Description

Oppfinnelsen angår en anordning til lagring og transport av flytendegjort naturgass (LNG) i en tank hvor det fås et avkok som strømmer fra tanken til en kompressor og deretter til en varmeveksler, som blir tilført et kjølemiddel fra et kjøleanlegg, og som skaffer en kondensering av en bestanddel av avkoket. The invention relates to a device for storing and transporting liquefied natural gas (LNG) in a tank where a decoction is obtained which flows from the tank to a compressor and then to a heat exchanger, which is supplied with a refrigerant from a refrigeration plant, and which provides a condensation of a component of the decoction.

Oppfinnelsen er basert på den anordning som er vist og beskrevet i NO 305525 og den internasjonale søknad nr. NO98/000888 tilhørende den samme søker. Det skal forstås at fremstillingen av dette patentskrift eller internasjonale søknad skal inngå som en del av fremstillingen av oppfinnelsen og at det i den følgende beskrivelse av oppfinnelsen derfor bare behøver å bli beskrevet de bestanddeler av den internasjonale søknads anordning som direkte er tilsluttet oppfinnelsen. The invention is based on the device shown and described in NO 305525 and the international application no. NO98/000888 belonging to the same applicant. It shall be understood that the preparation of this patent document or international application shall be included as part of the preparation of the invention and that in the following description of the invention it is therefore only necessary to describe the components of the device of the international application which are directly connected to the invention.

Andre kjente lignende anlegg er beskrevet i NO 17532 og US 6672104. Other known similar facilities are described in NO 17532 and US 6672104.

NO 175392 beskriver et anlegg med mellomtrykksbeholder, noe som er et prinsipp som har lenge har vært brukt i kjøleanlegg. Mellomtrykksbeholderen kjøler riktignok avkoket men på en helt annen måte og på et annet sted i prosessen enn det som er tilfellet med anordningen i henhold til oppfinnelsen. NO 175392 describes a system with an intermediate pressure vessel, which is a principle that has long been used in refrigeration systems. The intermediate pressure container does indeed cool the decoction, but in a completely different way and at a different place in the process than is the case with the device according to the invention.

US 6672104 beskriver et anlegg for kondensering av en gassblanding hvor hensikten i tillegg til kondenseringen er å endre sammensetningen slik at denne etter kondensering blir likeverdig eller identisk med en annen gassblanding som befinner seg på nedstrømssiden. US 6672104 describes a plant for condensing a gas mixture where, in addition to the condensation, the purpose is to change the composition so that after condensation it becomes equivalent or identical to another gas mixture located on the downstream side.

Hensikten med oppfinnelsen er å forbedre den ovennevnte anordning for oppnåelse av en optimal drift av denne. The purpose of the invention is to improve the above-mentioned device in order to achieve an optimal operation thereof.

Denne hensikt blir ifølge oppfinnelsen oppnådd ved en anordning til lagring og transport av flytendegjort naturgass (LNG) i en tank hvor det fås et avkok som strømmer fra tanken til en kompressor og deretter til en varmeveksler, som blir tilført et kjølemiddel fra et kjøleanlegg, og som skaffer en kondensering av en bestanddel av avkoket, at det mellom tanken og kompressoren er anordnet en ytterligere varmeveksler som likeledes blir tilført kjølemiddel fra kjøleanlegget, og som kjøler, men ikke kondenserer avkoket, som strømmer fra tanken til kompressoren, idet kjølemiddelet blir tilført den ytterligere varmeveksler via en styrbar reguleringsventil, at det mellom den ytterligere varmeveksler og kompressoren er anordnet en temperatursensor, som avføler temperaturen på avkoket, og at reguleringsventilen blir styrt av en styreinnretning som blir tilført signaler fra temperatursensoren for styring av strømmen av kjølemiddel til den ytterligere varmeveksler på en slik måte at temperaturen på avkoket fra denne varmeveksler til kompressoren blir holdt konstant. According to the invention, this purpose is achieved by a device for storing and transporting liquefied natural gas (LNG) in a tank where a decoction is obtained which flows from the tank to a compressor and then to a heat exchanger, which is supplied with a refrigerant from a refrigeration plant, and which provides a condensation of a component of the decoction, that an additional heat exchanger is arranged between the tank and the compressor, which is also supplied with refrigerant from the refrigeration plant, and which cools, but does not condense the decoction, which flows from the tank to the compressor, as the refrigerant is supplied to it additional heat exchanger via a controllable control valve, that a temperature sensor is arranged between the additional heat exchanger and the compressor, which senses the temperature of the decoction, and that the control valve is controlled by a control device that receives signals from the temperature sensor for controlling the flow of coolant to the additional heat exchanger in such a way that the temperature p that the decoction from this heat exchanger to the compressor is kept constant.

Oppfinnelsen vil i det følgende bli beskrevet nærmere under henvisning til tegningen som viser et utførelseseksempel på en anordning ifølge oppfinnelsen. In the following, the invention will be described in more detail with reference to the drawing which shows an exemplary embodiment of a device according to the invention.

Den eneste figur er et koblingsskjema som skjematisk viser et utførelseseksempel på et anlegg til lagring eller transport av LNG med en anordning ifølge oppfinnelsen. The only figure is a connection diagram which schematically shows an embodiment of a facility for storing or transporting LNG with a device according to the invention.

Som det fremgår av figuren omfatter anlegget en tank 2 som inneholder LNG 4 hvis overflate er angitt med henvisningstallet 6. Tankrommet over denne overflate 6 kommuniserer via en rørledning 8 med innløpet av en første kompressor 12 som er drevet av en motor 14. As can be seen from the figure, the plant comprises a tank 2 containing LNG 4 whose surface is indicated by the reference number 6. The tank space above this surface 6 communicates via a pipeline 8 with the inlet of a first compressor 12 which is driven by a motor 14.

Utløpet av kompressoren 12 kommuniserer via en rørledning 16 med innløpet av en første passasje 18 av en første kjøler eller varmeveksler 20.1 varmeveksleren 20 er det anordnet en annen passasje 24, hvis innløp får tilført et avkjølt kjølemiddel fra et på en i og for seg vanlig måte oppbygget kjøleanlegg 26 via en rørledning 30, og hvis utløp returnerer oppvarmet kjølemiddel til kjøleanlegget 26 via en ledning 28. The outlet of the compressor 12 communicates via a pipeline 16 with the inlet of a first passage 18 of a first cooler or heat exchanger 20.1 the heat exchanger 20, another passage 24 is arranged, the inlet of which is supplied with a cooled coolant from a in and of itself usual way built-up cooling system 26 via a pipeline 30, and whose outlet returns heated refrigerant to the cooling system 26 via a line 28.

Kjøleanlegget 26 omfatter en annen kompressor 58 som er drevet av en motor 60. På nedstrømssiden av den annen kompressor 58 er det anordnet en mellomkjøler 62, på hvis nedstrømsside det er anordnet en tredje kompressor 64. The cooling system 26 comprises another compressor 58 which is driven by a motor 60. On the downstream side of the second compressor 58 an intercooler 62 is arranged, on the downstream side of which a third compressor 64 is arranged.

Innløpet av den annen kompressor 58 kommuniserer med utløpet av en første passasje 66 av en annen kjøler eller varmeveksler 68 via en rørledning 70. The inlet of the second compressor 58 communicates with the outlet of a first passage 66 of another cooler or heat exchanger 68 via a pipeline 70.

Utløpet av den tredje kompressor 64 kommuniserer med innløpet av en annen passasje 72 av den annen varmeveksler 68 via en mellomkjøler 48 og en rørledning 73, og utløpet av den annen passasje 72 av den annen varmeveksler 68 kommuniserer med innløpet av en ekspansjonsturbin 74, hvis utløp er forbundet med innløpet av den annen passasje 24 av den første varmeveksler 20 via rørledningen 30. Den tredje kompressor 64 er drevet av ekspansjonsturbinen 74. The outlet of the third compressor 64 communicates with the inlet of another passage 72 of the second heat exchanger 68 via an intercooler 48 and a pipeline 73, and the outlet of the second passage 72 of the second heat exchanger 68 communicates with the inlet of an expansion turbine 74, whose outlet is connected to the inlet of the second passage 24 of the first heat exchanger 20 via the pipeline 30. The third compressor 64 is driven by the expansion turbine 74.

Ifølge oppfinnelsen strømmer avkok fra tanken 2 til den første kompressor 12 via en første passasje 111 av en ytterligere eller tredje kjøler eller varmeveksler 110 og en rørledning 113 som er anordnet mellom denne varmeveksler 110 og den første kompressor 12. According to the invention, decoction flows from the tank 2 to the first compressor 12 via a first passage 111 of a further or third cooler or heat exchanger 110 and a pipeline 113 which is arranged between this heat exchanger 110 and the first compressor 12.

En rørledning 100 er tilkoblet utløpet av den annen varmeveksler 68 og er forbundet med innløpet av en annen passasje 112 av den ytterligere varmeveksler 110 via en reguleringsventil 104 og en rørledning 108. A pipeline 100 is connected to the outlet of the second heat exchanger 68 and is connected to the inlet of another passage 112 of the further heat exchanger 110 via a control valve 104 and a pipeline 108.

Utløpet av den annen passasje 112 av den ytterligere varmeveksler 110 er via en rørledning 114 forbundet med innløpet av den annen kompressor 58 og/eller via en rørledning 116, som er tegnet med stiplet strek, med den rørledning 28 som forbinder den annen passasje 24 av den første varmeveksler 20 med den første passasje 66 av den annen varmeveksler 68. The outlet of the second passage 112 of the additional heat exchanger 110 is connected via a pipeline 114 to the inlet of the second compressor 58 and/or via a pipeline 116, which is drawn with a dashed line, to the pipeline 28 which connects the second passage 24 of the first heat exchanger 20 with the first passage 66 of the second heat exchanger 68.

For avføling av temperaturen på avkoket i innløpet til den første kompressor 12, er det på rørledningen 113 mellom den ytterligere varmeveksler 110 og den første kompressor 12 montert en temperatursensor 120 som er innrettet til å avgi signaler vedrørende verdien av denne temperatur til en styreinnretning 121. Styreinnretningen 121 er i sin tur innrettet til å avgi signaler til reguleringsventilen 104 for styring av strømmen av kjølemiddel fra kjøleanlegget 26 til den annen passasje 112 av den ytterligere varmeveksler 110 for derved å søke å holde temperaturen på avkoket i rørledningen 113 konstant. For sensing the temperature of the decoction in the inlet to the first compressor 12, a temperature sensor 120 is mounted on the pipeline 113 between the additional heat exchanger 110 and the first compressor 12, which is arranged to transmit signals regarding the value of this temperature to a control device 121. The control device 121 is in turn arranged to issue signals to the control valve 104 for controlling the flow of coolant from the cooling system 26 to the second passage 112 of the further heat exchanger 110 in order to thereby seek to keep the temperature of the decoction in the pipeline 113 constant.

Det vil forstås at temperatursensoren 120 kan være innrettet til å sende elektriske signaler til styreinnretningen 121 som i sin tur kan sende elektriske signaler til reguleringsventilen 104, men temperatursensoren og styreinnretningen kan f.eks. i stedet være mekaniske og innrettet til mekanisk styring av reguleringsventilen. It will be understood that the temperature sensor 120 can be arranged to send electrical signals to the control device 121 which in turn can send electrical signals to the control valve 104, but the temperature sensor and the control device can e.g. instead, be mechanical and designed for mechanical control of the control valve.

Selv om det avkok som strømmer inn i rørledningen 8 kan ha en sterkt varierende temperatur, blir det ved oppfinnelsen således sikret at temperaturen på avkoket ved innløpet av den første kompressor 12 blir holdt på en stabil, liten verdi, slik at det blir sikret optimale driftsbetingelser for anlegget. Although the decoction that flows into the pipeline 8 can have a greatly varying temperature, the invention thus ensures that the temperature of the decoction at the inlet of the first compressor 12 is kept at a stable, small value, so that optimal operating conditions are ensured for the facility.
