A laminar path distillation device receives gaseous and/or liquid condensate material from a condenser. The liquid material exits through a bottom-side portal while the gaseous material is further cooled by way of a chilled coil. Some, all, or substantially all of the gaseous material which enters the laminar path distillation device passes there-through in a laminar manner until exiting via an exit portal into an apparatus housing a cold trap. As such, the laminar path of the gas is pulled through via a vacuum and also, in embodiments of the disclosed technology, extends on a diagonal slant downwards through the laminar path distillation device or cow.

A device for recovery of an atmosphere containing solvent vapours from at least one ink recovery reservoir of a print machine comprising: n (n>1) filter(s) arranged downstream from the at least one ink recovery reservoir, each filter: comprising an inlet face, an outlet face and a filter body between these two faces, and each of the filter being upstream from a condenser or other solvent extraction structure, an atmosphere output from the at least one ink recovery reservoir passing through a separator and through the inlet face, and then through the filter body and through the outlet face before being sent to the solvent extraction structure, the device further comprising at least one second reservoir to recover liquid from the separator.

Methods and systems for recovering alkenes (e.g. ethylene, propylene) from process gas streams, including multi-step condensing of the process gas stream, are provided herein.

Methods and systems for recovering nitrogen and alkenes (e.g. ethylene, propylene) from process gas streams, including multi-step condensing of the process gas stream, are provided herein.

Examples of a flexible pyrolysis system are provided that include at least one reaction chamber capable of pyrolyzing a combination of coal in a supercritical carbon dioxide (CO.sub.2) atmosphere. The system includes a recuperating and condensing circuit that removes dissolved pyrolysis products from the supercritical CO.sub.2 atmosphere and then recovers CO.sub.2 for reuse in the reaction chamber. The recuperating and condensing circuit includes multiple stages of recuperators and collectors that can be independently controlled in order to selectively fractionate the pyrolysis products. In addition, the pyrolysis reaction may be controlled to alter the pyrolysis products generated.

Systems and methods for recovering light hydrocarbons from refinery waste gas using a back-end turboexpander to generate a higher recovery of the light hydrocarbons for use as petrochemical feedstock and to remove the liquid light hydrocarbons before entering the turboexpander.

The present disclosure is related to systems and methods for the biological processing of hydrocarbon-containing substances. In particular embodiments, the systems and methods herein relate to pre-digestion of hydrocarbon containing substances and further processing of the same to produce hydrocarbon fuels, fertilizer, and other products.

Production equipment and methods which reduce gray or off-specification production and improve central processing facility (CPF) efficiency. The process is a combination of unit operations (heat exchange, pumping, and separation) to produce an on-spec gas product, an on-spec condensate product, and/or on-spec oil product. It does so by placing the feed under pressure and heating it to the point that it can be vaporized and separated. The blended components are modulated dependent upon the composition of the produced fluids, produced gas, and off-specification fluid to efficiently produce on-specification products.
