Abstract: A social networking system includes information identifying a machine (e.g., a robot, a drone, a computer, a thermostat, etc.) and a connection between the machine and an owner of the machine, which is a user of the social networking system capable of authorizing an action by the machine. The owner of the machine associates permissions associated with various actions by the machine, where a permission associated with an action identifies one or more criteria for performing the action. Permissions may specify types of connections between social networking system users and the owner of the machine via the social networking system to allow social networking system users with specific types of connections to the owner of the machine to perform certain actions using the machine. Information describing an action performed by the machine may be communicated to other users of the social networking system via any suitable communication channel.

Abstract: Naphthenic acid corrosivity of hydrocarbon feedstocks is correlated with the chemical composition of naphthenic acids, and especially with a ratio between an alpha fraction and a beta fraction of naphthenic acids. Contemplated plants, configurations, and methods are directed to reducing naphthenic acid corrosivity of hydrocarbon feedstocks by increasing the beta fraction over the alpha fraction.
