Low temperature paraffin phase change emulsions ...
A paraffin/water emulsion is a colloid system in which fine paraffin droplets are dispersed in water by a surfactant depicted in Fig. 1. Paraffins are one of the typical organic PCM groups and cover a wide phase changing temperature range of 0–130 °C (Mehling and Cabeza, 2008). In this study three paraffins RT6, RT10 and RT20 provided by Rubitherm Technologies GmbH were used for …sp.infoCited by 67 Publish Year 2010 Author Li Huang, Christian Doetsch, Clemens Pollerberg Paraffin wax–water nanoemulsion A superior thermal energy ...The experiments revealed that the energy stored per unit time per unit heat exchanger volume was the highest for paraffin wax–water emulsion containing 10% paraffin wax, exceeding those of water and pure paraffin wax by 11% and 23% respectively.

This is due to economy, because the heat exchanger tubes can be made to withstand higher pressures than the shell of the heat exchanger for a much lower cost. The support plates shown on Figure 1 also act as baffles to direct the flow of fluid within the shell back and forth across the tubes.sp.info Repair of Exchanger tubes according to ASME PCC-2The Pop-A-Plug&image below system is a mechanical tube plug to seal leaking or degraded high-pressure heat exchanger tubes.
