Multi-Stream Multi-Channel Process and Apparatus

An apparatus, comprising:

• a first section and a second section in combination;
• the first section comprising:
• a first first section millichannel;
• and
• a second first section millichannel;
• the second section comprising:
• a first second section millichannel in fluid communication with the first first section millichannel;
• a second second section millichannel in fluid communication with the second first section millichannel;
• and
• a third second section millichannel in fluid communication with the second second section millichannel.

A process, comprising:

• (a) distributing a first inlet stream into a plurality of first millichannels, thereby forming a plurality of first inlet streams;
• (b) distributing a second inlet stream into a plurality of second millichannels, thereby forming a plurality of second inlet streams;
• (c) distributing a third inlet stream into a plurality of third millichannels, thereby forming a plurality of third inlet streams;
• (d) contacting the plurality of second inlet streams and the plurality of third inlet streams, wherein at least one chemical reaction is effected, thereby forming a plurality of second outlet streams;
• (e) transferring heat between the plurality of first inlet streams and the at least one chemical reaction, thereby forming a plurality of first outlet streams;
• and
• (f) transferring heat between the plurality of first inlet streams and the plurality of first outlet streams.
