Process steam refers to steam generated and used within industrial processes to transfer heat, drive chemical or physical processes, and enable operations such as sterilization and drying. It is distinct from utility or power-generation steam, which is primarily used to generate electricity or provide space heating. Process steam is produced in boilers or similarly rated heat sources and delivered through a dedicated distribution system to process equipment.

Steam quality is a key consideration. Steam can be saturated, containing some liquid water, or superheated to a higher temperature. The dryness fraction, or steam quality, affects heat transfer efficiency and the potential for equipment corrosion or scaling. Lower-quality steam may require larger equipment or more protective design, while high-quality steam improves thermal performance but can be more costly to produce.

A typical process-steam system includes a boiler or steam generator, steam drum or chamber, economizer to recover heat, a deaerator to remove dissolved gases, and a distribution network comprising insulated pipes, control valves, and condensate-return lines. Steam traps, vents, and condensate receivers help manage condensate and recover energy for reuse. Effective control of pressure, temperature, and flow is essential to meet process requirements while minimizing energy use and water losses.

Common applications span chemical processing, petrochemicals, food and beverage, pharmaceuticals, paper, textiles, and oil and gas. Process steam supports distillation, reaction heating, drying, sterilization, and cleaning-in-place operations. Safety and maintenance are critical due to high temperatures and pressures; proper water treatment to prevent scale and corrosion, regular boiler inspections, and reliable safety devices are essential.

Environmental and efficiency considerations focus on reducing fuel use, recovering condensate, insulating piping, and optimizing steam-usage practices to lower emissions and costs.
