Dear Sirs,

please find below answer to you question:

GLSA is aware of implication between yield and cut point. Cut point 175°C TBP is a part of offers assesment/evaluation.


Kind regards,
Paulina Ohler-Tulińska

Dear Sirs,

please find attached answers to your questions.

Dear Sirs,

please find below answers to your questions:

Firs of all GLSA is very open for meetings with various companies. It is very valuable for us to discuss interesting problems and cases. Sharing of knowledge is very profitable for both sides. For example we used to meet with companies and they present their new approaches with their catalysts, solvents, chemical additives, and new modern technologies. Sometimes there is a need to sign NDA if any data will be sent.
Secondly, due to our internal rules we must treat our bidders equally and in a justice way for all sides. We try to avoid meetings during ongoing purchasing inquires due to internal procedures.

In case 2 we assume that reactor can be filled only with HDS/HDN catalyst without dedicated isomerisation catalyst.
We understand that HDS/HDN catalyst partially also improve cloud point.
So if it is possible to provide CP 12°C, this offer also can be sent.

Kind regards,
Paulina Ohler-Tulińska


Dear Sirs,

the deadline for submitting offers and questions has been extended.

Deadline for submitting questions 13.11.2020
Deadline for submitting offers 30.11.2020

Please find below answer to your questions:

Catalyst loading:
- Can you please provide us with the reactor drawing and the current reactor loading profile ? We cannot provide this data.
Recycle gas :
- Can you please clarify if the provided recycle gas flow rate (125637 Nm3/h maximum) includes or not make up and quench flow rate ? The recycle gas flow rate does not include the make up and quench flow rates. The recycle gas flow rate contains only the discharge stream of the compressor 0520-K1.
- Can you please provide us with the H2 purity for the Recycle gas for summer and winter mode ? We cannot provide this data. Please let us know, what the purity of hydrogen should be?
Winter and summer modes:
- Can you please clarify if the feed quality is the same for winter and summer mode ? The feed quality is the same for winter and summer mode.
- What is the split in term of months of operation between summer and winter modes ? Summer mode is from April to October and winter mode is from November to March.
- Can you please provide the period , which months, corresponding to summer and winter modes? Summer mode is from April to October and winter mode is from November to March.
- At which month of the year are you planning to restart the unit ? The restart of the unit is planned for March/April 2022.
Feed information:
- Can you please confirm that all the streams are Straight run streams except the LCGO which is a coker Gasoil? All streams (LGO, MGO, HGO, LVGO, except the LCGO) are from the distillation units.
Unit information:
- What is the maximum operating temperature ? The design temperature is 454 ˚C, so the maximum operating temperature cannot be higher than this value.
- Can you provide us with process flow diagram for the unit ? We cannot provide this data. We attach a drawing of the reactor.
- What is the maximum pressure drop of the reactor? As in the process data in the attached table No. 3, the maximum pressure drop of the reactor is 900 kPa.

1. Please specify if any feed contaminants are present and their associated values? (e.g. As, Si etc.) Lower detection limit for Si is 0.2 ppm, we can analyse V and Ni in feed and send the results.
- We suppose that data will be also lower than detection limit. We can send the results after analysis is completed.
2. Please state the purity of Treat Gas for the corresponding mol. Weight of 6.43 g/mol and the purity for quench gas?
- Purity of treat gas depends on catalyst activity and cloud point improvement.
3. Would that be possible to provide the breakdown of PNA content in the total feed or would you prefer us to estimate it?
- Average weight contents of aromatic compounds are: mono- 22,2 %, di- 12,4 %, 3+ 1,8 %.
4. Can you please specify the cut point that we should use between Naphtha and Diesel either on a TBP or D86 basis?
- Cut point is – 175°C (TBP).
5. In the ITB you specified a design temperature of 454 deg C which should represent the mechanical limit of the reactor. In order to estimate a reliable cycle length, we would need to use a much lower EOR WABT, so would that be possible to provide either a max outlet temperature or a max WABT at EOR?
- We expect your proposal for WABT and max outlet temperature.
6. An operating pressure interval has been provided between 6,7 and 7,2 MPa. Would you like us to use the average, min or max value?
- 6,7 MPag is normal operating pressure. Please calculate data for this pressure.


Yours faithfully,
Paulina Ohler-Tulińska
