Abstract
A process for separating components of a reactor off gas is provided. A related reactor system is also provided. The reactor system may include a high pressure tubular reactor and/or an autoclave reactor and may be used for the production polyolefin polymers.
Claims23
A process for separating components of a reactor off gas comprising:
- 1) passing a reactor off gas from a polymerization process through one or more product separators to produce a gas phase (a) and a liquid phase (b);
- 2) cooling the gas phase (a) to produce a cooled gas phase (a) and passing the cooled gas phase (a) to a first gas/liquid separator to produce a first gas phase and a first liquid phase;
- 3) compressing the first gas phase to produce a compressed first gas phase and cooling the compressed first gas phase to produce a cooled first gas phase and passing the cooled first gas phase to a second gas/liquid separator to produce a second gas phase and a second liquid phase;
- 4) compressing the second gas phase to produce a compressed second gas phase and cooling the compressed second gas phase to produce a cooled second gas phase and passing the cooled second gas phase to a third gas/liquid separator to produce a third gas phase and a third liquid phase;
- 5) compressing the third gas phase to produce a compressed third gas phase and cooling the compressed third gas phase to produce a cooled third gas phase and passing the cooled third gas phase to a fourth gas/liquid separator to produce a fourth gas phase and a fourth liquid phase;
- and
- 6) directing the liquid phase (b) to a recovery stage.

A reaction system comprising:
- 1) one or more compressors in fluid connection with
- 2) one or more reactors in fluid connection with
- 3) one or more product separators in fluid connection with
- 4) a plurality of gas/liquid separators fluidly connected in series, wherein at least one of the product separators comprises an off gas, and the off gas is in fluid connection with at least one of the gas/liquid separators and wherein the plurality of gas/liquid separators are represented by Ni, Nx, Ny, and Nf, and wherein:
- Ni is the initial gas/liquid separator;
- Nx is one or more first middle gas/liquid separators, wherein x is a number from 1-97;
- Ny is one or more second middle gas/liquid separators, wherein y=t−(x+2);
- Nf is the final gas/liquid separator;
- t is the total number of separators in the series and is a number from 4-100;
- and
- the one or more reactors is selected from the group consisting of:
- tubular reactors, autoclave reactors, and a combination thereof.
