Reactor design mechanical features

Adami, I. Design criteria, mechanical features, advantage and performance of multitube falling film sulphonation reactor. Tenside Surfact. Det. 41(5), 240-245, 2004. 

A substantially new and critical feature in bottom-entering agitators is the sealing of the shaft double mechanical seals are used here. On modem designs, they are provided with additional standstill seals for emergencies. The standstill seal allows the mechanical seal to be replaced while the reactor is full and under pressure. In a number of polymerizations, particularly in vinyl-chloride polymerization, the rotating elements must be protected by additional water flushing (4) other-... 

Role of Reactor and Process Design Optimization of catalytic performances, in terms of reactant conversion, yield, productivity and selectivity to the desired product, is not only related to a thorough knowledge of the nature of the catalyst and the interactions between reacting components and surface active phases, the reaction mechanism, thermodynamics and kinetics but also to the development and use of a suitable reactor configuration, where all the above-mentioned features can be successfully exploited.
