An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, [a] and sometimes to their melting point.Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.
The process type and conditions of processing lead to greater variances between the condensates than the differences between the common wood types that are in use. [10] Variables such as feed rate, vapor residence time, particle size, oxygen infiltration, and temperature can have substantial effects on yield and composition of the condensates.
In the Russian practice, though, "mazut" is an umbrella term roughly synonymous with the fuel oil in general, that covers most of the types mentioned above, except US grades 1 and 2/3, for which separate terms exist (kerosene and diesel fuel/solar oil respectively — Russian practice doesn't differentiate between diesel fuel and heating oil ...

Mobile catering is the business of selling prepared food from some sort of vehicle. It is a feature of urban culture in many countries. [1] Mobile catering can be performed using food trucks, trailers, carts and food stands with many types of foods that can be prepared. Mobile catering is also used to provide food to people during times of ...
In many cases, the tubes of a rising film evaporator are usually between 3–10 metres (9.8–32.8 ft) in height with a diameter of between 25–50 millimetres (0.98–1.97 in). Sizing this type of evaporator requires a precise evaluation of the actual level of the liquid inside the tubes and the flow rates of the vapor and film.
A food truck is a large motorized vehicle (such as a van or multi-stop truck) or trailer equipped to store, transport, cook, prepare, serve and/or sell food. [1] [2]Some food trucks, such as ice cream trucks, sell frozen or prepackaged food, but many have on-board kitchens and prepare food from scratch, or they reheat food that was previously prepared in a brick and mortar commercial kitchen.
Marine diesel oil (MDO) is a type of distillate diesel oil. Marine diesel oil is also called distillate marine diesel. [1] MDO is widely used by medium speed and medium/high speed marine diesel engines. It is also used in the larger low speed and medium speed propulsion engine which normally burn residual fuel. [1]
