Method using the free heat from a hydrogen production facility to supply district heating networks with green heat

摘要

the present invention relates to a method for the use of waste heat from a process for the production of hydrogen by steam reforming in order to contribute to the heating of the water in a district heating system.in the conventional way, the synthesis gas, after conversion to steam and heat transfer to the fluid is at a temperature at least equal to 160u00b0c tg; the smoke produced, after heat exchange, and a temperature at least equal to 170 c, the process products itu also fatal vapor temperature tv export more than 200 cfor a network of external vapour from deionized water by heat exchange with the synthesis gas and fumes.;the process according to the invention makes use of the heat available in the above fluid to heat the water in a water heating system is located near a heat transfer fluid through the variable temperature in general of the water circulating in a closed loop. the water in the loop is heated by indirect heat exchange with the synthesis gas and fumes.additional heat is provided according to the requirements from the steam export.;the invention relates to an installation for implementing the process.
