    From Treon Verdery@21:1/5 to All on Thu Mar 2 08:28:29 2023
    what happens to MTBI ***J when messy people raise them and never tell them to clean their room? Has this happened to you?

    Tooth whitening lasers could lasers etch diffraction based blue orwaveguide optics blue onto actual teeth or a plastic coating on teeth? compare PRK popularity.

    research improving the fuel (energy) efficiency at oil refineries

    the combined output of all small refineries was slightly greater than all of Texas.
    hydrogen growth supporting desulfurization is growing

    is it possible to exceed vacuum distillation efficiency with clingy gas that pulls no? because of pvnrt n and possibly r components microdropets with high vacuum resistance could pull (van der walls) but not gas

    Side processes that are used to condition inputs and/or produce hydrogen or by-products include crude conditioning (e.g., desalting)
    The principal energy consuming processes in refineries, in order of overall energy consumption in the United States, are the crude (or atmospheric) distillation and vacuum distillation units, hydrotreaters, reformer, alkylate production, catalytic
    crackers and hydrocrackers
    lpg, light vapors, and gas are the energy sources of refineries
    coking is the source of refinery fuel oil, which likely is sort of near a third a source than refinery gas

    yes because a) thermal conduction into liquid via gas is faster than
    through chamber walls and b) the evaporating surface area is larger and
    c) if the vapour pressure of the distillate is very low so there is free molecular flow (pv=nRt doesn't apply) the vapour next to the surface can
    be swept away reducing reabsorption see diffusion pump

    d) the flow of carrier gas can sweep the evaporand away even if there is
    no free molecular flow e) why can't there be van der Waals forces in vapours/gases?
