Process changes, protection strategy

Electrochemical corrosion techniques are essential in predicting the service hfe ofmetal-hc components used in chemical and construction industries. They measure the corrosion rates, the oxidizing power of the environment, and evaluate the effectiveness of corrosion protection strategies. The following direct current dc electrochemical methods are discussed in this chapter linear polarization technique, Tafel extrapolation, and open circuit potential (OCP) vs. time measurements. Electrochemical impedance spectroscopy (EIS) is introduced as an alternating current technique ac. This technique uses alternating current to measure frequency-dependent processes in corrosion and estimates the change of polarization resistance. [Pg.182]

General strategy for control (Control of Substances Hazardous to Health Regulations). Identification of a hazard. Assessment of risk. Choice of control measures (including process change, substitution, segregation, engineering controls, reduced time exposure, personal protective equipment). [Pg.713]

An organization needs to develop a strategy for fire protection. This allows for cost-effective and efficient implementation and continuous improvement in fire protection systems. This strategy must be reviewed and updated periodically because of the many changes that take place within processing industries. [Pg.9]
