Propane (home use)

French specialty chemicals company; world's leading ethyl mercaptan producer. Beaumont, TX is the sole US production site for propane odorant ethyl mercaptan. In 2023, Arkema produced 11,000+ MT of mercaptans total, supplying gas odorants to 200+ distribution companies globally across Europe, North America, and Asia-Pacific. Arkema also produces mercaptan blends (SPOTLEAK, VIGILEAK) for natural gas odorization. Separate from mercaptans, Arkema operates specialty polymers, adhesives, and coating resin businesses. Also notable for the September 2017 Arkema Crosby TX peroxide plant fire — a different Arkema facility near Houston that caught fire during Hurricane Harvey when refrigeration failed, causing explosion and evacuation.

Dominant US propane cylinder manufacturer (~40% US market); produces full range of DOT/ASME-spec propane vessels from 1-lb portable to 1,000-gallon residential tanks. Manufacturing in Monroe OH (primary cylinders plant), Westerville OH, and other US locations. Also manufactures industrial gas cylinders (welding oxygen, acetylene), military high-pressure vessels, and medical oxygen tanks from the same pressurized vessel manufacturing platform. 2021 steel shortage caused 23-week lead times for all tank sizes (per Worthington sales director to NPGA). Recalled propane exchange tanks in 2023-2024 per CPSC notice. Worthington spun off its steel processing business in 2023 as Worthington Steel — now Worthington Enterprises focuses on building products including cylinders.

Largest US midstream operator; holds the largest LPG/NGL salt cavern storage position at Mont Belvieu, Texas. Enterprise's Mont Belvieu complex includes dozens of solution-mined salt cavern storage cells in the Barbers Hill salt dome, holding hundreds of millions of barrels of NGL storage capacity. Also operates fractionation, pipelines, and marine export terminals at the same complex. Mont Belvieu's propane price is the global benchmark — Enterprise, as the largest storage operator, holds significant pricing influence over seasonal propane markets. Also operates the LOOP (Louisiana Offshore Oil Port) deepwater crude oil terminal.

Heavy-truck maker (Kenworth, Peterbilt, DAF); chassis for propane bobtails and tankers.

Major US petrochemical company (JV between Chevron and Phillips 66); produces ethyl mercaptan at Borger, TX and Tessenderlo, Belgium (Tessenderlo expanded 65% in 2017). Ethyl mercaptan is part of a broader organosulfur chemicals portfolio including methyl mercaptan, DMDS (dimethyl disulfide), and specialty sulfur chemicals. Applications: gas odorization, polymer modifiers, agricultural chemicals, pharmaceuticals, water purification, and lubricant additives. Tessenderlo capacity expansion noted by Hydrocarbon Processing (2017). Also the world's leading polyethylene producer (Cedar Bayou, TX cracker complex).

Privately held US industrial manufacturer; parent of Manchester Tank & Equipment Co. Manchester Tank (founded 1946, Franklin TN HQ) manufactures steel and aluminum DOT cylinders and ASME pressure vessels. Facilities: Bedford IN, Crossville TN, Elkhart IN, Quincy IL, Campbellsville KY (new), Echuca Australia, Chile (two locations). Makes residential propane tanks 120-1,000 gallons and DOT cylinders. McWane also manufactures water and sewer pipe products, fire hydrants, and other municipal infrastructure — Manchester Tank is one of several diverse industrial manufacturing businesses. New Campbellsville KY facility opened to serve growing demand for residential propane tanks.

Major US midstream partnership; holds NGL and LPG salt cavern storage at Mont Belvieu (Lone Star NGL/Energy Transfer). Also operates Mariner East pipeline system connecting Appalachian NGLs to Marcus Hook PA export terminal. Marcus Hook exports ~20% of US propane, requiring coordinated storage drawdown from Mont Belvieu caverns. Diverse midstream footprint: natural gas, crude oil (Dakota Access), NGLs, and refined products.

Largest US midstream MLP; operates the Enterprise Hydrocarbons Terminal (EHT) on Houston Ship Channel -- the largest LPG export terminal in the US and one of the largest in the world. 7 deepwater ship docks; expanding by 300,000 b/d by end of 2026. US propane exports have grown every year since 2007; Enterprise handles a dominant share of US LPG export volume.

Major NGL midstream operator; holds significant NGL salt cavern storage at both Mont Belvieu, TX and Conway, KS (the two primary US NGL storage hubs). Conway, KS is the secondary US propane price benchmark hub (for Midcontinent propane) — ONEOK is the dominant storage and fractionation operator at Conway. Total NGL fractionation capacity 1M+ bpd. Acquired Magellan Midstream Partners (2023) for $18.8B, adding refined products infrastructure.

Builds propane/NH3 bobtail trucks, transports, and fuel/propane dispensing equipment.

Major NGL midstream operator; holds NGL salt cavern storage at Mont Belvieu, TX. Targa's Grand Prix NGL pipeline brings Permian Basin NGL production to Mont Belvieu for fractionation and storage. 518,000 b/d fractionation capacity. Cedar Bayou Fractionator at Baytown TX was flooded during Hurricane Harvey 2017. The integrated storage-fractionation-export complex at Mont Belvieu represents the core of Targa's infrastructure value.

State-owned energy company of Qatar; world's largest LNG producer (77M MT/year capacity, targeting 142 MT/year by 2029-30). North Field is one of the world's largest natural gas reserves. Qatar produces elemental sulfur as a byproduct of gas processing and LNG operations. Qatar's sulfur exports are approximately 0.18M MT/year (per one market data point), though Qatar's Hormuz exposure makes it a key transit chokepoint for regional sulfur flows even if its own production is modest relative to Saudi Arabia or Canada.

German specialty chemicals company; major producer of methyl mercaptan (used in methionine synthesis for animal feed) and other organosulfur chemicals. Also produces specialty sulfur chemicals including mercaptan blends used in gas odorization. Evonik's organosulfur chemicals are primarily focused on methionine production (world's largest DL-methionine producer under 'EVONIK MetAMINO' brand) — methionine is the most important amino acid supplement for poultry and aquaculture. Same mercaptan chemistry used in safety odorants also underpins the global animal feed amino acid supply chain.

Fabricator of propane/NH3 bobtail truck bodies, transport trailers and pressure vessels.

World's largest oil company by production. LPG is an associated byproduct of Saudi crude oil production and refining; exported via Ju'aymah LPG terminal at Ras Tanura (Eastern Province) and Yanbu (Red Sea). Saudi Arabia accounts for ~7-8% of global seaborne LPG exports (WLPGA 2023).

World's largest industrial gas company; provides gas odorant distribution and blending services globally including ethyl mercaptan. Air Liquide distributes and markets mercaptan gas odorants to LPG and natural gas utilities. Also a leading producer of industrial gases (oxygen, nitrogen, hydrogen, noble gases) for healthcare, industry, and energy. Air Liquide is listed among the top ethyl mercaptan market participants; primarily as a specialty gas blender/distributor rather than a primary mercaptan chemical producer.

One of the largest energy infrastructure companies in North America; holds natural gas and NGL storage assets including salt cavern storage. Kinder Morgan's Products Pipelines segment operates refined products and NGL pipelines with associated storage. Also a leading operator of liquefied natural gas (LNG) facilities and CO2 pipelines for enhanced oil recovery. Less dominant in LPG salt cavern storage specifically vs. Enterprise/Energy Transfer/ONEOK, but holds meaningful storage capacity.

Abu Dhabi's state oil company. LPG produced at Ruwais industrial complex (largest refinery in Middle East) and exported via Abu Dhabi. UAE LPG exports fluctuated significantly -- down 58% in 2024 per WLPGA. ADNOC also supplies LPG domestically for residential cooking.
