Koch (pronounced "coke") Industries is the real thing, one of the largest (if not the largest) private companies in the US. Koch's operations are diverse, including refining and chemicals, process and pollution control equipment, and technologies; fibers and polymers; commodity and financial trading; and forest and consumer products (led by Georgia-Pacific). Its Flint Hills Resources subsidiary owns three refineries that together process more than 800,000 barrels of crude oil daily. Koch operates crude gathering systems and pipelines across North America as well as cattle ranches with more than 15,000 head of cattle in Kansas, Montana, and Texas. Brothers Charles and David Koch control the company.
