In 1998, Ratcliffe founded INEOS and the company has gone on to hand him his riches.
Speaking about his chemicals company, he told The Times: "We'd look at businesses that were unfashionable or unsexy, facilities owned by large corporations where you'd know they would be sloppy with the fixed costs.
"We'd run them a bit better, reduce the costs, make them busy, and over the cycle they are very profitable."
20 years after beginning his company, Ratcliffe was knighted by the Queen for his services to business and investment.

Earlier this year, INEOS' bid for United become public as a spokesperson said: "We have formally put ourselves into the process".
Ratcliffe's business was the first to make their interest in the takeover known with a battle looking set to ensue.
He has reportedly been working with two investment banks in Goldman Sachs and JP Morgan who are prepared to help out with his offer by providing loans and bonds.
