Condensate handling system

Condensate Handling System. The condensate from the LT system is separated into light and heavy organic compounds and water. The aqueous phase (water) is treated by carbon adsorption and recycled to the LT process. The organic phases are disposed of at an off-site permitted facility. The condensate handling system is described in this subsection. 

Another example of an unsteady state condensible blowdown system is the design for a phenol condensible blowdown tank. A blowdown tank is used in phenol treating plants to handle streams containing phenol and heavy hydrocarbons (lubricating oil stocks). The blowdown tank is illustrated in Figure 4. The design basis is as rollows ... 

The sample handling system is diagrammed in Figure 3. As shown, the concentrations of oxygen, carbon monoxide, and carbon dioxide were on a dry basis because the water was removed. The water vapor analyzer did not function properly because condensation occurred in the instrument when water vapor was too high, often exceeding 20 percent. By using some approximations in the calculations, we did not need the exact concentration of water. 

A vacuum pump should be scrupulously protected from corrosive vapors and materials which will be absorbed in the pump oil or condense in the pump. For most laboratory operations a low-temperature trap is employed for this purpose, and in the case of fluorine handling systems a soda-lime trap is used to neutralize the corrosive gases. Despite these precautions, the pump oil does eventually break down and become contaminated. Regular oil changes should be scheduled for a pump at about yearly intervals for a well-protected pump and more often for pumps which are not well protected. 

The QCL approach discussed thus far in this chapter provides a good approximation to the quantum dynamics of condensed phase systems. Most often other approximate quantum-classical methods, such as mean field and surface-hopping schemes, have been commonly employed to treat the same class of problems as the QCLE. These methods are attractive due to their computational simplicity however, many important quantum features, such as quantum coherence and correlations, are not properly handled in these approaches. In this section we discuss these methods and show that starting from the QCLE, an approximate theory in its own right, further approximations lead to these other approaches. 

Humidification systems should be well drained. No condensate should accumulate in air-handling systems. 

Using the roasters as the addition point carries its own problems. If too much of the halides is eliminated in the roasters, we will need to increase the scrubber solution bleed to minimize corrosion. Corrosion will also occur in the gas handling system, especially where the temperature falls below the condensation point of hydrochloric and hydrofluoric acids. The heat balance difficulties in the roasters is atfributable to the increased feed rate. Heat removal achieved by the addition of moist oxide offsets the use of direct injection water in the roasters. The composition of the oxide material also poses a problem as roaster feed. Because the oxides... 

The vacuum applied to all stages should be the highest level to be used in operation. Condensers, circulating pumps, and condensate removal systems can be used to handle the water evaporated during the test. Under no circumstances should the absolute pressure go below 0.6 kPa, where evaporative cooling of the water will take the temperature to the freezing point. 

Due to the necessity of producing a condensed volume, the content of this book has been devoted to a limited part of physics and physical chemistry that excludes more complicated systems. More sophisticated Formal Objects that are the distributed dipoles and systems with assemblies of these objects have not been studied further. These concepts enable us to handle systems with several energy levels that are of paramount importance in condensed matter physics and in many other fields. The Maxwell distribution of velocities in a gas is one of the important systems that are modeled with this Formal Object. 

The major components of the mass spectrometer are a gas-handling manifold that enables the gas to be transferred from the ovens to the ion source, the ion source that consists of an electron impact source, magnetic mass analyzer with gap field of 6500 G, four different EM detectors, and an ion pump to ensure low pressure for the EMs. The gas handling system also included a controlled leak valve that could obtain Martian gas and feed the gas directly into the mass spectrometer for analysis. All the tubes in the gas handling system were heated to 35 C to ensure that there is no condensation of water and other volatile vapors on the hardware. 

Volume reduction of concentrated evaporator bottoms, which may include boric acid wastes, laundry wastes, chemical wastes, and other floor drain wastes, is accomplished in the radwaste volume reduction system. The major components of the system are the crystallizer chamber and recirculation system, condenser, and vacuum pump system. The crystallizer chamber consists of a conical tank and an inner circular baffle to separate solid crystals from a clear recycle stream. Combustible wastes such as clothing, filter cartridges, and wood are volume-reduced in the radwaste incinerator. Solidification of volume-reduced wastes and other low-level radioactive wastes, such as spent resins and contaminated tools, is performed in the cement solidification system. The major components of the cement solidification system include the high shear radwaste mixer, waste dispensing system, flush water recycle steam, cement storage and feed system, and the container handling system. 

Chlorine from PVC separators forms volatile lead chloride, which vaporises in the lower shaft and condenses in the upper shaft, forming a recycle loop as well as wall accretions. Some lead chloride reports to flue dusts, again causing accretions in the gas handling system, and collected dusts must be leached for removal of chlorine before recycling to the furnace feed. 

The scope of Safestore decommissioning, as licensed in March 1994, will be extended by three supplements, comprising mainly the dismantling of (1) the fuel handling system, coolant circulators, and interspace convection pipe, (2) the coolant purification system, and condensation coolers, and (3) the shutdown rod system. The goal is to clear the containment from all auxiliary systems and to seal the outer reactor vessel until the end of 2001.
