FRI has tested various types of fractionation trays and packings (both generic and proprietary designs), with the objective of developing correlations for predicting tray efficiencies and  pressure drops. This information is needed to design fractionators, absorbers and strippers. It has also tested performance of other column internals such as liquid distributors. It periodically reports its findings to the member companies.
The OSU library  maintains an unrestricted collection of FRI progress reports, plant tests, topical reports, consultants’ reports and annual reports that were issued during the period 1954 – 1970. 
FRI has also produced a number of unrestricted instructional films and videos, which are listed on its home page. These are available to non-members.
