Glycol heat tracing is used to protect piping, boilers, pumps and any other equipment at an industrial plant from freezing in extreme temperatures. It utilizes a closed loop circulation system of tubing containing heated glycol on process piping to transfer the heat from the traced lines to the installation on the piping. Glycol tracing is used in winterization processes at oil and gas refineries to prevent freeze damage or to keep process lines at the required temperature.
If a system or equipment is exposed to prolonged freezing temperatures, the result can be costly damages and ineffective processes. Glycol heat tracing ensure freeze protection is in place and that all process and equipment will operate at their optimum peak performance. The problem with glycol tracing is waste. If not properly controlled, you could be wasting thousands of dollars on these systems.
HAT (Heat Actuated Trap) or TV/HAT (Tube Valve Heat Actuated Trap) valves are placed at the end of trace lines to regulate glycol return temperature which helps to provide the correct flow of glycol for optimum use of energy thus eliminating waste.
To control temperatures in glycol heat tracing systems, HAT or TV/HAT valves will maintain the discharge temperature. When glycol temperature exceeds the set-point, the valve will modulate closed. As heat loss occurs and glycol cools to below the set-point, the valve will open to allow warmer glycol to circulate.
Protecting pipelines and equipment from extreme weather conditions is essential for plant operation and performance. Glycol heat tracing is ideal in areas where there is frequent cold weather and ThermOmegaTech’s temperature control valves are essential to manage these systems. Easily installed at the end of trace lines these temperature activated valves automatically sense and regulate glycol temperatures to provide the optimal amount of heat needed for processes and to maintain the correct viscosity of the glycol.
