Advanced dew-point control system in two-pressure humidity generator to stabilize dew-point generation in low dew-point range

نویسندگان

چکیده

We developed a novel dew-point control system [advanced (ADCS)] in primary standard humidity generator based on the two-pressure technique. In ADCS, actual vapor–liquid equilibrium temperature of water was estimated for control, and pressure inside main saturator controlled by adjusting variable opening an expansion valve. Using periodic variation (oscillation) dew point observed low range greatly reduced. The stability generation improved 23-fold.

Advanced Analysis of Dew Point Control Unit of Hybrid Refrigeration Systems in Gas Refineries

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). The power input required for the refrigeration...

A micro dew point sensor with a thermal detection principle

We present a dew point temperature sensor with the thermal detection of condensed water on a thin membrane, fabricated by silicon micromachining. The membrane (600 × 600 ×∼1 μm3) is part of a silicon chip and contains a heating element as well as a thermopile for temperature measurement. By dynamically heating the membrane and simultaneously analyzing the transient increase of its temperature i...
