Abstract
The utility model discloses a device for extracting hydrogen gas by using synthesis gas, which comprises a film separation system, a raw material gas buffer tank, a variable pressure absorption device and a product gas buffer tank connected in turn. The device can extract pure hydrogen by using hydrogen-enriched synthesis gas for propionaldehyde hydrogenation reaction, and production cost is greatly reduced in comparison with expensive pure hydrogen; while the impermeable gas and the analytic gas generated in the hydrogen extracting process are mixed with part of hydrogen-enriched synthesis gas, and the mixture is used as raw material for synthesizing propionaldehyde by ethylene hydrogen formylation, so that production cost of normal propyl alcohol is greatly reduced.
Description
Technical field
The utility model relates to a kind of device that utilizes synthetic gas to extract hydrogen.
Background technology
Need use hydrogen utilizing propionic aldehyde to prepare in the process of n-propyl alcohol.And the costing an arm and a leg of pure hydrogen, preparation cost is than higher.Some hydrogen-rich synthetic gas price comparisons are reasonable, utilize hydrogen-rich synthetic gas to extract pure hydrogen, and remaining poor hydrogen then mixes with rich hydrogen, synthesize the propionic aldehyde raw material as ethene hydroformylation after the allotment proper ratio.The associated plant that hydrogen-rich synthetic gas is not fully utilized in the prior art.
The utility model content
The utility model purpose: the purpose of the utility model is the deficiency to prior art, and a kind of device that utilizes synthetic gas to extract hydrogen is provided, and is a kind of associated plant that is applicable to synthetic aldehyde of all hydroformylation of olefin and aldehyde hydrogenation synthol.。
Technical scheme: the described device that utilizes synthetic gas to extract hydrogen of the utility model comprises the film separating system, virgin gas surge tank, pressure-swing absorption apparatus and the product gas surge tank that connect successively.Hydrogen-rich raw material of synthetic gas is behind membrane sepn; Be separated into infiltration gas and non-infiltration gas; Infiltration gas wherein obtains high-purity hydrogen as the preparing normal propyl alcohol by propionaldehyde hydrogenation raw material after the virgin gas surge tank advances the pressure-swing absorption apparatus purification, high-purity hydrogen passes through product gas surge tank for use.
For the gassing of separating that produces in the pressure-swing absorption apparatus is further handled, comprise also in the said device that separating the gassing surge tank conciliates the gassing compressor, the said gassing surge tank reconciliation gassing compressor of separating is successively set on after the said pressure-swing absorption apparatus.
Said parsing air compressor is two, and parallel connection is provided with, and one opens one is equipped with.
The utility model compared with prior art, its beneficial effect is: the utility model device can adopt hydrogen-rich synthetic gas to extract pure hydrogen, is used for hydrogenation of propionaldehyde reaction, more expensive pure hydrogen greatly reduces production cost; And the non-infiltration gas reconciliation gassing that in putting forward the hydrogen process, produces mixes with the part hydrogen-rich synthetic gas, as the synthetic propionic aldehyde raw material of ethene hydroformylation, greatly reduces the production cost of n-propyl alcohol.

Fig. 1 is the structural representation of the utility model device.
Embodiment
Be elaborated in the face of the utility model technical scheme down, but the protection domain of the utility model is not limited to said embodiment.
Embodiment 1:The said device that utilizes synthetic gas to extract hydrogen of the utility model comprises film separating system 1 one covers, 2 one of virgin gas surge tanks, pressure-swing absorption apparatus 3 one covers, 4 one of product gas surge tanks, separates 6 two on 5 one reconciliation of gassing surge tank gassing compressor.Film separating system 1, virgin gas surge tank 2 and pressure-swing absorption apparatus 3 are linked in sequence successively, and product gas surge tank 4 is arranged on after the pressure-swing absorption apparatus 3, and the said gassing surge tank 5 reconciliation gassing compressors 6 of separating also are successively set on after the said pressure-swing absorption apparatus 3; Resolve air compressor 6 parallel connections for two and be provided with, one opens one is equipped with.
The working process of the utility model device is: hydrogen-rich raw material of synthetic gas is separated into infiltration gas and non-infiltration gas behind membrane sepn.Infiltration gas wherein obtains high-purity hydrogen as the preparing normal propyl alcohol by propionaldehyde hydrogenation raw material after surge tank advances transformation absorption purification; Non-infiltration gas then mixes with post-decompression rich hydrogen virgin gas with the gassing of separating of transformation absorption, as the raw material of the synthetic propionic aldehyde of ethene hydroformylation.
As stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
Claims (3)
1. a device that utilizes synthetic gas to extract hydrogen is characterized in that: comprise the film separating system, virgin gas surge tank, pressure-swing absorption apparatus and the product gas surge tank that connect successively.
