Heat Transfer Research Institute

There are also two notable research institutes offering information that may assist the engineer in making out the specification sheets. One of these is the Heat Transfer Research Institute (HTRI). Its staff performs tests to optimize the design of heat-transfer equipment. This information is then encoded in computer programs, which are distributed to the companies that support the research. This means that the engineer s company must purchase a membership to obtain these data. The Fractionation Research Institute (FRI) is a similar institution that deals with the separation processes. 

The fouling factor has to be determined from actual heat exchanger performance based on online measurements taken from a process unit test run. Heat exchanger clean performance is obtained from process flowsheet simulation software (e.g., Hysys by Aspen Tech or Unisim by Honeywell), while dirty performance from exchanger rating software (e.g., HTRI by Heat Transfer Research Institute).

A NATO Advanced Study Institute was held, between July 18 - 30, 2004, in Qe me-Izmir, Tiirkiye to discuss the fundamentals and applications of microscale heat transfer in biological and microelectromechanical systems. During the institute, the most recent state-of-the-art developments have been presented in considerable depth by eminent researchers in the field. This current volume, edited by Kaka et al. [19] brings together the important contributions from the institute as a permanent reference for the use of researchers in the field.

Entrained flow fast pyrolysis was developed at Georgia Tech Research Institute (25) and scaled up by Egemin (26), Further details are available in (14). Neither the GTRI nor Egemin process is now operational and there are no known plans for further development, probably because of the difficulties that have been encountered in achieving good heat transfer from a gaseous heat carrier to solid biomass. Liquid yields of 50-60%wt. on dry feed have been obtained.
