Harm and control of acidity and ash in liquid sulfur Chen Wenhai, Yao Guangsheng (Sinopec Shijiazhuang Refining and Chemical Branch, Shijiazhuang, Hebei 050032) Abstract: The quality indicators of sulfur and the melting and filtration process of sulfur are introduced. The harm of liquid sulfur acidity and ash to production is discussed, as well as the control measures taken in production. keywords: liquid sulfur ； acidity ； Ash content ； harm ； control
I hope the poster can introduce the relevant information of the converter, such as material, structure, support method, catalyst loading, etc.
1 The converter is made of 304 stainless steel, with columns supporting partitions and grilles, and sliding legs at the bottom.； 2 The catalyst loading capacity is generally 200L/(td).
The converter drawings shared on the 7th floor cannot be downloaded because the permissions are not enough. In addition, I would like to ask for advice. The temperature of the high-temperature section of the converter is generally around 600 degrees. How to prevent material sensitization problems using 304? Thank you.
Operation adjustment of the converter of the 200 kt/a sulfur acid plant Jiang Hao (Phosphate Fertilizer Plant of Sinopec Nanjing Chemical Industry Co., Ltd., Nanjing, Jiangsu 210048) Abstract: The conversion rate is the main control parameter for the production of the sulfur acid production unit and one of the important indicators to measure the economy and advancement of the unit's production. This paper introduces the operation of the converter of the 200 kt/a sulfur acid production unit, the conversion rate of each section of the converter, the total conversion rate and the section pressure drop. By analyzing the test results, the main factors affecting the conversion rate of the converter are explained, and measures to improve the conversion rate are proposed. keywords: Sulfuric acid production + sulfur ； conversion rate ； catalyst ； Summary of "Sulfur and Phosphorus Design and Powder Engineering" Issue 2, 2006
Design of stainless steel converter in sulfuric acid plant Yu Qun (Nanhua Group Design Institute, Nanjing, Jiangsu) [Abstract] Introduced the design characteristics of the first domestically designed and manufactured converter, the stainless steel converter for sulfuric acid production. The main material of the converter is 304H. The shell wall of the catalyst bed section is lined with aluminum silicate fiber bricks. The upper surface of each partition is laid with aluminum silicate fiber bricks, and a thin sealing ring is used. The lower part adopts a reinforced rib structure, and the bottom adopts a sliding bearing. [Keyword] Converter ； design ； Stainless steel
