Reactor mini-pilot

In this paper, a heat flow calorimeter designed for the investigation of industrial organic reactions is presented. This instrument is extensively used for the elucidation of reaction kinetics and for the assessment of thermal hazards. It also permits the determination of heats of reaction, specific heats and heat transfer coefficients, and due to its accurate controls, it is an ideal "mini-pilot-reactor". 

Used as a mini-pilot-reactor, the bench-scale-calorimeter in many cases provides data which permits a direct scale-up to plant scale, when conventional means would neccessite a pilot stage. Thus, it is a powerful tool for process development, drastically reducing cost and time required. 

As pointed out in Section 1, research and development work on the catalytic OCM reaction is mainly carried out in the "cofeed" mode although a significant amount of development work has been also accomplished in the "redox" mode by ARCO. It appears, however, that work at ARCO has been terminated. For both types of processing catalytic fixed-bed and fluidized-bed reactors have been applied in bench-scale and mini-pilot-plant studies.

OS 68] [R 19] [P 50] A numbering-up of five mini mixers, tested at the pilot stage, was used [134]. Automation of the entire process was required liquid-flow splitting to the single reactors was ... by no means trivial... [134]. The capacity of one mini reactor was 30 ml s , i.e. 1081 h . The complete setup hence should be operated close to 5001 h . The micro-reactor plant was operated at intervals as the preceding step was carried out batchwise. The operation of the micro-reactor plant started in August 1998 after a period of only about 1.5 years for development. 

UOP then carried out pilot-scale tests at still higher pressures in a fully automated explosion cell to reproduce vendor work and to study conditions and kinetics. Design was based on direct hydrogen peroxide synthesis using a mini-trickle bed reactor with a micro mixer.
