Also process at the sea that has part technology to relate to rock gas in prior art, but all only relate to the treatment technology of section processes work or individual module.Such as these several patented technologies below: the utility model patent that the patent No. is 200520103611.5 relates to a kind of LNG Storage, Transport device of water route conveying liquified natural gas, and this device characteristic is the technological process of having simplified receiving terminal.
The patent No. is that 201110020941.8 patent of invention relates to floating LNG revaporization equipment, is characterized in also comprising the Electric Power Generating Equipment that can produce electric power.Therefore, on the equipment for gasification again in order to make lng regas, additional conduct can be produced the gas turbine generator of the Electric Power Generating Equipment of electric power, thereby substantially can while supply gas and electric power.And, utilize the gas-powered gas turbine generator producing in equipment for gasification again, thereby delete the compressor for the gas compression of gas turbine generator, and then reduce the expense that gas turbine generator is set.And, utilization gas turbine generator produce exhausting air and after generating steam, used as for lng regas machine and generating and the driving power of additional steam turbin generator, thereby by reclaiming used heat, the required energy of integral device is minimized, thereby when being conducive to reduce expense, by using used heat, can also obtain preventing the effect of marine pollution etc.
The patent No. is the ship that 201180019016.1 patent relates to a kind of conveying liquified natural gas reservoir vessel, is characterized in having utilized fully hull space, to more load natural gas storage container.
Prior art does not provide the technological scheme re-vaporizing after a kind of can liquefaction to rock gas at sea.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of memory device that can rock gas be liquefied, be re-vaporized at sea.
In order to solve the problems of the technologies described above, one disclosed by the invention is for natural gas liquefaction, the floating storage device of re-vaporization, comprise oceangoing ship body, feed system, decarbonization desulfurization system, dehydration system, liquefaction system, the first flash steam compressor assembly, the second flash steam compressor assembly, waste-gas burning system, refrigeration agent replenishment system, heat medium system, re-vaporization system, holding vessel, loading dock, described holding vessel is arranged on oceangoing ship body inside, described feed system and loading dock are separately positioned on intermediate portion, oceangoing ship body both sides, described dehydration system is arranged on described feed system right side, described liquefaction system is arranged on described dehydration system right side, described waste-gas burning system is arranged on described liquefaction system right side, described refrigeration agent replenishment system is arranged on described feed system left side, and described heat medium system is arranged on the left side of described refrigeration agent replenishment system, described the first flash steam compressor assembly is arranged on the left side of described loading dock, and described decarbonization desulfurization system is arranged on the left side of described the first flash steam compressor assembly, described re-vaporization system is arranged on the right side of described the second flash steam compressor assembly, described feed system connects decarbonization desulfurization system by pipeline, described decarbonization desulfurization system connects dehydration system by pipeline, described dehydration system connects liquefaction system by pipeline, described the first flash steam compressor assembly is connected respectively holding vessel and liquefaction system with the second flash steam compressor assembly by pipeline, described refrigeration agent replenishment system connects liquefaction system by pipeline, described heat medium system connects decarbonization desulfurization system by pipeline, described re-vaporization system is connected with holding vessel by pipeline, and described waste-gas burning system is connected with each system gas sampling equipment.
In prior art, each functional processing module technology is very ripe, and its process flow steps and land natural gas liquefaction, re-vaporization memory device do not have too big difference.Main technique route is after rock gas separates virgin gas by feed system, to enter into decarbonization desulfurization system to carry out sulphur removal de-carbon, entering into dehydration system dewaters again, and then enter into liquefaction system and liquefy, the rock gas after liquefaction enters holding vessel and stores.Flash steam compressor assembly compresses the rock gas evaporating in holding vessel, after cooling, then is transported to liquefaction system and liquefies, then enter holding vessel and store; Heat medium system is mainly to utilize combustion gas turbine machine
The used heat kerosene of heating producing, then by hot oil boiler, add warm water and become steam, then the ammonia solution that goes to heat in decarbonization desulfurization system, make it by the carbon dioxide separation in rich amine aqueous solution and get rid of.Refrigeration agent replenishment system, major function is to supplement after the loss of liquefaction system refrigeration agent; Loading dock is mainly that rock gas in holding vessel is lightered to other boats and ships; Re-vaporization system is to be used as peak regulation when natural gas supply is not enough nearby, after the natural gas vaporization after liquefying, re-uses; Waste-gas burning system mainly burns the inflammable gas producing in each system, leak.
Feed system and loading dock are symmetricly set on to oceangoing ship body two middle side parts and are not only convenient to rock gas input and output, simultaneously for whole system layout provides strong condition, make relevant supplementary equipment around the beginning of technological process and end, form ring structure.This layout can make the holding vessel that fire good are housed concentrate as far as possible, has dwindled deathtrap; In limited space, shortened the distance of assistant service system to serviced system, avoided the too small problem that affects output of pipeline bending radius simultaneously; Whole installation weight can be arranged symmetrically with, guarantee the afloat stability of whole device.
