| Texaco coal water slurry gasification technology is one of the most widely used in coal gasification technologies in the world. The Texaco water coal slurry pressurized gasification technology is divided into:quench, semi waste boiler and waste boiler process, quench process is the most widely used in the process. Relatively speaking, the use of waste pot process is less, there are many technical difficulties in the industrial experience with a lack of experience, Shenhua Ningxia coal 250000 tons/year methanol is Ningdong coal chemical industry base in the first start and coal chemical project put into operation, The system is the core of the original order of the gasification plant of Shougang Texaco coal water slurry gasification waste boiler process. The main problem of the Texaco coal water slurry gasification waste boiler process in both methanol plant operation for more than 8 years were analyzed. The reasons of the problems and the technical reform was studied. At the same time, the original design of some unreasonable place is for optimization. To solve the main problems which influence the stability of the device, the changes of the global parameters of the device were analyzed to develop a reasonable strategy, convenient operation. To further improve the Texaco coal water slurry pressurized gasification technology of waste boiler process application in long period, the operating cycle increased by 150% after technological updating. Single furnace operated for 163 days and reached the lead of the same level. The direct economic benefit Produce for the enterprise 1425600 yuan/year. |
