Ms LPG/ Propane Liquid Trap:

liquid trap or Heavy Condensate Trap are devices that are installed downstream of the vaporizers to accumulate and drain out heavier hydrocarbons that are sometimes present in LPG. Using Liquid Trap leads to clean burning and avoidance of several safety hazards and accidents.
Working Principle
LPG vapour enters the Liquid trap to pass through a series of baffle plates resulting in accumulation of heavy hydrocarbons at the bottom. The LPG vapour without the heavy ends goes to the burner from the outlet of the liquid trap.
Location of Installing the Liquid Trap
Liquid Trap is installed outside the shop floor on the secondary pipeline. It is important to ensure electrical connections do not exist within 2 meters of the trap and no hot work is to be carried out within a radius of 10 meters.
