  • Avoid unnecessary costs by understanding process problems before taking action

    When a piece of process equipment starts experiencing problems and producing off-spec product, every engineer’s reaction is to make a change to “fix” the problem and get it back on-spec. yet, many plants lack adequate instrumentation to completely diagnose the cause of the poor performance. Without a more complete understanding of the root cause of the problem, “corrective action” could have little effect or make the problem worse. Gathering supplemental ...
