the purpose of this consultation is to:

The award of a supply and services contract for the acquisition of a crystallizer and its two associated probes. IFP Energies nouvelles is launching a consultation in order to collect bids from qualified professionals with the professional, technical and financial capacity to ensure the execution and perfect completion of the contract and, more generally, to provide advice and expertise to this end.

R&I requirements therefore relate to different aspects of the installation, i.e. to the components

Main:

For spectrometer and infrared probe:

- The spectrometer must be able to be fibered and connected to probes in order to be able to perform in situ characterizations (all necessary accessories must be included).

- The material must be adaptable according to the type of matrix (more or less absorbent).

- The hardware must be automated, and allow online tracking, processing, and serial data extraction (PC control).

- The equipment must be of robust design and without routine maintenance.

- The probe will also have to withstand the medium in which it will be immersed (basic for the most part: useful pH = 0-14), in temperature and pressure as defined above.

- The wavelength range measured by the probe must also cover those of interest for the study of environments, i.e. between 600 and 1900 cm-1 typically.

- The probe must be able to adapt to the set-up and the processing software provided must be easy to use and use, and allow the launch of spectral acquisition in a few clicks. Serial data acquisition should be possible (reaction monitoring over time). The output format of spectral files should be compatible with Excel (e.g. *.txt, *.csv, *.xls), as well as Matlab or executables created via Matlab. Compatibility with files in *.spc format is desired (viewing old spectra and exporting).

For the microscopic probe:

- The apparatus must be able to be fiber-bound and connected to probes in order to be able to carry out in situ characterizations (all the necessary accessories must be included).

- The hardware must be automated, and allow online tracking, processing, and serial data extraction (PC control).

- The equipment must be of robust design and without routine maintenance.

- The probe will also have to withstand the medium in which it will be immersed (basic for the most part: useful pH = 0-14), in temperature and pressure as defined above.

- The typical particle size range of the objects that can be analysed should be between 1 and 500 μm.

- The probe must be able to adapt to the set-up and the processing software provided must be easy to use and to use, and allow the acquisition of the particle size distribution of objects in a few clicks (PC control).

Serial data acquisition should be possible (reaction monitoring and solid formation over time). The output format of spectral files should be compatible with excel (e.g. *.txt, *.csv, *.xls), as well as Matlab or executables created via Matlab. Compatibility with files in *.spc format is desired (viewing old spectra and exporting).

- The analyzer must be able to give accurate data regardless of the shape of the objects.

For your information, the microscopic probe will be placed in a set comprising:

- A 0.5L glass stirred reactor used between 10-120°C under a pressure of 1-3.5 bar imperative, ideally between 10 and 150°C and pressure of 0.5-4bar, into which several elements will be introduced including the microscopic probe.

- A gas phase analyzer at the reactor outlet.

- A spectrometer and the infrared probe connected to probes in order to be able to carry out in situ characterizations. Finally, to have an overall view, the assembly will have to be placed under fume cupboard for safety reasons.

For the reactor and the management of the surrounding fluids:

- Have a large 0.5L glass stirred reactor allowing the study of precipitation supporting temperature (10-130°C) but also and above all pressure (1-4bar), in order to be able to work on a range representative of the CO2 capture conditions of interest.

- The reactor will have a minimum of 7 taps on the lid and a vessel bottom drain valve if possible. The taps will allow the 2 probes, one IR and the other microscopy, a central tapping for controlled agitation of the medium, peripheral taps for temperature measurement, pH reading, gas inlet and outlet.

- The gases will be able to pass through the various components of the assembly, i.e. the reactor, the condenser and the gas analyzer at the outlet.

- Enable the precise and controlled introduction, even in deferred mode (PC control), of the mixture of reaction gases such as CO2, air and nitrogen typically over a wide range of flow rates typically to control gas residence times, even close to one second. The volume proportions of CO2 must be able to be

analysed in the gas phase from 100% vol. to 0.01% vol. to reach the ppm scale. For example, two CO2 inlets, one pure and the other diluted, can be present in order to maintain flow meters with achievable accuracy ranges.

- The in situ pressure of the reactor will be controlled, also on a delayed basis, by a spiller at the reactor outlet after a condenser (order: reactor, condenser, spiller). The outlet gases will therefore pass through a quantitative analyzer before exiting at the vent.

- The variables recorded by the PLC will be stored locally and reported through a historization system for a detailed exploitation of the results.

As an indication, the Separation Department will also be equipped with the following analysers, the tapping of which must be provided:

- A gas phase analyzer at the reactor outlet.

- A spectrometer and the infrared probe fibered and connected to probes in order to be able to carry out in situ characterizations (all the necessary accessories must be included).

- A microscopic probe

Finally, to have an overall view, the assembly will have to be placed under fume cupboard for safety reasons.

R&I requirements therefore relate to different aspects of the installation, i.e. to the components

Main:

For the gas phase analyzer at the reactor outlet:

- The preferred analyte will be the CO2 gas phase, the measurement will be in-line (pc control) with low acquisition times of the order of a few seconds.

- The measured CO2 concentrations can typically vary from 0 to 100% vol. of the flux. A variation of +/- 0.5 or preferred 0.1 %vol. would be desirable. The specificity of this type of analyzer compared to what is commonly encountered in the department is the small number of gases analyzed quantitatively and the need for simplicity of installation and transport. The objective is also to be able to benefit from an online analyzer whose data can be monitored and recorded locally and easily relocated for use on a bench for example (small footprint).

For your information, the spectrometer and the infrared probe:

- A microscopic probe to observe the morphology, such as the beginnings of nucleation of the solid part.
