Gas Dehydration (Gas Conditioning and Processing

From the packed column the wet glycol drops downward into the bottom of the re boiler. A source of heat circulated through a tube in the lower section of the re boiler maintains the temperature of the glycol solution at approximately 165 C (in the case of DEG) which is just below the boiling and decomposition point of Diethylene Glycol.Many installations use a gas fired heater.

AB-528 Requirements for Reduced Supervision of Power

4.2 Power Plants Using Water-Glycol Mixture Section 2.1(2) of the PER specifies the reduced supervision requirements for remotely located power plants that do not produce steam and use a water-glycol mixture with a minimum of 40% glycol. The reduced supervision permitted allows the owner to suspend general, continuous and overall supervision

Thermal Oil Heater - for High Temperature Process Heating

Water and steam are typically used as heat carriers in heating systems. But at high temperatures, water and steam requires a corresponding high operating pressure. In thermal oil heaters, a special oil (HTF) is used instead and it means that you can achieve operating temperatures up …

Steam has the advantage of being a very inexpensive and efficient heat transfer medium capable of achieving high temperatures at superheated conditions. Oil mixtures are capable of operating at temperatures up to 750°F and water/glycol up to 350°F (under blanket), both eliminate the need for costly high-pressure rated systems.

Ethylene Glycol Heat-Transfer Fluid - Engineering ToolBox

Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C).Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions - such as cars and machines with water cooled engines.

Design Glycol Units for Maximum Efficiency

Glycol Thermal Fluids. Glycol thermal fluids can operate at a higher temperature than glycol-water mixes, or water on its own. However, it is more costly than either. Thermal Oils. Oils offer the highest boiling point and are highly versatile. Glycol-water mixes are generally effective up to about 300°F, whereas oils can be effective up to 800°F.

Dec 27, 2019 · These systems can reach temperatures of 0–750° F when using thermal oil, whereas steam-based systems only operate up to 350° F before operating pressures exceed 425 PSIG. Thermal fluid systems using water-glycol solutions can also reach 32–350° F at somewhat lower pressures than steam, which still offers significantly more flexibility than traditional systems.

A: The specific heat of glycol solutions is lower than that of water. In order to transfer the same amount of heat, the lower heat capacity can be compensated for by increasing the flow rate of the heating plant. To calculate this, divide flow rate by the specific heat of the glycol solution at a given mix percentage and working tempera-ture. Q
