TECH4IMAGING APPLICATIONS

Energy

Multiphase flows and multiphase reactors are commonly encountered in energy industry operations. Such operations include coal gasifiers, carbon capture processes, combustion chambers, oil refineries, oil drilling, pipe line transport, and Fischer-Tropsch synthesis. The inherently complex nature of multiphase flows requires a multi-dimensional measurement technique capable of providing real time monitoring of process dynamics and physical properties of the flow.

Electrical Capacitance Volume Tomography (ECVT) through its real-time imaging, flexible sensor, non-invasive probes, suitability for up-scale applications, and affordable cost provides a solution in these regards. Moreover, the applicability of capacitance sensors in hot environments enables visualization of combustion processes, fuel burning, emissions control, and optimization of energy generation.

Aerospace

Electrical Capacitance Volume Tomography (ECVT) is an electric based industrial imaging system. Its electric nature, low frequency, portability, safety, low profile sensors, and high imaging speed make it suitable for space applications of zero gravity. ECVT has already been applied to imaging Cryogenic Fuel Gauge in zero gravity environments.

ECVT can also be used as an observation and control tool for scientific experiments in space. Examples of potential applications are imaging multi-phase flows in zero gravity, fuel tank observation in zero gravity, flow measurements, and combustion imaging. The feasibility of ECVT for real-time, 3D imaging of multi-phase flow systems have been established through tests exhibiting zero gravity conditions.

Pharmaceutical

Drug manufacturing often involves multi-phase flow systems. Scalability and flexibility of ECVT sensors provide an invaluable tool to monitoring various phases of drug manufacturing. ECVT capacitance sensors can be designed to visualize flow, mixing, and reaction in the manufacturing process.

The ECVT capacitance sensors can also be scaled down in size to allow for detection of individual tablets during the packaging process of manufactured drugs.

Process Engineering

ECVT technology in process engineering can be used as a diagnostic control tool. Enhancing efficiencies through process visualization is also a major application.

The ability of ECVT technology to provide real-time 3D data that can be fed to a control unit provides controllability measures as well as robust process control. Process operations can also benefit from capacitance imaging by providing real-time optimization.

CFD Verification

A prime application for ECVT imaging is in the area of Computational Fluid Dynamics (CFD) code verification. Our ECVT technology has also been used to create 3D reconstructions of real-time images of flows.

An example of such applications include the recent development of a model for estimating penetration length and size of a side jet into a gas-solid fluidized bed. The model can also be coupled with CFD codes used to model the same phenomena.

Academics

ECVT technology has been extensively used in academics and research settings. Applications include visualization of flow in circulating fluidized beds (CFB), gas-solid turbulent fluidized beds, gas-solid riser flow, gas-liquid bubble column, gas-liquid-solid slurry bubble column, and trickle bed reactors.

ECVT capacitance sensors, through their flexible design, were also used to image flow through side injections, entrance and exit regions, and bent sections. ECVT reconstructed volume images are also being used to develop flow models, verify computational fluid dynamics (CFD) simulations, and discover new flow behaviors.

Infrastructure

Critical infrastructure components require regular inspections in order to detect problems such as moisture infiltration and corrosion. If left undetected, small issues can grow until a problem requires an expensive and time-consuming fix. Worse still, the issue may cause the infrastructure component to fail, resulting in costlier damages or even injuries and fatalities. In infrastructure inspection, the early detection and monitoring of structural problems is key.

Tech4Imaging offers numerous nondestructive testing (NDT) products that provide real-time information about critical infrastructure components. While each of these products vary in use and build, all share key qualities in scalability, safety, size, speed, and services provided. These products and their accompanying software expedite the inspection and report-generation process, allowing smaller crews to inspect more structures in less time.
