Assessing Safety in Distillation Column Using Dynamic Simulation and Failure Mode and Effect Analysis (FMEA)

Security Application of Failure Mode and Effect Analysis (FMEA)

Increasingly complex systems lead to an interweaving of security, safety, availability and reliability concerns. Most dependability analysis techniques do not include security aspects. In order to include security, a holistic risk model for systems is needed. In our novel approach, the basic failure cause, failure mode and failure effect model known from FMEA is used as a template for a vulnera...

Failure Mode and Effects Analysis Using Data Envelopment Analysis

Simulation and Control of an Aromatic Distillation Column

In general, the objective of distillation control is to maintain the desired products quality. In this paper, the performances of different one point control strategies for an aromatic distillation column have been compared through dynamic simulation. These methods are: a) Composition control using measured composition directly. This method sufferes from large sampling delay of measuring de...

Hydrodynamics of Sieve Tray Distillation Column Using CFD Simulation

Sieve trays are widely used in the gas- liquid contactors such as distillation and absorption towers. In this article, a three-dimensional, two phase CFD model using Euler-Euler framework was developed to simulate a distillation tower with two sieve trays. Hydrodynamic simulation of air and water system in different rates of gas phase was carried out and velocity distribution parameters, clear ...

Preventive Methods in Logistics Poka-yoke and Failure Mode and Effect Analysis (fmea)

Preventive methods are seldom used in logistics, although there is increasing awareness of their potential. This paper presents two examples of preventive methods currently in use, Poka-Yoke and FMEA (Failure Mode and Effect Analysis). The implementation of Poka-Yoke, the mistake proofing methodology, has been shown to drastically reduce the enormous warranty costs, including logistics costs, w...
