Problems with using liquid nitrogen washing for gas purification?
Thread Content
As the title suggests, in the process flow for producing syngas by purifying the gas obtained from fluidized-bed gasification using liquid nitrogen washing, what is the most appropriate way to handle the gas released after the liquid nitrogen washing?
The analyzed gas is generally sent to the fuel pipeline network as fuel exhaust; if its calorific value is low, some H2 or crude water gas can be added as well
What process technologies are available for recovering this gas to produce syngas? What is the feasibility?
