PROCESS Worldwide brings to you the ‘Top 10 plant engineering projects of September 2025’ from all over the world. Right from Evonik launching its world-scale alkoxides production facility in Singapore to Clariant supplying catalysts for the world’s largest electric steam methane reformer, find out all the projects making headlines here.

The German Federal Ministry for Economic Affairs and Climate Action has approved funding to BASF for developing the world’s largest industrial heat pump for CO2-free steam generation at its Ludwigshafen site in Germany. The heat pump is expected to reduce greenhouse gas emissions by up to 98 % at the site.

Using a dry-compressing screw vacuum pump in a casting machine significantly reduces the maintenance and operating costs of the vacuum system. Comparing the annual operating costs of an oil-lubricated system with those of a dry-compressing vacuum system of similar performance results in significant cost savings, shares Leybold.

Matheson Tri-Gas has awarded a significant contract to Nikkiso Clean Energy & Industrial Gases Group to develop an air separation unit in Las Vegas, Nevada. The new project is expected to produce oxygen, nitrogen, and argon in order to meet the increasing demand for liquid gases in the medical, fabrication, construction, and food processing industries across Nevada, California, Utah, and Arizona.

John Crane has introduced a next generation mechanical seal called Type 8628VL. The mechanical seal has been engineered to maintain sealing integrity in multiphase ethane and ethylene pipelines within the oil and gas industry.

Claimed to be one of the world’s largest industrial heat pumps for CO2-free steam generation, BASF and GIG Karasek have recently broken ground for the project at BASF’s Ludwigshafen site in Germany.

Sulzer has signed an agreement with Highview Power to deliver eight molten salt pumps, five cryopumps and a selection of auxiliary services. The partnership aims to unlock long-duration energy storage at Highview Power’s new facility at Carrington, Manchester, and at other future facilities across the UK.

Metso’s groundbreaking Life Cycle Services model is a new scalable approach that reflects the shift toward outcome-based partnerships and performance-driven business models, while addressing customers’ different levels of support requirements.

KSB Group has introduced size 150 of its newly developed Multitec Plus type series. Specially designed for transporting drinking water, the pump aims at offering optimum hydraulic efficiency.

Leybold has now expanded its range of oil diffusion pumps to include the Diffvac DP and Diffvac OB series. The new Diffvac DP series offers energy efficiency, robustness and uninterrupted operating times while the OB series is particularly suitable for industrial high vacuum applications.
