Abstract
Systems and methods for treating hydrogen recycle gas in a process for converting biorenewable feedstock into green diesel fuel are provided. Sponge oil is provided. Hydrogen recycle gas produced during the process is contacted with the sponge oil. The sponge oil and hydrogen recycle gas are contacted in a contact drum and propane and other light hydrocarbons from the hydrogen recycle gas are absorbed into the sponge oil producing purified recycle gas and propane-rich sponge oil. The purified recycle gas is recycled into the process and the propane-rich sponge oil is fractionated to recover propane. The sponge oil may be sour sponge oil to also sulfide a deoxygenation catalyst used in the process.
