Abstract
A process for reducing the salinity of salt containing material (SCM) includes introducing the SCM into a wash system configured to sequentially wash the SCM with water having decreasing salinity levels across a plurality of mixing tanks arranged in series; introducing feed water into the wash system in a countercurrent flow relative to the SCM; discharging washed SCM from the wash system, the washed SCM having a lower salinity compared to the SCM that is initially introduced into the wash system; and discharging brine from the wash system, the brine being generated in a mixing tank that initially receives the SCM into the wash system.
Claims9
A method of reducing salinity of salt-containing material (SCM) generated during production of hydrocarbons from a reservoir, the method comprising:
- introducing the SCM into a wash system comprising at least one mixing tank;
- introducing feed water into the wash system in a countercurrent flow relative to the SCM;
- mixing the SCM and the feed water in the at least one mixing tank to produce brine and a washed SCM;
- discharging washed SCM from the wash system, the washed SCM having a lower salinity compared to the SCM that is initially introduced into the wash system;
- and
- discharging brine from the wash system, the brine being generated from the feed water and having a higher salinity compared to the feed water.
