Description
Technical field
The utility model is the hydrogen gas recovering device in a kind of PTA production technique, is applicable to the PTA production equipment from having device for producing hydrogen.
Background technology
In PTA production technique, in order to ensure effectively to remove 4-CBA and other foreign pigments in hydrogenator, added hydrogen is seriously excessive, the hydrogen of nearly 85% does not have enough time to participate in reaction and just enters downstream crystallizer with slurry, then when crystallization flash distillation with flash steam and other non-condensable gas high altitude discharge, cause the very large wasting of resources.
Utility model content
The purpose of this utility model directly drains in air to solve hydrogen unnecessary in PTA production technique, cause the technological deficiency of the wasting of resources and the hydrogen gas recovering device in a kind of PTA production technique is provided, by this hydrogen gas recovering device, the adsorption tower of device for producing hydrogen is introduced, by being recycled in hydrogenator after Adsorption CO, CO2 and other organic impuritys after condensation of gas in downstream crystallizer is removed solidifying water.
In order to achieve the above object, hydrogen gas recovering device in a kind of PTA production technique designed by the utility model, comprise crystallizer, condenser, knockout drum, reformed gas surge tank, pressure-swing absorber, hydrogen gas buffer, hydrogen compressor, described crystallizer connects described condenser, knockout drum, reformed gas surge tank, pressure-swing absorber, hydrogen compressor successively by recovery line, and described reformed gas surge tank is also connected with the device for producing hydrogen in PTA production technique.
By this retrieving arrangement, introduce the pressure-swing absorber of device for producing hydrogen after the condensation of gas in downstream crystallizer is removed solidifying water, be recycled remove CO, CO2 and other organic impuritys in adsorption tower after.Can more than 90% be reached to the rate of recovery of hydrogen, incite somebody to action economy system hydrogen consumption greatly.In addition, after above-mentioned retrieving arrangement comes into operation, hydrogen containing tail gas, without the need to again with nitrogen dilution then high altitude discharge, can reduce the loss of device nitrogen.
As preferably, the recovery line place between described condenser and knockout drum is also provided with a vapor pipe and pressure controlled valve.The setting of this gas exhaust duct is in case when transformer kiosk below breaks down, the pressure controlled valve can opened herein carries out high altitude discharge, avoids and causes the accident because pressure in pipeline is excessive.
Further, described hydrogen compressor is connected with the hydrogenator in PTA production technique.Hydrogen after recovery is connected in hydrogenator and realizes recycle.
The advantage of the hydrogen gas recovering device in this PTA production technique has: 1, technique is simple, can with own device for producing hydrogen shared device in factory; 2, organic efficiency is high, and recover hydrogen quality can meet the normal Production requirement of device; 3, practical, way of recycling may extend to the chemical plant installations of other discharge hydrogen containing tail gas; 4, energy-saving and emission-reduction, create environment benefits and economic gains, realize enterprise and social doulbe-sides' victory.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Shown in figure: 1 crystallizer, 2 condensers, 3 knockout drums, 4 reformed gas surge tanks, 5 pressure-swing absorbers, 6 hydrogen compressors, 7 device for producing hydrogen, 8 vapor pipes, 9 pressure controlled valves, 10 hydrogenators.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1, the utility model is the hydrogen gas recovering device in a kind of PTA production technique, comprise crystallizer 1, condenser 2, knockout drum 3, reformed gas surge tank 4, pressure-swing absorber 5, hydrogen compressor 6, described crystallizer connects described condenser, knockout drum, reformed gas surge tank, pressure-swing absorber, hydrogen gas buffer, hydrogen compressor successively by recovery line, and described reformed gas surge tank is also connected with the device for producing hydrogen 7 in PTA production technique.Recovery line place between described condenser and knockout drum is also provided with a vapor pipe 8 and pressure controlled valve 9; Described hydrogen compressor is connected with the hydrogenator 10 in PTA production technique.
By this retrieving arrangement, introduce the pressure-swing absorber of device for producing hydrogen after the condensation of gas in downstream crystallizer is removed solidifying water, be recycled remove CO, CO2 and other organic impuritys in adsorption tower after.Can more than 90% be reached to the rate of recovery of hydrogen, incite somebody to action economy system hydrogen consumption greatly.In addition, after above-mentioned retrieving arrangement comes into operation, hydrogen containing tail gas, without the need to again with nitrogen dilution then high altitude discharge, can reduce the loss of device nitrogen.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
