Oil tank heating method for CO2 compressor units
Thread Content
Electric heating is commonly used for the oil tanks of CO2 compression units due to its simplicity and convenience; are there any systems that use steam or condensed liquid for heating?
Steam coils or condensate are more commonly used
Electric heating is a good method for heating fuel tanks; it is safe, does not contaminate the fuel, allows easy temperature control, and is simple to install. There’s no need to worry about oil leakage during maintenance and replacement. The downside is that electric heaters are expensive and consume a lot of electricity ； Steam heating can be used, but there is a risk of steam leaks contaminating the oil. Additionally, space is required for the inlet and outlet of the coiled tubes as well as for their placement within the tank, and the welding quality must be carefully controlled. When a problem occurs, it is necessary to stop the vehicle and drain the oil, which causes environmental pollution; moreover, welding work inside the fuel tank is also unsafe. The advantage is that it allows direct use of the excess steam from the production plant, achieving good energy efficiency. Suggestion: For small units or those with a backup supply of steam for heating compressor oil ； For large units, electric heating is used for operation on a single-unit basis.
Of course, electric heating is better as it allows for easy automatic control. Heating with steam or condensate has more relative disadvantages and is always inferior to electric heating.
According to compressor manufacturers, electric heating is generally used more often and is relatively common. As for its advantages, the guy on the 3rd floor provided a comprehensive analysis, and I fully agree.
We have two heating methods here: 1. Steam heating, and 2. Electric heating (it’s the electric heater built into the oil filter unit). During shutdown periods or when starting up for the first time, using electric heating to raise the temperature to around 30 degrees is still beneficial for the equipment!
Electric heating is more convenient and easier to control; here we generally use electric heaters equipped on oil filter machines for circulating heating.
What was said on the second floor is correct; to add something else, using steam or condensate makes it less likely to freeze in winter
