produces electrical power or produces both electrical power and heat energy.
heat exchanger to recover boiler blowdown. The program calculates the amount of flash steam and saturated
condensate that will separate when a high pressure, high temperature water steam is flashed in a tank of
lower pressure. It then assigns a dollar value to each of the two components based on the value of fuel,
boiler efficiency, etc.
specified diameter and internal temperature. It then calculates the present worth cost, $/foot, to own
and operate each insulated system. This allows the user to select the optimum insulation thickness for
each pipe based either on the cost of the insulation and heat loss or on the maximum acceptable surface
temperature. Four types of insulation are supported. Pipe sizes through 36" are included. Three layers of
insulation are supported ranging in thickness from 0 to 10".
PHEdesign (Plate Heat Exchangers)
and material properties, the optimum plate dimensions and materials can be selected by the computer program. These
are included rate of heat transfer, the size of plate heat exchanger, and chevron angle (beta) between 25 to 65
degrees under single pass condition. Also this program is capable of calculating the pressure drop in plate, from
which the energy and material can be saved by decreasing the pressure drop (decreasing horsepower per unit area)
and increasing chevron angle
that a furnace can be sized. Heat transfer coefficients are built in for many types of wall, floors,
doors, windows, etc. Custom values can also be used. The heat needed for infiltration & humidity
control are also calculated. Final furnace sizes are tabulated with several values of efficiency.

The steam and condensate properties are built in. Also a complete range of tube properties are built in.
The cleanliness of a given condenser can be etermined quickly using a trial and error method.
mechanical-draft, counterflow cooling towers. The program can be used for the analysis of existing
towers or for the preparation of specifications for new towers.

be specified. The shell-side fluid is always steam. The tube side fluid can be any non-condensing fluid.
boiler (Heat Recovery Steam Generator). The steam and condensate properties are built in. The program first
calculates a design mode and then an "off-performance mode" for changed conditions.

Heat Exchangers: Shell & Multi-Tube Exchangers, and Double Pipe Exchangers. In either case, the tubes are of the
bare-tube type. The program will analyze the performance of a known heat exchanger: Given the flows and inlet
temperatures of the Tube-side fluid and the Shell-side fluid, the program will predict the exit temperatures
of both fluids and the total heat exchanged.
your best source of data. Through the use of menus: data and functionality are put at the finger tips of the
power user. Tri MAXTM provides data such as periodic table, steam tables, heat capacities, critical values,
viscosities, diffusion coefficients, thermal conductivities. Math functions are also provided, such as linear
regression, quadratic equation, curve fitting, and a calculator that goes far beyond the standard calculators
available for MicrosoftTM Platforms.
Gas Association methodology from their AGA-8 Report. The software quickly takes a mixture of natural
gas (up to 20 components) and calculates the compressibility, molar density, mass density, base
compressibility and supercompressibility.
process calculator. Steampak's algorithm is based on the equation of state of Keenan, Keyes,
Hill and Moore which is the basis of the published International Steam Tables. The process
calculator allows calculation of steam compression and expansion processes at user-selected
efficiencies including isentropic & adiabatic expansions and flash calculations.
functions of temperature and pressure. All common chemical engineering constant and variable
properties are included. Liquid and vapor phases are covered as well as saturated and
unsaturated states. Mixtures of database compounds and new liquids can be defined.
Numerical and graphical output are supported. Chempak links to Chempak II - Madison's
user-defined compounds software package.
of new compounds not already in the Chempak database. From as little information as the
compound chemical formula, the user can build up a complete profile of the compound
properties and add the compound to the Chempak database for future recall and calculation.
Chempak II allows the user to enter known property data and also provides sophisticated
estimation methods where no data is available. Chempak II provides the perfect companion
software to Chempak.
In addition it calculates the properties of saturated water.
water using IFC formulation for industrial use. Knowing any two properties, the user is able
to completely define the properties of water/steam. Unlike most steam table programs, this
program also provides the user with the point's location on the T-S diagram. Multiple points
can be connected by a line, defining the user's process system. It even gives you the steam
