Method and facility for drying by means of hydrothermal carbonization and filtering
The present invention relates to the field of heat treatment of a product to be dehydrated, such as sludge from a waste water treatment process. The present invention relates more particularly to a method and to a facility for drying such a product, making it possible to implement a hydrothermal carbonization operation on reactor 1 followed by a filtering and drying operation, preferably on a heating filter press 6. In order to dry said product in the heating filter press 6, a heat-transfer fluid from a heat exchanger 2 is made to flow in said heating filter press. The heat exchanger 2 is arranged so as to transfer, to the heat-transfer fluid, at least some of the heat contained in the product to be dehydrated that is output from the reactor 1.

Method for the hydrothermal carbonisation of a biomass and associated device
Disclosed is a method for heating a biomass moving along an industrial treatment line including an inlet (1) for the incoming biomass, a heating unit (4), and a treatment station (5). A fraction of the biomass heated by the heating unit (4) is returned along a return branch (R) to a mixing station (2) upstream of the heating unit (4) so as to form, together with the incoming biomass, a mixture having a temperature above the temperature of the incoming biomass, the heated biomass fraction being removed at an outlet (51) of the treatment station (5).

METHOD FOR THE DIGESTION AND HYDROTHERMAL CARBONIZATION OF SEWAGE SLUDGE
The invention relates to a method for hydrothermal carbonization and digestion of sewage sludge, wherein the device for hydrothermal carbonization and the device for digestion are flown through by the sewage sludge in alternating order and/or wherein the sewage sludge is first supplied to a hydrothermal carbonization and subsequently to the digestion.
A method and facility for the hydrothermal carbonization of pasty products or waste, or sewage sludge, in a pressurized reactor heated to carbonization temperature T0. Before entering the reactor, the products undergo: pressurization, and preheating in an exchanger, by a thermal fluid flowing in a closed loop, and receiving heat from products exiting the reactor; the thermal fluid is heated in the loop by an external heat source, downstream from the exchange with the products exiting the reactor, and upstream from the preheating of the products entering the reactor, and the temperature of the product to be treated, preheated by the thermal fluid, when it enters the reactor, is between the carbonization temperature T0 and T0-100° C. The product to be treated flows in at least one tube, where in at least one location therein, liquid is injected to create a liquid ring against the inner wall, and reduce pressure drops.
