Product losses of highly viscous products in pipe systems during displacement processes.

- Abstract
- It is common in the process industry to displace one fluid by another. During the displacement process an unwanted mixing between the two phases is unavoidable and being able to estimate this mixing is of great importance when trying to minimize product losses and improving the quality of the final product.
A method for simulating the displacement process using commercial CFD codes was developed and the effect from varying the fluid parameters was simulated. The method was verified by comparing the results to experimental data. The method was accurate at estimating the breakthrough time but failed to predict the outflow of the residual film.
Finally a simple method based on the maximum velocity of the displaced fluid was investigated... (More) - It is common in the process industry to displace one fluid by another.
