LPG System
Liquefied Petroleum Gas (LPG) is a term used for hydrocarbon gases. It is produced either as a by-product when refining crude oil or direct from the North Seas oil or gas wells.

The two most common LPG gases are known as Commercial Propane and Commercial Butane as defined in BS 4250. Commercial Butane is predominately stored in blue cylinders up to 15kg and generally used for leisure applications and mobile heaters.

Commercial Propane is predominately stored in different color e.g. Red, yellow etc. cylinders and bulk storage vessels and especially used for heating, cooking and numerous commercial & industrial applications.

LPG has one key characteristic that distinguishes it from Natural Gas. Under modest pressure LPG gas vapor becomes a liquid. This makes it easy to be stored and transported in specially constructed vessels and cylinders.

Description of LPG System:

Gas Meter



LPG Tank : LPG Storage Tank is designed, fabricated, tested and marked in accordance with International standards and is approved by Dubai Civil Defense. LPG Storage Tank is consist of pressure relief devices, container shut off valves, backflow check valves, plugs, level gauges and pressure gauges connected directly into the container openings.

Pipes & Fittings : Provide Pipe and fittings in accordance with NFPA 58.

Valves, Other than Container Valves Isolating valve is as per L.P. Gas application.

Gas Leak Detection System : The central control panel shall be located in the control room located on the site and shall easily be accessible in the event of an emergency. The concentration of the gas shall be displayed on a common indicator with selector switches to display the concentration of the desired channel or zone indicator. The gas detectors shall use a sensor to detect flammable gases and vapors. The sensor shall be housed in a stainless steel, flame proof housing, fitted onto an explosion proof junction box.

Vaporizer : 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.

Gas Meter : Gas Meter is used to measure the flow of fuel gases such as natural gas and propane. Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility. Gases are more difficult to measure than liquids, as measured volumes are highly affected by temperature and pressure. Gas meters measure a defined volume, regardless of the pressurized quantity or quality of the gas flowing through the meter. Temperature, pressure and heating value compensation must be made to measure actual amount and value of gas moving through a meter.
