Tom qab cov benzene/hydrobenzene ntshiab poob rau 6000 yuan cim, tsav los ntawm kev yooj yim ntawm txoj cai hauv tebchaws, qhov kev xav ntawm kev ua lag luam tau hloov me ntsis, qee tus tub luam thiab kev yuav khoom pheej yig, cov ntim pauv benzene/hydrobenzene ntshiab, txhawb nqa tus nqi nce, txij li Lub Rau Hli 16, Shandong roj benzene tus nqi yog li 6220 yuan / ton, nce ntawm 80-140 yuan / ton. Tso lub hauv paus rau lub lim tiam no hydrobenzene rov qab los.

Tam sim no, qhov kev tsom mus rau kev ua lag luam yog nyob rau qhov nce ntawm kev siv styrene muaj peev xwm, qhov poob qis ntawm kev ua haujlwm ntawm phenol thiab kev nce ntawm kev xa khoom benzene ntshiab.

1, kev siv cov peev xwm styrene tseem ceeb hauv qab yuav nce ntxiv

Ib feem ntawm lub Hoobkas styrene uas raug nres lawm npaj yuav rov pib dua, ua ke nrog Zhejiang Petrochemical 600,000 tons ntawm cov khoom siv tau muab tso rau thaum 15 teev sawv ntxov rau lub Rau Hli 16, los ntawm Tuam Tshoj cov ntaub ntawv tsim khoom thiab kev siv styrene xav tias yuav txhim kho tag nrho. Kev siv styrene muaj peev xwm yuav ua rau muaj kev thov benzene ntshiab ntau ntxiv, yuav ua rau muaj kev siv benzene ntshiab ntau ntxiv, tab sis tom qab kev nce ntawm styrene kev ua haujlwm, nws tseem tsim nyog yuav tsum tau them sai sai rau qhov sib phim ntawm styrene, yog tias qhov sib phim ntawm styrene nyuaj rau kev ua tiav kev txhim kho sib xws, styrene ntsib qhov xwm txheej ntawm kev muab khoom thiab kev thov txo qis, tom qab tag nrho, styrene yuav maj mam nkag mus rau qhov kub siab tshaj plaws.

2, downstream phenol ketone kev khiav hauj lwm tus nqi tseem poob qis

Tsis ntev los no cov lag luam phenol ketone downstream pib ntawm theem ntawm 69%, hli-rau-hli -1%. Ntawm lawv, thaum lub sijhawm kaw thiab txij nkawm ntawm Jiangsu Ruiheng, Shanghai Sisar thiab Gaoqiao Petrochemical phenol ketone units, Shenghong refining phenol ketone units muaj kev ua haujlwm tsis zoo, yog li qhov kev ua haujlwm phenol ketone txuas ntxiv poob qis, txo kev siv benzene ntshiab, thiab tsim cov lus tawm tswv yim tsis zoo rau benzene / hydrobenzene ntshiab.

3, Tuam Tshoj cov khoom xa tuaj benzene ntshiab yuav tsum nce ntxiv

Thaum kawg ntawm lub sijhawm concentration ntawm kev saib xyuas txawv teb chaws, thiab qhov octane tus nqi logic tau poob qis, Asia cov benzene ntshiab yuav tsum nkag mus rau hauv Suav teb rau kev zom, thiab nws xav tias cov khoom xa tuaj benzene ntshiab hauv tsev yuav nce ntxiv, ua rau muaj kev nce ntxiv ntawm cov khoom xa tuaj benzene ntshiab hauv tsev, los ntawm qhov pom ntawm kev xa khoom txhua hli, kev xa khoom lossis los ntawm 200,000 tons txog 300,000 tons ntawm qhov ntsuas.

Ntxiv mus, Hainan Refining thiab Chemical tshiab 2.6 lab tons ntawm kev hloov pauv pub, CNOOC Huizhou tshiab 1.3 lab tons ntawm kev hloov pauv cov khoom tsim tawm ntawm cov aromatics thiab kev tsis sib npaug yuav tsum tau muab tso rau hauv pub tom qab, cov khoom siv hauv tsev ntawm benzene ntshiab nce ntxiv.

Nyob rau lub sijhawm luv luv, uas cuam tshuam nrog kev rov ua dua ib zaug thaum kawg ntawm lub hlis, nws xav tias qhov chaw yuav khoom ntawm benzene / hydrobenzene ntshiab yuav raug txhim kho, thiab tus nqi ntawm hydrobenzene yuav ruaj khov thiab rov qab los, tab sis qhov siab thiab lub zog rov qab los raug txwv, vim tias kev ua lag luam tseem nyob hauv qhov xov xwm tsis zoo, thiab kab nruab nrab thiab ntev raug kho nrog cov tswv yim khoob.
