Device Testing & Projects

Device Testing

FRI’s experimental program includes the testing of proprietary trays and packings currently in the market. Members vote each year to test one tray device and one packing device at the experimental unit. The FRI staff then collaborates with device vendors to design and execute a testing program to determine the devices' hydraulic and mass transfer performance. The results of the tests are documented in reports and videos, and also included in the FRI Database. The FRI experimental program also includes a vendor-paid test on a new device, not available in the market, of the vendor's choosing. This information remains confidential to the vendor but many vendors decide to share the results with the membership.

Below is a partial list of the trays and packings tested at FRI.

A diverse mix of projects make up the testing program at FRI. Research and Development projects are a key part. The FRI Prospectus currently lists 57 projects identified by the Members. These projects include device specific, development research, modeling, and physical phenomena research. The projects with the highest membership interest are listed below in the Long Range Plan.

FRI also incorporate parallel projects, which tests auxiliary hardware, software or equipment used by FRI Members. FRI works with industry partners to incorporate these tests with the overall test program, document the results for the FRI Members. This partnership allows Members access to test results of technology or products from reliable third party and FRI access to cutting edge technology. We have listed some of our parallel projects below.
