Abstract—Chlor-alkali is one of the most important processes
in chemical industry. This process produces chlorine and
caustic soda that becomes the main feedstock of daily needs
products. In this study, the process condition on chlorine gas
production by electrolysis plasma is examined. Plasma
electrolysis can increase the chlorine gas production up to 24
times in single compartment reactor and can reach up to 59
times in double compartment reactor compared to electrolysis
process. In reactor with single compartment, high voltage
results high current then cause high-energy consumption. The
highest chlorine gas production is at 0.5 M and 300 V that
results 4.63 mmol within 15 minutes. On the other hand, using
double compartment reactor, current is lower due to its higher
distance between two electrodes that makes the higher
resistance. In this case, the highest chlorine gas production is at
0.5 M NaCl and 700 V that results 11.25 mmol within 15
minutes. The use of ion selective membrane can keep the
movement of charge from one electrode to other. Ion selective
membrane can separate side product of NaOH, but side
reaction of chlorine ion still exists.
