Dear all. As China becomes industrialized, their need of PVC has increased and they are having trouble finding petroleum . So carbide based production of PVC is something thats hot over there. Does anyone knows this process? In what ways does it differ from the usual ethylene+choride - EDC -...

Dear all. Does anyone know how many license technologies exist for producing EDC and VCM? So far I've found vinnolit but surely there must exist more licensors out there

Hi all I got an assignment to do a quick cost estimation of an amine wash system for a petrochemical plant. This system contains a step for raising the pressure over a liquid from 2 -> 10 bara, the liquid flow is about 400 to 1000 gpm. Anyone who knows what such a pump costs and whats its called?

Dear all Im calculating on the cost for an absorption stripping system and Im trying to estimate the installation cost in the case when shell&tubes are used and the one whrn plate heat exchangers are used. The method Im using now is distributive factors on the purchase cost. However Im afraid...

Hi everyone Im looking for engineering costs when dealing with systems such as absorption stripping or evaporization within petrochemical industry Anyone who knows anything interesting?

Dear all. Im simulating a CO2 capture unit for an ethylene plant. What molar % of CO2 is resonable to apply and do you think the absorption unit will differ very much in efficiency and heat if I choose ethylene, ethylene and ethane or something else as flowgas ?

Dear all. I wonder if any of you know where CO2 and/or H2S capture systems are fitted in the petrochemical industy. I found them in the ammonia process and ethylene oxide process. Very often the solvent in the ammonia process is K2CO3. Can it be any amine as well? Anybody with any expiriences...

Hello everyone. Does anyone know where to find operational data of any existing aMDEA and Benfield plant? The data of interest is absorber and stripper temperature, column diameter and heigh and [CO2] and [H2S] Thanks

Hi everyone. Im calculating on a lean/rich interchanger for an gas sweetening system. What is done if a shell&tube with theta=1 (deltaT/deltaTL) and the desired temperature of 100C into the strippingcolumn is not achieved and the only reachable T is about 80C? Is an extra heater placed just...

Hello everyone. Does anyone know where I can find the heat of reaction for the MDEA for gas sweetening? Thank you all

Im doing a MDEA natural gas treating plant in ASPEN with bad results. Anyone who know how the solution to gas ratio and the solution composition should be?
