Reservoir cooling

Answer Figure 15.5.2-2 shows an automatic depressurization valve that opens on excessive conditions to release the steam which passes through a turbine to drive an electric generator to provide makeup water and operate other cooling equipment. After the steam has cooled in the low pressure turbine it discharges under water in the cooling reservoir and condensed. The reservoir cools by evaporation. 

Depolymerizations of polymer and oligomer were performed by heating them at 300 u 350°C under vacuum. The products were collected in the reservoir cooled in liquid nitrogen bath and analyzed by gas-liquid chromatography. 

The more volatile component evaporates from the mobile phase reservoir —> Cool the reservoir, cover it, mix the solvents within the HPLC system even in the case of isocratic separations. 

Thus, in a real heat engine the transformation of heat into work inevitably causes the transfer of a certain amount of heat to the environment. This results in the engine s thermal reservoir cooling and the cooler (i.e., the environment) heating this is in agreement with the second law of thermodynamics.

High temperature steam cools and eventually condenses as it propagates through the oil reservoir. To maintain foam strength as the steam cools, a noncondensible gas, usually nitrogen or methane, is often added to the injectant composition (196). Methods of calculating the optimum amount of noncondensible gas to use are available (197). 

The oil 2one is fairly cool, and in a viscous oil reservoir this can result in Htde oil movement (Uquid blocking). Reverse combustion, in which oil ignition occurs near the production well, can avoid this problem. The combustion 2one moves countercurrent to the flow of air from the injection well. Oil flows through heated rock and remains mobile. Reverse combustion requires more air and consumes more oil than forward combustion. 

After the SO converter has stabilized, the 6—7% SO gas stream can be further diluted with dry air, I, to provide the SO reaction gas at a prescribed concentration, ca 4 vol % for LAB sulfonation and ca 2.5% for alcohol ethoxylate sulfation. The molten sulfur is accurately measured and controlled by mass flow meters. The organic feedstock is also accurately controlled by mass flow meters and a variable speed-driven gear pump. The high velocity SO reaction gas and organic feedstock are introduced into the top of the sulfonation reactor,, in cocurrent downward flow where the reaction product and gas are separated in a cyclone separator, K, then pumped to a cooler, L, and circulated back into a quench cooling reservoir at the base of the reactor, unique to Chemithon concentric reactor systems. The gas stream from the cyclone separator, M, is sent to an electrostatic precipitator (ESP), N, which removes entrained acidic organics, and then sent to the packed tower, H, where SO2 and any SO traces are adsorbed in a dilute NaOH solution and finally vented, O. Even a 99% conversion of SO2 to SO contributes ca 500 ppm SO2 to the effluent gas.
