This thesis aims to computationally simulate the electronic transducer for a parallel electrical capacitance tomography, can generate a voltage level used for image reconstruction of the adsorption phenomenon occurred in the adsorptive bed. This simulation was performed using a computer program like SPICE (Simulation Program with Integrated Circuit Emphasis) for the purpose of defining the parameters for its construction, dedicated to the application of the adsorptive bed bench in a glass case studies of the adsorptive process. This technique uses capacitive sensors coupled to an electronic transducer that will generate a voltage signal associated with the distribution of dielectric permittivity of the medium. The simulation is developed to simulate the main circuit, a differentiator, fitted with high frequency OPA 2690. The simulated model is a simple circuit with a transmitter and a receiver. The results show the technical feasibility of the project being proposed for future work to implement a prototype of the electronic transducer of electrical capacitance tomography applied to the study of the adsorption process.
