In the areas where the atmospheric temperature is below the freezing point, conventional design of chemical injection packages does not work. The injection system has to be provided with a heating system to prevent the chemical from freezing. This can be achieved by electric heat tracing and insulation of the complete system.
Heat tracing is used to replenish the heat that is lost to atmosphere by running an electrical heating element in physical contact along the storage tank, pipe, fittings, valves and instruments. The storage tank and pipe are covered with thermal insulation to minimize the heat loss from it.
Petronash has a whole host of unique, in-house capabilities for engineering, designing, manufacturing and installing these types of packages.
