PraxairEdit
Praxair, Inc. was one of the world’s leading producers and distributors of industrial gases, a sector essential to modern manufacturing, healthcare, electronics, and energy. The company built a global network of air separation plants, gas processing facilities, distribution operations, and engineering services to supply gases such as oxygen, nitrogen, argon, hydrogen, helium, and carbon dioxide, along with specialty gas mixtures and related equipment. Praxair’s activities touched a broad swath of industry—from steelmaking and chemicals to the burgeoning semiconductor and healthcare sectors—making it a central player in the global industrial gas landscape. In 2018, Praxair merged with Linde AG to form Linde plc, reshaping the competitive dynamics of the sector and creating a company with a truly global footprint. Praxair’s former operations and brand elements now live on as part of that larger enterprise.
Praxair, Inc. and its successor operations occupied a prominent position in the world market for industrial gases. The company’s offerings ranged from common industrial gases used in metal fabrication and food processing to highly specialized gases and gas mixtures tailored for electronics fabrication, pharmaceuticals, and healthcare. Core technologies included cryogenic air separation, which yields oxygen, nitrogen, and argon from ambient air, and advanced gas handling, purification, and delivery systems. The portfolio was augmented by engineering services for gas-on-goods integrations and by a portfolio of coatings and surface-treated materials through the division known as Praxair Surface Technologies.
The corporate history of Praxair is characterized by growth through expansion and strategic acquisitions, integrating regional gas suppliers and building a diversified, global supply chain. The firm established a substantial footprint in North America and extended its reach into Europe, Asia, and other regions, aligning with the broader industry trend toward large, integrated gas companies capable of serving multiple end markets with scale and reliability. In the market for industrial gases, Praxair stood alongside other global leaders such as Air Liquide and Linde plc, forming a triad of industry giants that shape product standards, pricing, and technology development.
History
Praxair’s emergence as a major force in industrial gases reflects the broader consolidation in the sector during the late 20th and early 21st centuries. The company grew out of a lineage of regional gas producers and distributors that supplied atmospheric and process gases for manufacturing, processing, and healthcare uses. Over time, Praxair expanded through acquisitions, technology investments, and the development of a vertically integrated supply chain that could produce, purify, store, transport, and dispense gases on a global scale. This approach enabled Praxair to offer comprehensive gas solutions—from standard cylinder gases for welding to large-scale industrial gas plants and turnkey gas processes for customers in steel, chemical processing, and electronics.
A turning point in the corporate arc occurred in 2018, when Praxair agreed to merge with Linde AG, a major German industrial gas company, in a deal that created Linde plc. The merger received approvals from competition authorities around the world, including the Federal Trade Commission in the United States and the European Commission in the European Union, often subject to conditions designed to preserve competition in specific markets. The consolidated entity positioned Linde plc as the largest industrial gas company by sales and a central supplier to industries worldwide, while also attracting ongoing scrutiny from policymakers concerned about market concentration and pricing dynamics in certain regional markets.

The practice of on-site gas generation and automated supply chains has been a hallmark of the industrial gases sector, enabling customers to minimize downtime and optimize process performance.
Corporate affairs and regulatory environment
The industrial gases industry operates at the intersection of manufacturing efficiency, safety, environmental stewardship, and competition policy. Praxair’s operations were governed by a range of regulatory regimes intended to ensure safety, air and water quality, occupational standards, and fair competition. In the United States, regulatory oversight comes from agencies such as the Occupational Safety and Health Administration and the Environmental Protection Agency, with further scrutiny from state and local authorities. In Europe, regulators and competition authorities, including the European Commission, evaluated mergers and market practices to protect consumer welfare and maintain competitive markets. The 2018 merger of Praxair with Linde AG is a primary example of how such deals are reviewed, sometimes resulting in divestitures or behavioral commitments to address competition concerns.
From a corporate governance perspective, Praxair operated as a major industrial player subject to the market discipline of corporate finance, capital investment, and return policies. The combination with Linde AG ultimately led to the formation of Linde plc, a company that inherited Praxair’s asset base, customer relationships, and geographic reach while integrating with Linde’s existing assets and management structure. The new entity continued to navigate global trade, regulatory compliance, and environmental considerations, including emissions reduction, energy efficiency, and responsible sourcing.
Controversies and debates
A key debate surrounding Praxair and its successor remains rooted in the broader questions about scale in strategic industries. Supporters of large-scale, vertically integrated industrial gas companies argue that the scale enables: - Lower costs and improved reliability through optimized logistics and supply chain resilience. - Greater investment capacity in safety, process technology, and environmental performance. - Enhanced ability to serve multinational customers with consistent standards across borders.
Critics, including some policymakers, customers, and industry observers, worry that concentrated market power in a few global players could reduce competition in regional markets, potentially limiting price competition and customer choice. In the case of the Linde-Praxair merger, regulators in multiple jurisdictions examined whether the combined entity would unduly lessen competition in certain market segments, such as gas supply for steelmaking and specialized gas services. The eventual approvals often included divestitures or commitments designed to preserve competitive options for customers in specific locales. The debate mirrors broader discussions about how to balance efficiency and innovation with the need to maintain competitive markets.
From a pro-capital, right-of-center perspective, the argument in favor of the Praxair-Linde merger centers on: - Encouraging investment in advanced manufacturing technologies and energy efficiency, which can yield lower operating costs and improved productivity for customers. - Maintaining global competitiveness by allowing a large, well-capitalized supplier to fund R&D in areas such as gas purification, storage, and process optimization. - Letting supply chains evolve toward more integrated, end-to-end gas solutions that reduce downtime and support high-uptime manufacturing environments.
Critics often focus on the potential for price consolidation to squeeze smaller competitors or regional suppliers. Proponents would counter that robust regulatory approvals and, where applicable, divestitures or behavioral remedies help preserve competition while enabling the efficiencies and reliability that large-scale producers can provide. In the broader policy discourse, supporters underscore the importance of a strong manufacturing base and the role that reliable industrial gases play in advanced industries, while acknowledging the need for sensible regulatory frameworks to prevent abuses of market power.
Sustainability and environmental considerations also feature in the controversy landscape. Critics of large industrial operations emphasize energy intensity, emissions, and the environmental footprint of gas production and distribution. Proponents argue that high-purity gases and optimized processes reduce emissions and energy use in downstream manufacturing (for example, using nitrogen and oxygen in steelmaking can improve energy efficiency). The dialog in this area often centers on measurement, disclosure, and the development of best practices for environmental stewardship within a framework that still prizes competitive markets and innovation.
