System, apparatuses, and methods for processing feedstock have a decomposing stage for breaking down feedstock into liquid and gaseous products and a condensing stage for condensing gaseous products to a liquid condensate. A mixing stage can also be used to combine gaseous and liquid feedstock portions into a combined liquid feedstock to be fed to the decomposing stage. The decomposing stage can be one or more flux tanks having a field generator for creating an electromagnetic field through the flux tank configured to decompose feedstock inside. The condensing stage can have a catalyst tank, distillation tank, condensing pipes, or a combination thereof. The mixing stage can be a reformer device having pairs of plates, at least some of the plates are capable of rotating to generate a shear force that creates a cavitation effect to combine the gaseous and liquid feedstock portions.

A method of recovering gaseous hydrocarbons from tank headspace includes flowing a hydrocarbon gas composition from headspace of a tank fed by a secondary separator into a compressor to form a compressed mixture. The method includes flowing the compressed mixture into a cooling unit to cool the compressed mixture, to form a cooled composition including liquid hydrocarbons. The method includes recovering the liquid hydrocarbons as a recovered liquid hydrocarbon stream.

A natural gas pretreatment system includes a heat exchanger having a first inlet, a second inlet, a first outlet, and a second outlet. The first inlet receives a first pressurized gas stream having a first input temperature, and the second inlet receives a second pressurized gas stream having a second temperature. The second temperature is higher than the first temperature. The first outlet outputs the first gas stream; upon exiting the heat exchanger, the first gas stream has a first output temperature higher than the first input temperature. The second outlet outputs the second gas stream; upon exiting the heat exchanger, the second gas stream has a second output temperature lower than the second input temperature. The system further includes a pipeline network operable to receive the first pressurized gas stream.

The invention provides a thermal cracking system which comprises a reactor, and a feed module or a solid product discharge module. The feed module transports a feed material from the outside environment to the reactor. While being transported, the feed material is heated by the feed module to become molten and fills up the interior of the feed module, thereby preventing air from entering the reactor. The solid product discharge module transports a solid product from the reactor to the outside environment. One end of the solid product discharge module is connected with the reactor. The other end of the solid product discharge module comprises a first opening interfacing with the outside environment. When the solid product is transported to the outside environment, the opening size of the first opening is selected such that the speed at which the solid product is entering the solid product discharge module form the reactor is equal to or greater than that at which the solid product is leaving the solid product discharge module, through the first opening, and into the outside environment. Benefit of the invention includes a higher production efficiency and enhanced safety for a thermal cracking system at industrial scale.
