What causes dry gas to contain water?
Thread Content
I would like to ask the experts: what causes dry gas to contain water?
First, it is necessary to understand the principle of the production equipment for \"dry gas\". Dry gas is produced either through the adsorption of moisture from compressed gas by dryers (molecular sieves, silica gel) to dry the gas, or as a by-product of gas separation equipment. The factors causing water carryover are mainly leaks in the cooling systems of the transfer equipment and the poisoning and failure of molecular sieves. For reference.
The water brought for testing had an ethanolamine content of 4.25 g/100L
The criterion is the comparison between the process condition requirements and the actual parameters. There are innate data as well as those that have changed over time. The former is a design issue, while the latter requires analysis and judgment. Generally, the above value may be higher; for reference only.
It is normal for dry gas to contain amine solution. Gas entrainment. It depends on how much is carried. A high-efficiency amine removal separator needs to be added later
When dry gas is mixed with amine solution, first, the separation temperature is high resulting in incomplete separation; second, foaming of the amine solution can lead to entrainment. Alternatively, an efficient centrifuge can be used due to design considerations
