Optimization Of Texaco Coal Water Slurry Gasification Process

Coal-water slurry is a new kind of fuel developed in recent years.It is a kind of coal-based fluid fuel and has become the national promotion of environmentally friendly products.Coal water slurry is coal,additives,grinding water according to a certain percentage of grinding through the mill,the formation of a certain concentration of fluid fuel,which has a high concentration,uniform particle size distribution,good flow properties,good stability,high conversion rate of environmental protection Energy-saving feat.s.Although coal-water slurry gasification has many merits to be affirmed,there are still many shortcomings in the practice of industrialized production.As a result,the equipment can not be operated safely,steadily,Explore,research,mining its economic benefits.In order to improve the concentration of coal-water slurry,increase the effective gas production of gasifier and reduce the specific oxygen ratio of coal gasifier,and increase the economic benefits of the company,this paper studies coal slurry preparation unit for coal slurry enrichment reform,making coal slurry concentration From the original 58.5%to 62%,and achieved remarkable results.In order to give full play to the production capacity of the downstream equipment,the production problems can be solved by comparing with similar project production equipment.Expansion of gasification unit transformation,so that methanol products and downstream products according to market prices to adjust its output,air separation plant can maximize its potential to improve the overall profitability of the device.After the expansion of the gasification unit,the effective gas production increased from 155,000 Nm3/h before the renovation to 211,000 Nm3/h.The coal consumption and oxygen consumption increased correspondingly,which was lower than the coal consumption and the specific oxygen consumption.Coal-water slurry gasifier operation more problems,it is difficult to meet the long-term operation.Through continuous operation of the experiment,analysis,summary,the production process optimization,the problem gradually be solved.Single furnace operating cycle gradually increased from the previous 50 days to 110 days;burner operating cycle gradually increased from 50 days to 90 days.The long-period operation of the device is realized,the production and operation are convenient,the energy consumption is reduced,the maintenance cost of the device is saved,the cost is maximally saved,and the benefit of the product is improved.
