Fuel polishing. Fuel polishing is the technical cleaning process used to remove or filter microbial contamination from oil and hydrocarbon fuel in storage. It is essentially the removal of water, sediment and microbial contamination from such fuels as diesel, red diesel and biodiesel. This fuel contamination, also known as 'fuel bugs', or ...
Ultrasonic cleaning. Ultrasonic cleaning is a process that uses ultrasound (usually from 20 to 40 kHz) to agitate a fluid, with a cleaning effect. Ultrasonic cleaners come in a variety of sizes, from small desktop units with an internal volume of less than 0.5 litres (0.13 US gal), to large industrial units with volumes approaching 1,000 litres ...
Second revisit of jobs involving tight spaces: inspecting abandoned mineshaft ("Abandoned Mine Plugger"), concrete truck cleaner ("Termite Controller"), cleaning a buoy ("Buoy Cleaner"), cleaning grinder sump pump on fish processing ship ("Floating Fish Factory"), cleaning elevator shaft ("Dirty Jobs of the Big Apple"), aerial tram maintenance ...
The WABCO 3200 was a rare example of a tri-axle haul truck configuration A medium sized haul truck, the 214-short-ton (194 t; 191-long-ton) Caterpillar 789 [1]. Most haul trucks have a two-axle design, but two well-known models from the 1970s, the 350T Terex Titan and 235T WABCO 3200/B, had three axles.
Because of that, this type of truck is frequently configured to take advantage of local weight limitations to maximize the cargo. For example, within the United States, the maximum weight limit is 40 short tons (36.3 t; 35.7 long tons) throughout the country, except for specific bridges with lower limits. Individual states, in some instances ...
The gel points of some common petroleum products are as follows: #1 diesel fuel: 15.5 °F (−9.2 °C). #2 diesel fuel: 17.5 °F (−8.1 °C). Heating oil: 16.0 °F (−8.9 °C). Kerosene: −40.0 °F (−40.0 °C). For the petroleum product to flow again, it needs to be brought above the gel point temperature to the ungel point, which is ...
Propane does not burn as hot as acetylene in its inner cone, and so it is rarely used for welding. [12] Propane, however, has a very high number of BTUs per cubic foot in its outer cone, and so with the right torch (injector style) can make a faster and cleaner cut than acetylene, and is much more useful for heating and bending than acetylene.
Step 5: Neutralize the Acid. Once you've removed the rust, rinse the object with clean water to remove any remaining vinegar-and-salt residue and place it back into the container with fresh water ...
