The invention is directed to a process for separating a compound from an aqueous feed stream wherein said compound is dissolved. The process of the invention comprises - adding a crystallisation agent to said feed stream, thereby causing at least part of said first compound to crystallise, resulting in a mixture of crystals and a liquid, - separating at least part of the crystals from the liquid, leaving a supernatant, - subjecting at least part of the supernatant to a membrane separation process, producing a concentrate;
wherein the crystallisation agent comprises a second compound with a higher solubility in water than the first compound.

The present invention discloses a heat exchanger system for thermochemical storage and release. The system comprises a thermal exchange circuit with a heat exchanger fluid, the circuit further in thermal connection with a thermochemical module. The thermochemical module comprises a thermochemical material that stores and releases heat by a thermochemical exchange process under release or binding of a sorbate. The thermochemical module comprises a compartment structure that compartments the thermochemical material and further comprises a channel structure. This provides an exchange of the sorbate and the thermochemical material via the channel structure to the compartment structure. A method for the preparation of the compartment structure is also described. In this method, the thermochemical material is brought in a liquid phase and inserted in the compartment structure, while keeping the channel structure free from the liquid phase; and subsequently dried.
