Tsib-ntauwd peb-txiaj ntsig yog thev naus laus zis txuag hluav taws xob tshiab tau qhia ua lub hauv paus ntawm ib txwm muaj tsib-ntau qhov sib txawv ntawm qhov siab sib txawv, uas yog siv rau kev tsim cov qib cawv zoo. Cov cuab yeej tseem ceeb ntawm cov tsoos tsib-pej thuam sib txawv qhov siab suav nrog cov pej thuam zom cov nyom, ntauwd ua kom tawg, txhim kho ntauwd, ntauwd methanol, thiab ntauwd tsis huv. Cov txheej txheem cua sov yog tias lub tsev kho kom zoo nkauj thiab ntauwd ua kom sov tau ua kom sov los ntawm thawj lub zog dhau los ntawm lub reboiler, thiab lub kho kom zoo nkauj ntauwd caw cov pa ua kom sov mus rau ntauwd crude distillation los ntawm lub reboiler. Lub tshuab ua kom dej ntau ntxiv ua kua dej ua kom sov mus rau ntauwd methanol los ntawm lub reboiler. Lub pej thuam tsis huv siv cov pa ncaj qha los muab cov cua sov ncaj qha, thiab kev siv lub zog loj yog qhov loj. Cov cuab yeej tseem ceeb ntawm tsib-kab lus peb-cuam tshuam qhov sib txawv ntawm qhov siab sib txawv tseem yog cov pej thuam zom cov nyom, ntauwd sib tov, txhim kho ntauwd, ntauwd methanol, thiab ntauwd tsis huv.

Qhov thib ob, tus yam ntxwv txheej txheem

1. Peb-txheej txheej txheej txheej cua sov ua kom sov ntauwd ntau dua, de-methanol ntauwd, ntauwd tsis huv, thiab tom qab ntawd ua kom cov pej thuam thiab de-methanol ntauwd ua kom cua sov ntau ntau ntau ntau kom txo cov dej kom tsawg. Kev tsim cov tons ntawm qib cawv zoo tshaj yog 2.2 tons.

2. Ntu degassing thiab cov khoom sib cais tau teeb tsa nyob rau sab saud ntawm cov pej thuam cov roj av txhawm rau txhawm rau txo cov khoom tsis huv xws li cov khib nyiab uas muaj nyob hauv cov cawv nyoos nkag mus rau hauv cov txheej txheem kho, yog li txhim kho kev huv ntawm cov cawv nyoos.

3. Lub tshuab ua kom lub tshuab ua kom lub tshuab ua kom rov ua dua tshiab tau txais kev lees paub thev naus laus zis ntawm thermosyphon kev hloov cua sov es tsis txhob siv cov cua sov tso cua txias, thiab lub zog txuag hluav taws xob zoo kawg li, thiab qhov tshwm sim thaiv ntawm reboiler tshav kub hloov pauv raj raug tshem tawm.

4. Cov tooj liab piper ntim tau ntxiv rau hauv cov txheej txheem txhawm rau txhawm rau txhim kho qhov saj zoo ntawm cov cawv tiav.

Thib peb, txheej txheem cua sov

Tus yuam sij rau kev txuag hluav taws xob ntawm cov txheej txheem no yog nws hom cua sov, nyob rau hauv uas lub zog ua ntej dhau los ntawm lub reboiler kom sov cov kab lus kho. Lub tshuab ua kom dej ntau dhau los ua kua nkag mus rau kem methanol thiab ntauwd dilution los ntawm cov methanol kem reboiler thiab cov kem dilution reboiler. Ntauwd dilution thiab methanol ntauwd wine vapor tau faib ua ntu dhau los ntawm cov khoom sib tsoo cov khoom sib xyaw ua kom rov ua dua tshiab A thiab B txhawm rau muab ntauwd sib txawv. Lub tsev tso dej tso dej ntau dhau los ua dej ntws tawm kom muab cov pej thuam tsis huv. Ib tus pej thuam nkag mus rau hauv chav ua pa thiab tsib lub tsev kom ua tiav peb qhov kev sib txuas ua kom sov kom ua tiav lub hom phiaj txuag hluav taws xob. Kev tsim cov tons ntawm qib cawv zoo tshaj yog 2.2 tons.

Plaub, cov khoom hloov pauv

Cov kua txiv hmab txiv ntoo uas tau fermented yog pub los ntawm sab saum toj ntawm cov khoom sib xyaw ua ke tom qab ob theem ntawm preheating. Cov cawv ua cawv nyob rau sab saum toj ntawm cov pej thuam ua kom tawg ua kua tau muab zom ua ke thiab tom qab ntawd ua kom huv thiab ua kom huv mus rau hauv cov tsev sib tov kom txo cov cawv nyoos mus rau 12-18% (v/v). Cov cawv hauv qab yog preheated thiab tom qab ntawd nkag mus rau lub khoos phis tawj kho qhov rooj ntawm kab sab saud ntawm kab sib txawv. Cov cawv (96% (v/v)) raug tshem tawm mus rau kab de-methanol txhawm rau tshem tawm lwm yam tsis huv xws li methanol, thiab cawv cawv tiav yog tshem tawm hauv qab.

Lwm yam zoo

1. Hais txog kev txuag hluav taws xob, lub thermosiphon reboiler cycle cua sov txoj kev hloov pauv qhov kev tso cua sov kom txias, thiab siv peb cov cuab yeej thev naus laus zis los tiv thaiv kev thaiv ntawm lub reboiler hloov pauv cua sov raj. Kev haus cawv ib tuj ntawm cawv yog 20kwh. Piv nrog rau kev txhim kho thawj tsib lub tsev sib txawv sib txawv siab sib txawv 40-45kwh, lub zog txuag yog 50%, uas zam kev saib xyuas ntawm lub reboiler yuam kev tso lub twj tso kua mis thiab ua kom lub neej kev pab cuam ntawm reboiler ntev.

2. Kev kho cov cawv tsis huv: Cov cawv tsis huv los ntawm cov pej thuam ua kom tawg, ntauwd ua kom tawg, ntauwd methanol, thiab lwm yam, thiab cov cawv txiv hmab los ntawm cov fusel roj cais cais nkag mus rau hauv lub tsev tsis huv, thiab cov cawv cawv raug rho tawm tom qab lub tsev lim dej tsis huv lawm. Cov roj fusel tau muab rho tawm, thiab cov cawv nyoos nyoos tawm los ntawm kab sab saud yog tom qab ntawd dhau mus rau qhov chaw sib tsoo kom ua rau cov qib cawv tau txais txiaj ntsig zoo.

3. Hais txog kev txhim kho cawv kom zoo, ntxiv rau kev ntsuas thev naus laus zis, cov qauv ntawm cov cuab yeej kuj tau txhim kho. Ntauwd ua kom cov nyom tsis zoo yog nruab nrog cov cuab yeej ua kom cov cawv tsis huv, thiab ntauwd kev sib cais tau muab nrog cov tooj liab muab cov tshuaj sulfur tshem tawm cov cuab yeej kom ntseeg tau tias qhov huv thiab saj ntawm cawv.

Thib rau, qib kawm tau zoo haus cawv thiab siv cov lus sib piv zoo.
