Hydroelectric power is a reliable renewable energy source, accounting for about 17% of the world’s energy. With countries around the world actively expanding capacity or looking to do so in the near future, hydroelectric power will continue to play a key role in the rise of renewable energy production. Hydroelectric power plants utilize two main types of turbines: impulse and reaction.

Coke oven main pressure control is a critical control application for the safe operation of coke making. A plant’s actuator not only must position the cross-over valve to achieve a pressure of 12+/-1 mmWC, but it must avoid pressure spikes from volatile gases soon after coal charging, as shown in Figure 1. If the actuator is slow to respond, the collection main and coke oven gas pressure will increase and leak toxic gas at the oven doors. If the actuator overshoots, the coke oven pressure can decrease to a vacuum, entering oxygen in air which ignites in the over. Both pressure scenarios present major safety concerns.

Steel production is vital to many industries around the world. Some industries include general construction, machinery manufacturing, automotive, marine, and transportation. The world needs large volumes of high quality steel to sustain the high demand. This is especially true during times of economic growth. The blast furnace is a key component of many integrated steel mills. A chemical reduction process occurs within the blast furnace.

Hydroprocessing in the O&G refining industry refers to two separate, yet similar, processes: hydrocracking and hydrotreating. The hydrocracking process converts a variety of petroleum fractions, including oil recovered from solvent extraction of petroleum residues, into more valuable, lower-boiling fuel products. Hydrotreating refers to the process of upgrading the quality of petroleum distillate fractions, such as catalytic and thermally cracked distillates, by decomposing the contaminants with a negligible effect on the boiling range of the feed.

Reliability stands at the forefront of any piece of equipment, regardless of the industry. Reliability can mean the difference between a high performance process that meets required throughput demands, and a process that is wrought with downtime and high operational costs. Reliability can also mean the difference between worker safety and the risk of danger.

Mineral processing plants have some of the most severe and demanding installation environments. These harsh environments are extremely challenging for equipment within critical plant process control applications. Controlling flashing liquids or slurries requires an actuator capable of producing large output forces and torques with accurate and repeatable positioning.
