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.

A method for refurbishing a pre-stressed concrete cylinder pipe (PCCP) comprises removing concrete from an existing inner surface of the PCCP at each end thereof to expose a metal core, cleaning the exposed metal core and depositing filler over the exposed metal core at each end of the PCCP to a thickness wherein the filler is substantially flush with the existing inner surface. One or more layers of carbon fibre reinforced polymer (CFRP) liner are applied to the existing inner surface of the PCCP and to the filler at each end of the PCCP. Each layer of CFRP liner conforms to the inner surface of the PCCP and the filler and remains substantially cylindrical with substantially constant diameter along a length of the PCCP with substantially unbent cylindrical ends. After curing all layer(s) of CFRP liner, each terminus of the layer(s) of CFRP liner is sealed.

The disclosure relates to adapters, systems, and methods to connect a metal component and a ceramic component. The systems and methods generally include a metal header, a header seal and a zirconia toughened alumina (ZTA) header. The adapters, systems, and methods can further include a glaze and/or a palladium (Pd) or Pd-alloy coated membrane deposited on the ceramic component.

An assembly includes a first tube. The first tube includes a first end configured to receive a second tube. The second tube includes a first end configured to slidably translate into the first end of the first tube and to receive an insert. The insert is configured to be disposed within a first portion of the second tube that is near the first end of the second tube. The first tube, the second tube, and the insert form a seal. The coefficient of thermal expansion (CTE) of the first tube is similar to the CTE of the insert and different from the CTE of the second tube.
