Heat exchange in crude oil process pipelines
Thread Content
I would like to know about manufacturers available in the market for crude oil pipelines with a DN700 diameter; increasing the temperature of such pipelines by 20°C would allow them to meet the requirements of operations at 50°C A manufacturer with good performance and quality.
Your requirements aren’t clear. Do you want to raise the temperature of the DN700 pipeline from 20 degrees to 50 degrees, or do you want to heat the crude oil inside the pipeline to 50 degrees? If you heat the crude oil to 50 degrees, you need to tell others the flow rate of the crude oil.
The crude oil in the pipeline is heated to 50 degrees, with a flow rate of 1,900 m³
The flow rate is quite high, while the temperature rise is minimal. Shell-and-tube heat exchangers can be used. What about the heat source? --Steam?
1 There are various ways to increase the temperature; what are the users’ ideas? For example, whether in the form of a heating furnace or a heat exchanger, what type of heat source is available on-site, and what pressure drop losses are permissible. 2. There are many manufacturers of heat exchange equipment on the market; it’s necessary to consider the specifications and type of equipment selected. 3. Given the relatively high flow rate, if a single heat exchanger is chosen, its size will be quite large. However, by using multiple heat exchangers in parallel, smaller-sized units can be utilized. All these factors influence the choice of manufacturer.
Yes, the heat source is steam, with a 300mm steam pipeline.
Steam heat exchange is used on-site; long-distance pipelines require the heating of crude oil, so it is necessary to consult manufacturers with relevant experience.
At first glance, if a single heat exchanger is used, a relatively large heat transfer area is required. However, if there’s sufficient space on site, it’s advisable to opt for a group of parallel-connected heat exchangers; this setup also doesn’t impose strict requirements on the equipment
