Overview
Hanson Engineering - Larned Amine Plant is an operational oil extraction facility in Larned, Kansas, USA. It processes natural gas to remove hydrogen sulfide and carbon dioxide, supporting regional energy production.
Hanson Engineering - Larned Amine Plant is an operational oil extraction facility located at 1293 70th Ave S1-T22S-R16W in Larned, Pawnee County, Kansas. The plant is situated in the central United States, an area with a long history of oil and gas production, particularly from the Anadarko Basin and Hugoton Field. As an amine plant, it plays a critical role in natural gas processing by removing acid gases such as hydrogen sulfide and carbon dioxide, making the gas suitable for pipeline transport and commercial use. The facility operates under the regulatory oversight of the U.S. Environmental Protection Agency (EPA) and the Kansas Department of Health and Environment. It is subject to the Clean Air Act (CAA) regulations, including the Refinery MACT standards for hazardous air pollutants, as well as state-level permitting for emissions and waste management. The plant's NAICS codes (211111, 211120, 211130) indicate activities related to crude petroleum and natural gas extraction, natural gas liquid extraction, and oil and gas field services. Typical amine plants in this region use chemical absorption processes with amines like monoethanolamine (MEA) to treat sour gas. The Larned Amine Plant contributes to the local economy by supporting the oil and gas supply chain in Kansas. Its operational status ensures continued processing of natural gas from nearby wells, reducing environmental impacts by removing sulfur compounds before combustion. The facility's location in a rural area minimizes population exposure, but standard safety protocols for handling flammable gases and amines are essential to prevent accidents and protect groundwater.
Environmental context
The plant is located in a semi-arid region of Kansas, where oil and gas extraction is a primary industry. The primary environmental concern for amine plants is the release of hydrogen sulfide, a toxic and corrosive gas, and the disposal of spent amine solutions. The facility must comply with EPA regulations under the Clean Air Act for emissions of sulfur dioxide and volatile organic compounds. Spills or leaks could impact local soil and groundwater, though the rural setting reduces immediate risks to populated areas.
