C) Water? Hmm, I don't think adding more water to the process is going to solve the HCl problem. Maybe the person who wrote this question was a little thirsty.

I'm not sure, but I think it could also be C) Water. Water injection is commonly used in oil and gas processes.

B) Nitrogen? Really? Nitrogen injection? That's like trying to put out a fire with gasoline!

I think the answer is D) Caustic. Injecting caustic downstream of the desalter helps neutralize the HCl in the overhead stream.
