Hi. We are having this very visous (1000 cP) slurry that needs to be pumped. We are using a progressive cavity pump for that. Although the pump vendor knows about this viscosity, and has ensured us that his pump is the right pump, I was wondering how I could calculate the power requirement to...

Hi. Can anyone help me understand what a Petroleum Engineer exactly is? What does he do? I was thinking that it is simply another term for Chemical or Process Engineers... THanks

Hi guys. One of the things we run into often when doing a revamp is the need to recalibrate the instruments; Temperature, Pressure instruments as well as Level instruments. My question is why do we need to calibrate an existing instrument? For example, suppose we are changing the operating...

I was wondering if there are any technical forums related to Polyethylene similar to this forum.. Appreciate.

How can one rate an existing Heat Exchanger using only the T-Q data?? Usually that kind of ratings is done using HTRI.

Hi, are there any guidelines as to where to install the control valve in the steam line to reboiler? should it be installed in the inlet or rather in the condensate outlet line?? Any idea what the pros and cons will be?? Thanks

Hi, Can anyone tell me what exavtly is the "Liquid Hourly Space Velocity"? I think it must be some sort of required velocity in a reactor that is needed for a proper reaction. who can help me with this? I appreciate it.

Guys, Is there anyone familiar with the TEG dehydration process? I know myself how it works, but what I don't know is how such a system is generally simulated? In other words, how is the main TEG contactor where the gas is treated with Lean TEG being sized? And how about the Rich TEG...

Hi guys, Who can tell me how LNG is exactly produced? I know about different gas treatment process, what I don't know much about is how the gas is liquified using turbo expander and the cold boxes. I appreciate it.

Dear Friends, I am now really confused! THis sounds stupid, but.. When specifying a control valve that is in the discharge line of a pump, I use the pump curve to determine the pressure before the vlave (corrected for friction losses). My confusion arises from the fact whether I should also...

Hi all, I have a question regarding separating a high hydrocarbon-alcohol (C9OH) and water mixture. The water concentration is very low, 0.3 wt%. We have in our installation a liquid-liquid separator that works on basis of density difference of these two liquids. But it's not working that...

Hi all, I have a question. I am trying to assess a PSV in the discharge of a centrifugal pump. But it seems difficult to determine the relief load. Here is hte system: A centrifugal pump, some reactors in serial line up, a control valve, a safety valve and a block valve. THe case I am...

Hi For our project in Kuwait, we are considering to allow the liquid blowdown of an incinerator, which consists of mainly spent caustic and some solids, to be sent to drying beds where, after water has been evaporated by solar radiaition, the solids can then be separated. However, in order to...
