Application Spotlight: Batch Process Water Heating

Thermal Products Inc was asked to design a Shell & Tube Heat Exchanger within a certain footprint as it needed to fit within our customer’s packaged heating system. We offered to design and build an all 316 Stainless Steel Shell & Tube Heat Exchanger, but our customer requested 304 Stainless Steel Shell & Tube Heat Exchanger instead. Our customer also requested the tube side connections of our shell & tube heat exchanger to be Tri Clamp connections for ease of cleaning the heat exchanger.

The design parameters for the project were to heat 300 gallons of process water from 60 degrees Celsius to 80 degrees Celsius in 15 minutes or less. Our customer’s control package needed to maintain tight temperature control with a +/- .5 degrees Celsius discharge temperature variance for their exacting process downstream. The circulating process water flow rate for each batch will be 120 gallons per minute (GPM)

The 304 Stainless Steel Shell & Tube Heat Exchanger was designed to be a 08024, Type BEU with 304 stainless steel tubes and a 2-pass tube side design. The thermal duty was achieved using 387 lb/hr of steam and was built to ASME Code Section 8, division 1 and TEMA C.

Thermal Products sales and design engineers can design a fully customized heat exchanger to your exacting specifications or an "off the shelf" design for quick shipment and installation.  Thermal Products can supply the heat exchanger alone or integrate it into a skidded package with controls, valves and pump(s) on a skid enabling a more "plug and play" design, significantly reducing our customers installation costs.

Thermal Products was approached by a regional Paper Mill to design a Semi Instantaneous Process Water Heater utilizing excess steam to trim heat process water for a new product line which required a slightly higher water temperature than what existed already.

Thermal Products designed a skid package that included the following equipment:

  • Skid Assembly  
  • U-Tube Heat Exchanger ASME Code Stamped, Model TPI-06-048-2P to heat 62 GPM water from 35.5F to 68F using 50 psi steam 
  • 3" Steam Valve
  • 1-1/2" Steam Trap
  • 3" 150# Y-Strainer
  • Check Valve
  • 150# Class Butterfly Valves
  • High Temperature Limit Aquastat
  • Temperature Relief Valve
  • Temperature Controller from Johnson Controls
  • Spool pieces and piping
  • Painted

Skid package was then painted to custoemr specifications with a 2 part epoxy

Thermal Products can also offer the following equipment for a skid package to fit your specific application.

  • Pump
  • Shell & Tube Exchanger
  • Plate & Frame Exchanger
  • Electric Circulation Heater
  • Air Cooled Exchanger
  • Isolation Valves
  • Controls package
  • Control Panel
  • Various Materials of Construction
