Sodium hydroxide (NaOH) is a white, translucent crystalline solid that is widely used in the chemical process industries (CPI). NaOH is often referred to as caustic soda, due to its corrosive action on many substances: it decomposes proteins at room…
Switching from one fluid to another in a heat transfer system requires an engineering evaluation. Here is what to include In well-designed and well-maintained heat transfer systems, heat transfer fluids generally last for a long time and function as intended.…
Taking a modular approach to capital projects offers a pathway for companies to be proactive, rather than reactive, as they manage project risk in the time of COVID and potential similar disruptions in the future It has been more than…
Developments in laser technology and significantly increased computing power are making process analyzers available for new applications and even for closed-loop control Process analytical technology (PAT) has undergone rapid development in recent years. Further developments in laser technology, the miniaturization…
Combining process analytical technology (PAT) and the cloud for next-level productivity Process analytical technology (PAT) enables manufacturing and processing companies to continuously enhance their competitiveness in an increasingly fast-paced and demanding market (see part 1, “Process Analytical Technology Advances,” pp.…
Industrial evaporator heat-transfer surfaces are either tubular or flat plates, packaged into a variety of evaporator types, as outlined here. Batch evaporators Batch evaporators are vessels with a heating jacket or internal coil, an overhead condenser, a condensate receiver, and…
Polylactic acid (PLA, polylactide; Figure 1) is a thermoplastic aliphatic polyester that is derived from a number of renewable starting materials, such as starch and sugarcane, via bacterial fermentation. PLA is semicrystalline or amorphous, rigid, resilient and an ultraviolet-light-resistant material,…
New developments in augmented reality can help plant operators fix critical issues while limiting the number of outside visitors entering the facility Reducing risk is an important goal for any plant or petroleum refinery to maintain the health and safety…
A look at how advanced analytics facilitates and improves process safety efforts within the chemical process industries (CPI) Simply by the nature of some of the chemicals used and the associated complex processes involved, chemical plants can be hazardous. With…
In all phases of a valve’s lifecycle — from fabrication to decommissioning and storage — corrosion protection is essential Corrosion can be a serious source of valve damage, and it can often result in costly leakage, failures and repairs or…
