Temperature Stability of Naphthalene Sulfonic and Naphthalene Disulfonic Acids at Geothermal Conditions


An experiment has been performed to investigate the stability of the four naphthalene disulfonic acids (2,6-NDS, 2,7-NDS, 1,5NDS, 1,6-NDS) and two naphthalene sulfonic acids (1-NSA, 2-NSA) using a hydrothermal flow simulator. The experimental fluid was pH-modified, low pressure separator brine from the Nga Awa Purua power station at the Rotokawa geothermal… (More)
