Why Join FRI? 

Lower capital costs - The information and tools provided with FRI Membership enables more accurate designs of new distillation columns (smaller diameter/lower height) and more cost effective revamps of existing columns (getting the most out of existing hardware).

Fewer operating problems and less time off spec - The know how embodied in FRI methods and tools enables engineers to more quickly troubleshoot problematic operations of existing distillation towers and get tower operation back to target.

Software & Correlations

FRI software, such as the Device Rating Program (DRP), has been shown to have higher levels of accuracy than other available methods when calculating tray and packing capacities and pressure drops. FRI experimental work in our 1.2 meter and 2.4 meter diameter columns forms the basis for our software and correlations. These tools are used by FRI Members to understand the impacts of various hardware choices when designing or evaluating distillation internals.  These correlations have been created from testing hydrocarbon systems with a broad range of liquid and vapor densities, surface tensions, and viscosities. 

Member Driven Research

One Member = One Vote

FRI's testing program is specified by the members and executed by FRI.  Each Member company has one vote in the process to guide the research program. The research program contains a mix of basic distillation research and testing of proprietary devices.

FRI research will help to understand new distillation hardware, enabling Members to save money and improve operations. FRI's work helps build confidence in new devices through our Proprietary Device Testing program. With this program, new proprietary distillation internals are tested.  These tests provide consistent information to compare the performance of new devices that the members may be considering purchasing. 

The purpose of FRI is to execute member-driven, well-planned experimental programs to collect large scale mass transfer hardware performance data with industrially representative chemical systems, and to report such data to its members clearly, in useful formats, and in a timely manner. 

Design Handbooks

FRI provides the Members with electronic access to the Design Handbooks. These handbooks help trouble-shoot problems, investigate industry best practices, and build fit for purpose distillation facilities. 

Volumes 1 through 4 provide guidance on the design of different types of distillation internals.  Volume V is the comprehensive FRI Design Practices Handbook.  It is authored by the Design Practices Committee which is comprised of distillation experts from roughly 20 of the Member companies.  Volume V provides guidance on the many auxillary issues that are so important for successful design and operation of distillation columns.


Meetings throughout the year provide an opportunity to interact with the distillation experts from other Member companies, including some of the best distillation experts in the world. These networking opportunities will allow for troubleshooting problems with others in the industry. Members actively collaborate to solve operating problems.
