Subsequent Events [Abstract]
Subsequent Event	SUBSEQUENT EVENTIn July 2024, we entered into an agreement to sell our liquefied natural gas process technology and equipment business to Honeywell International Inc. for approximately $1.8 billion in an all-cash transaction. We expect to close the sale before the end of calendar year 2024, subject to the satisfaction or waiver of customary closing conditions, including the receipt of certain regulatory approvals. The decision to divest this business reflects our continued focus on growing and efficiently operating our core industrial gas business while executing projects that will provide world-scale clean hydrogen. The expected sale does not qualify for presentation as a discontinued operation as it does not represent a strategic shift in our operations.
