VOC Destruction Technology

BGR Combustor Description

Available Models: BGR-18 LP & BGR-24 HP/LP

BGR-24 - 24"x26' free standing LP vapor combustor and HP flareBGR-18 – 18”x10’ free standing LP vapor combustorNo visible flame from low pressure burnersLow pressure volumes:

BGR-24 – 24,048 scfd w/pilot at >99.9% destructionBGR-18 – 12,960 scfd w/pilot at >99.9% destruction

Excellent low pressure turndown ratio of 75:1BGR-24 high pressure volume: 1.7 MMscfd from 3” flare tipL/P burner air inlet provides air assist for H/P flameACL 3200 dual ignition control system with:

Remote start/stopAuto re-lightTemperature sensing and monitoring (if required)Solar operating 12/24 volt dcModbus communication built inData logging

ApplicationsCrude oil, condensate, and produced water tank vents; glycol dehydrator flash tank vents, regenerator still vents, and wet seal compressor vents, and casing gas venting.Sites with no gathering systems for gasFacilities which require low pressure vent control and high pressure flaring

High Pressure Dispersion Modeling

Worst-case, conservative, screening approach and assumptions:

H2S at 1.5 volume %; 1.115 MMscfd flowH2S at 1.0 volume %; 1.7 MMscfd flow100% conversion to SO2; 99% destruction of H2SU.S. EPA AERSCREEN model

Results demonstrate compliance with Alberta and Saskatchewan limits

1-hour, 24-hour, annual SO21-hour and 24-hour H2S (no annual limit)

HP Radiation – 26’ High Stack

Recommended thermal radiation levels and calculations based on API Recommended Practice 521.Should be set ~95 feet from personnel work areas.

Benefits of BGR Low Pressure Vapor Combustors?No additional fuel, air, or steam assist required,

can be operated on waste gas only with no visible flameNo expensive control systems or valve trains requiredCan operate via solar power for remote sitesOperate as low as 2 oz pressure from storage tanks while maintaining at least 99.9% destructionEqual combustion efficiencies to more costly thermal incinerators and oxidizersIdeal for storage tank, casing gas and dehy unit low pressure ventingProven technology through 3rd party testing

Benefits of BGR-24 L/P-H/P Vapor Combustor?

High pressure line capable of large volumes during upsets and emergenciesReplaces separate L/P and H/P flare stacks while remaining compliantLow radiation impactsHP flare is NSPS Subpart A (40 CFR 60.18) compliant up to 1.7 MMscfdState of the art ACL Manufacturing burners and burner controlsInexpensive alternative to incinerators and separate L/P and H/P flare stacks
