HYBRID gas dew point system

HYBRID gas dew point system

A hybrid system comprising 120mm of IKO enertherm ALU insulation above the roof deck and VCL, and 100mm of the same product below will provide a U-value of around 0.11 W/m²K. By comparison, a warm roof would require 180mm of IKO enertherm ALU insulation to achieve the same U-value – raising the overall roof height by 60mm.

  • Advanced Analysis of Dew Point Control Unit of Hybrid

    In this paper, an advanced analysis of a novel hybrid compression-absorption refrigeration system (HCARS) for natural gas dew point control unit in a gas refinery is presented. This unit separates the heavy hydrocarbon molecules in the natural gas, which is traditionally carried out by natural gas cooling in a compression refrigeration cycle (CRS).

  • Raypak – Hybrid Heating Systems

    It is a law of physics that the flue products have to be cooled below their dew point (the temperature at which condensation will take place) in order to operate in the condensing mode associated with over 90% efficiencies. This means that the incoming water to the heat exchanger must always enter below the dew point of the flue products.

  • Hydrocarbon dew point - Wikipedia

    The hydrocarbon dew point is the temperature at which the hydrocarbon components of any hydrocarbon-rich gas mixture, such as natural gas, will start to condense out of the gaseous phase. It is often also referred to as the HDP or the HCDP. The maximum temperature at which such condensation takes place is called the cricondentherm. The hydrocarbon dew point is a function of the

    A dew point analyzer measures the amount of moisture present in a gas to determine the theoretical temperature at which the moisture in the gas will condense (the saturation point). Although dew point is related to the temperature and the pressure of the gas, the dew point of a gas remains the same regardless of the actual temperature of the gas. For example, a gas at room
