While politicians continuously debate whether the U.S. should export oil and natural gas, the export of natural-gas liquids such as propane and ethane is growing at an almost exponential rate. With the shale boom producing more of these hydrocarbons used for chemical feedstocks than this nation can consume, prices at historic lows, and the shift from oil-based to NGL-based chemical feedstocks in places like Europe and the Asia-Pacific, there couldn't be a more opportune time to export NGL. Investors who want to seriously look at NGL exports must consider two major players: Enterprise Products Partners (NYSE:EPD) and Navigator Holdings (NYSE:NVGS).

Tune into the video below to find out why Enterprise and Navigator are set up to be the best investments in the NGL export game and how the NGL boom has affected the direction of these two companies.
