System and method for converting light hydrocarbons to heavier hydrocarbons with improved water disposal

This invention describes a way to turn light hydrocarbons, like natural gas, into heavier fuels using a chemical reaction. A significant part of the invention focuses on cleaning the dirty water produced during this process. It does this by first concentrating the contaminants in a special column, and then using a stream of light hydrocarbons from the process itself to strip those contaminants out in a second column.

Why it matters: Environmental regulations for industrial wastewater disposal have become significantly stricter since 2000, increasing the value of efficient, integrated contaminant removal systems. The drive for process efficiency and sustainability also makes utilizing internal streams, like tail gas for stripping, more attractive.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedChemical reactors, multiple columns, gas handling equipment.
