Heat exchangers condensation

In oil and gas refinery appHcations, titanium is used as protection in environments of H2S, SO2, CO2, NH, caustic solutions, steam, and cooling water. It is used in heat-exchanger condensers for the fractional condensation of cmde hydrocarbons, NH, propane, and desulfurization products using seawater or brackish water for cooling. 

Thermal and mechanical design of heat exchangers (condensers and evaporators) is presented earlier in this section.

Where possible, and while the cleaning solution is recirculating through the cooling system, it may prove useful to back-wash (back-flush) any heavy-duty heat exchangers, condensers, etc. as a further means of providing the best possible clean. 

Of course, there is additional capital investment in the distillation column and its associated heat exchangers (condenser and reboiler) and most importantly, there will be an energy cost to provide heat to the reboiler. We neglect any energy cost in the...

FIGURE 10.1 Flowsheet for the electric furnace process for the production of elemental phosphorus. Phossy water from the phosphorus phase separator (sump) is normally maintained in a closed-circuit holding pond system which also provides the feedwater for the phosphorus direct contact condenser. Some facilities have a further indirect, heat exchange condenser for the carbon monoxide stream, after the direct contact condenser. 

First of all it is important to analyze the response rate to transient or dynamic requirements of all individual sub-systems, included the stack [50]. The electrochemical phenomena that occur inside the fuel cell stack are very fast, while water and thermal management systems show an enormous inertia with respect to typical vehicle requirements. In particular working temperature is a crucial parameter for designing BOP components such as heat exchangers, condensers and humidifiers devices to match dynamic requirements. Equation 4.8 could be used to demonstrate that the thermal capacity of the whole stack limits the dynamic in temperature change. 

From a systems point of view, the overall reactor can be considered a system, with the different parts of the entire reactor, e.g. the catalyst bed, cooling (or heating) tubes, external heat exchangers, condensers... 

A dynamic model of a distillation column can be assembled from simpler units, as trays, heat exchangers (condenser, reboiler), reflux drum, valves and pumps (Fig. 4.5). Tray modelling has to answer two issues (1) accurate description of material and energy holdup, and (2) accurate pressure drop calculation.
