Evaporator merupakan bagian dari unit pengolahan di kilang Pusat Pengembangan Sumber Daya Manusia (PPSDM) Migas Cepu, yang berfungsi untuk proses pemisahan uap minyak dengan cairannya atau fraksi berat ringannya. Untuk mengetahui apakah berjalan dalam evaporator sudah baik belum, dapat dilihat efisiensinya, sehingga dilakukan perhitungan neraca massa dan energi pada 
 itu sendiri. Dari did...

The degree of bubble bursting at the inlet an evaporator is key factor to determine size injection noise capillary outlet. In this study, by using theory cavitation dynamics, transition tube between and improved suppress entrance evaporator, so as reduce jet outlet capillary. influence aeration structure on reduction a refrigerator (Haier BCD-520) was studied numerical simulation, experiments w...

This paper presents an interactive finned-tube evaporator and condenser design program, EVAP-COND (ver. 3), which incorporates a computational intelligence module, ISHED (Intelligent System for Heat Exchanger Design), for optimization of refrigerant circuitry. This paper presents ISHED’s design, its function, the parameters controlling an optimization run, selected examples of ISHED experimenta...

The efficiency of treatment of synthetic and semi-synthetic waste oil-in-water (O/W) emulsions by vacuum evaporation is evaluated. A previous destabilisation/centrifugation stage increases the quality of the final aqueous effluent. However, proper selection of a coagulant salt or flocculant is required. A comparison of laboratory-scale evaporation results and those obtained in an industrial eva...

A theoretical study is conducted to explore the effect of different parameters on the performance of a Loop Heat Pipe (LHP). These parameters are evaporator temperature, condenser temperature, total mass charge, the tube size of piping system, and pumping distance between evaporator and condenser. This paper pres ents a steady state model that describes the thermodynamics, heat transfer, and fl...

The application of tracer techniques to the sugar industry is reviewed. This includes the investigation of residence time distribution in clarifiers, evaporators, continuous pans, crystallizers and fluidized bed dryers; the flow split in diffusers and evaporator vessels; leak detection; measurement of entrainment in vacuum pans and determination of system volumes such as cooling water ponds.

The authors imparted the main concept of infochemical communication and its realization in the first micromachinebased chemoemitter. We present herein details on the microfabrication and functionality of its elements, particularly the biomicroreactor and the evaporator. The functionality of the integrated chemoemitter has been evidenced in an electrophysiological assay using antennae of male Sp...

This paper describes the complete integration of a fuzzy control of multiple evaporator systems with the IEEE 802.15.4 standard, in which we study several important aspects for this kind of system, like a detailed analysis of the end-to-end real-time flows over wireless sensor and actuator networks (WSAN), a real-time kernel with an earliest deadline first (EDF) scheduler, periodic and aperiodi...

An experimental investigation of the performance of thermosyphons charged with water as well as the dielectric heat transfer liquids FC-84, FC-77 and FC-3283 has been carried out. The copper thermosyphon was 200 mm long with an inner diameter of 6 mm, which can be considered quite small compared with the vast majority of thermosyphons reported in the open literature. The evaporator length was 4...
