The invention related to a method for purifying a first fatty acid, preferably polyunsaturated, using an initial mixture further comprising at least one second fatty acid, optionally a third fatty acid and optionally a fourth fatty acid, with the method comprising:

Method for chromatographic purification of a fatty acid

The invention relates to a method for purifying a first fatty acid, in particular a first polyunsaturated fatty acid, using an initial mixture further comprising at least one second fatty acid and a third fatty acid, with the method comprising at least:

Purification of fatty acids by a chromatographic method

A process is provided for recovering a first polyunsaturated fatty acid (PUFA) from a feed mixture including at least one additional fatty acid (e.g., a second fatty acid (FA)). The process optionally comprises: The process also includes:

Chromatographic process for the production of highly purified polyunsaturated fatty acids

A method for purification of a first polyunsaturated fatty acid from an initial mixture is provided. The initial mixture comprises at least one second fatty acid in addition to the first polyunsaturated fatty acid. The method may comprise separating the first polyunsaturated fatty acid and the second fatty acid in a liquid phase in at least one step of a chromatographic separation process, so as to recover, on the one hand, a stream enriched in the first polyunsaturated fatty acid, and on the other hand, a stream enriched in the second fatty acid. The method may further comprise a step of processing the stream enriched in the first polyunsaturated fatty acid to decrease the peroxide value and/or anisidine value of this stream. The disclosure also provides systems or devices suitably adapted for the implementation of such methods.

Chromatographic method for the production of polyunsaturated fatty acids

A process is provided for recovering a first polyunsaturated fatty acid (PUFA) from a feed mixture including at least one additional fatty acid (e.g., a second fatty acid (FA)). The process optionally comprises:

A device allows for continuous regulation of the composition of a fluid mixture that includes at least two components of different polarities. The device is designed, for example, to be inserted in a separation system that the device supplies with a carrier fluid of stabilized composition. The device includes a storage tank (,) receiving a mixture coming from the separation system and at least one auxiliary vessel (,) containing one of the components of the mixture. To control the transfer of this component from auxiliary vessel (,) to storage tank (,), the device further includes at least one tubular capacitive sonde (CS) totally immersed in the fluid mixture, a sonde (TS) for measuring the temperature of the mixture, and a sonde (LS) for measuring the mixture level in storage tank (,). A regulating unit (,) is connected to the various sondes to determine the volume of the component to be transferred to storage tank (,) from the at least one auxiliary vessel in order to restore a set composition for the mixture. The device can be used, for example, for the control of simulated moving beds, of distillation columns, etc.
