LPG (liquefied petroleum gas) is used in industrial, commercial, agricultural, and manufacturing applications.
LPG is a mix of propane (C3H8) and Butane (C4H10)
Simple Skid:
LPG Skid Station (Autogas Filling Sation ) , it is mobile station builted on steel chasssis used for filling car or gas cylinders
Dispenser single or double nozzle can be used for filling car or gas cylinder , the dispenser can mesuaring by ( LT) or ( kg - mass flow )
The scales used for filling gas cylinder, the scales can be mechanical or electronic ( digital )
The welding tests that can be done : UT (Ultrasonic Test ) and RT ( RadiographicTest ) for joints, BT Test will be done for welded flanges
The hydrostatic test will be done by water pressure according to code by THIRD PARTY
Skid with automation system :
This kind of skids provided with tank gauging system
In this case the skid will be automated by adding automation devices : gauging probe, software connected to PC ...etc
This software connected to this system can show all needed reports for user , like daily report , shift report, density ,gas level in the tank ...etc
The system provided with high safety shut down system by adding sensors around station ,these sensors connected to electronic panel
In case of gas leakage from the system, the gas sensor will give the order to system to shut down by closing the Pneumatic valves and LPG pump that connected to this system
