[Case Study] Small Neutralization Device for Sulfuric Acid (pH 3)

I want to neutralize the sulfuric acid! Ultimately, I designed it so that the discharge can be done after checking the pH and opening the electric valve.

We received an inquiry from Company D, a major chemical plant in Niigata Prefecture, stating, "We want to neutralize dilute sulfuric acid. We want it to be as compact as possible for indoor installation." We designed and proposed a small neutralization device that meets the conditions of treating dilute sulfuric acid at a pH of about 3 at room temperature (around 25°C), with a batch liquid volume of 60L and a drainage cycle of once per hour. The discharge will be done by opening an electric valve after confirming the pH, allowing it to flow into the pump provided by the customer. Additionally, regarding the support system that the customer was concerned about, we explained that there is a system in place for emergency response from our Toyama branch, which reassured them. The control panel was also appreciated for its flexible approach, as we shipped only the internal components without the housing for integration into the customer's centralized control panel. 【Case Details】 ■ Delivery: Company D, a major chemical plant in Niigata Prefecture ■ Application: Neutralization of dilute sulfuric acid at a pH of about 3 (batch) ■ Model: Small neutralization device *For more details, please refer to the PDF document or feel free to contact us.
