Embodiment Construction

[0040] figure 1 is a schematic diagram of a polymerization device in an embodiment of the present invention, and is generally marked as 100 . Polymerization device 100 is shown in highly schematic form. More specifically, identification of various valves and open-loop and closed-loop control devices has been omitted.

[0041] The polymerization unit 100 shown in the examples is fed by two hydrocarbon-rich feed streams 1 and 2, which may be, for example, ethylene and / or propylene.

[0042] The polymerization apparatus 100 includes a purification unit 20 and a regeneration unit 30, and only the polymerization unit 30 is also shown in schematic form. Polymer product 3 was obtained therein. In normal operation of the respective polymerization plant 100 , the hydrocarbon-rich feed stream 1 , 2 passes through the purification vessels 21 - 25 of the purification unit 20 and is polymerized in the polymerization unit 30 .

[0043] In normal operation of the respective polymerizatio...

Abstract

The invention relates to a polymerisation system (100) for obtaining at least one polymerisation product (1) from at least one gaseous, hydrocarbon-rich feed stream (1, 2), which system comprises at least one catalytic and / or adsorptive cleaning device (20) for the at least partial extraction of at least one undesirable component in the at least one feed stream (1, 2) and a regeneration device (10) for the regeneration of the cleaning device (20). The regeneration device (10) is designed to at least intermittently condition and conduct a regeneration gas stream (4) through the cleaning device (20) by means of a partially closed gas circuit (11). The invention further relates to a corresponding regeneration method.

Description

[0001] The present invention relates to a polymerization plant for obtaining at least one polymerization product using at least one gaseous, hydrocarbon-rich feed stream, and to a regeneration unit and a regeneration method according to the preambles of the independent claims. Background technique [0002] In the case of polymerisation products obtained from gaseous, hydrocarbon-rich feed streams, they are generally not used directly in the polymerisation reaction but are purified beforehand. The following describes the preparation of ethylene-propylene elastomers as an example, but is applicable to numerous other installations. [0003] Ethylene-propylene elastomers are described, for example, in the article: "Rubber, 3. Synthesis", Ullmann's Encyclopedia of Industrial Chemistry, online publication, June 15, 2000, DOI 10.1002 / 14356007.a23_239.pub4. This is a class of random copolymers with a fully saturated polymer backbone, for which reason the abbreviation M is used accor...
