Process designers should always consider energy conservation including:
Using waste heat to preheat process streams or do other useful work
Reducing the energy requirement for pumping by using larger diameter pipes or cutting down frictional losses Reducing the energy use in buildings through more efficient heating, cooling, ventilation, and lighting systems Saving energy by using more efficient equipment. Both electric motors and refrigeration systems can be improved through modernization and optimized control technology.
Conserving process energy through the insulation of process tanks, monitoring, and regulating temperatures to reduce energy cost and resource use in energy generation Using high-efficiency motors and adjustable-speed drives for pumps and fans to reduce energy consumption Reducing energy use through proper maintenance and sizing of motors
Renewable energy sources such as the sun, wind, and water offer electricity for the cost of the generating equipment. Surplus electricity can often be sold back to the utilities to offset electrical demand. A decrease in the demand for electricity resulting from the use of renewable resources increases the environmental quality.
