| Abstract: | This paper gave an introduction to the structure of the shell-and-tube reactor for methanol synthesis application. It brings forward the concept of cushion gas that appears during the operation of such reactors.It tells the causes of the cushion gas and also the harm it does during operation.It pointed out that the cushion gas is the main fact that causes overheat to the upper tubesheet and the upper heat exchange tubes,and that makes them ineffective.The paper gave examples to show the impact of the improp... |
