| 41 | INSTALLATION DE DISTRIBUTION COMPRENANT DES COLONNES A GARNISSAGES STRUCTURES ONDULES-CROISES ET PROCEDE D'AUGMENTATION DE CAPACITE D'UNE INSTALLATION DE DISTILLATION | EP04742618.4 | 2004-04-30 | EP1642072A1 | 2006-04-05 | DUBETTIER, Richard; JUDAS, Frédéric |
| The invention relates to a distillation installation comprising a system of columns (1, 3) and means for conveying a flow (7, 9) that is to be separated into one column (1) in said system. According to the invention, at least one segment (A, D) of one column contains structured packings comprising packs having a non-modified interface if, in the operating segment, the rate ratio is below a rate ratio threshold, said rate ratio being the ratio between the real reflux rate and the minimum reflux rate of the segment, and/or the charge ratio is above a charge ratio threshold, said charge ratio being the ratio between a falling flow of liquid and the section of the segment. Moreover, at least one segment (C, G) of a column, which is designed to operate with a rate ratio above the rate ratio threshold and/or with a charge ratio below the charge ratio threshold, contains structured packings comprising packs having at least one modified interface. | ||||||

| 43 | METHOD AND DEVICE FOR CRYOGENICALLY SEPARATING A MIXTURE OF HYDROGEN AND CARBON MONOXIDE | PCT/FR2009050484 | 2009-03-20 | WO2009144423A4 | 2010-11-18 | COURT PHILIPPE; HERNANDEZ ANTOINE |
| In a method for cryogenically separating a mixture (1) of hydrogen and carbon monoxide optionally including small amounts of methane, argon, and nitrogen for the production of pure CO by partial condensation in one step, the mixture is cooled in an exchange line (3), partially condensed, and at least a portion of the liquid (11) resulting from the partial condensation is sent to the head of a depletion column (15), at least first and second flows (17, 19, 21) rich in carbon monoxide are derived from the depletion column, the first and second flows are cooled at different temperatures, the first flow is sent to a separating pot (27) after expansion, the gas (31) in the separating pot is reheated in the exchange line and sent to the first stage of a carbon monoxide compressor (33, 35, 37) including at least two stages, the second flow is reheated in the exchange line and is sent to a stage of the compressor downstream from the first stage, and the gas in the separating pot and the second flow are reheated in the exchange line at different pressures. | ||||||
