Application analysis of HAZOP at gasification furnace in the system of coal to methanol
To master the process and equipment risk involved in gasifier of the corporate methanol workshop gasfication section,the article used the method of hazard and operability study to analyse,obtained in some situation such as high temperature in combustion,low temperature in combustion,surface of high temperature,high pressure in combustion chamber,low pressure in combustion chamber,high different pressure between the gas of export and combustion chamber,high liquid level and low liquid level.there may be reasons and consequences,and puts the recommendation measures to improve the operational reliability of the gasifier,aiming at safety production to the corporate.
Leveraging grid computing technology, i.e. the visualization of distributed computing and data resources such as processing, network bandwidth and storage capacity to create a single system image, we present a Grid Air Quality Forecast System (G-AQFS). The modeling system consists of meteorological and dispersion models coupled in cascade. The computational workflow of the modeling system is defined by means of DAGs (direct acyclic graph). A simple system is presented to manage and schedule the computational grid resources. As case study the system has been applied over Salento area, in the Apulia region (South-eastern Italy), to simulate ground level ozone concentration. Model predictions have been compared with field measurements, with reasonable results.
