Description

PROCESS FOR TREATMENT OF A SODIUM SULFATE CONTAINING REESÉÜUE PROCESS STREAh/i OF A BATTERY PROCESS Field of the invention The present invention relates to a process for providing value adding products from a residue process stream from a battery production process. Background An increased awareness of ciintate change and the iimited suppiy of fossii fueis has boosted the search aiternative energy sources for eg. operation of vehicies. The dentand for batteries is growing fast. This rneans aiso that the emissions, soiid and iiouid residues from battery production increases. Recyciing, and materiai optimization has titus become a reievaitt issue in recent years.
Battery rnanufacturing industry is working continuousiy to rninimize residue provision, and aim to recycie of process essentiai chemicais iike cohait, iithium and rnanganese which aid to reduce the taciiitys operating costs. Residues from a battery manufacturing process may be aoueous Wastewater streams, arnmonia, nanethyi pyrroiidone, and hazardous waste such as battery metai components. tiotvever, as residue streams, especiaiiy Wastewater streama, rnay he quite voiuminous, reducing the ainount of residues and provide vaiue adding coiriponents from the streams ciassified as waste is desirabie to improve the overaii operation in terms of costs and raw materia! usage of the battery manufacturing faciiity, and aiiotying reuse of the Earths finite resources. Aiso, iocai or nationai reguiations may infiuence if battery production is aiiowabie in view of residues and emissions provided from the processes especiaiiy with regards to emissions to a water recipient. Non-desirahie eiements iike suifates, and sodiuni, may be provided in high ieveis in the battery production, and they negativeiy infiuence the residue process streams as they are expensive to dispose of, and if foiwarded directiy to sewers andlor wastevtfater treatment piants they put a iot of stress on said downstreain processes, and the presence, or prospect of presence, of high amounts of suifates and sodium wouid today prevent approvai of permits forestabiisbing a battery production 'faciiity. Sodium suifate is a probiematic by« product to be handied for battery ntanutacturers. in vievv of the voiumes produced, tbe costs for bandiing sodium suifate may be substantiai, aiso a tack of addressing cbemicai iiandiing may prevent a company from receiving needed permits to continue their production or obtain nevv tiermits for increase in production or buiiding nevv production faciiities.
Today sodium suifate present in residue process streams may be rejected eg, to the Wastewater systern via drains or sewers, or onto iandfiiis or separated from the residue stream and soid as iow-grade chemicais. Residue process streams from a battery production faciiity containing sodium suifate irtainiy originates front the oxidation step of the cathode production. Even if sodium suifate is considered a waste materiai, if a use therefore couid be provided it couid become a vaiued asset as the soditirn suifate can be present in iarge amounts. For a battery manufacturing faciiity handiing the obtained sodium soifate is considered a probiem. Hova/ever, if sodium suifate couid be pot to good use it couid become a vaiuabie-adding product for tbe overaii process.
A probtent with tbe present residue process streams of battery rtianufacturing faciiities is tbat possibie vaiuabie cnemicais are not retrieved or recycied tnerefrom. in reaiity, a iarge amount of cbemicais is aivvayfs discnarged to iandfiii, or disposed of as iow-grade cnernicais, or sent to yvastewater' system.
Today also much focus is put on obtaining environmentally sustainable processes and obtaining as much value adding products or recyclable products out of a process as possible, in order to avoid as much waste and losses as possible.
Thus, there is a need to obtain more efficient processes. There is a demand for processes which reduces the need for putting material on landfills and discharging valuable chemicals to Wastewater system. There is also a need for providing additional value adding products from waste material from battery production or recycling facilities which improves the economy of the total battery production or recycling facilities.
Summary tfi/ith the present process, high vaiue products are obtaihabie and at the same time en environmentaiiy more sustainabie soiution to waste handiing is provided. By providing an added-vaiue product that have a dernand on the market and may be soid the totai economy of a battery production or recycling facility is improved and the recourses of iviother Nature are used with caution. Aiso, the process enabies possibiiity to meet requirements and iegisiations reiated to waste handiing for battery manufacturing. titiith the invention a huge amount of chemioai, nameiy sodium suifate, present in the residue process stream can be used and the negative eitvironmentai impact from a battery residue process stream can be eiimihated. Since a high grade fertiiizer' is obtained by the present invention is it aiso possibie to forward the nutrient chernicais to piants, where they are needed, instead of forwarding them out to a drain or sevver, or onto iandfiiis or separated as iow grade chemicais.
