Before SRP can begin, the vessel's nuclear fuel must be removed, and defueling usually coincides with decommissioning. Until the fuel is removed, the vessel is referred to as "USS Name," but afterward, the "USS" prefix is dropped and it is referred to as "ex-Name." Reusable equipment is removed at the same time as the fuel. [citation needed]
Chemists remove gases from solvents when the compounds they are working on are possibly air- or oxygen-sensitive (air-free technique), or when bubble formation at solid-liquid interfaces becomes a problem. The formation of gas bubbles when a liquid is frozen can also be undesirable, necessitating degassing beforehand.
Sparging introduces a gas that has little or no partial pressure of the gas(es) to be removed, and increases the area of the gas-liquid interface, which encourages some of the dissolved gas(es) to diffuse into the sparging gas before the sparging gas escapes from the liquid. Many sparging processes, such as solvent removal, use air as the ...
The town previously removed the oil and fuel from the vessel. A sailboat also was up for sale at the auction, Willis said, but there were no bidders. ... the town gave the owners of the old boats ...
When producer gas is used to power cars and boats [1] or distributed to remote locations it is necessary to scrub the gas to remove the materials that can condense and clog carburetors and gas lines. Anthracite and coke are preferred for automotive use, because they produce the smallest amount of contamination, allowing smaller, lighter ...
AWTs are believed to be very effective in removing pathogens, oxygen demanding substances, suspended solids, oil and grease, and particulate metals from sewage, but only moderately effective in removing dissolved metals and nutrients (ammonia, nitrogen and phosphorus).
Hydrodesulfurization or hydrodesulphurisation (Commonwealth English; see spelling differences) (HDS), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils.
A stranded boat near Bradford Beach caught the attention of multiple passersby on their morning walks Wednesday. The abandoned boat appeared to be stuck in the sand near the rock wall between ...
