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).

8



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.
