Place heat sensors outside natural gas tubes. Any paraffin deposits will serve as an insulator between natural gas and equipment, decreasing heat transfer.
Wet the equipment surfaces that will be in contact with natural gas with sulfur trioxide, then wash with less concentrated, sulfur trioxide-containing fluid. This renders the surfaces "water-wettable," making it more difficult for hydrocarbons to adhere to equipment.
Add an aqueous hydroxyl-containing solution to the natural gas stream, in an amount sufficient to inhibit paraffin deposits. Preferably, the hydroxyl concentration is between 0.0025 moles per liter and 2.5 moles per liter.
Check heat sensors to verify that there has been no decrease in heat transfer and that you have successfully blocked paraffin deposits.
Obtain molecular sieves with pore sizes appropriate for the hydrocarbons (paraffins) that you are filtering out. Size 5A molecular sieves will adsorb the majority of paraffins.
Place sieves inide the natural gas tubing.
Regenerate the adsorptive power of the sieves, should they become clogged. Heat the sieve and purge it with gas. Replace the sieves, allowing them to further filter gas, until they stop becoming clogged. You have successfully purged your natural gas of paraffins.
