    Can you use steam for cooling?

    A heat pump used for cooling uses electricity to run the compressor that compresses the gas. But is there any technical solution where you instead of electricity use steam as a source of energy for running a heat pump and cooling a medium? I'm very thankfull for any answers!

    Tips on types of cooling towers

    I’m looking for some tips on different kinds of modern cooling tower-type to use for cooling of water used as cooling water in a chemical process plant. The Capacity of the tower should be at least 25MW, cooling for example 2000m3/h from 36 to 25ºC. I would be very thankfull for any tips on the...

    Hydrolysis of ethyl acetate

    Thanks, but I need more help. Let me rephrase the question: What precautions need to be made to avoid loss of ethyl acetate due to acid hydrolysis? I appreciate any help a lot!

    Hydrolysis of ethyl acetate

    Does anyone know under(or have tips of literature) which conditions ethyl acetate will undergo hydrolysis? I’m looking for temperature, concentration and pH intervals in which it won’t undergo hydrolysis since I’m planning to use it as solvent. Thanks for your help!

    Determination of equilibrium line

    Thanks for your reply cawse001 but I’m looking for a procedure for determining the isotherm for a system of organic compounds. I need some hints about how I could set up a test in a laboratory with shakeout tests to determine the isotherm.

    Determination of equilibrium line

    Hi! I would be very thankfull for information about any experimental procedure to determine the equilibrium line (solute mole fraction in extract versus solute mole fraction in raffinate) for liquid-liquid extraction. Thanks! Jonas

    Changing water solublity of ethyl acetat

    Hi! Does anyone know if there is any additive that you can put into an organic solvent to decrease its water solubility? I would like to decrease the solubility of ethyl acetate in water (its solubility is 8g/100ml) without adding any third component to the water phase. Thanks for your help...

    MIBK substitute

    I was woundering if anyone know of good substitute for MIBK (methyl isobutyl keton) as a solvent for extraction of organic compounds. Thanks for your help!

    New liquid-extraction processes?

    Hi! I really need some help to get started on a project I’m working with, I’m kind of stuck and could use a pointer. I’m trying to find a new liquid-extraction process for extraction of organic by-products. I would be very thankful for any tip of new promising upcoming extraction processes, as...
