Respected Mr.Sean, Good morning.!!How are you Sir!!!First of all sincere thanks for keen intrest in my problem. I have tried to Answers to your questions as follows :- 1.Actually, I don't have PT ,PC on extractor.It is dynamic type extractor with extraction vessel.I mean one is Spent Acid...

Hello..!! Guys.. I extract Organic e.g.Nitrobenzene,Benzene etc. from Dilute Spent Acid i.e.75 % Concentration H2SO4 approx. remaining water,HNO2 Etc. with the use of solvent Benzene at ambient around 28-30 C.Extraction Vessel Temperature is 40 C having Chilled water Jacket for better...

Dear all experts..!!! I have 11 MT/hr 500 C,90 barg Steam.That is converted into 30 Barg 240 C Steam.This is done by Pressure Reduction Control Valves (Pressure Controllers ) & By BFW injection that is by Temperature Controller(TC).I would like to convert energy in to Electricity Generation...

Respected Sir, Yes,it is exothermic reaction.Heat is removed through water that is produced during reaction.Direct cooling method.When we clean through Water wash it usually observed sodium,Calcium ppm.These might be through Nitrobenzene.Not sure.Other chances is that due to some byproduct...

Dear Mr.KRB.... If I have 13 MT /hr 90 barg Steam and I want to produce from 90 barg to 30 barg than what will be the Investment cost & Savings for installations of backpressure turbine ? I think the chart that is given in your suggested website is useful but to convert 90 barg to 30 barg i...

All are requested to debate lively. Thanks and Hoping cooperation from all members.

Thanks for your reply. We have tried with increasing the inlet Solvent to Water feed ratio.Also we have tried with diffrent Interphase leveles i.e.by keeping higher Interphase levels in both extractor.But eventhough Emulsion at interphase observed in 1st stage.That means there is some time no...

Hello..!!!!Guys..!!!! How are you ? Liquid Phase Hydrogenation with pd/pt based Catalyst Slurry Circulation technology for production of Aniline from Nitrobenzene.Over a period of time Aniline Plug Flow reactor with around 30 no. of trays got high pressure drop this might be due to Aniline Tar...

Now I elaborate about my Liquid Liquid Extraction System as per Below ---I thanks for your reply in Engineering Tips Forum. Sir, I have two stage Liquid Liquid Extraction System.Basic function of the Extractor is to extract Aniline from waste water with the use of Nitrobenzene. The waste...

Let us discuss !!!come on. I request to all of you!!!!

Dear Freinds I have gone through the Kirk Othmers book.But I would like to know about the design calculations of Static Mixture type Extractor(Horizontal Extractor with Internal static mixture which is driven by velocity of fluids produced by pump).Where I would also like to know about the...

Dear Zoobie , Yes I have sludge Build up frequently in Washers Separators.Like every two/three months.The sludge contains mainly FeSo4 rusts ,CaCo3 .Yes You right because We have Process Water with 92-100 ppm Total Hardness and I use dilute Batch of Caustic Soda (From 48 % to 13 % ) .I recive...

Dear All , Good Morning !!! What are the impurities in the Sodium Hydroxide (NaOH)--(Caustic Soda )?Actually,On Commercial Basis---- Physical Appearance,Caustic NaOH % is checked ? Pl. be enlighten on any other impurities ,Sludge that can affect the Washers Separators function of...

Dear All Freinds/Experts.. Hello!!!Everybody, I have two Stage Extractor.Which has Internal Baffles,Static Mixture.Both Stage has two Comartments Organic Side and Water side.The Main function of the Extractor is to extract the Organic with the use of Solvent from the Waste Water. Basically,I...

Dear Mr.SSHep I would like to know more about the case study that has happened in your previous indsutry ? Thanks in Advance !!!
