MDO and HFO prices for ships
Heavy Fuel Oil is what if refereed to as the heavies, is the long chain hydrocarbons in crude that can not be distilled at 350 F. The products includes greases, waxes, plastics, asphalts, tar etc. The HFO can be further process to separate the different products or can be cracked, a process that breaks the long chain hydrocarbons in to shorter chain hydrocarbons and distilled into LNG, gasoline, diesel, kerosene etc.

In addition to finding the "sweet spot" as the other poster indicated which is the RPM and load that the engine uses the least amount of fuel per KWm HFO reduction can also been realized by using new technology, E-Fuel. E-Fuel, reduces emissions as traditional emulsions but in the case of HFO can increase the fuel efficiency using HFO up to 38% in a rotating engines. There are two reasons that the 38% effective can be reached, the heavies don't have to be removed from HFO to prevent damage to the engine and the fuel is 43% more efferent in converting the HFO into mechanical energy.
Hypofluorous acid
HFO = Heavy Fuel Oil 380 CST = the grade of fuel oil representing viscosity, quality, etc.
66 degree Centigrade
In the new HFO he does.
The viscosity of HFO (heavy fuel oil) varies depending on its grade and temperature. Generally, HFO has higher viscosity than other fuels, such as diesel or gasoline. It has a thick, sticky consistency that makes it more challenging to flow and pump through pipelines and engines, especially at lower temperatures.
It is in use now in both Europe and America.
Most systems using R-134a as a refrigerant.
all of the answers are true
No. They are completely different refigerants. They are not interchangeable and should not be mixed.
HFO-1234yf has been tested and found compatible with automotive air conditioning systems as a replacement for R-134a refrigerant. It is also compatible with several materials commonly used in these systems, such as aluminum, copper, and polyethylene.
