Sealless Pumps For HF Acid Alkylation Service

Alternative desc

Hydrofluoric Acid (HF) Alkylation is a refining process that mixes hydrocarbons from a fluidized catalytic cracking unit (FCCU) with a HF Acid catalyst, to make high octane gasoline. For decades, pumps and other equipment used in HF Acid Alkylation have been particularly vulnerable to corrosion, because HF Acid by its nature seeks out and attacks imperfections in cast components, leading to pump failures and product leakage.

 

Sundyne HMD has decades of experience in HF Acid Alkylation and has spent more than 7 years working with UOP to demonstrate and validate a proprietary pumping solution that safely & reliably handles HF Acid. The new proprietary solution developed by Sundyne HMD uses a specially adapted material design combined with a new validation method of Non-Destructive Examination (NDE) for the pump casing.  

 

This solution is created exclusively for pumps entering HF Acid service. The unique material design coupled with HMD’s sealless magnetic drive pump technology ensures complete fluid containment and addresses the industry-wide issue of casting failures, offering the highest level of safety and reliability.  

 

HMD Kontro’s specially-engineered and industry-approved offering for HF Acid provides operators with years of uninterrupted operation, while ensuring optimum pump performance, reliability and safety.   

HMD Kontro’s Adapted Material Design for HF Acid:

  • Sealless magnetic drive design with full compliance to API 685 standards.
  • Unique Alloy C22 / C276 material design is specially engineered for use with HF Acid.
  • An extensive testing plan & new methods of NDE validate integrity in HF Acid service.
  • Secondary Containment with secondary casing leak detection for additional protection.
  • Containment Shell Temperature Monitoring & Dry-Run Protection for peace of mind

Unique NDE for Casing Castings: 

In addition to the adapted casting process, HMD Kontro has developed a proprietary NDE process that checks for imperfections in the casting and validates the casting’s integrity for use in HF Acid. This combined with the following additional traditional methods of NDE in line with the API 685 standard verifies the pump suitability for this challenging pump application:

  • Visual Inspection
  • Radiography
  • Dye Penetrant Testing
  • Positive Material Identification

 

Superior, leakproof material design, exclusive to Sundyne HMD Kontro, provides the highest levels of integrity with HF Acid

Site Serviceable Design

Designed for simplicity & site serviceability:

  • No special tools required;
  • Simple to decontaminate;
  • No special motor decontamination needed.

 

Site replaceable Cartridge ensuring minimum disruption in the unlikely event of a breakdown:

  • Cartridge comprises all wetted parts (except main casing) in one assembly;
  • Allows for quick and easy on-site replacement;
  • Cartridge replacement time typically 1 hour or less.
