KBR’s Reforming Exchanger System (KRES™) combines a KBR Reforming Exchanger with an autothermal reformer (ATR), working in parallel. This design is very attractive at sites where low cost oxygen is available. This design has the following advantages:
Lower capital cost
Lower emissions, averaging 56% reduction compared to a fired reformer design
Smaller plot space
Lower energy consumption than fired reformer design
Less steam export than fired reformer design
Faster and easier start-up and operation
KBR's KRES™ reforming exchanger system has been in commercial operation since 1994. View KRES™ Scheme. Feed and oxidant (air, enriched air, or oxygen) are preheated in a simple fired heater. The fuel for the heater may be low-value material such as fuel oil. Part of the heat for the reforming reaction is recovered from the reformer effluent in a KRES™ reforming exchanger. The exchanger contains reforming catalyst in the tubes.
KBR's well-proven autothermal reformer performs partial oxidation of light hydrocarbons.
KBR's waste heat boiler is a natural-circulation, water-tube, floating-head design. It has low capital and maintenance cost.
