Cold traps — steam traps that no longer drain condensate — are often ignored in lieu of less-critical leaking traps, until a catastrophic event, such as a plant shutdown or personal injury, occurs. Use historical data to accurately estimate the annual cost of these cold traps to justify their swift repair.

Two new views for production modeling are introduced - production flow networks and production flow maps - that focus on unit operations and feedstocks, respectively.
Decision-makers often require cost estimates for products and processes at the earliest stages of development — when many cost-determining factors remain uncertain. Identifying variables that impact cost estimates, and putting them in context, will...
