Frost is one of the atmospheric phenomena which seriously threaten crop production. It also causes numerousaccidents in mountainous roads. In this research the Spatial Synoptic Classification SSC method was employed toclassify the type of air masses. For the classification, such meteorological data as: temperature, dew point, mean sealevel pressure, cloudiness, direction and speed of wind were ...

Dew Point Control Unit (DPCU) merupakan salah satu unit utama yang penting dalam proses pemurnian gas alam. Terbentuknya metana hidrat di DPCU menjadi masalah dihadapi ketika suhu operasi diturunkan serendah mungkin pada tekanan tinggi. Untuk mencegah terjadinya pembentukan tersebut, diperlukan adanya injeksi glycol. Jenis glycol digunakan oleh Gajah Baru Central Process Platform (GBCPP) milik ...

An indirect evaporative cooler that uses a Maisotsenko (M) Cycle has the potential to be green and sustainable solution for managing building’s cooling demand since it can attain sub-wet bulb temperature without humidification. This study presents design simulation analysis of crossflow using COMSOL Multiphysics software various ambient conditions. The cooler’s performance was evaluated by vary...
