Computer Simulation of Ammonia Cold Shot Converter

A mathematical model is developed and tested with plant data for the ammonia cold shot converter of Razi Petrochemical Complex. The model is based on a material and energy balance in a differential element of beds and is subjected to the assumptions of uniform distribution of temperature and composition through a general cross section and negligible mass and heat transfer in axial direction. Th...

Mitigation of Harmonics and Inter- harmonics in VSI-Fed Adjustable Speed Drives

Abstract – The components of harmonics are integral multiple of the fundamental component and the components of inter-harmonics are are non integral multiple of the fundamental component. AC-DC-AC conversion systems used in variable speed drive are sources of inter-harmonics. There are several reasons for inter-harmonic generation in variable speed drives. In this paper, the generation of inter...
