Elessent Clean Technologies (Elessent) has announced that it is implementing a global price increase of $2.50 per liter for its cesium-promoted MECS® sulfuric acid catalyst products. The company attributes this adjustment to ongoing and evolving market conditions that continue to influence production costs, supply chains, and raw material availability. In addition to the base price increase, customers may experience supplemental charges related to freight, expedited or near-term delivery, and certain specialty catalyst grades. These additional fees will be applied as necessary based on order requirements and regional logistics. Except where existing long-term agreements dictate otherwise, the revised pricing structure goes into effect immediately, making the announcement relevant for all new orders moving forward.
For nearly a century, the sulfuric acid industry has relied on the performance, stability, and durability of MECS® catalyst products. First introduced in 1925, the MECS® catalyst line quickly became known for its ability to convert sulfur dioxide (SO₂) to sulfur trioxide (SO₃) with remarkable reliability and economic efficiency—two qualities that are essential for operators of sulfuric acid plants.
Over the decades, the MECS® name has become synonymous with innovation in catalysis and sulfuric acid production technology. As a global leader in both catalyst manufacturing and sulfuric acid process technology, Elessent continues to support producers worldwide with solutions that increase plant capacity, elevate energy efficiency, and reduce SO₂ emissions, all while maintaining the highest standards of operating performance.
The MECS® sulfuric acid technology platform has played a foundational role in numerous major industries for more than one hundred years. From phosphate fertilizer production to non-ferrous metals processing—such as leaching, smelting, and refining—the technology is embedded in many critical industrial operations. It also serves essential functions within the oil refining industry and a broad range of general chemical manufacturing processes. Across all these sectors, operators turn to MECS® solutions to maintain consistent production rates, meet stringent regulatory requirements, and achieve long-term operational stability.
One of the most distinctive aspects of the MECS® technology portfolio is its history of breakthrough engineering solutions, many of which have reshaped both the performance and cost structure of sulfuric acid operations. Elessent’s MECS® heat recovery systems (HRS™), for example, are designed to help operators capture and reuse thermal energy generated during acid production. By recovering this energy, plants can significantly reduce fuel consumption and operational expenses, while simultaneously lowering emissions associated with energy use. The HRS™ technology is widely recognized for enhancing overall plant efficiency and contributing to sustainability objectives.
Another notable technology within the MECS® family is the MECS® SolvR® regenerative SO₂ scrubbing system. SolvR® provides an advanced approach to removing SO₂ from process gas streams, allowing operators to meet stringent environmental regulations while maintaining high production output. The system is engineered for minimal waste generation and offers a closed-loop design that optimizes resource utilization. With tightening emissions standards around the world, SolvR® has become an important tool for customers that need to reduce their environmental footprint without compromising operational productivity.
The MECS® MAX3™ technology represents an additional milestone in sulfuric acid production innovation. MAX3™ is designed to increase throughput, lower operating costs, and further minimize emissions across the production process. Its integration into plant operations helps improve conversion efficiency and enhances the overall economics of sulfuric acid manufacturing. By providing these performance advantages, MAX3™ technology supports producers in meeting both market demand and sustainability goals.
Beyond these core technologies, the broader MECS® portfolio also includes a suite of specialty products engineered for the most challenging operational environments. Brink® mist eliminators, for example, are designed to remove fine acid mist droplets from process gas streams, thereby improving product quality and protecting downstream equipment. DynaWave® scrubbers deliver robust gas scrubbing performance and are well-known for their ability to handle tough applications with high particulate loading or corrosive environments.
Additionally, ZeCor® corrosion-resistant alloy products offer exceptional durability in harsh sulfuric acid conditions, providing long service life and reduced maintenance requirements. MECS® acid coolers round out the portfolio, supplying reliable cooling performance essential for efficient plant operation. Together, these products form an integrated ecosystem of technologies that enhance plant performance, safety, longevity, and economic viability.
Elessent Clean Technologies is responsible for the global licensing and marketing of the MECS® technology platform. With more than 1,000 sulfuric acid plant licenses and projects worldwide, MECS® stands as the most widely adopted sulfuric acid production technology in the world. This extensive track record reflects the trust producers place in MECS® systems and the consistent value delivered across diverse industrial applications.
Elessent’s commitment extends far beyond initial technology deployment; the company emphasizes long-term customer satisfaction and provides ongoing technical support throughout the entire lifecycle of customer assets. Through continuous improvement initiatives, technical service programs, and investment in research and development, Elessent aims to ensure that operators can depend on MECS® technologies for decades of stable performance.
As Elessent implements the updated pricing for its cesium-promoted MECS® sulfuric acid catalyst products, the company reiterates its dedication to supporting customers amid shifting market conditions. While the price adjustment reflects the economic realities of production and supply chain pressures, Elessent remains focused on providing technologies and services that offer long-term value, high efficiency, and operational reliability.
