Abstract
This invention relates to the design of a process by intermittent dielectric heating combined with a recycling system. This process consists in subjecting reagents to electromagnetic waves selected in the frequencies ranging between 300 GHz and 3 MHz intermittently using a recycling system. This process enables the treatment of oils that are hardly absorbent as well as great investment savings. This process enables operation on different scales, whether in laboratories, on a semi-industrial or industrial scale, without forfeiting the advantages of continuous dielectric heating.
Claims27
A process of heat treatment in a chemical synthesis comprising:
- circulating one or more reagents in a recycling system;
- subjecting said reagent(s) to electromagnetic waves intermittently, wherein the reagent(s) is/are subjected to said electromagnetic waves in one part of the recycling system and not in another part of the recycling system;
- wherein said heating is intermittent dielectric heating,
- and wherein the frequencies are microwave frequencies (MW) from about 300 MHz to about 30 GHz;
- or high frequencies (HF) from about 3 MHz to about 300 MHz.
A process of heat treatment in a chemical synthesis, comprising:
- circulating one or more reagents in a recycling system;
- subjecting said reagent(s) to electromagnetic waves intermittently, wherein the reagent (s) is/are subjected to said electromagnetic waves continuously in one part of the recycling system and not in another part of the recycling system;
- wherein said electromagnetic waves are selected in the frequencies ranging between 300 GHz and 3 MHz.
A process of heat treatment in a chemical synthesis comprising:
- circulating one or more reagents in a recycling system;
- and
- subjecting said reagents to electromagnetic waves intermittently, wherein the reagents are subjected to said electromagnetic waves in one part of the recycling system and not in another part of the recycling system;
- wherein said heat treatment is intermittent dielectric heating, wherein at least one of said reagents is a compound which hardly absorbs electromagnetic waves, and wherein the reagents are exposed to electromagnetic waves selected in the frequencies ranging between 300 GHz and 3 MHz.
A process of heat treatment in a chemical synthesis comprising:
- circulating one or more reagents in a recycling system;
- and
- subjecting said reagent (s) to electromagnetic waves, wherein the reagent (s) is/are subjected to said electromagnetic waves continuously in one part of the recycling system and not in another part of the recycling system;
- wherein said heating is intermittent due to circulation in said recycling system.
