Packaged Systems: WaterBath Vaporizer & POM Blender
Horizontal Water Bath Vaporizers with POM Blender Modules Overview

These skid mounted, packaged systems combine WB-series water bath vaporizers and our patented Piston Operated Mixers, POM. They are designed for capacities of 15 MMBTU/h (3.5 MMkcal/h) to over 500 MMBTU/h (125 MMkcal/h) and are manufactured to meet or exceed requirements of the ASME Pressure Vessel Code and latest edition of NFPA Pamphlet #58. Complete with interconnecting piping and wiring, they are ready for connection to liquid propane inlet, properly sized electrical and mixed gas outlet.

 

Requiring clean, dry compressed air for operation, the blending system is usually installed on the same concrete pad as the vaporizer, but can also be mounted in vertical orientation next to the water bath vaporizer (see drawing on left). Applicable for continuous duty or total stand-by, the units are designed for better than 50:1 turndown ratio. The PLC-based control system provides real-time information on vaporizer and blender status, first-out failure analysis, alarm history, graphic trend recording, and color LCD display with touch-screen operator interface.

The vaporizer model number (WB) designates gallons per hour propane vaporization at 0 °F liquid temperature, and the blender is sized according to millions of BTU per hour propane-air mix requirements. For detailed information, please refer to the sections for water bath vaporizers and piston operated mixers.

 

AES Module Units include the following features:

  • Designed to supply Propane-Air Mixtures compatible with Natural Gas requirements of 15MM BTU to over 500MM BTU per hour.
  • Vaporizing and Mixing units are skid mounted.

  • Forced-Draft Power Burner.
  • Electronic Flame Safeguard System.
  • Electronic System Controls (PLC) with First-Outage Monitor and Digital Operator Interface. Color LCD display with touch screen operator interface standard.
  • Controls are mounted in weatherproof cabinet.
  • Units are factory tested, primed, painted and ready for installation and connection to vaporized liquid propane supply.

Available Options:

  • ASME "U" Stamp
  • National Board Registration.
  • Enlarged vaporizer control room or separate mixer and control room building.
  • Automatic Gas Properties Control (Wobbe Index, O2 content, Calorific Value, or Specific Gravity)
  • Flow Control System for Peak Shaving
  • Remote Monitoring and Control (Ethernet or Wireless)
  • Integration into existing Plant Control Systems (SCADA)
  • High-Pressure Configuration up to 300 psi / 20 bar

WB-Vaporizer/POM-Mixer Configurations for selected System Pressures and Standard Propane Applications.
Configurations for other LPG mixtures may vary. Other Vaporizer/Mixer combinations are available; contact your  distributor or the factory for details.


** NatGas Equivalent:      In most cases, these systems will be used to provide backup for a NatGas  supply. Including a sufficient safety factor (1.1 ... 1.3), use the  maximum expected NatGas flow per hour to select the correct WB/POM  model.

POM-30, POM-40, and  POM-60 are available with Fisher 99 or Fisher 1098EGR regulators for  installations with sufficiently high LP-vapor supply pressure (100-125  psi) and should be used only if the LPG consists at least of 80%  Propane. Higher Butane content and/or lower LP-vapor pressure may  require different regulator configurations. Specifications are subject  to change without notice.
Model Numbers with Suffix -9 indicate Fisher 99 regulators; Model  Numbers with Suffix -8 indicate Fisher 1098EGR regulators. Call factory  or distributor for price quotation and actual lead times.
