This query relates to problems related to boiling in a crude oil heater. This heater operates intermittently downstream of a crude oil pipeline. The heater uses LP steam, and the crude which feeds a downstream tank (at 1.1 bara) has a bubble point of 85°C at 1 bara. The crude skin temperature is...

Many thanks for post - I take your point about retention time.
However the size of particles, by which I mean the size of the water particles in the separator/holdup drum outlet, is unknown. Any ideas of what to take for this?
A further complication/question - In the licensor (UOP)...
Hello everybody
My question is the following:
We have a merox process for treating naphtha. It has a coalex demister on top of the extractor column to remove caustic from the hydrocarbon stream. Upstream of the column is a naphtha splitter reflux drum and pump. Downstream is storage and export...

The Hydrogen sulphide is 2% by volume. The sour water stripper is a fuel gas stripped unit which was originally to discharge to an incinerator. The current plan is to send to a fired heater instead. Ultimately whether from fired heater or incinerator the gas ends up converted to SOx - my...
Hello everybody
My question relates to using fired heaters to perform incineration tasks:
My current project has a large, 30 MW fired heater burning a lean fuel gas (3000 kg/hr). I have 2 offgas streams that I want to burn along with the fuel gas.
1. Sour water stripper gas, which is...
Naphtha Splitter Reboiler Return Line
This discussion refers to the Naphtha Splitter Column (1 off) and its reboiler (2 off) and the likely option for heating this reboiler. For the fired heater option the reboiler outlet line could potentially be long, approx. 23m from column - this is due to...
