CG Thermal - Sulfuric Acid Systems for Industrial Applications
CG Thermal provides expertise in developing sulfuric acid systems for processing Sulfuric acid (H2S04). Sulfuric acid is the most commonly produced and highly critical industrial chemical worldwide, useful in producing hundreds of other essential compounds. Moreover, production of many important acids relies chiefly on sulfuric acid, and it is also used as a catalyst in the alkylation process of high-octane gasoline production in petroleum refining. In addition to being a good catalyst, it is highly reactive with water, and therefore commonly used in dehydration processes.
Industries & Uses
- Production of phosphoric acid
- Fertilizer production
- Production of esters
- Nitration of toluene and aromatics
- Dehydration processes
- Metal manufacturing, including copper and zinc
- Cleaning of steel
Its popularity and utility continue to soar worldwide, growing over 3% a year, partly fueled by growing demand in the Asia-Pacific region. Because sulfuric acid is used in manufacturing important products such as phones, electronics, paper, specialty chemicals, personal care products, and fertilizer, it increasingly influences economies worldwide. As heat and mass transfer experts, the CG Thermal systems group has been instrumental in implementing sulfuric acid systems used in this popular and growing industry.
A properly designed dilution system, with attention to materials of construction and control, is critical to obtaining the desired end result. First, the concentrated acid is introduced to the feed water in a mixing tee. As a result, substantial heat is generated in the process, therefore the ratios and rate of dilution must be carefully controlled and monitored.
CG Thermal is your partner in the process design. We provide skid mounted sulfuric acid dilution systems custom designed for your process requirements. If you are not looking for a skid mounted system, we can provide a menu of engineering services to sync with your in house capabilities, or simply the components per your specifications.

Although our Impervite graphite excels in harsh and corrosive process streams up to certain concentrations and temperature ratings, our Umax Advanced Ceramic heat exchangers are universally corrosion and erosion resistant, making them the optimal choice for sulfuric acid dilution systems. The Umax tube will not corrode at any concentration and boasts a lifetime guarantee. Since it is 50% harder than tungsten carbide, the Umax tube can be used at higher velocities without concern of erosion. The ability to operate at higher velocities coupled with it’s high thermal conductivity, make it the most thermally efficient choice. Ultimately, the innovative tubesheet design offers superior serviceability, allowing for easy access to all tubes for cleaning and in-house repair.
We Can Help
We will include a recirculating loop to ensure thorough mixing and reduce the temperature seen by system components. If your plant would benefit from redundancy, we will design with (2) heat exchangers in series.
The system can be supplied with completely customized instrument and controls for receiving temperature, flow, pressure, and concentration inputs and generating outputs to control valves and pumps to maintain the desired outlet temperature and concentration. An HDMI can either be skid or remotely mounted. We can terminate at the PLC compatible with your Digital Control System (DCS).
Ultimately, we can provide a proposal with as little information as the batch size (tons/day or lbs/hr), inlet concentration and the desired diluted concentration. Each system can be customized to meet your layout, material preferences, and specific needs.
Turnkey System Includes:
- Custom design to achieve your specified criteria ( dilution rate, concentration and temperature)
- A quoted option includes a glycol chiller to use as cooling water. This will reduce operating costs significantly and reduce size of HX needed.
- Conductivity sensors are located after the heat exchanger with flow control valves on acid feed will control product acid concentration.
- Flow sensors on the acid feed will achieve consistent product and production rate
- Level sensors and switches can be provided on tanks to prevent overfilling or running pumps dry
- Flow sensor and switches are used on the cooling water to ensure safe and sufficient flow.
- Temperature sensors on acid streams will ensure safe temperatures.
- Instrument display, PID controllers, and pump controls are located for easy access.
