Convective diffusion without difusion?

I have a model where the Peclet number is of the order of 100,000. Hence, in the convective diffusion equation diffusion is completely meaningless. I wonder how to remove the diffusion contribution entirely from the model, as it does not converge at longer periods of time. I may be able to simulate up to 20 secs only, and hours are needed.
