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.
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.
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 ...
Under pressure from fishermen and the tourist trade, [5] it was decided to pump out the oil still in the tanks, using the specialized drilling vessel Pétrel, operated by Comex. The novel solution involved sucking out the oil after injecting seawater at 90 °C (194 °F) into the tanks, to increase fluidity.
Animated sequence of how a bore evacuator works. A bore evacuator. A bore evacuator or fume extractor is a device which removes lingering gases and airborne residues from the barrel of an armored fighting vehicle's gun after firing, particularly in tanks and self-propelled guns.
Marine fuel management (MFM) is a multi-level approach to measuring, monitoring, and reporting fuel usage on a boat or ship, with the goals of reducing fuel usage, increasing operational efficiency, and improving fleet management.
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 ...
As a tank is pumped out, it is filled with inert gas and kept in this safe state until the next cargo is loaded. [95] The exception is in cases when the tank must be entered. [95] Safely gas-freeing a tank is accomplished by purging hydrocarbon vapors with inert gas until the hydrocarbon concentration inside the tank is under about 1%. [95]
