PAHAL stands for Pratyaksh Hanstantrit Labh.
DBTL stands for Direct Benefits Transfer For LPG Consumers Scheme. PAHAL. DBTL has been introduced to curb the diversion of the subsidized LPG. Under the scheme, Consumers will pay the market price for the domestic cylinder and the subsidy will be transferred directly to their bank account. This removes the incentive to divert the domestic LPG cylinders, which moved in the supply chain at almost half of their real market price.
Regarding Enrolment you can find more details from Ministry of Petroleum. There are two ways for enrolment
Aadhar based - Link you bank account & aadhar Number, LPG id & aadhar Number
