Corrosion data of titanium in sodium chloride solution at 2.3% hydrochloric acid concentration
Thread Content
Dear fellow sea enthusiasts, I am seeking data on the corrosion of titanium materials in sodium chloride solution at a 2.3% hydrochloric acid concentration. I hope those experienced in XDJM will be kind enough to share their knowledge The operating conditions are as follows: the material undergoes a heating reaction in a mixture of dichloroethane and saline, with a saline concentration of 18%, a reaction temperature of 120 degrees, and a pressure of approximately 0.55 MPa. The presence of impurities causes acidity in the system; based on the subsequent neutralization data, the hydrochloric acid concentration in the aqueous phase can reach up to 2.3%. It is planned to use titanium materials for this application, and assistance is sought regarding corrosion data for various types of titanium under these conditions. It has been found that titanium materials can be used over a long period of time in a 0.5% hydrochloric acid solution at their boiling point temperature. The batch processing time in the reactor is approximately 15 hours, with the reaction time being around 4 hours. Acid reflux occurs gradually thereafter; it can be assumed that the acid reflux process takes about 2 hours per batch. I would like to know whether equipment made of titanium-lined materials can be used over the long term. What are the precautions to take later?
I’ve already checked; there are no corrosion data available at this temperature for a 2.3% hydrochloric acid concentration. Only the data shown in the diagram is available. I hope someone kind can provide more detailed information
A temperature of 120 degrees reaches our critical point; there is no issue with pressure, and nothing else seems to be wrong either. We can try conducting a hanging-plate experiment.
