The problem of automating the thermal calculation a reactor for synthesis sulfur-containing sorbent wastewater treatment from heavy metal compounds using chlorlignin is considered. A formal description algorithm and block diagram are given; interface program written in C#, displaying results heating working mixture, determining amount heat suspension, transfer coefficient medium to wall, mass f...

A tubular pilot scale fixed-bed reactor for the Fischer–Tropsch Synthesis (FTS) was simulated to numerically demonstrate the conversion of synthesis gas (CO+H2) to higher hydrocarbons over an iron based catalyst. The reactor was a 3.1 cm diameter and 2.75 m length steel tube. The feed temperature were between 563583 K. Saturated water was employed to control the peak temperature within the cata...

Plasma treatment of contaminated water appears to be a promising alternative for the oxidation of aqueous organic pollutants. This study examines the kinetic and oxidation mechanisms of methyl tert-butyl ether (MTBE) in a dense medium plasma (DMP) reactor utilizing gas chromatography-mass spectrometry and gas chromatography-thermal conductivity techniques. A rate law is developed for the remova...

Adaptation of network weights using LevenbergMarquardt (LM) training algorithm was proposed as a mechanism to improve the performance of Artificial Neural Networks (ANN) in modeling the Tennessee Eastman (TE) chemical process reactor. A Neural Network of the AutoRegressive, eXternal (NNARX) input model was developed. Four sub-models for the TE reactor were built. They are: the reactor level, th...

An accurate description of the fluid flow and heat transfer within a Pressurized Water Reactor (PWR), for the safety analysis and reactor performance is always desirable. In this paper a mathematical model of the fundamental physical phenomena which are associated to a typical PWR is presented. The mathematical model governs the fluid dynamics in the reactor. Using commercial software CFX, a co...

background: in the current study,the hazard quotient, the hazard index (hi) and spatial variations of fe,mn,cu and cr in drinking water sources of andimesk-shush, khuzestan province, southern iranaquifer were assessed. methods: we compared theconcentrations of aforementioned heavy metals in wells and springs inandimeshk and shush regions. the non-carcinogenic risk assessment of heavy metals was...

This work focused on the degradation of toxic organic compounds such as methyl violet dye (MV) in water, using a combined photocatalysis/low pressure reverse osmosis (LPRO) system. The performance of the hybrid system was investigated in terms of the degradation efficiency of MV, COD and membrane separation of TiO2. The aim of the present study was to design a novel solar reactor and analyze it...

Remote detection of undeclared nuclear reactors remains one of the key goals concerning global nuclear security. To meet this goal the WATCHMAN collaboration has proposed the construction of a water based antineutrino detector, sited 13 to 25 kilometres from a nuclear reactor complex. Antineutrinos from the reactor interact in the water of the detector via an inverse beta decay interaction resu...
