Industrial Process Tomography is a general term for techniques intended for cross sectional or 3D imaging of material properties and distributions in various industrial positions such as in pipes, vessels and reactors. Process tomography covers several tomographic techniques, e.g. electrical, X-ray and ultrasound methods, and typical applications include e.g. monitoring of different mixing and sedimentation processes as well as determination of material concentrations and distributions in multiphase flows.
An important feature of tomographic techniques is that the measurements are typically carried out from the periphery of the target using a specially designed sensor so that the measurements do not disturb the process. Tomographic measurements enable non-invasive process monitoring, which can give comprehensive understanding on the behavior of the process system and provide valuable information for process optimization and control.
