6 6 CM4120 Chemical Plant Operations Lab Introduction to Chemical Manufacturing Primary Goal of Chemical Manufacturing? How does your company achieve that goal?

7 7 CM4120 Chemical Plant Operations Lab Introduction to Chemical Manufacturing Corporate Survival Skills: Must provide service or product on a timely basis Manage multiple supplier relationships Sufficient quality, consistently Manage complex customer relationships Expand existing markets Develop new products Continuing education/professional development

8 8 CM4120 Chemical Plant Operations Lab Introduction to Chemical Manufacturing Business Constraints Must maintain a level of profitability while complying with: Environmental laws Health and safety regulations Labor laws Tax laws International trade agreements Certifications or quality assurance standards Internal politics Moral and ethical standards

9 9 CM4120 Chemical Plant Operations Lab Introduction to Chemical Manufacturing Major political events changed the business climate worldwide Breakup of Soviet Union Free and open trade in western Europe and a re- united Germany NAFTA Expanding markets and infrastructure development in India, China, S. Korea, other Pacific Rim countries Formation of the European Union and the creation of the Euro

10 10 CM4120 Chemical Plant Operations Lab Introduction to Chemical Manufacturing What you did today isn’t good enough for tomorrow! Your company is driven to continuous improvement by your customers by your competitors

11 11 CM4120 Chemical Plant Operations Lab Introduction to Chemical Manufacturing Ways to improve profitability increase throughput increase on-time order fulfillment improve stability of process improve quality reduce inventory – product and feedstocks reduce maintenance costs reduce labor costs reduce production costs reduce/eliminate environmental releases reduce energy costs reduce/eliminate off-spec product

12 12 CM4120 Chemical Plant Operations Lab Introduction to Chemical Manufacturing All improvements fall into one of two categories: Improved processing and control thru Quality Management, or Increased profitability thru efficient Supply Chain Management

13 13 CM4120 Chemical Plant Operations Lab Quality Manufacturing How is Quality defined? ISO9000: The totality of features and characteristics of a product or service that bear on its ability to satisfy stated or implied need. Quality is always defined by the customer. Quality is what adds value to your raw materials.

14 14 CM4120 Chemical Plant Operations Lab Quality Manufacturing Traditional thinking: Quality costs $ higher quality higher cost no gain Current practice: Un-quality costs $ must recognize and evaluate cost/ quality relationship

15 15 CM4120 Chemical Plant Operations Lab Quality Manufacturing Costs related to quality, 4 primary categories Prevention costs Appraisal costs Internal failure costs External failure costs reference: Dr. Joseph Juran

16 16 CM4120 Chemical Plant Operations Lab Quality Manufacturing What is Quality Management? Managing systems and processes for the elimination of errors. Creating an environment for continuous improvement.

17 17 CM4120 Chemical Plant Operations Lab Quality Manufacturing Formula for a generic process: A+B=C where A=system contribution, B=human contribution, and C=desired (measurable) output manipulating A and B causes variation in C W. Edwards Deming – Variation is the enemy of quality manufacturing

18 18 CM4120 Chemical Plant Operations Lab Quality Manufacturing Deming’s 14 Principles: Quality manufacturing means “elimination of errors” 1. Create constancy of purpose toward improvement and service, with the aim to become competitive and to stay in business, and to provide jobs. 2. Adopt the new philosophy. We are in a new economic age. Western management must awaken to the challenge, must learn their responsibilities, and take on leadership for change. 3. Cease dependence on inspection to achieve quality.

19 19 CM4120 Chemical Plant Operations Lab Quality Manufacturing 4. End the practice of awarding business on the basis of price tag. Instead, minimize total cost. Move toward a single supplier for any one item, on a long-term relationship of loyalty and trust. 5. Improve constantly and forever the system of production and service, to improve quality and productivity, and thus constantly decrease costs. 6. Institute training on the job. 7. Institute leadership. 8. Drive out fear. see for morewww.deming.org

20 20 CM4120 Chemical Plant Operations Lab Quality Manufacturing What is a Process? A logical sequence of tasks that repeatedly transform inputs into outputs. Inputs may be people, information, or material. Outputs may be products, services, or behaviors.

21 21 CM4120 Chemical Plant Operations Lab Quality Manufacturing What is a System? Group of people and/or processes that are united with a common purpose. Have identifiable characteristics. Have measurable performance (quality) indicators.

22 22 CM4120 Chemical Plant Operations Lab Quality Manufacturing What is Variation? Measurable change in the system output(s). Inherent to all processes or systems. 4 types of variation: Common cause – built into the system. Special cause – assignable to an event. Tampering – result from tampering. Structural – regular, systematic changes.

23 23 CM4120 Chemical Plant Operations Lab Quality Management Tools What is Statistical Process Control? Application of statistical methods to separate common cause variation from other causes. Uses control charting to convert fluctuations in a measured characteristic into useful information. A tool commonly used in quality systems.

24 24 CM4120 Chemical Plant Operations Lab Quality Management Tools Fishbone (Cause and Effect) Diagram Viscosity variation

25 25 CM4120 Chemical Plant Operations Lab Quality Management Tools Pareto Chart Used to display the relative importance or frequency of problems or conditions A bar graph showing frequency of problem occurrence. Optionally, can have a “cumulative frequency” line and show percentage of total on bar graph.
