What does NGL Energy sell?

Could you elaborate on the products and services offered by NGL Energy? I'm curious to understand the CORE business operations and what specific commodities or energy sources they specialize in. Do they primarily focus on natural gas liquids, or do they have a broader portfolio? Additionally, how do they position themselves in the energy market and what makes them stand out from their competitors? I'd appreciate a concise yet comprehensive overview of NGL Energy's business operations and their products and services.
