How we know the date
Ussher's Annals (1650) gives 1912 BC (its year of the world 2092 c); ISBE's Old Testament chronology (1915) describes it without giving a year.

The sources, word for word
“2092. c. Anno decimo quarto Chedorlaomer cum confœderatis principibus, Amraphelo Shinaris, Arjoco Ellasaris et Tidale Gentium, junctis copiis adversus rebelles regulos expeditione suscepta, Raphæos, Zuzæos, Emæos, Choræos, incolas regionis quæ postea fuit Amalekitarum, et Emoræos primum percusserunt; deinde regulis Pentapolitanis in valle Siddimorum profligatis, Lotum captivum, simul cum omnibus facultatibus Sodomæ et Gomorrhæ, secum abduxerunt.”
“(3) Accepting the almost universal and well-grounded judgment that the Amraphel of Ge 14 is the famous Hammurabi of the 1st Babylonian Dynasty, we should have assistance in determining the date of his Biblical contemporary Abraham, if the opinions of scholars about the age of Hammurabi were not so divergent.”
