[vc_section][vc_row][vc_column][vc_column_text]Prior to unloading rail tank cars filled with liquids that have become frozen or non-flowable, they must first go through a reheating process to bring the liquids back up to their respective pour temperature.\u00a0 Typically, higher viscosity products are transported in insulated rail tank cars equipment with internal heating coils embedded between the inner shell and the outer jacket of the car.\u00a0 These tank car are then hooked up to steam or hot oil generation systems at the unloaded terminal in order to heat the liquids back up.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column offset=”vc_col-lg-offset-1 vc_col-lg-10 vc_col-md-offset-1 vc_col-md-10 vc_col-xs-12″][vc_column_text]<\/p>\n

[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section][vc_row][vc_column][vc_column_text]The challenge with rail tanks cars is that because the heating source is located on the bottom outer circumference of the tank, it takes longer to heat the liquids in the center of the tank.\u00a0 In order to compensate for this, many operators and unloading teams will increase the heating temperature of the steam\/oil beyond the desired target flow temperature.\u00a0 The downside of this strategy is that liquid products can be unnecessarily burned, scalded or discolored.\u00a0 Additionally, higher steam\/oil temperatures increase energy use.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column offset=”vc_col-lg-offset-1 vc_col-lg-10 vc_col-md-offset-1 vc_col-md-10″][vc_column_text]<\/p>\n

[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section][vc_row][vc_column][vc_column_text]The basic Pulsair rail tank car mixing process can operate solely on compressed or gas providing a safe and effective method for accelerating the heating process of the liquids in the car without inserting anything into the car or requiring the use electricity out in the yard.\u00a0 Pulsair can provide rail car adapters to hook the air lines to the car or the system can be integrated into unloading arms, custom unloading assemblies or unloading elbows.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column offset=”vc_col-lg-offset-1 vc_col-lg-10 vc_col-md-offset-1 vc_col-md-10 vc_col-xs-12″][vc_column_text]\"rail[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section][vc_row][vc_column][vc_column_text]<\/p>\n
