Sulphuric Acid Plant


The State-of-the-Art DCDA Sulphuric Acid Plant: An Epitome of Environmental Friendliness

The sulphuric acid plant operating with the DCDA (Double Conversion Double Absorption) process stands out as the epitome of sophistication and technological advancement in the global industrial landscape. With its highly precise online monitoring facilities and a modernised control room, this cutting-edge facility sets new standards for efficiency, safety, and environmental consciousness.

Key Points

Environmental-Friendly Design

The plant’s commitment to environmental protection is evident in every aspect of its design and operation. Through the selection of high-efficiency process parameters, the plant maximises resource utilisation while minimising waste generation. Moreover, the integration of an online gas monitoring and alkali scrubbing system ensures that emissions are meticulously controlled, reducing the release of harmful substances into the atmosphere.


Safety Measures

Ensuring the safety of both personnel and the environment is a top priority for the plant. To this end, high-efficiency candle filters and demister pads are employed to eliminate any potential particulate matter that could escape from the process. These advanced filtration techniques not only enhance safety but also improve overall plant performance.


DCDA Process: A Technological Marvel

The Double Conversion Double Absorption (DCDA) process is the cornerstone of the plant’s success. This sophisticated technique enables the conversion of sulphur dioxide (SO2) into sulphur trioxide (SO3) with remarkable efficiency. The subsequent absorption of SO3 in a dual-absorption tower yields high-purity sulphuric acid, setting a new industry standard.


Online Monitoring Facilities

The plant’s online monitoring facilities represent a ground-breaking leap forward in process control and optimisation. Equipped with state-of-the-art sensors and analytical tools, the system provides real-time data to operators, enabling them to make informed decisions promptly. This not only enhances the plant’s productivity but also reduces the risk of unplanned downtime.


Modernised Control Room

A modernised control room serves as the operational nerve center of the plant. Featuring advanced control systems and human-machine interfaces, it empowers operators to oversee the entire process seamlessly. The ergonomic design of the control room enhances decision-making efficiency and contributes to a safer and more productive work environment.



The construction and commissioning of the plant were carried out by the esteemed Ms. Dharamjee Morarjee Construction Company (DMCC), known for its pioneering designs. Additionally, the plant demonstrates further innovation with the establishment and commissioning of a one-megawatt power plant that efficiently utilises waste steam generated during the process.

Among the notable attributes of this plant are its impressive acid storage capacity of 4000 MT and sulphur storage capacity of 10,000 MT, both conveniently situated within the Acid Plant area. These features enhance the plant’s efficiency and underscore its significance in the industry.



The DCDA sulphuric acid plant is a testament to the incredible progress made in industrial processes. Through its advanced DCDA technique, high-tech online monitoring facilities, and a modernised control room, it remains at the forefront of industrial sophistication. Moreover, its unwavering dedication to environmental friendliness sets a shining example for other facilities worldwide. As the industry continues to evolve, this plant serves as a symbol of harmonious coexistence between technology, productivity, and environmental stewardship.
