I am currently working on a project where I need to determine the wellbore heat input required to prevent paraffin formation in production tubing. In this particular case the production tubing runs to a depth of approximately 3000m and there is a larger heat medium casing surrounding the...

In API 521 (section 5.4.1.3.1) it is mentioned that "In general, laterals and tailpipes from individual devices are sized based on the rated capacity of the device,...". This sounds like laterals and tailpipes are different piping?

I was looking for some information in API 521 and I came across a reference for sizing tailpipes and laterals based on rated flow. I was originally under the impression that laterals and tailpipes were one in the same (single-source piping directly downstream of releiving device). If someone...

Liquid carry over does not appear to be an issue. There are several separators that relieve into this subheader but they are equipped with mist eliminators and I have confirmed that they are sized correctly. A co-worker of mine has suggested that I consider the possibility of vortex formation...

I am tring to determine if a drip leg on a flare subheader has sufficient holdup volume. The flare subheader is 24" NPS and the drip leg is located at the low point on the flare subheader prior to elevating about 2 m in order to tie into the main flare header (upstream of KO drum). Our client...

I am trying to determine what the relieving temperature is for a Blocked Flow PSV on a Fuel Gas Drum. The Operating Pressure is 20 Barg and the PSV set pressure is 25 Barg. I don't expect there to be a large temperature increase but I need an accurate value for the relieving temperature. Is...

I am trying to determine if a set of pumps in a flare radiation zone will be sufficient. The pumps are located at a distance of 100m from the base of the flare stack. According to the radiation isopleths the pumps will be exposed to a radiation of 3 kW/m2 (including solar)during full flaring...
