A 1.5-liter and a 10-liter AdBlue container Hino truck and its SCR next to the diesel particulate filter (DPF) with regeneration process by the late fuel injection to control exhaust temperature to burn off soot [1] [2] Passenger car using an AdBlue pump. Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a ...
By attaching a small gas bubble to an oil droplet, the density of the droplet decreases, which increases the rate at which it will rise to the surface. Therefore, the smaller the gas bubbles created the smaller the oil droplet floated to the surface. Efficient flotation systems need to create as many small bubbles as possible.
The engine needs a fuel tank and an automatic controller that will start the booster pump when it is needed. A small auxiliary electrically-powered booster pump (called a "jockey pump") is often included in the system to maintain the sprinkler pipes at sufficient pressure, without requiring startup of the large diesel engine.
Imhoff tanks are being superseded in sewage treatment by plain sedimentation tanks using mechanical methods for continuously collecting the sludge, which is moved to separate digestion tanks. This arrangement permits both improved sedimentation results and better temperature control in the digestion process, leading to a more rapid and complete ...
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.
By mid-1948, Aerojet had selected centrifugal pumps for both liquid hydrogen and liquid oxygen. They obtained some German radial-vane pumps from the Navy and tested them during the second half of the year. [6] By the end of 1948, Aerojet had designed, built, and tested a liquid hydrogen pump (15 cm diameter).
The V-2 used an alcohol/LOX liquid-propellant engine, with hydrogen peroxide to drive the fuel pumps. [ 7 ] : 9 The alcohol was mixed with water for engine cooling. Both Germany and the United States developed reusable liquid-propellant rocket engines that used a storeable liquid oxidizer with much greater density than LOX and a liquid fuel ...
Oil and Natural Gas Refinery in Turkey. In an oil and gas production, flash-gas is a spontaneous vapor that is produced from the heating or depressurization of the extracted oil mixture during different phases of production. [1] Flash evaporation, or flashing, is the process of volatile components suddenly vaporizing from their liquid state.
