Embodiment 1
[0027] Such as figure 1 As shown, taking a 100,000-ton / year PO plant as an example, the raw material cumene hydroperoxide and fresh propylene react in reactor Ⅰ to produce α,α-dimethylbenzyl alcohol, cumene, and propylene oxide , a liquid phase stream 3 of propylene and propane. Stream 3 is sent to high-pressure propylene recovery tower II for separation, and stream 4 is obtained from the top of the tower, and stream 5 containing α,α-dimethylbenzyl alcohol, cumene, propylene oxide, a small amount of propylene and propane is obtained from the bottom of the tower. Stream 5 is sent to the low-pressure propylene recovery tower III for separation, stream 6 is obtained at the top of the tower, and stream 8 of crude propylene oxide product from which propylene has been removed is obtained at the bottom of the tower. The propylene stream 6 recovered at the top of the low-pressure propylene recovery tower III is divided into two parts, and part of the stream 7 enters the depropanizer IV...
Embodiment 2
[0036] With [embodiment 1], only operating condition changes.
[0037] In liquid stream 3, by weight percentage,
[0038] The content of α,α-dimethylbenzyl alcohol was 26%, the content of cumene was 21.5%, the content of propylene oxide was 10.5%, the content of propylene was 39%, and the content of propane was 2%.
[0039] The operating conditions of the high-pressure propylene recovery tower are as follows: the operating pressure is 1.6MPa, the operating temperature at the top of the tower is 40°C, the operating temperature at the bottom of the tower is 87°C, and the number of theoretical plates is 25.
[0040] The operating conditions of the low-pressure propylene recovery tower are as follows: the operating pressure is 0.2MPa, the operating temperature at the top of the tower is -20°C, the operating temperature at the bottom of the tower is 120°C, and the number of theoretical plates is 20.
[0041] The operating conditions of the depropanizer are as follows: the operatin...
