Vim li cas Plhaub -thiab- tube Exchangers tsim nyog rau Kev Pabcuam Roj Hnyav?

Plhaub-thiab-tube heat exchangers yog tshwj xeeb tshaj yog haum rau hnyav hnyav kev pab cuam vim hais tias lawv tsim thiab kev khiav hauj lwm yam ntxwv phim cov kev cov nyom ntawm kev tuav siab -viscosity, fouling, thiab siab -kub kua. Cov laj thawj tseem ceeb suav nrog:

1. Muaj peev xwm tuav cov kua dej viscosity siab

Cov roj hnyav muaj viscosity siab, uas txo cov cua kub thiab hloov pauv hauv ntau hom kev sib hloov. Plhaub-thiab- tube exchangers:

Tso cai rau cov raj loj dua kom txo qis kev poob siab

Muaj peev xwm ua haujlwm ntawm cov lej Reynolds siab dua nrog cov nrawm tsim nyog

Ua haujlwm ruaj khov txawm tias cov roj viscosity hloov nrog kub

 

2. Muaj peev xwm kub thiab siab

Cov kev pabcuam roj hnyav feem ntau suav nrog qhov kub siab kom txo cov viscosity:

Plhaub-thiab- tube exchangers yog mechanically robust

Yooj yim tsim rau kev kub siab thiab kub ua haujlwm

Haum rau hluav taws kub cua sov downstream, lub tshuab nqus tsev residue, thiab bitumen kev pab cuam

 

3. Superior Fouling kam rau ua

Cov roj hnyav zoo li foul vim asphaltenes, coke tsim, thiab impurities:

Cov raj ncaj tuaj yeem raug kho kom huv (rodding, hydro-jetting)

Fouling-cov layouts tiv taus thiab qis shear designs tuaj yeem siv tau

Fouling margins tuaj yeem suav nrog yam tsis muaj kev cuam tshuam kev ncaj ncees

 

4. Cov kev xaiv tsim kho tshuab yooj yim

Plhaub-thiab- tube exchangers muaj ntau yam kev teeb tsa haum rau cov roj hnyav:

Kho cov ntawv raj, U-tube, lossis ntab taub hau tsim

Tsawg-siab-poob plhaub- sab tsim

Muaj peev xwm ua kom haum thermal expansion tshwm sim los ntawm kev kub siab gradients

 

5. Cov khoom siv dav dav

Cov roj hnyav tuaj yeem muaj cov sulfur, acids, lossis corrosive compounds:

Carbon steel, qis- alloy steel, stainless hlau, thiab Cr-Mo alloys muaj

Cladding lossis overlay welding tuaj yeem siv rau kev tiv thaiv corrosion

Cov ntaub ntawv tuaj yeem xaiv kom sib npaug ntawm tus nqi thiab kav ntev

 

6. Kev tshuaj xyuas thiab kev saib xyuas yooj yim

Rau cov roj hnyav hnyav, lub sijhawm poob qis yog kim:

Tube pob khoom tuaj yeem raug tshem tawm thiab tshuaj xyuas

Cov leeg leeg tuaj yeem txuas lossis hloov pauv

Kev kho yuav ua tau thaum lub sij hawm refinery turnarounds

 

7. Kev ua haujlwm ruaj khov nyob rau hauv kev ua haujlwm sib txawv

Cov roj hnyav hnyav hloov pauv nrog qhov kub thiab txias:

Plhaub-thiab- tube exchangers zam qhov kev hloov pauv loj

Kev ua tau zoo degradation yog maj mam es tsis yog tam sim ntawd

Zoo haum rau kev ua haujlwm tas mus li, hauv paus - thauj khoom lag luam

 

8. Pov thawj Technology hauv Heavy Oil Industries

Plhaub-thiab- tube exchangers muaj ntau xyoo ntawm kev ua haujlwm tiav hauv:

Refineries (nqus residue, visbreaker, ncua coking pub)

Bitumen thiab asphalt ua

Heavy crude preheating

Petrochemical thiab chemical nroj tsuag

 

Cov ntsiab lus

Plhaub-thiab-tube heat exchangers yog qhov zoo tagnrho rau kev pabcuam roj hnyav vim tias lawv muab cov khoom siv dag zog, fouling kam rau ua, thermal yooj, thiab yooj yim ntawm kev saib xyuas. Lawv adaptability rau cov txheej txheem hnyav ua rau lawv nyiam thiab txhim khu kev qha kev daws teeb meem rau hnyav, viscous, thiab fouling oil applications.
