Gentlemen, I installed ASPEN exchanger design and rating recently. Currently, I’m trying to be familiar with it by simulating the existing exchanger in the plant I work for. I developed a simulation model for shell and tube heat exchanger based on the available data sheet. When I run the...

Thanks Montemayor for your reply,the liquid is hydrcarbon mostly ethane, propane and normal butane. The ice forms on the outside of the pipe. We assume that the hydrate forms on the internal side of the pipe since the level of the boot increases and the level control valve opens fully...

Thanks europipe and DRWeig, the valve is two phase valve not flash valve, is the two phase valve considered as flash? i took a sample and i simulated the sample composition and it showed that the hydrate forms downstream LCV. I think the heat tracing is short term solution but what about long...

We have drain boot connected to the gas headers upstream the dehydration plant. The liquid from the drain boot is sent to the Blow down system while the vapor is recycled back to the gas headers. The pressure on the gas headers is around 400 psig and the temperature is between 100 to 120 F. The...

I agreed with you that the column is running on stripping mode. However, I need an evaluation what the impact on the column effciency is.

Yes, it is refluxed column. Currently, the reflux drum is not running and the overhead moves through jumper line to another plant.

Hi, What is the impact on the process side if we operate de-ethanizer column as stripper column.

Hi, I would like to do a performance test on three phase separator to test the effciency of the system. I am working in gas compression plant where the three phase separator separates gas, oily water from gas condensate. Please I need help to draft procedures to do the test.

Gent, last month, we installed two pumps on the outlet of the pressure sewer drum. The function of pumps to pump the hydrocarbon that entrained from our feed gas to treatment plants where gas, oil and water are separated from each other. If the level of the drum reaches certain point, the pump...

Thanks for your reply. The facilite that I worked in is NGL recovery unit. However, in the past it was called as LPG recovery unit. I am confused and I need more clarfication about the difference between them.

Good Day, Currentlly, I am working in Gas Compression train faciltie and we are producing C3+. Is our product classified as LPG, NGL or LNG? and what is the difference between them?

Gent, I am working in LPG facility, we are running our flare system which is steam assisted system. I have a concern because always operation operates the steam that provides the smokeless capacity over the requirement flow. Does this affect the smokeless efficiency because I read through the...

Hi, In my Plant we are suffering from fouling in stripper reboilers' tube bundles. I was advised to conduct reboiler decontamination in specified interval to minimize the fouling. Please I would like from experienced engineer to advise me on this issue and what are the benefits gained form...

Dear, if turbine trips, Is there a chance for fuel gas ingress due to stop/ratio valve is not fully closed. To best of my knowledge if that happens there is a possibility of explosion.Also, I would like to know what the safety procedures we should take if the turbine trips to eliminate the...
