AI Technical Summary

Problems solved by technology

Additionally, coke deposits can interfere with the flow of the reaction mixture due to the reduced tube cross-sectional area and can lead to higher pressure drops and reduced efficiency
This carbon build-up can eventually lead to forced shutdown of the reactor and loss of production

Embodiment Construction

[0016] The presently disclosed subject matter relates to improved hydrocarbon cracking systems.

[0017] The disclosed subject matter provides a hydrocarbon cracking system for cracking hydrocarbons and includes one or more components through which hydrocarbons flow during cracking. For example and without limitation, one or more components of the hydrocarbon cracking system may include furnace tubes and coils.

[0018] For purposes of illustration and not limitation, Figure 1A with 1B is a view of an exemplary hydrocarbon cracking tube in accordance with the disclosed subject matter. In certain embodiments, a component of hydrocarbon cracker 100 (eg, cracking tubes, also referred to herein as reaction tubes or furnace tubes) has a wall 104 with an inner surface 102 and an outer surface 103, and may have A plurality of depressions 101 , such as depressions or dimples, are present on its inner surface 102 . In certain embodiments, the depressions do not protrude, ie, protr...

Abstract

The presently disclosed subject matter relates to an improved system for hydrocarbon cracking. In a specific non-limiting embodiment, a hydrocarbon cracker system can include one or more furnace tubeshaving a plurality of indentations disposed thereon, where the indentations do not project into the interior of the furnace tube.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to US Provisional Patent Application No. 62 / 190,446, filed July 9, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The subject matter of the present disclosure relates to systems for hydrocarbon cracking. Background technique [0004] Steam and catalytic cracking of hydrocarbons are important processes in the refining and petrochemical industries and are used to produce light olefins such as ethylene, propylene and butadiene from heavier and more complex organic molecules. These light olefins can be used as intermediates to produce other hydrocarbons such as polyethylene. Hydrocarbon cracking involves cracking reactions of hydrocarbon feed streams, such as ethane or naphtha, and can be performed in tubular reactor systems. [0005] Problems in hydrocarbon cracking reactor systems include the accumulation of hydrocarbon ...
