Dehumidification >> When To Use A Dehumidifier In Your Home

The water evaporation and condensation occurred interior the separation unit, resulting in a direct reuse of latent heat released by water condensation. The energy of the system was calculated by When To Use A Dehumidifier In Your Home performing energy balance with the following equation: where is the water flow rate, kg/min. G is the flow rate of carry air, LPH. Cw is specific heat capacity of water, 4.18 is specific heat capacity of air, 1.006 kJ/(kg.). is temperature is specific heat of vaporization of water, 2260 kJ/kg.
Loss is defined as heat loss rate during the operation process, kJ/hr. When To Use A Dehumidifier In Your Home The Tw-ref and Tair-ref are the reference temperature of water and air respectively, both at in this study. The heat balance was calculated from equation and the results are summarized in Table 4-2. The humidification-dehumidification operation results in the formation of a temperature gradient along the separation unit: the top has the highest temperature while the bottom has the lowest temperature.
The temperature gradient varies with the feed water When To Use A Dehumidifier In Your Home temperature and feed flow rate. As shown in Table 4-2, in circumstances of low water flow rate or low operating temperature, the outlet temperatures are lower than those at the inlets because of the evaporation provoked cooling effect. Increasing feed water temperature or feed flow rate increases the temperature of the whole system as well as outlet air and liquid.
 As a consequence, the heat loss caused by water evaporation When To Use A Dehumidifier In Your Home and radiation will increase. Even though, the energy consumption for purifying unit produced water will decrease, resulting in enhanced energy efficiency and water recovery as shown in Figure 4-6. Also energy lost of the separator unit with built-in capillary tube is much less than copper tube separator, because the larger heat exchange area can accelerate heat transfer to achieve reduced energy loss.
 The coal bed methane produced water sample was When To Use A Dehumidifier In Your Home obtained from local water disposal facility at Farmington in New Mexico. The original produced water contained large number of suspended particulates, floating oil droplets and dissolved components. A coarse filtration with 100 mm filter paper was first carried out. The purpose of the coarse filtration was to remove the large particulates and oil droplets which can potentially block the microbore water distributor.
Figure 5-1 shows the picture of When To Use A Dehumidifier In Your Home produced water filtration cake. The orange and dark yellow color on the white filter paper is suspended particles accumulated [Lu, 2008]. The filtered produced water still has high concentration of particulate suspension which present as light yellow color. A dynamic light scattering particle analyzer was deployed for study of particle size distribution of the produced water. Figure 5-2 gives the particle size distribution of the filtrated produced water.
The produced water had a total dissolved solid (TDS) of 1.98—104 mg/L and total organic carbon (TOC) of 470.2 mg/L. Table 5-1 gives the chemical composition of major dissolved components in the produced water and the total suspended particles. 1 Ion removal When To Use A Dehumidifier In Your Home efficiency for produced water Produced water desalinations by humidification-dehumidification process were carried out at an air flow rate of 1000 LPH and water flow rate of 40 mL/min. The water temperatures were varied from 60 to 80 .
 The purified water samples were collected at a time interval of 3 hours. Each separation was running for over 12 hours until three consecutive water samples shown identical water productivity. Figure 5-3 gives the individual ion removal efficiency of the produced When To Use A Dehumidifier In Your Home water as a function of feed water temperature. The ion removal efficiency of NH4 +39 declined from 97.4% to 95.4% as water temperature increased from 60 to 80 . In aqueous solution, ammonium ions exist at equilibrium with ammonia (NH3 + H2 O↔NH4 + +OH- ).
 Increasing temperature drives the reaction to the left side due to the exothermic reaction. As a result, more ammonia will evaporate with air and condensate to the clean water upon subsequent cooling. When To Use A Dehumidifier In Your Home All other ions show >98% removal efficiency, resulting in a decline in total dissolved solid from 1.98104 mg/L to 92.1 mg/L at 60 . Presence of ions in the purified produced water is explained by the mist formation during air-enhanced water evaporation process.
 Small water droplets will be carried with When To Use A Dehumidifier In Your Home by the counter flowing air stream and precipitate in the purified water upon cooling. Ion removal efficiency, % Temperature, o C Na+ NH4+ K+ Mg2+ Ca2+ ClSO42- Total dissolved solid in purified water and overall ion removal efficiency at different operating temperatures. 5.2 Organic removal efficiency for produced water Presence of organics in produced water was quantified by concentration of total organic carbon.
The produced water sample treated by a coarse filtration had a TOC of 470.2 mg/L. Over 95% of organic carbon was removed by the humidification-dehumidification When To Use A Dehumidifier In Your Home process with a decline of TOC from 470.2 mg/L to 21.5 and to 17.8 mg/L at 60 and 80 , respectively. The organic components in produced water typically contain fatty acid (~300 mg/L), polycyclic aromatic hydrocarbons (PAHs, ~5 mg/L), phenols (~10 mg/L), and volatiles such as benzene, toluene and xylene (BTX, ~8 mg/L) [Hansen et al., 1994; Santos et al., 1997].
The organic composition varies over the lifetime of oil/gas production. Other factors such as temperature, production history, and type of produced water also show influences on organic composition in produced water. Generally, produced waters from gas When To Use A Dehumidifier In Your Home field or CBM production have a higher concentration of volatile hydrocarbons than those in oilfield.
