Abstract
The invention provides methods of making laminated devices (especially microchannel devices) in which plates are assembled and welded together. Unlike conventional microchannel devices, the inventive laminated devices can be made without brazing or diffusion bonding; thus providing significant advantages for manufacturing. Features such as expansion joints and external welded supports are also described. Laminated devices and methods of conducting unit operations in laminated devices are also described.
