dc.description.abstract | Production of smart water from produced water is the focus of the thesis. Smart water performance is regulated by the concentration of ions such as Ca2+, Mg2+ and SO42-. Choosing produced water as the source for smart water is a wise step as it reduces produced water discharge making it suitable for pressure support in EOR.
Experimental setup of the project consists of a nanofiltration (NF) membrane coupled with ion exchange for barium removal. NF membrane separation was designated to increase the concentration of Ca2+ and Mg2+ while ion exchange was used for barium removal in order to prevent BaSO4 scaling. These experiments were carried out using synthetic produced water sample from Tor Field.
EM-NF-1812-50 and NANO-BW-4040 NF modules were used. Concentrate from NF was selected as the source of smart water. NF membrane separations were able to increase the concentrations of Ca2+ and Mg2+ by 24 – 85 %. EM-NF-1812-50 gave higher retention while NANO-BW-4040 was more preferable due to its ability in changing the pressure. Ion exchange removed 99 % of barium.
According to the experiments, a combination of separation processes by NF and ion exchange is proposed as a potential solution to increase the quality of produced water as smart water. | nb_NO |
