Affected by the change of energy prices, the enterprises that use petroleum and coke as raw materials to produce urea and methanol have successively transformed their gas-making systems to burn inferior coal to reduce costs.
These changes more or less to the original system and production process caused a certain impact, these new problems caused by the change of raw materials must be solved, to ensure the production of efficient and stable operation.
In view of the characteristics of large amount of matter and high content of benzene organic matter in gas, the method of removing these substances is studied and the solution is given.granular activated charcoal
In this study, the concentration of benzene, naphthalene and ash in gas before purifying feed-gas compressor was determined by chromatograph, picric acid titration and weighing method respectively. According to the measured values, the experimental flow was designed, and coke column and activated carbon column were made by themselves.coal activated carbon supplier
The isobarisothermal adsorption properties of activated carbon at different temperatures, at different pressures and at different flow rates were determined by using the gas produced in the system as samples.
The adsorption effluent curve of benzene by activated carbon was plotted.
The effects of different temperature on the regeneration performance of activated carbon under static environment, the effects of steam at different temperature on the regeneration performance of activated carbon under dynamic environment and the effects of nitrogen at different temperature on the regeneration performance of activated carbon under dynamic environment were studied.
