This Question contains a variety of answers that assisted me when I was building a standalone PyQGIS script and repeatedly had the error no module named qgis and no module named processing.

The answer I used is the one discussing the .bat file that triggers the standalone and connects to the processing toolbox.

The module is called processing in small letters

import processing

or

from processing import Processing

Also have a look at this complete example and excellent answer https://gis.stackexchange.com/a/131809/9839
