Description

Carbon dioxide management system and method
Technical field
The application relates to a kind of carbon dioxide management; More particularly, relate to a kind of for effectively supply with the carbon dioxide management system and method for carbon dioxide to carbon dioxide repository.
Background technology
Carrying out a lot of using the carbon dioxide of the main cause as global warming as water stratum, ocean, when seawater stratum, gas and crude oil production charging pressure gas or be stored in gas and the research in the space of crude oil production after finishing, wherein said carbon dioxide traps and stores in a plurality of generations source.
For liquid carbon dioxide being transplanted on to corresponding area, expection will be used pipe line and carbon dioxide travel line.Wherein, carbon dioxide travel line is considered to counte-rplan.
The transportation of carbon dioxide is in the past to use carbon dioxide carrier, and described carbon dioxide carrier, and is discharged in atmosphere compared with little because of the boil-off gas scale of construction producing for edible with the high pressure vessel (15～30bar) of low capacity.But in the high-capacity large capacity carrier transporting more than 10,000 tons/time, be discharged in atmosphere not only aspect environmental problem, and also unfavorable at economic aspect.Therefore having produced exploitation does not have in the situation of airborne release, the demand of the method for transporting.
On the other hand, in order to transport with large capacity, reduce the design pressure of storage tank favourable at economic aspect.Aspect travel line, while improving storage pressure, exist the thickness due to container will cause very greatly safety of structure and stability problem.
Otherwise it is unfavorable that high-capacity carbon dioxide is transported aspect the composition of boil-off gas generation and carbon dioxide.Therefore, need a kind of and have nothing to do with the composition of noncondensable gas in a way, and under low pressure also can be with the technology of liquid state storage.
According to No. 10-2008-0127318th, prior art korean patent application, proposition has the concept patent that carbon dioxide and other goods can be loaded onto ship simultaneously, but specifically to the management system of the carbon dioxide arranging in boats and ships and the but not record of carbon dioxide management method thereof.
In addition, carrying out arranging that particular adsorbent is carried out gaseous state absorption and the research of the concept of storing to transport in the storage tank of carrier.Because a large amount of trappings are continuous processes, therefore need liquid storage or pipe line to carry.But there is following shortcoming: when the shipment of liquid carbon dioxide, need to unnecessarily again heat, and the in the situation that of pipe line, the time that packs boats and ships into becomes very long, and the non-absorbing carbon dioxide now producing for recirculation, expensive expense.In addition, conventionally, when the bulk density (Bulk Density) of commercial adsorbent is 0.6～0.8g/cm 3between and account for 50,000m 31/3 o'clock, just there is normal shortcoming of carrying about 12,500 tons.
Therefore, the normally liquid conveying of carbon dioxide travel line.For the carbon dioxide of handover is maintained to liquid state, more than need to maintaining triple point (under-56.6 ℃ of conditions for 5.18bar), and overcritical (31.1 ℃, 74.8bar) below.But, because heat is delivered in storage tank or in the inner accumulation of the kinetic energy because of fluid of filling, cause the carbon dioxide of a great deal of to evaporate.It is very important that mode by it with less expensive is processed.
At present, production carbon dioxide is for for beverage, its method is, under gaseous state, the miscellaneous gas containing high concentration carbon dioxide is carried out to pre-processing, after being compressed, in minute flow container (Knock-drum), remove moisture, gaseous carbon dioxide is compressed to rear utilization again and adopt the absorption refrigerating machine of ammoniacal liquor to carry out the liquefaction of 2 stages, thereby produce liquid carbon dioxide.The boil-off gas that when liquid carbon dioxide of producing is stored, (near 18～20bar 25 ℃) produces is delivered to before compressor in operation again, and by again compressing, the circulating process of condensation produces.
But, in large capacity carbon dioxide carrier, store pressure low in the situation that, near the triple point of carbon dioxide, utilize and use the absorption refrigerating machine of ammoniacal liquor that it is liquefied while also again delivering to storage tank, have complex procedures, the shortcoming that operating charges and investment cost are larger.
Especially, at storage pressure, low in the situation that, relatively the ratio of noncondensable gas increases, thereby temperature that need to be lower when pressurization especially exists the worry of the situation below the triple point that is reduced to carbon dioxide, so unfavorable in operating aspect.
In addition, recently after traditional burning, trap (Post-Combustion), at the integrated gasification combined cycle plants (IGCC with corresponding to trapping (Pre-Combustion) before burning, Integrated Gasification Combined Cycle) and in the situation of the method capturing carbon dioxide such as all-oxygen combustion (Oxy Fuel) trapping, carbon dioxide contains a large amount of noncondensable gass.
Carbon dioxide, trapping post-processing and boil-off gas that following table 1 relates to each burning trapping form.
In following table 1, trapping post-processing 1 is to remove the composition again circulating after a part of noncondensable gas, and boil-off gas 2 is conditions of about 0.0015/ day that described boil-off gas produces flask volume under 7bar condition.
Table 1
As shown in table 1, in integrated gasification combined cycle plants (IGCC), nitrogen (N 2) and hydrogen (H 2) content large; The in the situation that of all-oxygen combustion, nitrogen (N 2), oxygen (O 2), argon (Ar) content is many, near the triple point of pure carbon dioxide, under 7bar condition, concentrated captured gas can not be liquefied completely, thereby in trapping source, removes a part of noncondensable gas by land.
This becomes the very large shortcoming of transporting carbon dioxide at sea.In addition, as shown in table 1, in order to carry out sea, to transport, the concentration of carbon dioxide at least will reach more than 99.5 % by mole, could near 7bar pressure, be stored in carbon dioxide storage tank.
On the other hand, in the situation that the carbon dioxide storage pressure in carbon dioxide storage tank is low, relatively the amount of boil-off gas increases, and the ratio of noncondensable gas increases, thereby exist, is difficult to liquefaction device the problem of its liquefaction.
And in the situation that carbon dioxide storage pressure is low, when liquid carbon dioxide is supplied to carbon dioxide repository, due to the suction reduction of utilized drawing pump, existence cannot realize the shortcoming that carbon dioxide is supplied with swimmingly.
