HTRI is a for-profit membership R&D consortium focusing on heat transfer in process industries. Members from all over the world include major engineering firms (e.g., ABB, B&W, Bechtel, Black & Veatch, Brown & Root, GE Power Systems, Kvaerner, Stone & Webster, etc.), major oil and chemicals companies, equipment makers, and exactly one utility (Ontario Hydro).
HTRI wants to increase its involvement with utilities, and has approached UFTO for help. While their work hasn’t yet addressed some of the core power plant systems (steam generators, surface condensers, etc.), they could certainly initiate programs in those areas.

At the same time, utilities do have innumerable other heat exchangers and heat transfer applications that are addressed by HTRI (e.g., shell-and-tube heat exchangers).

Perhaps more important, conventional steam boiler technology is being supplanted by combined cycles — primarily natural gas-fired at this time, but likely to include more coal, residual oil, and biomass gasification in the future. The major heat exchanger in a combined cycle plant — the heat recovery steam generator (HRSG) — is a relatively new type of heat exchanger in terms of widespread commercial use. There will be many challenging design and operating approaches and challenges associated with HRSGs as combustion turbine and steam turbine designs evolve into higher temperature regimes.

Also, it’s worth mentioning that utilities (or ESCOs) could use HTRI resources in their continuing role of helping industrial customers be more efficient, productive and successful.

Thus, there would appear to be a number of ways HTRI and the electric power industry could grow together. As one example, HTRI is planning a new “sub” consortium to address heat exchanger fouling, certainly an important topic for utilities.

HTRI products are based on decades of member-sponsored proprietary R&D, and are not available on the open market. HTRI members have access to HTRI’s product line and become part of a research consortium comprised of industry leaders from around the world—all for less than the salary of a single additional engineer. (Membership fee varies with size of company–to a maximum of approximately $50,000 per year.) Subsidiaries of a member company may also use HTRI products, if they are more than 50% owned.

Joining HTRI is like adding a dedicated team of heat transfer experts to a member’s company. Members gain access not only to our software and research data, but also to the collective experience of the staff. HTRI technical support can improve productivity with expert answers to questions about software, methods, correlations, and research, as well as theoretical questions concerning heat transfer and exchanger design.

— History

Incorporated in 1962, Heat Transfer Research, Inc. was chartered for the purpose of conducting application-oriented research on large-scale equipment in the general field of heat transfer and associated fluid flow, and converting the results into dependable design methods for industrial purposes. This was a depar-ture from the more typical method of companies conducting individual experiments based on university-derived theory. A few years later, the company moved from Bartlesville, Oklahoma, to Alhambra, California, and continued to grow in size and reputation. While in California, HTRI’s experiments were conducted on research units located at C. F. Braun, Inc., an HTRI member.

In 1990, HTRI relocated from California to College Station, Texas, where we built a multi-million dollar research facility with industrial-scale units. This strategic location also provides collaboration opportunities with the Texas Engineering Experiment Station (TEES) and Texas A&M University, one of the United States’ top engineering schools.

— Research Facilities
The HTRI Research Facility, developed in 1991, is a well-equipped multimillion dollar experimental facility. The site has four research units with supporting facilities and equipment. The facility can be customized to meet the changing needs of our customers. We also are available to conduct research and construct new rigs under contract.

The facility’s physical plant includes a 500-horsepower Johnson Boiler with a heating capacity of 17 million Btu/hour and a two-cell Marley Cooling Tower with a cooling capacity of 21 million Btu/hour. The machine shop includes welding equipment, a milling machine, lathe, drill press, band saw, and pipe threader. Instrument calibration and electrical tests are performed on site using a variety of testing components.

A laboratory also is on site to perform tests ensuring compliance with environmental regulations and to analyze test fluids from the research units.
– High Temperature Fouling Unit – provides data for defining process operating conditions and exchanger design features so that fouling of typical industrial fluids can be minimized. A wide variety of fluids can be tested, including gas oils and crude oils. The unit can operate at up to 1000 psig (6,895 kPa) and 800 °F (427 °C). The HTFU has two test sections that can operate simultaneously at different conditions.

– Multipurpose Boiling Unit – provides flow boiling heat transfer and pressure drop data for pure fluids, hydrocarbon mixtures, and alcohol-water mixtures. The MBU can operate over a range of conditions typical of industrial heat exchange processes.

– Single Phase Unit – (formerly known as the Plate Heat Exchanger Unit) provides information to develop heat transfer and pressure drop methods in single-phase flow. This unit has two plate-and-frame heat exchangers, a spiral heat exchanger, and a welded plate heat exchanger. The SPU can operate under a wide range of conditions with a variety of process fluids.

– Vertical In Tube Condensation Unit – provides data used to develop heat transfer and pressure drop methods for intube condensation. A variety of fluids including alcohols and hydrocarbon mixtures with and without inerts can be tested. The unit can operate from low vacuum to 450 psia.

— Software
Software modeling and simulation tools, based on proprietary, relevant, and quality research, helps HTRI members design efficient heat exchangers.

HTRI software methods are derived from extensive research and documented in our publications. Many of the research programs are ongoing, leading to continual improvement of methods and simulations. All software accepts data in U.S. Customary, SI, and MKH units (except our Fired Heater program, which currently accepts U.S. Customary units only). Most programs have identical user interfaces and input structure: process conditions and physical properties are specified similarly, using the same data input lines. To ease interpretation of data, printed output follows a standard format in nearly all applications.

Interfaces between our software and other computer programs allow easy data transfer to process simulators, mechanical design systems, and database systems. Interfaces are available for software from such companies as AspenTech, B-JAC, Bryan Research & Engi-neering (BR&E), Physical Properties Data Service, ABB Lummus, SimSci, and others. HTRI is a member of the Process Data eXchange Institute (pdXi).

Before release, every HTRI program undergoes a rigorous testing process on several different platforms. These tests verify software results against HTRI’s proprietary research data. Test sets are extensive, making use of as many as 2,600 separate cases.

– ACE rates and simulates air-cooled heat exchangers and economizers. The program handles forced draft, induced draft, and “fans off” air-cooled heat exchangers. The economizer option also may be used to rate air preheater bundles. ACE is a fully incremental program.

– CST, using a fully incremental approach with HTRI’s latest pointwise correlations, designs shell-and-tube condensers from a set of process conditions and rates the performance of a geometrically specified condenser. Used with confidence since 1974, CST handles TEMA E, F, J, and X shells.

– FH simulates the behavior of fired heaters. Its capabilities include the solution of combustion and tube design problems and the simulation of cylindrical heaters, box heaters, and convection tube banks.

– IST rates the performance of geometrically specified shell-and-tube heat exchangers. A fully incremental program, IST contains HTRI’s latest pointwise equations for predicting condensing, boiling, and single-phase heat transfer and pressure drop. IST handles TEMA E, F, G, H, J, and X shells.

– PHE rates plate heat exchangers for liquid-phase applications. The program uses average local properties within each plate group. Various plate types may be selected from an automatic data bank or entered manually.

– RKH designs and rates kettle reboiler, column internal bundles, and horizontal thermosiphon reboilers.

– RTF designs and rates shell-and-tube vertical thermosiphons and vertical or horizontal forced-flow reboilers with the boiling on the tube side. The program also rates spiral plate reboilers. RTF is a fully incremental program.

– ST designs single-phase shell-and-tube heat exchangers from a set of process conditions. It also rates the performance of a geometrically specified exchanger. ST handles TEMA E, J, X, H, G, and F shells.

– ST Educational is an educational package for engineers wanting to learn about or review shell and tube heat exchanger calculations. Utilizing the full calculation engine from ST, this product provides companies and educational institutions with an accurate and user-friendly training tool.

– TWALL calculates the mean tubewall metal temperature in each tubepass for a TEMA E shell with fixed tubesheets. The TEMA Standards use these temperatures in their design equations.

– VIB conducts a rigorous analysis of the vibration of a single tube in a tube bundle. Additionally, VIB calculates natural frequencies for up to 15 modes.
