High-energy usage

Aluminium puts a high burden on the environment when it is first manufactured, due to high-energy usage. Recycled aluminium however has a much lower environmental impact. Aluminium is used in the pharmacy in tubes and in blister packs (together with PVC). 

High-energy usage After the oil extraction with solvent, the oil solvent mixture is then separated by evaporation. This requires a considerable amount of energy, and in addition safety problems might arise from the released explosive vapors. 

On-Site or Field Usage of High Energy X-Ray Systems. 

It is possible to dispense with the extraction step if the oxidation section is operated at high propylene concentrations and low steam levels to give a concentrated absorber effluent. In this case, the solvent recovery column operates at total organic reflux to effect a2eotropic dehydration of the concentrated aqueous acryflc acid. This results in a reduction of aqueous waste at the cost of somewhat higher energy usage. 

Energy usage per kg of product highly dependent on heat of vaporization of solvent and number of effects used (can be very energy intensive). 

Promethium produces beta rays (high-energy electrons). These beta rays are used to produce nuclear-powered batteries to provide electricity for spacecraft, as well as long-term usage for up to five years in regions without electricity. It also could be used as a source of portable X-rays, as a gauge to measure the thickness of various materials, and to produce special lasers that can communicate with submarines.
