Embodiment
[0009] like figure 1 The shown dry hydrogen recovery device includes a gas-liquid separation tank 1, the right side of the gas-liquid separation tank 1 is provided with a hydrogen inlet 2, the top of the gas-liquid separation tank 1 is provided with a hydrogen outlet 3, and the bottom is provided with a drain port 4 .
[0010] After the unreacted hydrogen in the hydrogenation reaction is cooled, it enters the gas-liquid separation tank 1 through the hydrogen inlet 2 for gas-liquid separation. After the separation, the dried hydrogen is discharged through the hydrogen outlet 3 and recovered, and the water is discharged through the water outlet 4, which can Reduce the moisture in the recovered hydrogen to prevent the product from becoming rancid during the hydrogenation reaction of the recovered hydrogen.

The invention discloses a dry hydrogen recovering device, which relates to the oleochemical industry, specifically to dry recovery of unreacted hydrogen in a hydrogenation reaction. The dry hydrogen recovering device comprises a gas-liquid separation tank; the gas-liquid separation tank is provided with a hydrogen inlet at the right side, a hydrogen outlet at the top and a water outlet at the bottom. The dry hydrogen recovering device has a simple structure and is convenient to operate; through additional arrangement of the dry hydrogen recovering device at the front of a hydrogen circulator, moisture in cooled hydrogen is removed and is not cyclically brought to a reaction unit, so influence of moisture on the hydrogenation reaction is reduced and a product is prevented from rancidity.
Description
[0001] technical field [0002] The invention relates to the oil chemical industry, in particular to the dry recovery of unreacted hydrogen in the hydrogenation reaction. Background technique [0003] In the oleochemical industry, the hydrogenation reaction has high requirements on the dryness of hydrogen, but in the hydrogenation reaction under the existing technology, the cooled hydrogen enters the reaction device directly through the hydrogen cycle machine, and the dryness of the hydrogen cannot be guaranteed , often due to excessive moisture in hydrogen, resulting in product rancidity during hydrogenation reaction. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a dry hydrogen recovery device. [0005] Technical solution: A dry hydrogen recovery device, including a gas-liquid separation tank, the right side of the gas-liquid separation tank is provided with a hydrogen i...
