LPG Vaporizers
Overview

Alternate Energy Systems manufactures liquid Propane/Butane vaporizers with capacities from 168 gallons per hour (322 kg/h) to 14000 gph (28000 kg/h). To meet the requirements of customers and particular applications around the world, we are employing a variety of design concepts and configurations. Their heat source can be hot water (Water Bath Vaporizers; Circulating Hot-Water Vaporizer) or steam (Steam Vaporizers). The vaporizers are manufactured to the rigid codes of the American Society of Mechanical Engineers (ASME), the latest edition of NFPA #58 and/or #59, and most are approved for Factory Mutual (FM) or Industrial Risk Insurers (IRI) installations, in addition to approvals by Canadian Standards Association (CSA), American Gas Association (AGA), and Canadian Gas Association (CGA). European CE Approval, including ATEX, PED, and other applicable Directives, is available for all Water Bath Vaporizers.

As a manufacturer, we go far beyond the requirements and codes and are continually working to produce equipment with the most modern engineering techniques available.

WHAT IS A PROPANE/BUTANE/LPG VAPORIZER ?

LPG (Propane, Butane, or Propane/Butane Mixture) at ambient pressure (above its boiling point temperature) is a gas that is stored in pressurized containers (tanks) in liquid form. The space in the tank that is not filled with liquid is occupied by vapor. As this vapor is being used as fuel for connected equipment (burners, heaters, etc.), liquid LPG must vaporize (change its state from liquid to gas) to occupy the space above the liquid.

Any time a change of state occurs, energy is required. If the ambient temperature is above the boiling point of the LPG (Propane -44°F / -42°C; Butane 32°F / 0°C at ambient pressure; see chart for the boiling temperature of LPG at various pressures), this energy is transferred in the form of heat from the ambient air through the steel walls of the storage tank, into the LPG. As the heat is transferred from the ambient air to the vaporization process, the ambient air "looses" this energy and cools down.

The amount of heat that is transferred into the LPG determines the rate of vaporization. As the ambient air cools down, the rate of vaporization slows down, and stops completely when the ambient air is at the same temperature as the boiling point of the LPG. Therefore, naturally occurring vaporization cannot be used for large gas loads, or in low ambient temperatures.

A vaporizer is designed to receive the liquid LPG and raise its temperature (heat the liquid) well above the boiling point at the delivery pressure. In other words, a vaporizer generates the (heat)energy that is required to maintain the gaseous state of the LPG.

There are two major types of propane vaporizers: Vaporizers that supply a small portion of the vaporized LPG as fuel for the burner that supplies the heat for the vaporization process (i.e. Water Bath Vaporizers); and vaporizers that use an outside source of heat, such as steam or hot water, to vaporize the propane.
