LNG/LPG Medium Compatibility & Installation Guide
Tshooj lus no muab nruab nrab -cov lus qhia tshwj xeeb rau kev xaiv thiab txhim kho qhov ntsuas ntawm qhov sib txawv cryogenic liquefied gas cia systems. Txhua qhov nruab nrab muaj qhov sib txawv ntawm qhov kub thiab txias, vapor siab, ntom thiab corrosivity, uas ncaj qha cuam tshuam rau cov khoom siv ntub dej, qhov ntsuas flange thiab kev teeb tsa.
Medium Property Comparison & Kev Xaiv Khoom
| Cryogenic Medium | Boiling Point ntawm 1 atm | Hom Cia Siab | Pom zoo Wetted Khoom | Ntsiab Lus Xaiv |
|---|---|---|---|---|
| LNG (Liquefied Natural Gas) | -162 degree | Atmospheric / qis siab | 316L qis-temp steel, Titanium | methane- nplua nuj, tsawg ntom (~0.42 g / cm³), yuav tsum tau kuaj xyuas qhov ceev tsawg kawg nkaus |
| LPG (Propane / Butane) | -42℃/ -0.5 degree | 0.5 ~ 1.6 MPa | 316 L, 304 SWB | Siab dua vapor siab, siab - ntsuas flange yuav tsum tau; tsis txias li LNG |
| Liquid Ammonia (NH₃) | -33 degree | 0.8 ~ 1.5 MPa | titanium, 316 TSI | Kev nyuaj siab corrosion ntawm tus qauv 316L; titanium wetted qhov chaw pom zoo |
| Liquid Ethylene (C₂H₄) | -104 degree | Atmospheric / qis siab | 316L qis-temp steel, Inconel 625 | Cryogenic kub nruab nrab; txheeb xyuas flap sib dhos txias ntsuas |

Hom Installation Nozzle Configuration
Rau LNG thiab LPG cia tso tsheb hlau luam, qhov ntsuas feem ntau yog sab -mounted nrog rau sab sauv thiab qis nozzle txuas ncaj qha rau lub plhaub tank. Pom zoo configuration:
- Upper nozzle (gas theem):DN50 / DN80 cryogenic flange, nyob rau hauv 100-200 mm hauv qab tank siab tshaj kua theem
- Lower nozzle (kua theem):DN50 / DN80 cryogenic flange, nyob 100-200 hli saum lub tank hauv qab
- Nozzle extension:150-300 mm ncua caj dab pom zoo kom txo cov cua kub ntawm lub tank phab ntsa mus rau qhov ntsuas chamber
- Isolation li qub:Cryogenic pob li qub lossis rooj vag li qub xaiv tau ntawm ob lub nozzles rau kev saib xyuas kev sib cais
- Drain Port:Txheem 1/2 "NPT ntws valve ntawm chamber hauv qab rau kev tshem tawm thiab cov kua dej seem
Kev Nyab Xeeb & Kev Ceeb Toom
- Electrostatic grounding:Lub ntsuas chamber thiab tag nrho cov hlau flanges yuav tsum tau hluav taws xob sib txuas rau lub tank hauv av. LNG thiab LPG tsis yog -cov kua dej ua kua; static charge accumululation thaum lub sij hawm filling tuaj yeem tsim teeb meem hluav taws xob.
- Kev tawg- pov thawj zoning:LNG cia tso tsheb hlau luam feem ntau yog cais raws li Zone 1 (hauv 3 m ntawm lub tank qhib) lossis Zone 2 (3-7.5 m). Tag nrho cov khoom siv hluav taws xob yuav tsum muaj daim ntawv pov thawj Ex tsim nyog rau thaj chaw teeb tsa.
- Kev tiv thaiv thermal shock:Thaum lub sij hawm pib cooldown, qhia cov kua cryogenic maj mam kom tsis txhob thermal shock ntawm chamber thiab flanges. Kev hloov pauv ceev ceev los ntawm ambient mus rau -162℃tuaj yeem ua rau lub foob tsis ua haujlwm.
- Maintenance Access:Khaws qhov tsawg kawg nkaus 500 hli qhov chaw ntshiab nyob rau hauv pem hauv ntej ntawm qhov taw qhia nrov plig plawg rau kev nyeem ntawv pom thiab 800 hli saum lub ntsuas ntsuas rau kev tshem tawm thiab ntsuas ntsuas.
