Welcome members

Project objective

To give engineers ionic modeling capabilities for HF Alkylation


  • To facilitate development of accurate IOWs

  • To minimize corrosion of phase-change-driven water rich HF

  • For process optimization

  • For safer operation of HF Alkylation units 

Current actions - July  2019


  • Members: please send Pat & Andy any description of general, structural, qualitative or quantitative characterization of the ASOs you are seeing in your HF Alkylation process. If you are working with multiple units or see different types of ASOs, please send us the multiple information. We will be developing ASO 'types' to include in your simulations and so knowing as much as possible about your ASOs now is a good preparation!

  • Members: please start data collection based on the worksheet 19HF-001

  • Modelers: are waiting for the ASO information from members to target further ASO searches

  • Modelers: are working on the HF-HC parameters for the known hydrocarbons


Project meetings 


We will schedule a monthly update meeting via web on the 3rd Thursday of the month, beginning in September 2019

​Next meeting


19 September 2019 at 10am Eastern USA time

Project objectives:

  • To give engineers ionic modeling capabilities for HF Alkylation

  • To facilitate development of accurate IOWs

  • To minimize corrosion of phase-change-driven water rich HF

  • To provide tools for process optimization

  • To provide tools for safer operation of HF Alkylation units 

Current actions - Last update 28 May 2020


  • During the meeting on May 21, JIP members voted to add some additional hydrocarbons to better characterize the alkylate stream for improving the Flowsheet model rather than to add heavier ASOs. A survey will be sent following the discussion at the meeting to collect the Top 4 hydrocarbons to add to the databank. Finally, as a consequence of this decision, we will extend the JIP another month, with our conclusion coming at the end of July 2020.

  • ASO parameters have been updated - the OLI TPM team have updated the parameters based on preliminary JIP member feedback in order to better match experience (literature has been exhausted). New databank is available below as 20HF-002-2. Updated installation guide available as 20HF-003-1. (Note this databank does not include the additional components to better model alkylate. An estimate for completion of this task will be provided after the survey is complete).  

  • Modelers: We will be setting up office hours to support your modeling efforts following the OLI Flowsheet training on May 28. 

  • Members:  Additional data beyond what is found in the initial data collection spreadsheet (19HF-001 below) will be required to complete the Flowsheet model that was demonstrated in the April 16 and May 21 meeting. The Flowsheet model will be required in order to determine the amount of entrained rich HF (and amount of water) in the column feed, which is in turn critical in establishing conditions which can cause corrosion. Refer to email sent 16 April after the monthly JIP meeting.  

  • Modelers: 4 new files:

1.   OLI Flowsheet & Studio files used in the May 28 training (zip file): 20HF-017

2.   Recording of OLI Flowsheet training May 28: 20HF-018

3.   Guide for OLI Flowsheet template (Draft): 20HF-015-1

4.   Follow the Water and HF guide: 20HF-016

Project meetings 


To be scheduled: OLI will host office hours following the training session on the use of OLI Flowsheet on May 28. Details to come.

June 18, 2020 Our next JIP meeting will be held at 10 AM EDT on June 18.  Agenda will be sent prior to meeting.
