Our hydrochloric acid recovery unit operates on the principle of thermal regeneration, where the spent acid is heated to drive off water and concentrate the acid, while impurities are separated as solids or sludge. The PLC ensures precise temperature and pressure control, maximizing efficiency and minimizing downtime. The system includes safety interlocks, emergency shutdown, and automatic fault diagnosis, making it safe and reliable for continuous industrial use.
Benefits to Your Business
Reduce Chemical Costs – Recovered acid can be reused, cutting fresh HCl purchases by up to 95%.
Minimize Waste Disposal – Less spent acid means lower waste treatment and disposal costs.
Environmental Compliance – Meet stringent discharge regulations and reduce your carbon footprint.
Improve Process Consistency – Automatic control ensures stable acid concentration, improving product quality.
Quick Payback – Typical return on investment within 12-18 months, depending on usage.
Global Support – ZLN provides after-sales service, spare parts, and technical support worldwide.

Frequently Asked Questions (FAQ)
Q: How does the hydrochloric acid recovery unit work?
A: The system uses thermal evaporation to separate water and impurities from the spent acid, concentrating the HCl for reuse. PLC controls maintain optimal temperature and pressure for high efficiency.Q: What is the typical recovery rate?
A: Our units typically achieve a recovery rate of 90-95%, depending on the composition of the spent acid and operating conditions. Specific performance can be calculated based on your site data.Q: Is the unit compliant with international standards?
A: Yes, the electrical and control system is designed to comply with IEC standards, and the overall equipment meets common industrial safety requirements. We can also adapt to local standards upon request.Q: What materials are used for construction?
A: The unit is built with corrosion-resistant materials such as PPH (Polypropylene), FRP (Fiberglass Reinforced Plastic), or PVDF, depending on the acid concentration and temperature. Customization is available.Q: What capacity options are available?
A: We offer a wide range of capacities from 100 L/h to over 10,000 L/h. Please provide your spent acid volume and concentration for a tailored solution.Q: How much maintenance is required?
A: The system is designed for low maintenance. Regular checks include cleaning filters, inspecting seals, and calibrating sensors. The PLC provides diagnostic alerts for proactive maintenance.Q: What is the delivery time and shipping terms?
A: Typical lead time is 30-60 days, depending on customization. We ship from Tianjin port, China, under FOB, CIF, or other terms as agreed.Q: Do you provide installation and training?
A: Yes, we offer on-site supervision, commissioning, and training for operators. Remote support is also available via video call.
