The control for all of these could be local / remote as answered by Josh Velson.

Jan 13, 2014· In chemical process plants, the electricity demand is generally determined by the work or energy required for compression, pumping, air cooling, lights, and many other items. This electricity often times is purchased from local electricity providers, but many plants generate their own electricity via sophisticated processes.

Apr 01, 2006· Hydrogen is widely employed for hydrogenation and other purposes in chemicals manufacture, petroleum refining and other chemical process industries (Hydrogen: The Real Action Is Today, CE, February, pp. 28ff), and it holds promise as a fuel.

During a chemical reaction it is very important to know the concentrations of different chemical species to monitor (inprocess control) and also optimize certain chemical steps. Besides using offline methods in the laboratories, we possess in our production units a wide variety of inline analytical systems for immediate response to control ...

Process flow diagrams (PFDs) are used in chemical and process engineering. These diagrams show the flow of chemicals and the equipment involved in the process. Generally, a Process Flow Diagram shows only the major equipment and doesn't show details. PFDs are used for visitor information and new employee training.
