Thank you BigInch. These rail tank cars are used all the time. Although we try to give preference to like for like, the previous shipment may have been gasoline or diesel, as well as Jet. When they return to us, they are steamed (cleaning and degassing), and I think it is the steaming which...
Our refinery ships out Jet Fuel by rail tank car. We had in recent times a shipment which was rejected by the customer, as it contained some solid material (rust). I have checked though all stages of loading, etc, and find that the Jet Fuel here is loaded to standard CS rail tank cars, which...
Hi S4in,
You first to determine the reason you need to do this work, and to identify the specifications for the product. The target may be a vapor pressure spec for storage, or for pipeline (or other transport). The process you use will be determined by the overall picture, including but not...
Hello Petro0707. More questions I am afraid, but no answer yet. Have you looked at ther delta T, or hydrogen concentration, to see if you have anything else unusual happening, or catalyst activity changing? How about the pressure taps? Are the readings genuine? Have you verified the results? Has...
I am taking a guess, based on previous experience. Some refiner down the pipeline (if it is indeed pipeline product)is dumping some cracked product to his crude, and getting export value for this material. My guess it that this is a Visbreaker Residue stream (or something similar) being blended...
I can't help with "Hout", but in the FSU (Former Soviet Union) "M-100" is the nomenclature for the most common brand of Fuel Oil. It is often bought by refiners in the West as Soviet refineries frequently have poor separation between the cuts, so M-100 often contains a significant portion of gas...
We run a refinery which receives its crude down a pipeline owned and metered by a third party using Corilis meters, which are the contractual custody transfer point. This crude is extremely waxy, which means that pour point depressants and heating is used down the line. We have noticed when...
This is a difficult one to solve, with in my opinion too many unknowns to get an accurate answer, such as the outside temperature and wind effects, plus parameters from the tank design and operation, such as tank design (round, spherical, conical bottom, etc) any mixing in the tank (direction of...
Guys, interesting exchange about RVP abs vs gauge. Thanks for the clarifications. Let me follow this through and change the thread a little (if you allow me please) and seek advice for what you would do with this associated gas, now that the crude is stabilised. Our oilfields are in a remote...
Please allow me to "piggy-back" onto this thread. We are installing a custody transfer facility in a line with varying water cut from 3 to 30% water, with avg 20%, but there should be no gas. There is a straight 3 kms upstream, so I anticipate the flow to be stratified. Mass metering will be...
Let me add a little to the previous good responses. In our refinery we run the following simple philosophy for the use of fuel to our furnaces and steam boiler house. First we burn fuel gas to the maximum, as we cannot export it, and if we did not burn the FG, we would have to flare it, which is...
Hello Pan,
I would think that so long as the external pipework is in place, that you should have no problem with this conversion, with no modification. Particularly, VGO should need no blanketing. However before you go forward let me list the things I think you need to look at before you can...
We run a vacuum tower with steam ejectors, and send the sour water directly to offsites for purification. We have heard that elsewhere refiners run this sour water to their desalters. Any comments please? Are there any particular problems with this? We are nervous about doing this due to phenol...
This is maybe a little off the thread, but here in Kazakhstan, we have been contacted by a local company who claim to be able to perform cracking of VGO and Fuel Oil by a combination of low temperature thermal cracking together with a massive input of acoustic energy. They claim the order of 70%...
We run 100% Kazakh Kumkol crude, which is extremely paraffinic. Crude Pour Point varies between plus 3 and plus 20 Deg C, with a density range of about 0.87-0.92. Our crude tower bottoms Pour Point is approx 36-40 Deg C, with cut point approx 350 Deg C. The LVGO PP runs approx 38 Deg C, and HVGO...
