摘要： A cracking furnace for the pyrolysis heating of an organic feedstock includes a heating section and at least one convection section. In one embodiment the furnace includes first and second convection sections positioned along opposite sides of the heating section. The openings for admitting flue gas to the convection sections can be at the top or the bottom of the heating section. In another embodiment the furnace includes a plurality of passageways for the communication of flue gas from the heating section to the convection section. The passageways can be positioned at the top or the bottom of the heating section. The passageways provide a more even flow of flue gas through the heating section by preventing recirculation of the flue gas within the heating chamber.

摘要： A parallel flow reactor for the selective catalytic reduction of nitrogen oxide in a gas stream includes a shell enclosing an interior space in which is located a plurality of substantially parallel planar catalyst beds, each containing a catalyst for the selective conversion of NOx. Deflectors in the spaces between the catalyst beds direct the flow of gas through the beds. An injector upstream of the catalyst beds introduces a reducing agent such as ammonia into the inlet gas stream. The catalyst bed can include monolith or microengineered catalyst.

摘要： A pyrolysis heater particularly for the cracking of hydrocarbons in the production of olefins has a burner arrangement in the firebox which directly heats the hearth of the firebox such that it becomes a radiant surface. This improves the heat flux in the lower portion of the firebox and produces a more uniform vertical heat flux profile over the firebox elevation. The base burners may fire horizontally across the hearth or may comprise porous ceramic burners as a part of the hearth. The base burners operate along with vertically firing hearth burners and optional wall burners in the upper portion of the firebox.

摘要： A pyrolysis heater particularly for the cracking of hydrocarbons in the production of olefins has a burner arrangement in the firebox which includes staged combustion low NOx hearth burners firing upwardly in the firebox adjacent to the walls. Wall stabilizing gas fuel injection tips, located at an elevation above the hearth burners, inject fuel upwardly between the walls and the flame from the hearth burners. This prevents rollover of the flame onto the process heater coil and overheating of the coil.

摘要： A radial flow gas phase reactor for the selective catalytic reduction of nitrogen oxide in a gas stream includes a shell enclosing an interior space in which is located at least one catalyst bed containing a catalyst for the selective conversion of NOx. A deflector directs the flow of gas radially through the bed. An injector upstream of the catalyst introduces a reducing agent such as ammonia into the inlet gas stream. The catalyst bed can include particulate, monolith, or microengineered catalyst.

摘要： A pyrolysis heater has the inlet sections of the process coils grouped together and the outlet sections of these same process coils also grouped together. High heat liberation hearth burners are located adjacent to the inlet sections of the coils and lower heat liberation burners are located adjacent to the outlet sections. The secondary fuel tips of the burners are inclined toward the adjacent heater wall. The high heat liberation hearth burners adjacent to the inlet coils are arranged in spaced apart pairs with the secondary burner tips of each of the pair being inclined toward the other burner of the pair.
