US 2026/0233129 A1 · APPARATUS AND PROCESS FOR RECOVERY OF A VALUABLE MATERIAL

Abstract

Membrane filter press comprising two end elements and a plurality of filter elements, wherein a main space which is delimited from a rear back or filtrate space by a filter medium is in each case formed between two filter elements and associated frame sections, wherein at least one filter element is formed as a membrane filter element by two filter elements forming a main space and comprises a fluidizable interior which is delimited by at least one flexible membrane in the direction of the filter medium and wherein the main space has at least one feed channel for a substance mixture to be separated and the back or filtrate space comprises at least one filtrate channel for the filtrate, in particular at least one filtrate channel which leads to a collecting channel and wherein the main space comprises not only the feed channel but also at least one discharge opening, in particular a discharge opening arranged vertically above the feed channel. The invention further comprises a plant and a process for producing a solid product and/or valuable material.

Dependent claims

Plant (100) for producing at least one product comprising a first process unit (200) and at least one connected separating unit (300), wherein the process unit (200) comprises the following:

at least one reactor (201, 202) for treating a substance mixture,
at least one feed conduit (204) for introducing at least one reactant into the at least one reactor (201, 202),
a connecting conduit (206) for discharging a suspension comprising at least one precipitated, solid product to the separating unit (300), wherein the separating unit (300) is configured for separating the at least one solid product and discharging of at least one harmful byproduct or inhibitor and the separation unit (300) comprises two (302, 304), three or four separation apparatuses with at least two separation apparatuses (302, 304) being serially connected via
a conduit (214, 314) to a receiving and conditioning unit (400) configured for conditioning a liquefaction medium to liquefy valuable material collected as a filter cake in the membrane filter press (340), and via
a return conduit (208) leading to the process unit (200) to recycle the at least one liquefied valuable material.

Process for producing at least one solid product in a plant (100), comprising the following steps:

a. provision of a process unit (200) and a separating unit (300),
b. introduction of at least one reactant into the process unit (200) and production of at least one solid product and byproduct in a substance mixture,
c. separation of the at least one solid product and discharging of at least one harmful byproduct or inhibitor using two (302, 304), three or four separation apparatuses in the separating unit (300), wherein at least two separation apparatuses (302, 304) are serially connected and the following steps are performed:
d. collection of a first sub-amount of the separable solid product as filter cake in the first separation apparatus (302),
e. dehumidification of the first sub-amount of the solid product in the first separation apparatus (302),
f. sending the filtrate (FT) separated in the first separation apparatus (302) and comprising valuable material selected from reactants, byproducts, auxiliaries and/or end products to the last separation apparatus (304) which is configured as a membrane filter press (340),
g. collection of a separable valuable material as filter cake in the last separation apparatus (304), and
h. dehumidification of the valuable material in the last separation apparatus (304),
i. liquefaction of the valuable material collected in the membrane filter press (340) and solidified as a filter cake inside the membrane filter press (340) with a liquefaction medium, and
j. recycling of the liquefaction medium with the valuable material dissolved therein into the process unit (200).
