THE CONSENS PROJECT
Intensified continuous processes are a key innovation of the last decade for the production of high quality, high
value and customer-specific products at competitive prices in a sustainable fashion. To realize the potential of
this technology, key steps must be made towards long-term stable, tightly controlled and fully automated
production. The goal of the CONSENS project is to advance the continuous production of high-value products
meeting high quality demands in flexible intensified continuous plants by introducing novel online sensing
equipment and closed loop control of the key product parameters. CONSENS will focus on flexible continuous
plants but the results will be transferable also to large-scale continuous processes. The research and
development is driven by industrial case studies from three different areas, spanning the complete value chain
of chemical production: complex organic synthesis, specialty polymers, and formulation of complex liquids.
Innovative PAT technology will be developed for online concentration measurements (mid-resolution process
NMR), for the online non-invasive measurement of rheological properties of complex fluids, and for continuous
measurements of fouling in tubular reactors. New model-based adaptive control schemes based on innovative
PAT technology will be developed. The project results will be validated in industrial pilot plants for all three
types of processes, including validation in production containers that have been developed in the F3 Factory
project. Further, methods for sensor failure monitoring, control performance monitoring and engineering
support for PAT-based solutions will be developed. The exploitation of the new technologies will be facilitated
by a tool for technology evaluation and economic impact assessment. A Cross sectorial Advisory Board
supports the transfer of PAT technologies and adaptive control to neighboring sectors of the European
processing industry.

1 Executive summary In order to create a first guideline for the CONSENS sensor development process, the corresponding
requirements were specified using questionnaires created by the sensor developers (TNO, BAM) and the
sensor provider (KROHNE). This questionnaire was sent to the case study leaders (INVITE, ARKEMA and P&G) to
get a realistic view of the sensors to be developed at the very beginning of the project. Based on this
questionnaire, the CONSENS case study leaders provided relevant known process information to the sensor
development team.
2 Introduction The future competitiveness of the European chemical industry depends on its ability to deliver high quality and
high value products at competitive prices in a sustainable fashion, and to adapt quickly to changing customer
needs. The use of intensified continuous processes is a promising strategy towards this goal. Compared to
traditional batch processes, intensified continuous production gives access to new and difficult to produce
chemical compounds, leads to better product uniformity and reduces the consumption of raw materials and
energy drastically. The main goal of the CONSENS project is to advance the continuous production of high-
value products that meet high quality demands in flexible intensified continuous plants by introducing novel
online sensing equipment and closed-loop control of the key product parameters.
The research and development is driven by industrial case studies from three different areas, spanning the
complete value chain of chemical production: complex organic synthesis (CASE STUDY 1), specialty polymers
(CASE STUDY 2), and formulation of complex liquids (CASE STUDY 3). Innovative PAT technology will be
developed for online concentration measurements (mid-resolution process NMR), for the online non-invasive
measurement of rheological properties of complex fluids, and for continuous measurements of fouling in
tubular reactors. The following table relates sensor technologies and case studies:

3 The procedure for specifying sensor
requirements After a productive discussion between the sensor developers (TNO, BAM) and the sensor provider (KROHNE)
during the project’s kick-off-meeting it was decided to create questionnaires for asking the case study leaders
(INVITE, ARKEMA and P&G) about their needs. A word-document (see Annex A as an example) was chosen as
the easiest way to get a quick and time-saving response from the users. This document was created by the
sensor developers and the sensor provider and was improved after being filled in by a user (P&G), before it was
sent to all other users.
The detailed method creating the questionnaire can be divided into different phases (see also Figure 1).
Phase A: Principle ideas
A brainstorming by the sensor developers (TNO and BAM) and the sensor provider (KROHNE) was done
during a first meeting to create an idea of what is important to know from the end-users to develop a
functional and useful sensor. It was then decided that KROHNE as an experienced sensor developer would
create the first draft of the requirement questionnaire.
Phase B: Manufacturer perspective
Based on these first ideas the product management and requirement engineering of KROHNE were asked to
expand the questionnaire. The product management of KROHNE has long lasting experience with customer
needs and customized sensor solutions. So it has a very good view to actual products and what is needed in
future applications. The requirement engineer was asked to provide his experience in respect to what is
typically needed in requirement documents.
Phase C: Developer perspective
With these inputs a first draft of a questionnaire was set up and improved in several discussions between
TNO, BAM and KROHNE. The outcome of these discussions was the first generic questionnaire. It provided
the baseline for sensor specific questionnaires, which were developed and further detailed during Phase D.
Phase D: Sensor specific questionnaires
TNO and BAM had updated the questionnaire for FOULING SENSOR, RHEOLOGY SENSOR and
MR-NMR SENSOR regarding the specific questions they needed to be answered for their special sensor
development.
Phase E: Improvement and finalization
After Phase D the creation of the questionnaires was finished from the perspective of sensor developers
and sensor provider. The questionnaire for CASE STUDY 3 was answered by P&G (Phase F) and open points
were discussed during a meeting at P&G in Brussels (Phase G). Any unclear points were eliminated and the
questionnaire for CASE STUDY 3 was finalized during this meeting.
The lessons learned from the review of the RHEOLOGY SENSOR questionnaire (CASE STUDY 3) done by P&G
were integrated into all sensor specific questionnaires and the documents were finalized by KROHNE and
TNO (Phase E).

Phase F + Phase G: Fill-out by end-user + Meeting at end-user to gain common understanding
After sending the remaining documents to the partners for CASE STUDIES 1 and 2 by the work package
leader TNO, all end-users answered their questionnaire. For CASE STUDY 1 (Intensified synthesis of organic
compounds) and CASE STUDY 3 (Continuous production of complex fluids) face to face meetings were held
where all relevant parties were involved. For CASE STUDY 2 (Intensified production of high-viscous
polymers) the questionnaires were filled in under the coordination of the case study leader.
See the table below for the assignment of the questionnaires to the end-user.

4.17 Intrusiveness
What is still acceptable for intrusiveness of the sensor?
Intrusiveness Select an option
absolutely no intrusion into the process, pipe wall cannot be milled down/drilled into
allowed to mill down/drill into pipe wall, but not completely through
allowed to breach seal/mill through pipe wall, as long as sensor is flush mounted in the wall
objects protruding pipe wall allowed
Is it possible to create a separate sensor section (i.e. flanged pipe section)? If so, how will it connect to the rest of the setup? Is the section a straight pipe or is there a curvature?
Separate sensor section Please comment
Is the sensor to be used in-line (i.e. sensor in the main product line), on-line (i.e. sensor in a parallel sampling loop or stop-and-go line), at-line (i.e. sensor measures samples and is not physically connected to process).
In/at/on line Please comment
4.18 Cleanability
What cleaning protocols are used for the process equipment? Is clean in place (CIP) applicable? if so, what is the procedure? What implications does this have on the sensor?

4.19 Maintenance/calibration
What are the protocols with respect to sensor maintenance? Is downtime acceptable for maintenance/calibration? If so, for how long?
Maintenance Please comment
Some models require calibration procedure. Can calibration samples be provided? Is it possible to take (stable/quenched) samples from the process for validation?
Calibration/validation samples Please comment
4.20 Other device requirements
Are there any other requirements?
