BASF achieved a significant milestone with the arrival of a critical component for its industrial heat pump project at its Ludwigshafen facility. The 95-ton plate falling-film evaporator, one of the largest components of the system, was transported over several hundred kilometers via waterways from Schwedt on the Oder River to BASF’s main site. Subsequently, heavy-haul trucks moved the equipment across the plant to the construction site at the steam cracker, where installation is now underway.
Central Role of the Falling-Film Evaporator
The falling-film evaporator plays a crucial role in the heat pump system. Within this unit, oxygen-free steam is generated—an essential requirement for industrial applications. Once produced, the process steam is distributed through BASF’s integrated Verbund network, supplying energy efficiently to multiple production units across the site.
Advancing Industrial Decarbonization
The heat pump, currently under construction, is set to become one of the most powerful industrial heat pumps globally for emission-free steam generation. Powered by renewable electricity, the facility will generate up to 5,00,000 tons of CO₂-free steam annually and deliver a thermal output of approximately 50 MW. This steam will primarily support formic acid production, significantly enhancing the sustainability of the process.
Significant Emissions Reduction Potential
The project is expected to reduce up to 98% of greenhouse gas emissions associated with steam generation in this application. This translates to a reduction of nearly 1,00,000 metric tons of CO₂ per year, making it a major step toward BASF’s decarbonization goals. The system will utilize waste heat from cooling processes at one of the site’s steam crackers, thereby improving overall energy efficiency.
Strong Engineering Collaboration
The evaporator was designed by GIG Karasek, which is also leading the construction of the heat pump system. In close collaboration with BASF, the partners have customized most plant components to suit the complex technical requirements of the Ludwigshafen site. Meanwhile, significant progress has already been made – the plant hall and switchgear building are complete and most piping connections to the steam cracker are in place.
Project Timeline and Government Support
Following the successful delivery of this key component, the project has cleared a major logistical milestone. The plant is scheduled for commissioning by mid-2027. The project highlights BASF’s commitment to innovative, low-carbon technologies in chemical manufacturing. As per the press release, by integrating renewable energy, waste heat recovery, and advanced engineering, the company is setting a benchmark for sustainable industrial steam generation. As industries worldwide accelerate decarbonization efforts, such large-scale heat pump solutions are expected to play a pivotal role in reducing emissions and improving energy efficiency.
