Gas Purification

Gas purification is one of the most critical stages in many industrial processes, directly affecting the quality of the final product, downstream equipment efficiency, operational safety, and process stability. Process gases typically contain impurities such as moisture, carbon dioxide, oxygen, nitrogen, heavy hydrocarbons, sulfur compounds, and suspended particles, which must be completely or selectively removed depending on the final application.

At Atieh Pardazan Sharif Holding, gas purification systems are designed with precise engineering tailored to real process conditions. These units meet the needs of the oil and gas industries, refineries, petrochemical complexes, chemical industries, power plants, steel production, and advanced process units, enabling access to industrial gases with stable and reliable purity.

Process Engineering and Purification Technology Selection

Selecting the appropriate technology for gas purification depends on factors such as the type of gas, impurity composition, operating pressure and temperature, flow rate, and required purity level. At Atieh Pardazan Sharif, unit design is based on detailed process analysis and technical-economic comparison of different technologies to identify the optimal solution for each project.

Depending on project requirements, technologies such as Pressure Swing Adsorption (PSA), membrane separation systems, chemical absorption units, and hybrid systems are employed. This flexibility in technology selection ensures high efficiency, optimized energy consumption, and stable performance of the final system.

Gas Purification Using PSA Technology

PSA technology is one of the most widely used methods for purifying gases such as hydrogen, methane, nitrogen, oxygen, and other special process gases. In PSA systems, specialized adsorbent beds undergo precise pressure cycles to selectively remove impurities, producing a consistent quality purified gas at the outlet.

PSA systems are designed to provide precise purity control, minimal pressure drop, and reduced loss of valuable gas. The modular structure of these units allows for capacity expansion, adsorbent bed replacement, and maintenance operations without a complete process shutdown.

Industrial and Process Gas Purification

Gas purification units at Atieh Pardazan Sharif are designed for a wide range of gases, including methane for fuel and process applications, hydrogen for refining and chemical industries, nitrogen for inerting applications, and oxygen for industrial and medical processes. The required purity level for each gas is defined based on the project, and the control system is designed to maintain this purity under all operating conditions.

These units can be implemented as standalone packages or as part of a larger process facility and can be seamlessly integrated with existing site infrastructure.

Control and Safety Systems in Gas Purification Units

Given that many industrial gases are flammable, asphyxiating, or under high pressure, safety is a core aspect of unit design. Gas purification systems incorporate integrated monitoring of pressure, temperature, flow rate, and online gas analysis.

PLC- and SCADA-based control systems enable real-time process control, operational data logging, and emergency condition management, enhancing reliability and operational safety.

Construction, Testing, and Commissioning of Gas Purification Units

All gas purification units are fabricated in specialized workshops at Atieh Pardazan Sharif Holding under the supervision of process engineers and quality control teams. Before delivery, equipment undergoes pressure, leakage, performance, and control system tests (FAT) to verify proper operation.

Upon installation at the site, commissioning, final acceptance tests (SAT), and operator training are conducted to ensure the unit enters service with maximum efficiency and safety.
