Spirit of S88
• S88 isn’t just a standard for software, equipment, or proceedures
• It’s a way of thinking, a design philosophy• Understanding S88 will help you better design
your processes and manufacture your products
S88 works with ALL levelsof automation
S-88 Expectations
• Decreased Batch Cycle Times• Increased Cell Productivity• Reduced Product to Market Commercialization Time
– IE, New Recipe Creation• Configurable/Changeable Recipes• Consistent Product Quality• Standardized Vocabulary• New ways to SPC the process
– Duration of Operations and phases

212 Building (Cell)Pulp/Paper Coatings• 5 types of Units -
– Equilibration Kettles– Feed Tank– Volatiles Stripping
• 60 recipes• Average Batch Time ~ 20 Hours• More than 2,100 batches / year / cell
@ 90% OEE
OEE – Overall Equipment Effectiveness
• Availability = Operating Time / Planned Production Time• Performance = (Parts Produced * Ideal Cycle Time) / Available
TimeIdeal Cycle Time is the minimum cycle time that your process can be expected to achieve in optimal circumstances. It is sometimes called Design Cycle Time, Theoretical Cycle Time or Nameplate Capacity.
• Quality = Good Pieces / Total Pieces
• OEE = Availability x Performance x Quality• OEE Factors in downtime (scheduled and
unscheduled), bad quality, and of not running at design rates

A Simplier Breakdown
• Original Code was 186 sequential steps,
with 6 actions per step• New Code is 9 Equipment modules and 39 total phases
– Jacket Temperature– Agitation– External Heat Exchanger– Vessel Pressure Blanketing / Vacuum– Raw Material Feeds– Catalyst Feeds– Atmosphere Inerting– Bottoms Liquid Recirculation / Filtration– Timing and Messaging

How did we get there?
• Okay, so 22% reduction in average batch cycle time! Wow!– 2 ingredients were loaded in series 2 ingredients are loaded in parallel– Agitation was started after both raw materials were loaded Agitation starts as soon the bottom impeller is submerged– Mix time used to be 1 hour to ensure adequate mixing Mix time was left at 1 hour…
but ingredients are loaded at a constant ratio to each other– Heating began only when all ingredients were loaded and mix time
completed Heating begins just after kettle loading is 1/10 complete
19
But I could do all that without S-88!
• Yes, you could, if you knew it all in the beginning
and, if things didn’t change…
• But…
Speed and agility are keys to new market successes
• S-88 delivers value, because your equipment can be used to do whatever your equipment can do, which is more than it was meant to do.

Typical Dow Corning Benefits
• On average, a 15-25% decrease in batch cycle times (dependent on product mix)
• Segmented and understandable chunks of code• Graphically organized procedures• Improved communications between control objectives,
operations, logistics, and maintenance• New Product (recipe) creation has complete flexibility
– Within the constraints of the equipment, not simply what you originally intended to do with it
• Employees without specific process control knowledge and training can make recipe modifications and optimizations
Wyeth-Ayerst LederleRecipe Case Study
• The presentation by Greyssi Campos, control systems engineer at Wyeth-Ayerst Lederle, showed how S88 was used to improve process batch control and plant operations at Wyeth's pharmaceutical plant in Carolina, Puerto Rico.
• This plant produces various antibioticsusing a variety of different recipes.
ControlGlobal.com, 10/25/2006http://www.controlglobal.com/industrynews/2006/131.html
Greyssi Campos
• “Prior to our S88 implementation, it was very difficult to modify existing recipes or create new recipes.”
• “Each recipe change had to be validated, and no recipe could be modified without the involvement of control system engineers. This was very time consuming and unwieldy.”
– S88 fixed this problem at Wyeth by separating plant operations and process control into two categories.
Wyeth-Ayerst LederleCase Study, Cont. ControlGlobal.com, 10/25/2006
http://www.controlglobal.com/industrynews/2006/131.html
• “Before we implemented S88, each recipe change required new code, new graphics, and validation of both in addition to validation of the recipe.”
• “S88 has saved us a tremendous amount of time and money by eliminating code and graphic validation when recipes are changed.”
When a new recipe is created or an existing recipe is modified, Wyeth now only needs to validate the recipe itself because all of the unit operations that were combined and linked to create the recipe were previously validated.
Wyeth-Ayerst LederleCase Study, Cont. ControlGlobal.com, 10/25/2006
http://www.controlglobal.com/industrynews/2006/131.html
Recipe Creation
• Graphically Driven – Drag and Drop• Doesn’t require controls experience to create or modify recipes• Users choice for parallel or series branching
– At all levels of the recipe:• Parallel or Series Unit Procedures• Parallel or Series Operations• Parallel or Series Phases
• Copy existing recipes to easily create new ones
25
S-88 Limitations and Realistic Expectations
• If you can’t sell it, you can’t make more of it!• Decreased batch times are only realized if product demand
goes up accordingly– Especially for single product units/cells– Despite reductions in batch time, sales remained stable, and
actually declined heading into the economic recession• The Cell/Unit is still only as good as its weakest link
– Don’t forget to bolster your reliability• New processes are perfect for S-88
– Do it right the first time
