Oil & Gas Elevated Flare System With EPC Contrating Service , Enclosed Flare System
Flare System is to handle the discharged combustible gas under the conditions of normal operation, start-up, shut-down and emergencies, which ensure the gas to be flared out instantaneously, safely and reliably and to meet the demand of environmental protection.
Flare System is a kind of safety equipment comprised of pipeline, knock out device, fire retardant equipment, flare burner, ignition system, flare riser and other components.
Flare Categories:
* Based on the vent gas media’s physical parameters (mainly for toxicity of the vent gas media), discharge pressure, flow rate and so on, the flare shall be divided into two categories – elevated flare and ground flare.
* The elevated flare, based on the support way, shall be divided into self-supported flare, inhaul supported flare and derrick supported flare. The derrick supported flare, based on types of the riser to be fixed, shall be divided into fixed derrick supported flare, demountable derrick supported flare.
* The ground flare, based on vent gas treatment capacity, shall be divided into enclosed ground flare and open ground flare.
* Based on structure of flare burner, the flare shall be divided into steam-assist flare, forced draft assist flare, defused flare, LHV flare, multi-hole collision flare, sonic flare, etc.

Working principle / flow process
Elevated Flare System: The combustible gas is discharged from production equipment, flows into the battery limit of flare through vent pipe network, flows into the knock-out drum for separation of liquid drops probably contained in vent gas, flows into the water seal drum and breaks through the water seal, and then flows into the flare riser, goes through the molecular seal and finally is flared out by the burner.
