Gas Liquids Engineering (GLE) is currently carrying out detailed engineering on a major carbon capture project at the Marquis Industrial Complex, near Hennepin, USA, at the largest dry-grind ethanol plant in the world. The project will capture 2.25 Million Metric Tonnes per year of biogenic CO2 from the batch fermentation processes of the facility. The CO2 from the existing fermentation scrubbers will be captured and piped to a 7.4 MW (10000 HP) compression system, consisting of an electrically driven, integrally geared, multistage centrifugal compressor. The CO2 will then be dehydrated using a 230 MMBtu/h triethylene glycol (TEG) dehydration system, prior to being piped through a 10” piping system to a new on-site sequestration well. The high pressure sequestration system will operate at approximately 10300 kPag (1500 psig), permanently sequestering CO2 in a geological formation located deep below the facility.
GLE’s scope of work has included the process, mechanical, civil, instrumentation, drafting, procurement, and project management services on the project. Equipment procurement is well underway, with an anticipated startup in late 2024.
