Presentation Outline

• NeSSI Objectives• NeSSI Implementation Strategy (2004)• NeSSI Evaluation Objectives (2004)• Dow Installation Activities• Testing Activities in Dow• The Design & Integration Dilemma

3

NeSSI Objectives• Facilitate the acceptance/implementation of...

– modular, miniature & smart sample system technology– based on ANSI/ISA SP76 standard substrate

• Promote the concept of...– field-mounted (By-Line) smart analytical systems

• Lay the groundwork for...Pipe to Pixel™ architecture (GenII)– open connectivity architecture for intrinsically safe

transducer communications (e.g. CAN, ProfiBus, FF, etc.)

– industry standard communication protocols (e.g. Ethernet, OPC, etc.)

• Provide a technology bridge to the process for...– “sensor/lab-on-a-chip” micro-analytical devices (Gen

III)

Dow Installation Strategy (2004)

• Deploy SP76 substrates and components from allsuppliers in various businesses with NeSSI-net team…– chlor-vinyl, hydrocarbon, energy, solvents,

glycol/ethylene oxide, styrenics, environment, polyolefins

• Target applications: CEMS, flare monitoring, multi-stream hydrocarbon measurements, air monitoring, lethal service, on substrate moisture and oxygen measurements– 7 applications field operated - 9 in progress

Dow/NeSSI Evaluation Objectives (2004)

• Explore a “Drop Ship” Integration Concept• Fill gaps in modular product offerings by ordering

emerging products• Get a deeper understanding of cost issues,

barriers & design issues• Keep the door open near term for all suppliers• Conduct a comprehensive testing program.• Work with strategic partners to drive prototype

development of smart sensors and actuators as outlined in the CPAC NeSSI Gen II specification

Challenge: Replace a Complex & Critical Conventional System Using Modular Technology

Hydrocarbon Distribution Service

8

Modular Solution…

• Complex System - 3 streams, 2 GC’s, 2 cals.

• New Features– Balanced orifice stream

switching– Diaphragm Valves– No DB&B Valving

• 0.66 cost of conventional system

• 1/5th size of conventional• 6 weeks from order to

operation• delighted customer

Dow Detailed Evaluation• The NeSSI-box Experimental Platform:

– Installed in Hydrocarbon Plant

15

NeSSI-box Upper Compartment

• Monitor & Control

• Power Supplies

• Programmable Logic Controller (PLC)

• Graphic User Interface

• Wireless Transmitter

• Class I Div.2 Gp C,D

• First Sensor Actuator Manager (SAMjr)

16

NeSSI-box Lower Compartment

• Houses substrate under test

• Electrical interface to a PLC

•Declassified to General Purpose• X-Purged & Haz. Gas Detector• allows use of non-certified equip.

• Temperature Controlled

Dow Test Objectives

• Field Test & conduct team post-evaluation using 4 different systems for approximately 4 weeks (reuse many of the surface mounted components)

Learning's from the NeSSI-box:4-20 mA not viable for Gen II/III

• labor intensive wiring• space hungry• expensive and difficult to wire

for hazardous electrical areas• need for a Sensor Actuator

Manager to unload I/O• need for a serial bus

Gen II Proof of Concept Apparatus (POCA) -Dow, EMCC, UOP, Honeywell

Features- serial connectivity - PC controlled – smart features- simple plug and play M8 connector

Benefits - predict failures before they happen- remote operation in hostile locations- decrease maintenance- increase confidence

GET SMART!

ARC Advisory Group suggests that 40%maintenance savings can be achieved by

automation

25

Tighter Integration In Progress

• Recommended Improvements– Lower cost interconnections– Substrate panel fits

enclosure mtg. system– Modular entries for tubing

and heat tracing– More elegant integration of

heating system into the enclosure

– Enclosure, heating products & tagging included in the software configuration package

26

An Ideal Gen I System• No tube bending or skilled assembly• A modular enclosure system• Low cost (Div 1) F & P switch/transmitter which operates

either vertical & horizontal (+/- 5%)• minimal non-modular components• Highly flexible in both x and y directions• Ease of End User reconfiguration• Ease of design & assembly• Low part count & light weight• Better visibility of flow paths by means of indicating

sensors, colour coding, valve position indicators

27

Integration Dilemma

• With a software configurator who designs?– end user, analyzer manufacturer, sample system

manufacturer or system integrator• Assuming unskilled labour to build who

assembles and tests?– end user, analyzer manufacturer, sample system

manufacturer or system integrator

28

Where are we today?• Gen I products widely available

– approximately 80 components• Increased adoption and acceptance of

NeSSI™ as an industrial platform• Early Gen II “smart” concept

demonstrated– DOE consortium will drive a standard

• Gen I Costs – slowly coming into line– typically x1.2 conventional

• Need more work with the drop-ship concept and integration into an enclosure

• What is better? A Lego® block or Tinker Toy approach?
