Power to Gas: Innovative Hydrogen Project

hartmann referenz eon power to-gas falkenhagen pictureAs one of the first companies worldwide E.ON Gas Storage GmbH demonstrates a way how renewable energy can be stored in the natural gas grid in order to make production independent from consumption. For the demonstration plant in Falkenhagen (Germany) Hartmann Valves supplied 24 ball valves assuring a maximum of operational safety and plant availability. "Pure hydrogen is a challenging fluid. We have decided to use true metal sealing valves because in technical respect this is the best and safest alternative" says Dr. Helge Föcker, Project Manager Storage Facilities & Project Management, E.ON Gas Storage GmbH.

Positive Feedback at Expert's Meetings

In this autumn the Hartmann Team used several opportunities to introduce its quality products in details to trade experts. While at the geothermal energy congresses main focus was turned to expertise around wellheads and service, at the DIAM (German Industrial Valves Fair) high performance valves and innovative pigging concepts took centre stage. At the booth the Team could welcome many customers and interested new contacts. Also the platform for this industrial sector was used for communication with other manufacturers and representatives of  the specialized press.

HARTMANN VALVES defies the crisis in the oil and gas industry with large orders received for deep geothermal projects. For the actual big order placed by Stadtwerke München the first wellhead components for the production well were supplied just in time for drilling start-up to Freiham. At a depth of more than 2.300 meters a huge hot water resource has been located which already as from 2016 is scheduled to be deployed for stoking the district Freiham with natural heat. “We appreciate the positive operational experiences being made with our high-class components. Such excellent results get around in this industry and help us to fill our order books”, states Helmut Berger, registered manager sales, who is in charge of all German geothermal projects.

Integrated Pigging Valve substitutes Pig Launching System

molchhahn hartmann valves webHartmann pigging valves provide a space- and cost-saving substitution for expensive pig launching systems. In addition to its classic use as shut-off valve, the pigging ball valve functions as pig launcher or receiver valve. The simple, secure, and fast insertion or removal of pigs take place through an interlock that is integrated on the side of the pigging valve and that is locked and secured through a bayonet system.

New Reference: Special Ball Valves for Yara

150306 referenz geothermie

For an innovative conversion of the ammonia factory Yara was looking for special shut-off valves for extreme conditions. “Hartmann has the reputation being known as the “Mercedes“ among the valve suppliers. For this important conversion we have made the decision for a high quality solution!” says Werner Döring, Head of Projects and Availability, Yara Brunsbüttel GmbH. The 5“ shut-off ball valves from Hartmann Valves are especially designed for the challenging combination of pure oxygen, steam and high temperatures. Jürgen Rommel, ICA Engineering, is very satisfied with Hartmann’s products and service: “We could not accept any risk during this project. With the wrong supplier we would have endangered the conversion, both technically and time-wise”, The conversion to energy efficient production even secured the economic future of the facility.
