CO2 capture from gas turbine exhaust is a possibility for emission reduction on oil and production platforms. A standard process based absorption in monoethanol amine (MEA). challenge that the cost of size weight equipment higher than land-based process. into (MEA) simulated Aspen HYSYSTM. The was obtained In-plant Cost EstimatorTM. base case assumptions which are earlier works assumed to be cl...

Ethanol is a renewable resource of energy and is potentially cleaner alternative to fossil fuels. Production of ethanol is growing day by day at a great extent for its versatile application and demand. During recent years, production of ethanol by fermentation on a large scale has been of considerable interest to meet to increased demand. Fermentation is a biological process in which sugars suc...

The HP scrubber is an equipment used to separate liquid from gas in the oil and industry. low level vessel one of abnormal conditions scrubber, a blowby event will happen because level. So, controller indicator required prevent system damage workplace accidents. alarm response time calculated order avoid accident. To determine for dynamic process simulation method can be using Aspen HYSYS versi...

This paper presents a neural network based strategy for the modelling and optimisation of distillation columns incorporating the second law of thermodynamics. Real time optimisation of distillation columns based on mechanistic models is often infeasible due to the effort in model development and the large computation effort associated with mechanistic model computation. This issue can be addres...

A gradient free optimization-simulationmethod for processesmodelledwith the simulator AspenHYSYS is developed. The tool is based on a Tabu Search (TS) and the Nelder-Mead Downhill Simplex (NMDS) method. The local optima that result from the TS are fine-tuned with NMDS to reduce the required number of simulations. The tool has been applied to find the total refrigerant flow rate, composition and...
