Refrigerants should not be mixed in the same recovery cylinder, as different refrigerants have varying properties and can react adversely with one another. Each refrigerant type should be recovered into its designated cylinder to ensure safety and compliance with regulations. This practice helps maintain the integrity of the refrigerants for proper recycling or disposal. Therefore, ideally, only one type of refrigerant should be recovered in a single cylinder.
Many refrigerants cause damage to the ozone layer. These are CFC's.
Chlorofluorocarbons (CFCs) are a group of refrigerants that contain carbon, chlorine, and fluorine atoms. Some common CFC refrigerants include R-12 and R-11, which are widely known for their ozone-depleting properties. Due to their environmental impact, the use of CFC refrigerants has been phased out in many countries.
Gold can be recovered from electronic scrap. Gold can be recovered from old computers, printers, mobile phones, monitors and many other electronic devices.
There are a number of different refrigerants used - typically, CFCs were used in older AC systems, and HFCs are much more common now. Many people refer to all refrigerants as Freon - this is a misnomer. Freon is a trademark name for a series of CFC and HFC refrigerants manufactured by DuPont.
Yes, many people have recovered from a coma.
Truthfully, not all bodies were recovered. There are still many service members entombed inside the USS Arizona, and many others not accounted for.
I heard only recently that 40 % of the victims were never recovered. So 1800 (approx) were recovered. The twin pools are the resting places for the 1200 others
