The paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. Some mathematical vector models were obtained for control system multicriterion quality indices with due ...

Introduction Applications of multiphase technology are prevalent in petroleum refining, synthesis gas conversion to fuels and chemicals, bulk commodity chemicals, specialty chemicals, conversion of undesired by-products to recyclable products, manufacture of polymers, biotechnology and pollution abatement. In these processes the reactor performance is crucial: it determines the number and size ...

for more than three decades, oxidative coupling of methane (ocm) process has been comprehensively investigated as an attractive alternative for the commercially available ethylene production technologies such as ethane and naphtha cracking. developing a suitable catalyst and proper reactor feeding policy, reviewing and deploying the efficient methods in the separation and purification of the un...

A continuous flow parallel reactor system has been developed to provide a rapid and seamless transition from the discovery phase and production phase of chemical synthesis, particularly in low volume-high value pharmaceuticals production. Using a single fixed bed catalytic meso reactor, reactions can be screened on a small discovery scale over short time scales. The intensified process produces...

Research was conducted to evaluate the feasibility of producing methane gas from combined segregated municipal and agricultural waste. The combination of the two wastes resulted in sufficient nutrient value and bacterial diversity to improve the biodegradability of cellulose and increase the efficiency of gas production from the combined wastes. The feedstock included municipal solid waste with...

The urea reactor is one of the most important units in the urea synthesis process. Rigorous simulation of the urea reactor is necessary and significant. Ho,wever, the complicated thermodynamic system and chemical reactions result in difficulties of modeling and simulation. In this work, the urea reactor is considered as a critical gas-liquid concurrent fluid reactor, in which some perforated pl...

A novel, multimicrocapillary flow reactor (MμCFR) was constructed and applied to a series of sensitized photoadditions involving 2(5H)-furanones. The reactor allowed for rapid and energy-, time-, and space-efficient sensitizer screening, process optimization, validation, scale-up, and library synthesis.

Homodispersed 1.8 nm gold nanoparticles were obtained reproducibly in high yields using the classical Turkevich protocol at a high concentration in a continuous flow capillary reactor. The microfluidic reactor made from commercially available items permitted short mixing, heating and quenching times which are the key parameters of this synthesis.
