HOUSTON, Sept 23 (Reuters) - Gas flow into the largest

U.S. liquefied natural gas (LNG) plant fell nearly 600 million

cubic feet on Tuesday from Monday, short of peak demand by 1.4

billion cubic feet (bcf), according to preliminary data from

financial firm LSEG.

Cheniere Energy's Sabine Pass plant in Texas, which can

pull over 5 bcf a day of natural gas to convert into LNG, was

down to 3.8 bcf from 4.4 bcf on Monday, suggesting at least one

of its processing plants, which are called trains, could be

offline, LSEG data showed.

The company did not immediately respond to a request for

comment.

Cheniere is the largest exporter of the superchilled gas in

the U.S. and played a key role in making the country the world's

largest LNG exporter.
