Condense url11/1/2022 ![]() ![]() Swapan Basu, Ajay Kumar Debnath, in Power Plant Instrumentation and Control Handbook (Second Edition), 2019 10.2.6.2 Function of Digital signals In all these cases the condensate may still provide a better source of boiler feed than the available raw water, but it may need condensate filtration or softening plant before re-use. ![]() In some process applications condensate becomes contaminated: in sugar refining it may contain sugar, in paper manufacture and some other processes it may be contaminated with raw water, and where it feeds turbines or other machinery it is liable to contain oil or grease. The percentage condensate return is thus basic to all considerations of water management for the boiler circuit. It represents the ideal feedwater, and the higher the proportion of recovered condensate in the feed, the easier it will be to maintain the boiler water within the desired limits. Unless it has been excessively exposed to the atmosphere, condensate is also very low in dissolved oxygen. George Solt CEng, FIChemE, in Plant Engineer's Reference Book (Second Edition), 2002 19.5.3 Condensate returnĬondensate normally contains no hardness and is very low in dissolved solids. The same as oil, condensate volume is measured in barrels at the standard conditions. One of the main parameters to characterise condensate are condensate-gas factor and the pressure of the condensation onset. If the formation pressure during an oil production is not maintained by water or gas injection and formation pressure is lowered then condensate can start consolidating as a separate phase. All condensate behavior in the formation is fully defined by the formation chemistry, temperature and pressure. In an oil formation condensate can exist as dissolved in oil/connate water gas or as a separate phase. Condensate comes from an oil well as so called associate gas (wet gas) and is also refereed at certain stages as lease condensate. In some cases condensate contains small amounts of sulfur compounds.Ĭondensate low density leads to high API gravity numbers, which are in the region of 50–120 0API. Chemically condensate does contain light carbohydrates but not propane and ethane. ![]() Eldar Zeynalov, in Primer on Enhanced Oil Recovery, 2020 2.1.2 CondensateĬondensate is a mixture of light hydrocarbons with relatively low molecular weight which exists as a liquid at standard conditions (standard temperature and pressure). ![]()
