In heat exchanger thermal design, this means HTFS, an unparalleled suite of research-validated software. The quality of HTFS is recognised by leading companies worldwide who rely on the methods developed and supported by a unique team of heat transfer experts. HTFS software is based on over 30 years of industrially-led in-house research aimed at reducing the cost of design, manufacture and operation of heat transfer equipment.

Application of these accurate, proven solutions, equipment can be confidently designed with less heat transfer area and better pressure drop performance, bringing reductions in material and manufacturing costs, as well as savings in plant operation and production.

HTFS is committed to providing easy-to-use products that unlock the full potential of heat transfer specialist, process engineer in design or operational environments. HTFS software comes complete with extensive screen based help, on-line program manuals and global support, so you are assured of an immediate, trouble-free HTFS solution. It can be run in conjunction with the HYSYS process simulation software from Hyprotech and also has interfaces to third party property databanks, software from Aspen Technology Inc.

Properties data can be set up and reviewed prior to the main flow and heat exchange calculations. Subsidiary properties facilities available include the component NEL40 databank, which can be used in conjunction with any component for which you provide data, and options to store and recover stream properties in your own databank.

HTFS programs can import process and properties data from all the main process simulators. The Simulation option in TASC is of extended form permitting either inlet conditions, or outlet conditions or flowrate to be calculated for either stream given the other two parameters. Design is an integrated graphical process aimed at establishing the overall size and configuration of process air-cooled heat exchangers.

Up to 4 different types in each bundle. Exchangers can be modelled with up to 15 process streams in co- or counter-current flow and any complexity of exchanger inlet and outlet geometry. Single units and multiple blocks in series or parallel with vertical or horizontal orientations, can be modelled.

Thermosyphon reboiler calculations can be performed for either internal or external types. The programs can also be used for plate-fin heat exchangers in stainless steel or titanium. Extensive pressure drop calculations are available for common layouts of inlet and outlet distributors and checks are made for possible flow distribution problems. Simulation can be on a stream by stream or layer by layer basis.

PSF file link to process simulators. Having one stream single pass and the other multi-pass is also permitted. Plate geometry can be specified for other calculation types.

Iteration takes place over four different chevron angles, and if appropriate over a range of plate sizes to establish possible designs. Chevron angles can range from 30 to 65 degrees angle to horizontal. Calculations are performed on a more detailed basis, with each pass in the exchanger being modelled separately, with 25 calculation points per pass. Full allowance can thus be made for non-linear temperature profiles, and for variation in heat transfer coefficients and pressure gradients.

The effects of any flow maldistribution among the plates are also handled. Non- Newtonian fluids are also handled. Allowance is made for bends, fittings and changes of section, single or two-phase flow, and single or multiple chokes. The program relates the inlet pressure, outlet pressure and flowrate in a pipeline. Given any two of these parameters the program calculates the third.

For other baffle types details of heat transfer and pressure drop correlations must be supplied. Condensing zone - baffles are considered to be full circle, such that the predominant flow direction is crossflow. If there are significant differences, they will be reported in the Read Me. In conjunction with extensive reviews of open literature methods they provide HTFS software with a unique technical base. Many companies require access to underlying heat transfer and pressure drop models used in the software.
