Definitions
- the present invention relates to a process for extracting residual monoglycerides in a cross section of fatty acid alkyl esters derived from transesterification, used in particular to manufacture biodiesel.
- alkyl esters of fatty acids (abbreviated EAAG) is understood to mean, preferably, the esters resulting from the transesterification of C1 to C8 alcohols with C8 to C36 fatty acids.
- EAAGs therefore correspond to the formula: R 1 CO-OR 2 , where R 1 CO is an aliphatic acyl group containing from 8 to 36 carbon atoms and R 2 is a linear or branched alkyl group containing from 1 to 8 carbon atoms .
- the fatty acid methyl esters are obtained by transesterification of fatty acids of vegetable or animal origin with methanol, generally in the presence of a basic catalyst, such as NaOH.
- the fatty acids come mainly from vegetable oil, such as rapeseed, sunflower, soy, peanut, olive, sesame, safflower, coconut, palm, castor oil, jatropha, microalgae, etc.
- Fatty acids can also come from animal sources, such as residues from the agri-food industry such as slaughterhouse residues, animal fats such as chicken fat, beef, pork, fish, or used cooking oils.
- Methyl esters of fatty acids are the major constituents of biodiesel produced today. Therefore, the present invention is generally described in the following text and examples with reference to the purification of a section of fatty acid methyl esters. Nevertheless, the process of the invention is obviously not limited to the purification of fatty acid methyl ester cuts, but applies to any section of alkyl esters of fatty acids as defined above, such as for example, ethyl esters of fatty acids or esters derived from transesterification of fatty acids with 2-ethylhexanol.
- the EN 14214 standard (or ASTM D6751) describes the requirements for EAAGs (EMAGs) used as biodiesel.
- TLF filterability limit temperature
- EN 1 16 in Europe or ASTM method D 2500 in the USA.
- This TLF criterion corresponds to the blocking temperature of a cold filter in the presence of EAAG. This temperature depends in part on the residual saturated monoglyceride content of the EAAGs resulting from transesterification. In particular, the residual monoglyceride content of the EAAGs must be less than or equal to 0.8% by weight relative to the weight of the EAAGs according to the EN 14214 standard. This residual monoglyceride content is measured according to the EN 14105 standard in biodiesels.
- US2007 / 0151 146 discloses a method of separation and filtration, using adsorbent compounds (such as granular glucose, boric acid, or diatomaceous earth), steryl glycosides biodiesel. This process can sometimes result in a small amount of residual monoglycerides simultaneously with the steryl glycosides.

- the object of the present invention is therefore to provide a simple method for the selective extraction of residual monoglycerides from EAAGs, in order to improve the cold resistance of EAAGs, and to make them usable as biodiesels, (in accordance with the EN 14214 standard).

- the monoglycerides are extracted in the phase containing the light alcohol (phase of the polar solvent).
- the polar solvent (SP) is introduced against the current of the EAAG cut, leading to the production of a heavy phase comprising the purified EAAGs, and a light phase enriched with monoglycerides.
- the method of the invention comprises the following steps:

- Steps 2 to 6 form a first sequence representing the 1st extraction stage.
- Phases B1 and H5 are then weighed and analyzed (see Table 9, end sequence 1).
- the continuation of the test consists of starting the second sequence in the presence of the contents of the ampoules resulting from the preceding sequence and re-injecting fresh methanol and the raw material ester respectively into ampoules 1 and 5. And so on, until you realize 5 complete sequences. In fact, the sequences simulate the setting in regime of the column with 5 stages.
