| titleOfInvention | Method for starting the separation process for purifying acrylic acid crystals from suspension S of crystals of acrylic acid in mother liquor |
| abstract | The invention comprises a crystalline melt space and also a process space and a distributor space separated into a floor having a crystalline melt space and also a process space and a passageway connecting the two spaces, wherein the crystal layer first comprises a crystalline melt circuit. After filling and at least partially filling the process space with an acrylic acid-containing starting liquid that is below the temperature of the suspension S with an acrylic acid crystal formation temperature increased to 15 ° C., the difference in pressure in the crystal melt space and pressure in the distributor space is abruptly abrupt. Continue filling the wash column with suspension S, and optionally with the control solution, until the arithmetic mean of the total waste stream flowing through the filter in the filter tube of the wash column up to this point based on the area of all filters is reduced. Hydraulic tubing with crystal melt circuits up to 80 m 3 / (m 2 · h) In this way, the column S from the suspension of crystals in mother liquor for starting the separation process for the purification of the acrylic acid crystals removed are provided. |
