Reuse of natural gas and biogas pipelines for the transport of water for the purpose of supplying properties with heat and / or domestic water

Abstract

Repurposing or converting natural gas or biogas pipelines that were previously used for the transport of gases, characterized by the fact that they are now used for the transport of liquids.

Description

[0001] Natural gas or biogas pipelines that can no longer be used to transport gases for heating purposes should be used to transport water, thus operating similarly to a "cold district heating network," but with a single-flow flow. At the same time, the water can also be used as domestic water on the property.

[0002] The heat transported by the water is partially transferred to a water or brine circuit via heat exchangers. The released heat then serves as a season-independent heat source for the operation of efficient water-to-water or brine-to-water heat pumps for heating the properties. The water transported in this way can be partially can also be used on the property for domestic water purposes. The invention significantly reduces civil engineering costs and achieves significant ecological and economic benefits. The transported water can come from various sources, e.g., from a combination of separate extraction and injection wells, from springs draining into a receiving watercourse, or from receiving watercourses themselves.

Claims

[1] Repurposing or converting natural gas or biogas pipelines that were previously used for the transport of gases characterized by that they are now used for the transport of liquids. [2] Conduit system according to claim 1 characterized by that an amount of heat is transported with these liquids. [3] Conduit system according to claim 1 characterized by that the transported heat is used to supply heat to properties.
