条件。关键词:硫回收;老人的过程;催化床;建模;DOI = 10.3329/cerb.v14i2.5595化学工程研究通报14 (2010)110-114
