A systematic approach to profit optimization utilizing strategic solutions and methodologies for the chemical process industry In the ongoing battle to reduce the cost of production and increase profit margin within the chemical process industry, leaders are searching for new ways to deploy profit optimization strategies.
defines strategic planning and implementation techniques for managers, senior executives, and technical service consultants to help increase profit margins.
The book provides in-depth insight and practical tools to help readers find new and unique opportunities to implement profit optimization strategies. From identifying where the large profit improvement projects are to increasing plant capacity and pushing plant operations towards multiple constraints while maintaining continuous improvements—there is a plethora of information to help keep plant operations on budget.
The book also includes information on:
● Take away methods and techniques for identifying and exploiting potential areas to improve profit within the plant
● Focus on latest Artificial Intelligence based modeling, knowledge discovery and optimization strategies to maximize profit in running plant.
● Describes procedure to develop advance process monitoring and fault diagnosis in running plant
● Thoughts on engineering design , best practices and monitoring to sustain profit improvements
● Step-by-step guides to identifying, building, and deploying improvement applications
For leaders and technologists in the industry who want to maximize profit margins, this text provides basic concepts, guidelines, and step-by-step guides specifically for the chemical plant sector.
