The hydrogen required for this, as well as the necessary water treatment and the methanol synthesis plant itself, are supplied by Hähn. The required carbon is supplied in the form of CO2 by tanker truck.

⁣⁣      The methanol produced is to be sold to supply ships and emergency power systems.

The processes and design drawings were provided to the international chemical company by hähn water treatment. The implementation was carried out by the customer's own workshop.

⁣   Compared to the previous process, considerable amounts of chemicals and energy could be saved. It was also possible to discharge the wastewater directly into a neighboring watercourse.

The electrolysis plant would ensure the independent supply of oxygen and hydrogen to local businesses and facilities. The plant thus ensures regional competitiveness, expands the region's value creation potential and strengthens the business location of northern Rhineland-Palatinate.

Three locations have been shortlisted.

Wood from landscape conservation is used as fuel. The scope of the project included the installation and expansion of an industrial heating network, the construction of wood drying chambers and the installation of a chip drying plant. The project also included modifications to an existing heating plant and the construction of a new production line. Due to the large scope of the project, the work was carried out over a period of 6 years. 

The services provided by hähn included process and plant engineering through to construction supervision and commissioning of the systems.

The process circulation water, which contains fine material that hardens quickly, is produced at a rate of 150 m3/h. Due to the influence of the product, particular attention had to be paid to the necessary qualities and the lowest possible operating and procurement costs. A physical-chemical process was implemented. It was possible to achieve high quality and stable operation.

  The customer's hopes were clearly exceeded. This system also serves as a reference system for the component suppliers. The same system is to be transferred to other locations.

  Update December 2022

A plate heat exchanger was installed in the wastewater flow. In this way, the heat that would otherwise have been generated at great expense using natural gas can be put to good use. The solution from hähn water treatment saves several thousand tons of CO2. With a one-off investment, the customer gains annual savings in the mid double-digit million range.

The basic planning for the planned new plant in Bad Hönningen was also carried out. The process engineering and plant engineering trades were part of the scope of services. Approx. 200 employees were to work at the site during subsequent operation.

As a direct discharger, particular attention had to be paid to the necessary qualities and the lowest possible operating and procurement costs. A physical-chemical process with a subsequent activated carbon stage was implemented.
