| titleOfInvention | Process for the production of tertiary ethers from a catalytic cracking charge comprising two stages of extractive distillation. |
| abstract | A process for the production of tertiary ethers (MTBE, ETBE) is described in which a hydrocarbon cut (1) with four carbon atoms is reacted with methanol or ethanol (2, 3) in a reactor (6) and after distillation (CI), the ethers (11) and a distillate (10) are recovered. A first extractive distillation of the distillate is carried out in the presence of a selective solvent (27) for olefinic hydrocarbons in a column (CI I) and a top fraction (15) rich in saturated hydrocarbons and a bottom fraction (18) are recovered. rich in olefins, solvent and alcohol. The olefins (20) are separated from the solvent and the alcohol (24) by a second extractive distillation (CI I I). The olefins are isomerized in a backbone isomerization reactor (5) and the isomerizate is recycled (2) to the reactor (6). The alcohol and the solvent are separated in a stripping column (CI V), the alcohol (26) is recycled to the synthesis reactor (6) while the solvent (27) is recycled to CI I. The bottom temperature of the second column (CI I I) can be lowered by adding fresh (4) or recycled (34) alcohol. Application to additives increasing the octane number of gasoline. |
