The LPG air mixing supply system has become instrumental in the development of natural and other alternative energy sources. In some circles, it is referred to as an SNG (Synthetic Natural Gas) supply system. There have been a number of breakthroughs which have international implications over the past few years.
The reason this was first developed is LPG vapour is not directly compatible with natural gas. This means it must be mixed with air before it can be used in any piece of equipment or appliance that is set up to be powered by gas. These system typically utilizes vapour from a specific vapour source, such as a vaporizer. This ensures the vapour can be mixed with air at a constant, predictable ratio. The resulting product is referred to as synthetic gas. Unlike LPG, synthetic gas is directly compatible with natural gas. This allows users to easily switch back and forth between natural gas supplies without having to change the setup of their equipment or appliances.
A complete LPG supply system is composed of multiple parts and each part has specific characteristics which must be considered when choosing the right system for a particular building, home, or appliance. The first section of the system is the LPG storage tank, gas compressor, LPG Feed pump, and LPG vaporizer. This section of the supply is dedicated to managing and preparing the LPG before it is mixed with air. Within this section, the system primarily deals with LPG in liquid and vapour form. By storing it as a liquid a significantly greater amount can be stored. This is not only less expensive, but it takes up less space and minimizes the number of necessary refills during any given period of time.
The second section of the SNG supply system is the LPG Air mixer, Auto actuation system, surge tank, and pressure reducing unit. This section of the supply system begins when the LPG is actually mixed with air. As soon as this happens, a specific odour is added to the air. This is the smell people have become accustomed to associating with cooking gas. The truth is natural gas is odourless which is extremely dangerous. Safety precautions are why an odour must be physically added to the natural gas.
The final section of the LPG supply system includes the air compressor, air receiver tank, and air dryer. This section of the system is primarily responsible for the dispersal of gas once it has been made usable. It also removes any additional vapour to ensure the gas does not carry any moisture into appliances and equipment.
While an LPG air mixing supply system may seem like a complicated process, companies have created a machine design which allows the entire supply system to be stored in a comparatively small amount of space.
