| titleOfInvention | Slurry phase polymerisation process |
| abstract | 20 to 80% by weight of the first polymer is prepared in suspension in the first reactor, 80 to 20% by weight of the second polymer in the second reactor is prepared as a suspension in the presence of the first polymer, and the stream or slurry containing the polymer obtained is the second Is discharged from the reactor and is transported to a flash tank operated at a pressure and temperature such that at least 50 mole% of the liquid component of the slurry entering the flash tank, or the non-polymer component of the stream, is discharged as vapor from the flash tank, The concentration of the C lights (mol%) in the stream or slurry that enters the tank with a molecular weight of less than 50 g / mole is: C lights <7 + 0.07 (40 - T c ) + 4.4 (P c - 0.8) - 7 C H2 / C Et) [wherein, T c and P c are respectively the temperature (℃) and pressure (MPa g) at the location where the vapor is condensed to be discharged from the flash tank, C H2 and C Et are hydrogen and Process for producing a multimodal polyethylene in the respective flash ethylene molar Im] more than one reactor, connected in series to meet in the tank. |
