R. A. Nichols Engineering Vapor Burners, come in four configurations. Every burner configuration reduces outlet emissions to less than 0.5% of inlet vapor concentration, less than 5 mg/l, and/or 99+% efficiency.

The first type of burner we offer is a Direct on-line Vapor Burner. In cases where the vapor maximum and minimum flow rates are reasonable, our systems process flow directly from the Equalizer. We currently have burners in operation whose instantaneous on-line flow rates range from 150 cfm to 2,700 cfm. We find a burner alone is most economic in Marketing Terminals when vapor return from service stations, Stage I vapor recovery, is not implemented. On-line vapor burners can also be cost effective in small terminals and in areas where you have a high diesel to gasoline ratio (> 30% diesel throughput). Where vapor concentrations and flow rates are higher, vapor recovery is usually cost effective. Our direct on-line burners can be easily adapted for use with a vapor holder, which can extend their capacity due to terminal growth or implementation of Stage I vapor recovery.

The second type of burner we build is a vapor recovery unit tail gas Burner. The RAN Eng Vapor Recovery Burner, processes VRU tail gas emissions as fuel. By using Maxon air heating burners, combustion is of high efficiency without time at temperature. Such burners have no assist gas cost required by time at temperature fuel burning incineration units. The units are generally small, 2 - 6M Btuh systems, and their operating and maintenance costs are very low. We use these burners with RAN Eng Vapor Recovery Systems; they can be used with other absorption and refrigeration units to meet 10mg/l.

The third type of burner is a Recovery / Direct Burner. These Burners have a high Btu turndown ratio; this allows them to efficiently burn saturated vapor or the exhaust from a 1- or 2- Stage VR Unit (2M btuh- 40M btuh typical). These RD Burners can burn low btu VRU tail gas directly and still burn vapor directly from the Equalizer / Vapor Holder. This gives you another way to process the vapor if the Vapor Recovery Unit fails, or it is taken off line for maintenance.

The fourth type of burner is our 1,100 cfm Portable Combustion System, which repeatedly tests at 2 mg/l without use of external fuel gas. This system is used when a terminal must replace their existing vapor recovery unit for maintenance or repair. The system is mounted on a 50’ Dual Axle, Expandable, Drop Deck Trailer. The 4,000 gallon, aluminum, DOT equalizer tank is separated from the burner skid by 10’, as shown, during operation. The system uses 10” inlet vapor hose, for connection to the rack vapor manifold. The system needs a 100 Amp, 480VAC main power supply, which is connected to the unit using an external power cord. The unit can operate using terminal rack switches or solely by sensing vapor manifold pressure. The system utilizes two 25 lb. Propane tanks (provided), for about one week worth of pilot gas. We currently have 3 units in operation with Marathon Ashland Petroleum.
