The sdcard is actually flash memory i believe and no its non removable. You rather buy the whole motherboard from 32gb version and replace it with yours since replacing only the flash memory is pretty hard and if you have accidently bought an empty flash memory then you still cant do anything.
The only way to expand your 16gb is to use an sdcard reader like meenova and an kernel which also have support for the sdcard thing to automatically mount it etc so you can use it like an normal micro sdcard in the most other phones.
