In this work, an ultrasound experimental setup was designed to investigate the feasibility of using low-frequency ultrasonic waves as a substitute to reduce the consumption of chemical demulsifiers in the pretreatment of crude oil.
Integrated solar absorption cooling and heating (SACH) systems, which use solar energy to provide space heating, space cooling, and water heating, represent a promising substitute to reduce the earth's carbon emissions.
Power plants also could store backup fuel but stopped doing so after they were forced to abandon oil as a substitute to reduce emissions, Powers said.
The resistance against antibiotics becomes great threat to animals and human being, and it is meaningful to find out the antibiotic substitute to reduce the usage of antibiotics.
