Liquefaction continued mechanism

The explosive properties of liquid methane-oxygen mixtures were determined [8], Dining investigation of an explosion in a portable air liquefaction-separation plant, hydrocarbon oil was found in a silica filtration bed [9], The mechanism of slow heterogeneous accumulation of hydrocarbons dissolved in trace amounts in liquid oxygen on the liquid evaporator surfaces is discussed. It was concluded that months of continuous evaporation would be required to attain explosion-hazardous levels in real evaporators [10],... 

In order to further elucidate the mechanism of phenol liquefaction of wood, several experiments have been continued. From these negligible conversion of wood into gaseous substances during the liquefaction treatment, lowering... 

Mechanical Relief Devices. The water seals discussed above in Section 9.1.10.1 are effective only at very low differential pressures. After the compression of chlorine, and particularly in liquefaction and storage systems, more conventional relief devices, rupture discs and pressure relief valves, are used. With some fluids, there is a simple choice to be made between discs and valves. While the former are less likely to permit bypassing of small quantities of fluid, they are destroyed when they open. A release will continue even after the pressure on the system drops below the set point of the disc. Relief valves have the opposite characteristics.
