    Quantity of Sulpher in gas

    If you can get your volumetric flow rate (Q ), then Quantity of S collected = Q (m^3/day) x 0.497mg/m^3 in mg/day. If you do not have your volumetric flow rate, try to get the pressure, temperature and molecular weight of your gas. density of your gas = (Pressure x Molecular weight)/ (Gas...

    Crygonic Draining

    cryogenic liquid? Do you mean liquid such as LNG, Liquid N2... These liquid can be easily vaporized before you can collect them, depend on your cold insulation specification. Heat leak into the drain pipe can heat it up. It is not easy to freeze those liquid to freezing point. Once they are in...

    Glycol injection for hydrate prevention

    I think tickle is suggesting you to get a copy of GPSA book. Inside this book, you will find method to estimate MEG requirement. You calculate the minimum inhibitor concentration required in your water phase based on Hammerschmidt's equation, then you size your dosing rate based on your...

    Pressure drop through an adsorber

    skuntz, Page 17 in the presentation showed you a curve that i mean to you : pressure drop per lenght of bed vs superficial velocity. Thanks, Laliyo.

    WATER COOLED HEAT EXCHANGER TEMPERATURE LIMITATIONS

    Jason is right, check you water quality. The film temperature at your water side maybe higher than you think, and caused fouling to your heat exchanger.

    how to consider tolerance in process design

    i think measuring temperature range 45.0 to 55.0 deg C should be no problem for most temperature sensor, either thermocouple, RTD, ... To be sure, you can consult instrument engineer or ask your supplier. You can download instrument specification from website to check their measurement...

    Gas treatment unit design

    HYSYS Amine Package can do the simulation quite easily if you use DEA. BRE have this PROMAX to do better simulation based on the operation experience. Depend on which software you have.

    how to consider tolerance in process design

    depend on your process parameter setting as well. If you need to measure up to one decimal point, you can specify it in your instrument data sheet that measurement accuracy up to 0.1 decimal point, and let the instrument supplier to the recommendation, or you can go to their website to find out...

    Pressure drop through an adsorber

    Gas Conditioning & Processing - Campbell or you can refer to GPSA - chapter 20 - dehydration. If you know the supplier of dessicant that you are going to buy, suggest to get the curve of pressure drop/length vs gas flux across packed bed from them, it will be more accurate.

    Pressure drop through an adsorber

    you can find the equation in Campbell reference book as well.
