Hi, I need information how to set and represent the control logic for positioning of Pressure Control Valve in pump discharge line on P&ID. The pump is pumping a seawater to be processed for well injection. The pump discharge line is an 8" line discharging into a commom header of 20" line in...

Hi, I need information on how to generate the relationship between irregular shape to standard orifice size. I want to use in calculating the flow of fluid through the orifice. I would appreciate urgent responce. Thanks

Hi, I have been studying on the design of a centrifugal compressor. I need information on the control aspects such as the: 1) Capacity control 2) Anti-surge control {am studying that at present) 3) Load sharing (How do one share the load on compressor?) In depth understanding to the above...

Thanks djack for your advice.

FiltrationEngineer, Thanks for your responce. Actually, what i need to design is a WASTEWATER TREATMENT SYSTEM FOR A HOSPITAL. I believe there should be engineering processes that i can use to prepare my design, because am a process design engineer. I will appreciate any information to...

Artisi, The treatmaent is for wastewater from a hospital and process involved.

Hi All, i want to design a sewage treatment plant. The waste is non-toxic water. The following information was given: Volume: 180 m3/day Diatance between the outlet and discharge point is 500m. please, i need information on how to achieve this task. Thanks

Am not. May be you don't understand me. The detail given to me by the client is to design a vessel that will handle a 50K bopd of crude per day. The initial vessel is a rectangular tank, but they want to change it to horizontal vessel. They propose the size i.e. 13'x40' and gives the...

the value given was 13 feet diameter and 40 feet long. All, i wanted to do was to confirm if the dimension given for the vessel is capable to handle the fluid.

The information given to me by the client is that they want to convert a rectangular shaped surge tank to a horizontal vessel capable of handling 5oKbopd with adequate retention time which was given for each level swicthes. The information i need is to determine the diameter and length of the...

Hi guys, I want to size an horizontal Surge Vessel to handle 50,000 bopd. The % height of the LSL, LAL, LAH, LSH has been given. There respective respective retention times required has been given. How can i determine the diameter and length of the vessel? I try using DEP but bit confuse...

Hi, i am developing a conceptual model for gas dehydration using TEG using HYSYS. The regenerator column for the TEG does not converge. I specify the required information by the column, putting the solver into adaptive mode to enhance convergence, and both condenser& reboiler pressure. The...

Montemayor, i think you are the one that do not understand my post. i know that i cant use HYSYS to do mechanical sizing, but it can perform the process simulations that you said. actually, i was working on a model, ion which i tried to study the effect of pressure drop in the hot stream...

Hi guys, how do i use HYSYS to specify a heat exchanger to increase the temperature of a process gas to desired temperature. What is the effect of pressure drop in the hot stream. Regards

another way to achieve the desire result is to create seperate stream for the oil and gas. input the compositions for each stream but at the same temperature and pressure. input the flowrate for the oil and specify a molar flowrate on the gas stream till it gives you the desired gas flowrate in...

thanks morten, i noticed the statement you are pointing at.

Hi Guys, Can you please tell me how to use HYSYS to carry out the following: vessel capacity check on seperator and scrubber,equipment sizing and nozzle sizing. Thanks
