LPG receiving station project
Thread Content
In LPG receiving station projects, low-temperature propane is brought into atmospheric-pressure cryogenic tanks at the dock, and after heating it is transferred to pressure spheres or loaded onto vehicles. Heating can be achieved using seawater tanks or hot water heat exchangers; in this scheme, hot water heat exchangers are used to heat the -45-degree propane, with the hot water flowing through the tube side. Is this approach feasible? Should the issue of water freezing and causing blockages be taken into consideration?
The pressure of the hot water, the temperature at the inlet, and also the flow velocity within the pipe network. The issue of water freezing has been taken into account.
The loading system is equipped with seawater tank heating and hot water heat exchanger heating; these two features ensure that low-temperature propane liquid will not experience freezing issues.
