Title:
HYDROGEN TRANSPORTATION PIPELINES AND SMALL MOVABLE IRON AND STEEL PLANTS
Document Type and Number:
WIPO Patent Application WO/2023/178842
Kind Code:
A1
Abstract:
In response to the problem of hydrogen embrittlement in the synthetic ammonia industry, high-temperature and high-pressure reaction furnaces thereof employ a method of lining wrought iron in steel furnaces. The present invention improves on the aforementioned basis by using pipelines lined with wrought iron to transport hydrogen, and using small movable iron and steel plants to maintain and replace pipelines that reach the end of the service lives thereof.
