Information

To meet environmental regulations, the demand of Hpurification in refinery are growing. From hydro-treating to hydrocracking or hydro-desulfurization, the primary purpose of operations is to convert heavy hydrocarbons to lighter, higher-value fuels or to reduce the sulfur and/or nitrogen within the feedstock. Residual gas from the process contains a significant amount of unused hydrogen.

 

Applications:

• H.P. vent gas with 70-90% H2 purity and 8.0-10.0 MPaG pressure from RDS, H-oil plant.

• L.P. vent gas with 50-70% H2 purity with 2.0 MPaG pressure from HDT, HCR plant

• FCC offgas with 30% H2 purity and 0.5 MPaG pressure

 

Performance:

• H2 recovery: 70-95%

• H2 purities: 95-99.5 mol%

 

Operating characteristic:

• Max. operating temperature: up to 90°C

• Max. operating pressure difference: up to 90 barg

 

Scope of supply:

• Pretreatment

• H2 membrane unit

• PSA as post-treatment (upon request)

• Booster compressor (upon request)

 

Standards:

• Pressure: ASME, BPVC VII Div1

• Electrical: IEC or NEC

• ISO 9001 certified process

• Hazardous (ATEX/Class Div2)
