YPOV: ChE Problem Solving: The Double Diamond Approach

YPOV
March
2020
Yogi Paturu

Imagine you are a new process engineer and notice that a distillation column is producing product at 99% purity. The product specification, however, is 94% purity, and you know that exceeding this mandate is a financial loss. The simulation shows that decreasing steam input by 2,000 lb/hr can reduce the purity to 95%. It is your responsibility to determine a lasting solution.

A problem-solving approach popular with user-experience (UX) designers, called the double diamond design process (1), can be applied to solve chemical engineering problems such as this distillation conundrum. The framework is a nonlinear approach that consists of four stages — discover, define, develop, and deliver — that problem-solvers can navigate back and forth between to reach a solution...

Features

Process Intensification in Theory and Practice

In the January 2000 issue of CEP, Andrzej Stankiewicz and Jacob Moulijn introduced readers to the concepts of process intensification (PI) and how PI could transform chemical engineering and process development.

The Principles and Domains of Process Intensification

Apply the fundamental principles of process intensification to the four domains of PI — spatial, thermodynamic, functional, and temporal — to identify possible PI opportunities.

Selecting Process-Intensified Equipment

Use this approach to evaluate PI options and compare technologies.

Process Modeling of Intensified Chemical Processes

Before the benefits of process intensification can be fully realized, a multitude of advances in process modeling will be necessary.

Sustainable, Modular Chemical Production in Africa

Developing countries have an opportunity to leapfrog old technologies and adopt advanced manufacturing techniques such as modular chemical process intensification.

Getting Incident Investigations Right

An incident unfortunately cannot be undone, but a properly executed safety investigation can prevent similar incidents.

Prevent Corrosion and Ensure Reliability

Once integrity operating windows (IOWs) have been established for variables that impact corrosion, follow these ten steps to implement a successful IOW program.

Interpersonal Skills for Chemical Engineers

Don’t be a grouch — learn to get along with others.

Technical Entity Trends: Polymers and Textiles: You Are What You Wear

Polymers and textiles are an integral part of society. What we wear and what our clothing can do for us has helped define humanity for most of history. Clothing serves many purposes — fashion, protection from the elements, warmth, and identification. It is often an indicator of gender, social...
