Rondedzero yemaitiro ega ega chikamu cheBOG reliquefying chirimwa

Iyo BOG ye LNG yekuchengetera tangi inopinda mu liquefaction inotonhora bhokisi mushure mekudzvanywa uye metering, yakatonhodzwa, yakanyungudutswa, uye yakanyungudika muplate-fin heat exchanger, uye inodzokera kuLNG yekuchengetera tangi seLNG chigadzirwa mushure mekugwinha.

Nzira huru yetekinoroji yechishandiso ichi ndeiyi:

MRC (mixed refrigerant) cycle refrigeration process inoshandiswa kunyungudutsa iyo yose yakacheneswa BOG gasi;

Iyi process system inosanganisira:

Kudyisa gasi kusefa kuparadzaniswa uye kudzvanywa unit;

LNG liquefaction system;

Mixed refrigerant refrigeration unit;

1) Kudyisa gasi kupatsanurwa uye kudzvinyirira unit

1) Tsanangudzo yemaitiro

BOG gasi rinopinda mumhepo inopisa gasifier uye kudyisa gasi kupisa exchanger, uye mushure mekumanikidza, kupatsanurwa, uye metering, inopinda yakadzika liquefaction system.

Iyo huru process midziyo ndeyemhepo inopisa gasifier, yekudyisa gasi kupisa inotsinhanisa, inoyerera mita, inosimudzira compressor unit, nezvimwe.

2)Liquefaction unit

1) Tsanangudzo yemaitiro

Usati wapinda muLiquefaction unit, iyo purge gasi inofanirwa kuongororwa kuti ive nechokwadi chekuti mvura yemukati, yakazara aromatics uye mercury zvirimo zvinosangana nezvinodiwa zvekupinda mukati.Liquefaction unit.

Iyo yakacheneswa BOG gasi rinotanga kupinda mune liquefaction heat exchanger mubhokisi rinotonhora, rinotonhodzwa zvishoma nezvishoma nekudzoka kwakadzika-tembiricha yakasanganiswa refrigerant, uyezve supercooled kusvika -162°C, wobva wapinda muparadziri yeLNG kuti uwane zvigadzirwa zveLNG.

Chishandiso chikuru ibhokisi rinotonhora, iro rinonyanya kusanganisira kupisa kupisa kweplate, zvakasiyana-siyana zvinoparadzanisa, nezvimwe.

3) Yakasanganiswa refrigerant compression uye proportioning unit

1) Tsanangudzo yemaitiro

Iyo yakasanganiswa refrigerant yechigadzirwa ichi ichave yakagadzirwa methane yakacheneswa, nitrogen uye hydrocarbon refrigerants.

Refrigerant compression ine inopisa-yekupedzisira refrigerant compressor uye inotonhora-yekupedzisira refrigerant compressor. Iyo inopisa-yekupedzisira refrigerant compressor inonyanya kupa kutonhora kwepamusoro-tembiricha yekupedzisira, uye inotonhora-yekupedzisira refrigerant compressor inonyanya kupa kutonhora kweiyo yakaderera-tembiricha chikamu.

Midziyo mikuru ndeye refrigerant cycle compressor, refrigerant proportioning tank, nezvimwe.

2) Dhizaini paramita

Liquefaction capacity: 224.7 tons/d

Compressor Type: Screw Compressor

2 compressors (1 yakakwirira uye yakaderera tembiricha refrigerant compressor imwe neimwe)

Suction pressure 0.3MPa.G

Kusveta tembiricha 40. 0℃

Exhaust pressure 1.9MPa.G (ichireva kune yekubuda flange kweyekupedzisira inotonhorera)

Exhaust tembiricha 40°C(zvichireva kuburitsa flange kweyekupedzisira inotonhorera)

3) Adaptation range

50% ~ 110%.

4) Cold box heat unit

1) System basa

Usati watanga kwekutanga, zvakakosha kuomesa zvose BOG gasi kuyerera nzira uye refrigerant refrigeration kuyerera nzira yechigadzirwa.

Mushure mekushanda kwenguva refu kweiyo liquefaction inotonhora bhokisi, iyo yakasara kabhoni dhayimoni uye unyoro mune yakacheneswa BOG gasi ichaunganidza mune yakaderera-yekushisa chikamu che liquefaction cold box , zvichikonzera kuwedzera kupikisa uye kushandiswa kwesimba, uye zvinogonawo kukonzera liquefaction kutonhora. bhokisi kutadza kushanda zvakajairika. Naizvozvo, muAfter the duty cycle, iyo liquefaction inotonhora bhokisi ichadziya uye yakanyungudutswa neinodziya nitrogen kana BOG gasi.

2) Tsanangudzo yemaitiro

BOG gasi kubva kune nitrogen pombi network inodziya nemagetsi kusvika 60 ~ 70℃ , uye wobva wapinda kumberi nekumashure kuyerera kwegasi rekudya uye kumberi nekumashure kuyerera kwefiriji mune liquefaction inotonhora bhokisi yekudziya, uyezve inopisa kubva mubhokisi rinotonhora rinobuda.

Rongteng anoshanda negasi munda wemumusoro kurapwa, kucheneswa gasi, kupora LPG, LNG chirimwa uyegasi jenareta seti.
