Shutdown of Spare Equipment

Steam jets are used to create a vacuum at a textile plant. Instead of running spare jets to maintain reliability, an automatic start system was installed for quick start-up, permitting shutdown of the spare units when not in use and resulting in a saving equivalent of 3,000 barrels of oil per year.

Energy Savings Through Waste Incineration

A distillation column (see attached sketch) at one of the chemical plants produced 4 0,000 lb/hr of highly aqueous waste (95 percent water). Incineration was the only environmentally sound method for destroying this waste, but large amounts of natural gas were required to evaporate the water so that the organic material could be destroyed. Our engineers conceived a scheme whereby a concentration still was installed that, through evaporation, reduced the waste load to the incinerator from 40,000 lb/hr to 15,000 lb/hr. The remaining 25,000 lb/hr was discharged as pure water vapor off the top of the still where it was reutilized in the distillation process as a source of heat. This installation is now in operation and is saving the equivalent of approximately 90,000 barrels of oil per year.
