UOP LLC, formerly known as Universal Oil Products, is a multi-national company developing and delivering technology to the petroleum refining, gas processing, petrochemical production, and major manufacturing industries.

The company's roots date back to 1914, when the revolutionary Dubbs thermal cracking process created the technological foundation for today's modern refining industry. In the ensuing decades, UOP engineers generated thousands of patents, leading to important advances in process technology, profitability consultation, and equipment design.

UOP was founded in 1914 to exploit the market potential of patents held by inventors Jesse A. Dubbs and his son, Carbon Petroleum (C. P.) Dubbs. Perhaps because he was born in Pennsylvania oil country, Jesse Dubbs was enamored with the oil business. He even named his son Carbon after one of the elemental constituents of oil. Later, Carbon added the P. to make his name "euphonious," he said. People started calling him "Petroleum" for fun, and the name stuck. C. P.'s son and grandson were also named Carbon, but each had a different middle initial.
