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...
