چکیده

The heat generated in a high-temperature gas-cooled reactor can be used to drive the iodine-sulfur cycle produce hydrogen. However, sulfuric acid decomposition step requires sophisticated decomposer increase rate. of mainly occurs catalytic zone, and optimization its structure is very important for increasing This study focuses on structural design zone unit. with double inner tubes designed analyze influence tube transfer area volume annulus region species transport model predict proportion products followed by analysis key factors affecting rate domain. results reveal that new attains temperature requirements increases fluid velocity tube. turn promotes effect. negatively correlated flow Nonetheless, which have same total as single has better effect than It up 6.1% while does 1.7%. maintained at relatively high level when inlet current about 0.2 m/s. provides reference engineering based exchange volume.

The decomposition of methionine in sulfuric acid.

The classical procedure for the preparation of homocystine consists of boiling a solution of methionine in 50 per cent sulfuric acid followed by neutralization (1). Although the yields of homocystine account for only 25 to 45 per cent of the methionine, the nature of the reaction has received little attention since originally published by Butz and du Vigneaud (1). These authors noted the format...

LQ Control Of Heat Exchanger - Design And Simulation

Heat exchangers are devices whose primary responsibility is the transfer (exchange) of heat, typically from one fluid to another. However, they are not only used in heating applications, such as space heaters, but are also used in cooling applications, such as refrigerators and air conditioners. Heat exchange processes often contain time-delay. This paper deals with design of universal and robu...
