Balaji Speciality Chemicals Limited (BSCL), a subsidiary of Balaji Amines Limited, has selected Hydrogen Gentech P. Limited (HGPL) to design, engineer, manufacture, supply, and commission its Hydrogen Purification Unit (HPU). The Unit will generate high-purity hydrogen using the methanol cracking process.
To produce high-purity hydrogen, the H2 Purification process technology involves a process study of the composition of mixed gas received at the outlet of the methanol cracking reactor.
This study determines the suitable adsorbents required to remove each impurity via adsorption-based removal and achieve the desired purity level of the hydrogen product.
The PSA-based hydrogen purification system will have five towers working cyclically in different phases of H2 generation and tower regeneration stages. Each of the five towers will cyclically work in high purity H2 generation mode while the other four towers operate in different stages of pressurization, depressurization, equalization, and regeneration modes. This design allows for continuous generation of pure H2.
The adsorber tower for the PSA-based hydrogen purification system will consist of a customized multi-layered, molecular sieve-based adsorption bed system based on the type and quantum of impurities present in the mixed gas streams. The design will ensure that high purity H2 is generated while minimizing the loss of any H2 during the adsorption process.
HGPL’s scope of work includes detailed engineering, procurement, manufacturing, supply, erection supervision and commissioning, Performance Guarantee Test Run (PGTR), and training. The PGTR will ensure that the unit performs as per the specified parameters and guarantees the performance of the system.
The HPU will be fully automatic, with a control system that includes all safety measures. The PSA-based hydrogen purification technology is a popular route to establish small and medium capacity H2 generation plants, making HGPL a fast-emerging key technology player in India in the field of Hydrogen generation and Purification systems using the Methanol cracking process.
Hydrogen Gentech Private Limited (HGPL) is an international technology-based Hydrogen Generation plants EPC Company, manufacturer, and supplier based in India. The company has a clear focus on Green Hydrogen Generation, Purification, Recovery & Storage solutions & its applications in industry, renewable energy, fuel, and mobility sectors.
