HTC STX

021 Heat Transfer Consultant STX v3.5 for wXP users only The STX program is designed to assist the heat exchanger engineer to obtain competitive and reliable designs for industrial TEMA type shell and tube heat exchangers. Some of the features of the program are described briefly in the following paragraphs. STX operates in the design, rating or evaluation mode. A case optimization routine will optimize the length of the exchanger with respect to cost. A special routine is included for vertical thermosiphon reboilers and falling film evaporators. Many different cases may be run at once in the special batch mode. Design determines the surface area and exchanger dimensions for specified process conditions Rating determines the amount of excess surface area and available fouling factor for a specified exchanger and operating conditions Evaluation checks to see if the exchanger will perform
