Mar 01, 2015· Block Flow Plant Diagram This model of flow diagram is used to explain the general material flows throughout an entire plant They will be generalized to certain plant sectors or stag These documents would help orient workers to the products and important operation zones of a chemical facility (Peters and Timmerhaus, 2003)
(chlorosulfuric acid), water or sulfuric acid (sulfuric acid or oleum) and dry air (air/SO3 film sulfonation) Control of the ratio of SO3 to organic raw material is vital to achieving the desired product quality with use of any of the agents Additionally, these processes require heat removal to maintain product quality
A flow scheme for this part of the process looks like this: The reasons for all these conditions will be explored in detail further down the page Converting the sulphur trioxide into sulphuric ac This can't be done by simply adding water to the sulphur trioxide - the reaction is so uncontrollable that it creates a fog of sulphuric ac
