Technology in the Chemical Process Industry

Understanding the Why

• Then I needed to learn practical process control…..

These guys were my friends.

4

Technology in the Chemical Process Industry

Understanding the Why

• Enter electronic process controls…..

These guys made life easier.

5

Technology in the Chemical Process Industry

Understanding the Why

• Make sure you’re on the right bus with the right protocol…

These guys made life cheaper.

Technology in the Chemical Process Industry

Understanding the Why

• Enter better process stability for quality and productivity:

• Self-tuning controllers

• On-stream analysis and process simulation - APC

• Understanding multiple control loop interaction – MPC

Process technology advances quality.

7

Technology in the Chemical Process Industry

Understanding the Why

• Is this your operations or plant manager?…..

Then process technology went OTT.

8

Technology in the Chemical Process Industry

Understanding the Why

• But is easiness the Why?…..

Process control technology needs to address risk.

9

Technology in the Chemical Process Industry

Understanding the Why

• Enter …Risk Based Process Safety & Event Management

Why not marry RBPS and EM into control systems? Figures from Ullmann’s Encyclopedia of Industrial Chemistry.

10

Technology in the Chemical Process Industry

Understanding the Why

• Enter …The Life Cycle Standard of IEC 61511

and the SIS integrity standard of ISA-84.

This approach begins with identified SIS.

But why stop there?

11

Technology in the Chemical Process Industry

Understanding the Why

• Now let’s get it in front of the operator through:

• Hierarchical alarm management: Flood prevention progressing.

• Live event SME coaching: Now on alarms…other situations.

• LOPA layer status and MOC: Operator disengaged protection.

• Unknown PHA combination flags: Haven’t seen this before!

• Off-line event reconstruction: Show it on screen, not logged.

Now we’re talking!

12

Technology in the Chemical Process Industry

Understanding the Why

• Hierarchical alarm management:

Alarm flooding prevention is now on lower priced systems.

13

Technology in the Chemical Process Industry

Understanding the Why

• Live event Subject Matter Experts coaching:

Now on alarms…why not other situations?

Add QC and efficiency expertise.

14

Technology in the Chemical Process Industry

Understanding the Why

• LOPA layer status and MOC:

Operator disengaged protection. Ah, you just turned

something off that you need.

Manage IPLs and make sure

operators are aware of others.

Protection Layer Probability of FoD

Control Loop 1.0 x 10-1

Human performance (trained,

and under no stress) 1.0 x 10-2 to 1.0 x 10-4

Human performance (under stress) 0.5 to 1.0

Operator response to alarms 1.0 x 10-1

15

Technology in the Chemical Process Industry

Understanding the Why

• Unknown PHA combination flags:

We haven’t seen this situation before!

Simulation HAZOP models exist – why not live?

16

Technology in the Chemical Process Industry

Understanding the Why

• Off-line event reconstruction:

We have a display so show it on screen, not logged.

BPCS should be able to relive the event.

17

Technology in the Chemical Process Industry

Understanding the Why

• Enter …..Interactive Field Devices w/ Procedure Checklists

Let’s make our people smarter with less risk.
