Pfupiso yeIndustrial Glacial Acetic Acid Production uye Kucheneswa
Kugadzirwa nekucheneswa kweacetic acid mumaindasitiri kunotanga nekushandurwa kwezvinhu zvakagadziriswa—zvinowanzoitwa methanol kuburikidza necarbonylation kana bioconversion yebiomass—kuita crude acetic acid. Upstream processing inosanganisira reactors uko feedstock conversion inoitika. Catalysts dzinoshandiswa zvakanyanya, dzakadai se rhodium complexes, dzinobatsira methanol carbonylation inoshanda zvakanaka, zvichikonzera crude product ine mvura nezvimwe zvakasiyana-siyana.
Mushure mekusangana nechinhu ichi, musanganiswa wacho unopatsanurwa kutanga kuti ubvise zvinhu zvinorema kana zvisinganyunguduke. Mitsipa yeacetic acid isina kuchena, iyo ichiri kuchengetedza huwandu hwakawanda hwemvura uye tsvina isingafashaire zvakanyanya, inoendeswa kunocheneswa. Pano, maitiro acho anotarisana nemabasa ekubvisa mvura nemafuta kuti abvise tsvina uku achiwana acetic acid yakachena zvikuru.
Maitiro ekunyungudutsa acetic acid akakosha. Makoramu ekunyungudutsa—kunyanya matora emvura inoyerera—anobvisa mvura uye anogadzirisa huwandu hweacetic acid. Matora ekunyungudutsa anoshandisa counter-current vapor-liquid contact patembiricha dzakadzorwa uye kumanikidzwa kuti aendese mvura kumusoro kwekoramu uku achichengetedza acetic acid pasi. Makoramu ekunyungudutsa anoitwa ne vacuum, zvichiita kuti acetic acid iparadzaniswe kubva mutsvina inofashaira zvishoma uye acetic anhydride nekuderedza njodzi yekuora kwekupisa. Kudzora kumanikidzwa kwemaitiro muzvikamu izvi zvakakosha: kumanikidzwa kwakaderera kunoderedza mapoinzi ekufashaira, kuderedza kudiwa kwesimba uye kuchengetedza mhando yechigadzirwa sezvakaratidzwa muongororo dzehunyanzvi uye nhungamiro dzeindasitiri.

Nekubatanidza kuyerwa kwedhijitari nekukurumidza, kugara kwenguva refu kwemakemikari, uye kubatanidzwa kwepuratifomu yekubatanidza, Lonnmeter inline pressure transmitter chishandiso chakarurama uye chakavimbika chekuyera kumanikidzwa kwepamusoro mukushandiswa kwemakemikari—kusanganisira nzira dzakaoma dzekudzora kumanikidzwa kweacetic acid process.
Kubudirira uye Kuderedza Mari Nezvishandiso Zvemazuva Ano Zviri Mukati
Zvishandiso zvemazuva ano zvemukati, zvakaita seLonnmeter series, zvakachinja zvakanyanya kugadzirwa nekucheneswa kweacetic acid yechando. Nekubatanidza zvizere inline density metres, concentration sensors, uye level transmitters mu distillation columns uye dehydration towers, zvirimwa zvinowana kushanda kwakasimba uye mitengo yakaderera mumabasa akasiyana-siyana.
Kugadzikana kwemaitiro kunokonzerwa nekuyera kwakananga mukati menguva chaiyo. NeLonnmeter density metres, mhinduro inoenderera mberi inoita kuti acetic acid distillation process optimization ibudirire nekuchengetedza mashandiro ekoramu mukati mezviyero zvakanaka. Kuwanda uye kuverenga kwehuwandu hwezvinhu zvinowanikwa ipapo, zvichibvumira masisitimu ekudzora kugadzirisa reflux ratios, kupisa, uye mamiriro evacuum, zvakakosha kuti mashandiro agare akasimba mu glacial acetic acid vacuum distillation techniques. Izvi zvinoguma nekuchinja kushoma, kudzora kwakasimba kwezvinodiwa zvechigadzirwa pamusoro nepazasi, uye njodzi shoma yekugadzira zvinhu zvisiri zvemhando yepamusoro.
Kudzora kwakasimba kunoshandurawo kuchengetedza simba kunoyerwa. Kudzora kwakanyatsojeka kwekumanikidzwa kwekoramu nekupisa zvinoreva kuti simba rinodiwa chete ndiro rinoshandiswa pakupfungaira nekuparadzanisa. Mukuita, kuyera mukati memutsara kunobvumira vanodzora kumanikidzwa kwemaitiro—vanotsigirwa nezvinobva muzvishandiso zvakaita sematransmitter ekumanikidza akagadzirwa achishandisa nzira dzakagadzirwa dzekudzora kumanikidzwa kwemaitiro eacetic acid—kuderedza kutenderera, nokudaro kudzivirira kushandiswa kwakanyanya kwepombi yekubvisa simba kana vacuum. Kuchengetedza simba kunobatanidzwa nekuderedzwa kwekugadzirwa kwemabatch asina kutsanangurwa. Kufamba kushoma kunoreva kuti zvinhu zvishoma zvinogadziriswazve kana kuraswa, zvichikanganisa zvakananga mari.
Kuongororwa kwekufanotaura kunogoneswa nezvishandiso izvi kunowedzera kurerutsa kugadziriswa. Inline density uye concentration metres, seLonnmeter series, inogara ichishuma hutano uye mamiriro ekugadzirisa. Vashandi vanowana yambiro yekutanga yekudonha kwesensor kana kusvibiswa, kunyanya kukosha panguva yekumhanya kwenguva refu mu vacuum distillation ye acetic acid concentration uye nhanho dzekushaya mvura. Kugadziriswa kunorongwa zvichienderana nemamiriro emuchina, kwete karenda yakatarwa, zvichideredza nguva isingatarisirwi yekushanda uye kuwedzera hupenyu hwezvinhu. Nekuda kweizvozvo, kugadzirisa matambudziko e acetic acid distillation systems kunova kwakarongeka, nekugadziriswa kushoma mushure mechokwadi.
Kuderedzwa kwemutengo kunosimbiswa nenzira dzakasiyana-siyana. Kuyera nekudzora panguva chaiyo kunobvisa kudiwa kwekutora sampuro nemaoko nguva nenguva, kuderedza zvinodiwa nevashandi uye njodzi yekutadza kubata sampuro.

Kupisa kwakaderera kunodiwa kudzivirira kuparara kweacetic acid nekupisa, kunyanya kana uchitarisa kuchena kwakanyanya. Mamiriro evacuum anodzorwa nokungwarira anoderedzawo kushandiswa kwesimba. Kushandisa ma inline pressure transmitters akarurama kunotsigira matekiniki e glacial acetic acid vacuum distillation nekuona kuti kudzvanywa kwakaderera kunochengetwa pasina kuchinja-chinja, nokudaro zvichidzivirira kunaka kwechigadzirwa uye kusimba kwemidziyo.
3. Ndezvipi zvakanakira kushandisa Rosemount 3051 differential pressure transmitter mumafekitori emakemikari?
Muchina weRosemount 3051 differential pressure transmitter unoshandiswa zvakanyanya mu acetic acid purification systems nekuda kwekururama kwayo, kuvimbika, uye kugadzikana. Unopa kuverenga kwekumanikidzwa panguva chaiyo uye kwakarurama izvo zvinotsigira kuyerwa kwekumanikidzwa kwepamusoro mukugadzirwa kwemakemikari. Izvi zvinovandudza kudzora maitiro mumakoramu ekudiridza nematombo emvura nekubatsira vashandi kuchengetedza ma profiles ekumanikidzwa akakodzera, nokudaro zvichiwedzera goho uye zvichideredza njodzi dzekutsauka kwesimba rine njodzi. Kuvimbika kunoderedzawo nguva dzekugadzirisa uye nguva dzisina kurongwa, zvichitsigira kushanda kwakachengeteka uye kwakanaka nguva dzose.
4. Ma inline pressure transmitters anofanira kuiswa kupi mu acetic acid distillation process?
Matransmita ekumanikidza anofanirwa kunge ari panzvimbo yakakodzera kuti abate mashandiro ekumanikidza akakosha panguva yekudiridza acetic acid. Zvinhu zvakakosha zvinosanganisira nzvimbo dzinobuda utsi pamusoro pemakoramu ekudiridza, zvinobatanidza zvinopa simba remutsi we reboiler, nzvimbo dzinopinda macolumn feed, uye pamisoro nemiswe yemakoramu. Kuiswa kwakakodzera kunoita kuti munhu azive panguva chaiyo nezvekuchinja kwedzvinyiriro kunogona kuratidza kusagadzikana, kudonha kwemvura, kana kusvibiswa, zvichiita kuti pave nekukasira kugadzirisa nekugadzirisa mhando yechigadzirwa.
5Kuyerwa kwekumanikidzwa kunoita basa rei mukugadzirisa matambudziko e acetic acid distillation systems?
Kuyera kumanikidzwa kwakakosha pakugadzirisa masisitimu ekunyungudutsa acetic acid. Ruzivo rwakarurama uye runokurumidza kubva kuma inline pressure transmitters runoratidza matambudziko akadai sekubuda kwevacuum, kusawirirana kwemutsi, kana kufashamira kwe column. Semuenzaniso, kudzikira kwekumanikidzwa kwe column head kunogona kuratidza kubuda kwemhepo, nepo kumanikidzwa kwakanyanya kusingatarisirwi kunogona kuratidza kusvibiswa kana kusashanda zvakanaka kwe reboiler. Kuziva nekukurumidza matambudziko akadaro kunoita kuti glacial acetic acid irambe ichibuda uye yakachena, kunodzivirira nguva yakareba yekushanda, uye kuwedzera hupenyu hwemidziyo - zvese zvakakosha mumabasa ekugadzirisa uye kugadzirisa acetic acid.
