HF Valves (Alkylation) – UOP certified

HF Alkylation Valves

The Alkylation units is a conversion processes used in petroleum refineries. It is used to convert isobutane and low-molecular-weight alkenes (primarily a mixture of propene and butene) into alkylate, a high octane gasoline component. This process occurs in the presence of a strong acting acid such as sulfuric acid or hydrofluoric acid (HF) as catalyst. Depending on the acid used, the unit takes the name of SAAU (Sulphuric Acid Alkylation Unit) or HFAU (Hydrofluoric Acid Alkylation Unit). In this process, the below shown valves are suitable for use in this application.

  • Gate valves
  • Plug valves
  • Globe valves
  • Swing check valves
  • Piston check valves

The material(s) of these valves will be determined to which pipe class they will fall under and to which HF concentration they are suitable to use.

Pipe : Class :  Body : material : Trim : Class : HF concentration

  • HF1; HF10  Monel  Monel  300, 600, 800  80 to 98
  • HF2; HF20  Carbon steel  Monel  300, 600, 800  0,4 to 98
  • HF4; HF40   Carbon steel  Monel  150  1ppm to 50ppm
