Dear Pro
Cyclones have been used successfully to separate dusts and liquid in different kinds of plants It is generally used in a narrowly bounded operating range with very high degree of separation.
I guess it could be better to be chosen the Cyclone and we scrubbing, but
It is required to...
Dear Professional members:
I have a question about the shear-thinning fluid transfer by gravity.
This fluid is with viscosity around 26,000 cp at room temperature, but the viscosity decrease to around 2600 at 50C.
Is it possible to use the tote as discharge tank to transfer this by gravity...
Dear KLEQ
The rupture disc(PSE) often be equipped with relief valve(PSV) if the discharge fluid is viscous or corrosive. It is installed before the PSV intended to block the viscous or corrosive fluid to enter the PSV to increase the PSV downstream back pressure if system overpressure occur...
Dear Moltenmetal, Compositepro, Georgeverghese
Thank you very much for your highly professional suggestions. I assume that 3A, 4A molecule sieve could be used to in this water removal process. The small water molecule could be adsorbed on pore surface, and the larger molecule, such as DCM and...
Dear Moltenmetal and Compositepro
Thank you very much for your insightful suggestions. I am sorry that the process OP is not provided clearly at first time. The mixed organic liquid process condition s OP is at Atm, and OT is around10C.
I tried to find most cost-effectiveness's drying agent...
Dear Professional members :
The dichloromethane, DCM ( CH2Cl2, Methylene chloride) solvent is widely used in the resin plant, since t has high water solubility than other organic solvent, and low boiling point ( b.p is 39.95C at atm). My research is finding a good molecular sieve or active...
Dear eng-tips professional members :
There is the 200kg/hr organic solvent Dichloromethane(DCM), 10kg/hr HCl (90%),40kg/hr Isopropyl chloride(IPC) feeding to the 5m3 Vessel to be produced resin (Operating at 3kg/cm2g and 25C), and 5 kg/hr Nitrogen gas purged at 3kg/cm2g in get rid of water...
Is this unreacted ammonia, referred to as ammonia slip, can be a by-product of certain NOx reduction processes ?
As your process conditions may exist in high dust, high temperature, high NOx and/or high SO2 environments make most analyzer methods of continuously measuring ammonia unreliable...
Water Based Polyurethanes Dispersions(PUDs) are becoming important for the surface coating industry. Besides, PU synthetic process includes acetone process, melt dispersion process, pre-polymer mixing process, and ketimine process.
The flowing method by dispersing PU into water with low cost...
Dear eng-tips members :
Could you please shine me a light how to calculate the heat of vaporization of the Solved-born acrylic resin ? Is it correct to make all the acrylic monomer and solvent ingredient feed into the flash drum in the aspen plus or other simulation tools, and calculated the...
I have some query about aqueous polyurethane production.
It is usually made through three stages, the pre-dispersion, dispersion, and post dispersion, and the phase
inversion process is crucial for producingaqueous polymer dispersion with little or no external surfactants
added. This...
Dear Master Professional members :
I tried to figure out how to use the Aspen plus to find out a simple homework question that is the solubility of PVA(polyvinyl alcohol) in water for several months, but waste a lot of time and no gain.
Could any master please help me to figure out that is any...
I wonder the jet mixer is suitable for your need, cause I saw some jet mixer/pump back design for the storage tank (250 m3) stored the AE3~9 EO or fatty acid chemical which viscosity is less than 200cp, and the pump motor is around 8 kw.
Dear Sir
Excuse me, could anyone please tell me how to where I can find the polymer thermal datebook, such as the solution enthalpy of 1~89% of PVA(polyvinyl alcohol) in water ?
Thank you so much.
Dear Master
Could any professional tell me where I could find the boiling point elevation data, enthalpy, solubility data for the Polyvinyl alcohol polymer water solution since I tried to design one stage evaporator for this PVA recovery ?
Please give me any help and suggestion.
I really...
Dear Sir
It is still hard to fit the following non linear data to get the equation from gnuplot. Could you please share any thought ? Thank you very much.http://files.engineering.com/getfile.aspx?folder=298a1971-5a8f-4df8-8204-b21fb45e9f12&file=2016-11-25_231315.png
Dear Master
Could you please tell me how to transform the following attached pdf x-y graph data to the excel ?
Since I saw someone do this trick and made a Multiple regression equation so that we can plug a variable to
get the answer we want.
Thank you very much for your suggestion and...
Dear member
Could anyone kindly explain to me why the const torque motor is cheaper than const power ? Since the graph attached show that for const torque or const power all fit that formula P*Q=const (P is pressure, Q is pumping rate).
Thank you...
Dear Master members :
I couldn't find out the infrared pyrometer to be installed on the bottom or top of the polyester reactor.
In the past, there may be generated a lot of viscous vapor or liquid contaminated the RTD on the waterborne
resins reactor, and make the cause of the temperature...
