Abstract
A system for producing chemicals, such as, ethylene or gasoline, at high temperature (above 1100 degrees C.) having a feedstock source. The system includes a chemical conversion portion connected with the feedstock source to receive feedstock and convert the feedstock to ethylene or gasoline. The conversion portion includes a coil array and a furnace that heats the feedstock to temperatures in excess of 1100° C. or 1200° C. or even 1250° C. or even 1300° C. or even 1400° C. A method for producing chemicals, such as ethylene or gasoline, at high temperature.
Claims14
A system for producing ethylene or gasoline comprising:
- a feedstock source;
- a chemical conversion portion connected with the feedstock source to receive feedstock and convert the feedstock to ethylene or gasoline, the conversion portion including a coil array and a furnace that heats the feedstock to temperatures in excess of 1100° C., the coil array having a plurality of coils, each coil having a right top portion made of super alloy that connects with the source to receive feedstock, a right oxidation protected tungsten coupling that is attached outside the furnace to the right top portion and forms a helium gas tight seal with the right top portion, a right bottom portion made of silicon carbide that is attached outside the furnace to the right oxidation protected tungsten coupling and forms a helium gas tight seal with the right oxidation protected tungsten coupling, a base made of silicon carbide that is attached to the right bottom portion and forms a helium gas tight seal with the right bottom portion, a left bottom portion made of silicon carbide that is attached to the base and forms a helium gas tight seal with the base, a left oxidation protected tungsten coupling that is attached outside the furnace to the left bottom portion and forms a helium gas tight seal with the left bottom portion, and a left top portion made of super alloy that is attached to the left oxidation protected tungsten coupling outside the furnace and forms a helium gas tight seal with the left oxidation protected tungsten coupling, the right top portion and the right oxidation protected tungsten coupling and the right bottom portion and the base and the left bottom portion and the left oxidation protected tungsten coupling and the left top portion being hollow and defining a channel through which feedstock flows and is heated by the furnace to produce ethylene from the feedstock, the furnace heating the left bottom portion and the base and the right bottom portion to temperatures in excess of 1100° C.;
- and
- a reservoir connected with the left top portion of each coil to receive ethylene or gasoline from the left top portion of each coil.
1 more element
A method for producing ethylene or gasoline comprising the steps of:
- flowing feedstock from a feedstock source to a chemical conversion portion connected with the feedstock source to receive feedstock and convert the feedstock to ethylene or gasoline, the conversion portion including a coil array and a furnace that heats the feedstock to temperatures in excess of 1100° C., the coil array having a plurality of coils, each coil having a right top portion made of super alloy that connects with the source to receive feedstock, a right oxidation protected tungsten coupling that is attached outside the furnace to the right top portion and forms a helium gas tight seal with the right top portion, a right bottom portion made of silicon carbide that is attached outside the furnace to the right oxidation protected tungsten coupling and forms a helium gas tight seal with the right oxidation protected tungsten coupling, a base made of silicon carbide that is attached to the right bottom portion and forms a helium gas tight seal with the right bottom portion, a left bottom portion made of silicon carbide that is attached to the base and forms a helium gas tight seal with the base, a left oxidation protected tungsten coupling that is attached outside the furnace to the left bottom portion and forms a helium gas tight seal with the left bottom portion, and a left top portion made of super alloy that is attached to the left oxidation protected tungsten coupling outside the furnace and forms a helium gas tight seal with the left oxidation protected tungsten coupling, the right top portion and the right oxidation protected tungsten coupling and the right bottom portion and the base and the left bottom portion and the left oxidation protected tungsten coupling and the left top portion being hollow and defining a channel through which feedstock flows and is heated by the furnace to produce ethylene or gasoline from the feedstock, the furnace heating the left bottom portion and the base and the right bottom portion to temperatures in excess of 1100° C.;
- and
- receiving ethylene or gasoline at a reservoir from the left top portion of each coil.
A pipe structure for use at high temperatures:
- a first tube of silicon carbide extending in a first direction;
- and a second tube of silicon carbide extending from the first tube, wherein the first and second tubes are bonded with a helium leak tight seal.
