A reactor and method for the conversion of hydrocarbon gases utilizes a reactor () having a unique feed assembly with an original vortex combustion chamber (), a diverging conduit (), and a cylindrical reactor chamber (). This design creates a compact reaction zone and an inwardly swirling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a diverging conduit (). The feed streams can be introduced into the reactor () at any angle (radial, axial, or something between, or a combination of the above forms) with swirling flow components. The feed streams comprise preheated steam and hydrocarbons for cracking. This system provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.

Method and reactor for conversion of hydrocarbons

The invention is directed to a chemical reactor () having (a) two or more gas reactor elements () with each gas reactor element () having (i) a first reaction chamber (), and (ii) a feed assembly unit (), (b) a second reaction chamber () coupled with each of the two or more gas reactor elements () and configured to independently receive two or more product streams from the two or more gas reactor elements (); and optionally, (c) a gas converging section () located downstream to the second reaction chamber (). The invention is further directed to a method of producing chemical products using the chemical reactor () of the present invention.

Reactor system for the production of high value chemical products

A pyrolysis reactor () and method for the pyrolysis of hydrocarbon gases (e.g., methane) utilizes a pyrolysis reactor () having a unique burner assembly () and pyrolysis feed assembly () that creates an inwardly spiraling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a burner conduit () with a constricted neck portion or nozzle (). At least a portion of the swirling gas mixture forms a thin, annular mixed gas flow layer immediately adjacent to the burner conduit (). A portion of the swirling gas mixture is combusted as the swirling gas mixture passes through the burner conduit () and a portion of combustion products circulates in the burner assembly (). This provides conditions suitable for pyrolysis of hydrocarbons or light alkane gas, such as methane or natural gas.

Reactor for pyrolysis conversion of hydrocarbon gases

A reactor () and method for the conversion of hydrocarbon gases utilizes a reactor () having a unique feed assembly () with an original vortex disk-like inlet flow spaces (), a converging-diverging vortex mixing chamber (), and a cylindrical reactor chamber (). This design creates a small combustion zone and an inwardly swirling fluid flow pattern of the feed gases that passes through a converging conduit () with a constricted neck portion (). This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.

A device for mixing two gas streams, the device includes: an inner pipe, wherein: the inner pipe is arranged substantially concentrically within an outer pipe and forms an annulus between an outer diameter of the inner pipe and an inner diameter of the outside pipe; the inner pipe is closed at a downstream end; and the inner pipe comprises a plurality of perforations; and the outer pipe, wherein: a downstream end of the outer pipe extends into a reactor; the outer pipe is closed at the downstream end; and the downstream end of the outer pipe comprises a plurality of perforations. The mixed gas stream can enter the reactor. The reactor can be an Oxidative Coupling of Methane (OCM) reactor.

Two stage gas-gas mixer

Systems, methods, and devices for predicting pump performance in a downhole tool are provided. A pump performance predictor may receive inputs and generate outputs that predict the performance of a pump of a pumpout module of a downhole tool. The pump performance predictor may calculate and output a set of first predictions that include, for example, the minimum alternator voltage of a power module used to power the electronics of the pumpout module, the maximum pump flowrate, the pumpout performance, and the achievable formation mobility. The pump performance predictor may also calculate and output a set of second predictions that may include, for example, a pump volume efficiency, a pressure profile in a flowline, the number of strokes to fill a sampling bottle, and the time to fill the sampling bottle.
