Is it permissible for someone afflicted with chronic flatulence to pray at home, given its persistence and the harm it causes to fellow worshippers in the mosque?

We advise you to be patient and seek treatment for your illness. Your prayer at home is valid and accepted, and you are excused from attending congregational prayers. Mosques must be protected from offensive odors, and whoever has an odor that harms worshippers should not attend the mosque. You will be rewarded for your intention to attend the congregational prayer, and its full reward will be written for you if your illness is what prevented you. You must perform ablution for each prayer after the time for it has begun, and you may pray the obligatory and supererogatory prayers with this ablution even if wind is expelled from you during prayer. Strive in supplication and turn to Allah; perhaps Allah will hasten your recovery.
