Hydrogen Production & Purification

Hydrogen gas, as one of the most important industrial and strategic gases, plays a key role in oil and gas, refineries, petrochemical, chemical industries, steel, power plants, and renewable energy processes. The growing demand for high-purity, stable, and safe hydrogen has made the design and implementation of hydrogen production and purification units a fully specialized and engineering-driven field.

At Atieh Pardazan Sharif Holding, hydrogen production and purification units are designed and executed under an EPC approach, based on detailed process analysis, operational conditions, and project safety requirements. The goal of these units is to achieve maximum production efficiency, the highest purity levels, and minimum energy consumption while ensuring operational safety.

Hydrogen Production Process Engineering

The design of hydrogen production units depends on the source of hydrogen, required capacity, and final gas application. Hydrogen can be produced from process by-product streams, synthesis gas, hydrocarbon reforming, or recovered from industrial units. The production method for each project is determined through a thorough assessment of process economics, feedstock availability, environmental regulations, and operational sustainability.

In the engineering phase, detailed documentation such as PFDs, P&IDs, process simulations, mass and energy balances, thermodynamic calculations, and control system design is prepared. This phase is crucial to ensuring stable unit performance under various operating conditions.

Hydrogen Purification and Achieving Different Grades

After production, hydrogen purification is one of the most critical process stages. Raw hydrogen usually contains impurities such as carbon dioxide (CO₂), carbon monoxide (CO), methane (CH₄), nitrogen (N₂), water vapor, and sulfur compounds, which must be completely or selectively removed depending on the final application.

In units designed by Atieh Pardazan Sharif Holding, hydrogen purification is performed using advanced Pressure Swing Adsorption (PSA) technology, membrane systems, or a combination of these methods. These systems allow achieving high-purity hydrogen up to industrial and ultra-high purity grades while ensuring stable performance and optimized energy consumption.

PSA Systems in Hydrogen Purification

PSA technology is one of the most common and reliable methods for hydrogen purification. In these systems, specialized adsorbent beds undergo precise pressure cycles to selectively remove impurities, producing hydrogen with stable purity at the outlet.

PSA system design ensures precise purity control, minimal hydrogen losses, and extended adsorbent bed life. The modular structure of these systems also allows capacity expansion and future unit development without major modifications.

Process Safety and Control in Hydrogen Units

Due to hydrogen’s high flammability and sensitivity, safety is a core aspect of unit design. Hydrogen production and purification units integrate advanced control systems, pressure protection equipment, leak detection, and emergency shutdown systems.

PLC- and SCADA-based control systems provide real-time monitoring of pressure, temperature, flow rate, and gas purity, preventing unsafe conditions. This level of control significantly enhances operational reliability and safety.

Construction, Testing, and Commissioning of Hydrogen Units

All hydrogen production and purification units are fabricated in specialized workshops of Atieh Pardazan Sharif Holding under the supervision of process engineers and quality control teams. Before site delivery, equipment undergoes pressure tests, leak tests, functional tests, and control system verification (FAT) to confirm proper operation.

After site installation, commissioning, final acceptance tests (SAT), and operator training are performed to ensure the unit enters operation with maximum efficiency and safety.
