【Kev Taw Qhia】 Thaum Lub Xya Hli, cov khoom lag luam hauv cov saw hlau acetone feem ntau pom tias muaj kev poob qis. Kev tsis sib npaug ntawm kev muab khoom thiab kev thov thiab kev sib kis tus nqi tsis zoo tseem yog qhov ua rau cov nqi lag luam poob qis. Txawm li cas los xij, txawm hais tias tag nrho cov khoom lag luam hauv cov saw hlau muaj kev poob qis, tsuas yog kev nthuav dav me ntsis ntawm kev lag luam poob nyiaj, cov txiaj ntsig ntawm MMA thiab isopropanol tseem nyob saum kab breakeven (txawm hais tias lawv cov txiaj ntsig kuj raug nias ntau heev), thaum tag nrho lwm cov khoom lag luam tseem nyob hauv qab kab breakeven.
Cov khoom lag luam hauv cov saw hlau acetone tau qhia txog kev poob qis hauv lub Xya Hli
Cov khoom lag luam hauv cov saw hlau acetone tau poob qis rau lub hlis no. Kev tsis sib npaug ntawm kev muab khoom thiab kev thov thiab kev sib kis tus nqi tsis zoo yog cov ua rau kev lag luam poob qis. Hais txog qhov kev poob qis, acetone pom kev poob qis txhua hli ntawm kwv yees li 9.25%, qeb duas thawj zaug hauv cov saw hlau kev lag luam. Kev muab khoom lag luam acetone hauv tsev hauv lub Xya Hli tau qhia txog kev nce ntxiv: ntawm ib sab tes, qee lub tuam txhab uas tau ncua kev tsim khoom ua ntej rov pib dua, xws li Yangzhou Shiyou; ntawm qhov tod tes, Zhenhai Refining & Chemical tau pib muag khoom sab nraud thaum Lub Xya Hli 10, uas ua rau cov neeg sab hauv kev lag luam chim siab, thawb qhov kev sib tham hauv kev lag luam poob qis. Txawm li cas los xij, thaum tus nqi txuas ntxiv poob qis, cov neeg tuav khoom ntsib kev nyuaj siab ntawm tus nqi, thiab qee tus sim tsa lawv cov lus hais, tab sis qhov kev nce siab tsis muaj kev ruaj khov, thiab cov ntim kev lag luam tsis tau muab kev txhawb nqa.
Cov khoom lag luam acetone hauv qab tau qhia txog kev poob qis. Ntawm lawv, qhov kev poob qis txhua hli hauv tus nqi nruab nrab ntawm bisphenol A, isopropanol, thiab MIBK txhua tus tshaj 5%, ntawm -5.02%, -5.95%, thiab -5.46% feem. Tus nqi ntawm cov khoom siv raw phenol thiab acetone ob leeg tau nqis qis, yog li sab nqi tsis tau txhawb nqa kev lag luam bisphenol A. Tsis tas li ntawd, tus nqi ua haujlwm ntawm kev lag luam bisphenol A tseem siab, tab sis kev thov ua raws li qhov tsis muaj zog; tawm tsam keeb kwm yav dhau los ntawm kev muab khoom thiab kev thov, qhov kev poob qis ntawm kev lag luam tau hnyav zuj zus.
Txawm hais tias kev ua lag luam isopropanol hauv lub hli tau txais kev txhawb nqa zoo los ntawm cov yam xws li Ningbo Juhua kaw, Dalian Hengli txo qhov kev thauj khoom, thiab kev ncua sijhawm hauv kev lag luam hauv tsev, sab kev thov tsis muaj zog. Ntxiv mus, cov nqi khoom siv raw acetone poob qis dua 5,000 yuan / ton, ua rau cov neeg ua haujlwm hauv kev lag luam tsis muaj kev ntseeg siab txaus, uas feem ntau muag ntawm tus nqi qis dua, tab sis cov ntim kev lag luam tsis muaj kev txhawb nqa, ua rau kev lag luam poob qis.
Cov khoom siv ntawm MIBK tseem txaus, nrog rau qee lub Hoobkas tseem ntsib kev nyuaj siab rau kev xa khoom. Cov lus hais tau txo qis nrog chav rau kev sib tham txog kev lag luam tiag tiag, thaum qhov kev thov hauv qab tsis hloov pauv, ua rau cov nqi lag luam poob qis. Tus nqi nruab nrab ntawm MMA hauv kev lag luam tseem ceeb ntawm Sab Hnub Tuaj Tuam Tshoj poob qis dua 10,000-yuan lub hlis no, nrog rau kev poob qis txhua hli ntawm 4.31% ntawm tus nqi nruab nrab txhua hli. Kev thov txo qis thaum lub caij so yog qhov ua rau kev poob qis hauv kev lag luam MMA.
Kev khwv tau nyiaj ntawm cov khoom lag luam feem ntau tsis muaj zog
Thaum Lub Xya Hli, qhov txiaj ntsig ntawm cov khoom lag luam hauv cov saw hlau acetone feem ntau tsis muaj zog. Tam sim no, feem ntau cov khoom lag luam hauv cov saw hlau kev lag luam nyob rau hauv lub xeev ntawm kev muab khoom txaus tab sis tsis txaus qhov kev thov ua raws li; ua ke nrog kev sib kis tus nqi tsis zoo, cov no tau dhau los ua qhov laj thawj rau kev poob ntawm cov khoom lag luam hauv cov saw hlau. Thaum lub hli, tsuas yog MMA thiab isopropanol tswj cov txiaj ntsig saum toj no kab breakeven, thaum tag nrho lwm cov khoom lag luam nyob hauv qab nws. Lub hli no, cov txiaj ntsig tag nrho ntawm cov saw hlau kev lag luam tseem tseem nyob hauv kev lag luam MMA, nrog rau cov txiaj ntsig tag nrho theoretical ntawm kwv yees li 312 yuan / ton, thaum cov txiaj ntsig tag nrho theoretical poob ntawm MIBK kev lag luam nthuav dav mus rau 1,790 yuan / ton.
Cov khoom lag luam hauv cov saw hlau acetone kev lag luam yuav ua haujlwm nyob rau hauv qhov ntau ntawm kev hloov pauv hauv lub Yim Hli
Xav tias cov khoom lag luam hauv cov saw hlau acetone yuav ua haujlwm nyob rau hauv qhov kev hloov pauv me me hauv lub Yim Hli. Hauv kaum hnub thawj zaug ntawm lub Yim Hli, cov khoom lag luam feem ntau yuav tsom mus rau kev zom cov ntawv cog lus ntev, nrog rau kev txaus siab tsawg rau kev yuav khoom hauv kev ua lag luam. Cov ntim kev lag luam yuav muab kev txhawb nqa tsawg rau cov khoom lag luam. Hauv nruab nrab thiab lig kaum hnub, thaum qee qhov kev npaj yuav khoom hauv qab thiab "Lub Cuaj Hli Kub" kev lag luam nce ntxiv, qee qhov kev thov kawg yuav rov qab los, thiab cov ntim kev lag luam yuav tsim kev txhawb nqa rau cov nqi. Txawm li cas los xij, hais txog qhov kev hloov pauv ntawm lub hlis no, kev cia siab tseem tsawg.
