It may have already been discussed in the past but let me share my understanding of the various technologies available for small to mid-scale.

OSMR - developed by LNGL as well all know. No plants yet in operation
IPSMR - Chart Industries. This is the technology Venture Global is going with. Chart has small plants in operation and also is a fabricator of cold boxes and heat exchangers. You can find more details at their website
Prico - Black & Veatch. Multiple units in operation sizes range from small scale and up. I believe Jordan Cove is going to be Prico process.
AP-SMR - Air Products. AP offers a small to mid-scale process in addition to their more widely know offering for large scale trains. They of course also manufacture critical equipment.

All these processes target to minimize equipment count, plot space and lend themselves to be constructed offsite in modules. Additionally I beleive LNGL uses ammonia as it's refrigerant and also focuses on heat recovery to keep energy costs down.
