Hi All, I am trying to size a PSV (PSV172) for a Nitrogen Supply Line to Well Control Panel as per attached file. The PSV is installed on the N2 Supply Line with a set pressure of 1,380 kPag and Vent to Safe Location. I have some information of the Nitrogen Regulator (BOC Regulator 8000)...

Hi Everyone, I am looking for your advice with regard to the calculation I am currently doing to find the remaining life of dehydrator bed. Parameters: Inlet water concentration: 50 PPMV Target Outlet Water concentration: 0 PPMV Inlet Fluid Flow: 30 m3/h Operating Pressure of the vessel...

Dear Engineers I am looking for your advice with regard to the calculation I am currently doing to find the remaining life of dehydrator bed. For example: Inlet water concentration: 50 PPMV Outlet concentration: 0 PPMV Inlet Flow: 30 m3/h Operating Pressure: 16.7 barg Operating Temperature...

Hello Everyone, I am currently working a process to determine the liquid volume and level of level transmitter in a vessel. I am looking for some guidance and advice to perform liquid volume in a vessel and level transmitter calculation. I have two questions below: 1. How can I determine the...

Hello, I need help to checked the size of the vent, flow capacity and fluid properties at reliving conditions for Emergency Vent installed on Waste Water Tank. I am trying to use HYSYS simulation to do this, but it doesn't really work well with the below conditions. How is the best way to...

Hello, I am looking for some good reference to get better understanding in the use of Temperature Control Valve and Pressure Control Valve. I am not really sure how is the function of the TCV and PCV in controlling the flow through a pipe. I want to ask any help from you to give me some...

Hello everyone, A good day to you all. I was thinking if i could be possibly get some guidance from this forum regarding Phyton Script. I hope some who is familiar with this program language can throw some knowledge in to this post. I am trying to build my script to generate a regression...

Hi Engineers, I'm looking for some guidance to verify the required PSV shown in the datasheet is correctly stated. From PSV datsheet: Component = Nitrogen Vapour Required Capacity = 2,013kg/hr Normal Operating Pressure = 8.65barg Set pressure = 12.3barg Over-pressure = 10% Relief Temperature...

Dear Engineers, What are the difference between Flow control valve (FCV) and Pressure control valve (PCV) with respect to their working, design and application in controlling the fluid? I have attached a sketch to show the control system (PCV and FCV in series) to control the fluid before it...

Hello Everyone, Would like to get some idea and guidance to determine the liquid level in distillation column at the bottom tray. 1. What is the practical way to calculate the remain liquid height at the bottom tray of the column? 2. How can i get the pressure losses at the Nozzles (N1 and...

Hi, I would like to get some advise in modelling the Hyraulic HYSYS model to determine the velocity of a fluid through the pipes. I am creating the piping model from Wellhead pipe to the test monifold so that i can know what is the velocity in pipe and to compare to the maximum allowable...

Dear Engineers, I have got one basic question on defining the number of stages in HYSYS simulation for a distillation column. As an example, - on the design datasheet of the column it says that the the number of trays is 22 and the feed enter at tray 10. My question is why when we sepcify...

Dear Friends, I am currently doing a simulation on CO2 removal unit using ProMax program. I have some issues in simulating my stripper column. I have simulated the absorber column, but when it goes to stripper column it's unsolved below is the message I got from ProMax...

Dear members, I am doing a separator sizing check for the separators we have at our plant. I would like to determine the design capacity of the separator and then compare the result to the actual operation to see how far over or under the design capacity. I am still new to this concept so, I...

Dear members, I am looking for document of ISO 6976:1995 for the work i am doing to determine the greenhouse gas emissions. One variable i need to calculate separately is the density of the fuel gas and it's must be determined based on the ISO 6976:1995. Can anyone help me how can i find ISO...

Dear Members, I would like to have some ideas regarding the handling and storage of the foam concentrate for fire fighting. At present, We have the hydrants installed at our facility, we are planning to install a foam IBC (RF3 3%) tank behind the hydrants to supply foam to our hydrants. This...

Dear all I am doing pressure loss calculation using HYSYS. I want to determine the pressure drop in control valve and Flow meters in the piping. I need to know if adding orifice plate in HYSYS simulation is possible or not? And if possible how to add it and what are the parameters needed to...

Hi all, I want to determine the NPSHa for a pump (amine charge pump) with a flow rate of 350 m3/h. I want to do HYSYS simulation to find the some data required for manual calculation. With HYSYS I want to calculate fitting and friction loss, vapour pressure of liquid at pump and velocity at...

Dear friends, I have a question regarding the standard installation (the safe distance) for fire hydrant from the protected area. We have a fire hydrant at our plant locates just around 6 metres from the protected area which is the bunded area (NGL Storage Tank). My question: Is there any...

Hi, I would like to have some ideas about pressure drop calculation for gas (condensate). Does the elevation (the different elevation is 18 m) and the sudden enlargement and contraction affect the pressure losses along the pipe? if it does, how to determine the total pressure drop? Can...
