Abstract:

A method for operating an acetylene hydrogenation unit of a steam cracking system that integrates a fluidized catalytic dehydrogenation (FCDh) effluent from a fluidized catalytic dehydrogenation (FCDh) system may include separating a cracked gas from the steam cracking system into at least a hydrogenation feed comprising at least acetylene, CO, and hydrogen, introducing the FCDh effluent to the separation system, combining the FCDh effluent with the cracked gas upstream of the separation system, or both. The method may include hydrogenating acetylene in the hydrogenation feed. Elevated CO concentration in the hydrogenation feed due to the FCDh effluent may reduce a reaction rate of acetylene hydrogenation. The acetylene hydrogenation unit may operate at an elevated temperature relative to normal operating temperatures when the portion of the FCDh effluent is not integrated, such that a concentration of acetylene in the hydrogenated effluent is less than a threshold acetylene concentration.

Abstract:

A method for operating an integrated system for producing olefins may include contacting a hydrogenation feed with a first hydrogenation catalyst to produce a hydrogenated effluent, the hydrogenation feed including at least a portion of a first process effluent from a first olefin production process and at least a portion of a second process effluent from a second olefin production process. The hydrogenation feed may include at least hydrogen, ethylene, carbon monoxide, acetylene, methyl acetylene, and propadiene, and the first hydrogenation catalyst may be a hydrogenation catalyst having a temperature operating range of at least 40 C. The hydrogenated effluent may include methyl acetylene, propadiene, or both. The method may further include contacting at least a portion of the hydrogenated effluent with a second hydrogenation catalyst, which may cause hydrogenation of at least a portion of the methyl acetylene and propadiene to produce an MAPD hydrogenated effluent.

International Classification:

C07C 7/167
B01J 23/62

Abstract:

A method for operating an acetylene hydrogenation unit in an integrated steam cracking-fluidized catalytic dehydrogenation (FCDh) system may include separating a cracked gas from a steam cracking system and an FCDh effluent from an FCDh system into a hydrogenation feed and an acetylene-depleted stream, the hydrogenation feed comprising at least hydrogen, CO, and acetylene. During normal operating conditions, at least 20% of the CO in the hydrogenation feed is from the cracked gas. The method may include contacting the hydrogenation feed with an acetylene hydrogenation catalyst to hydrogenate at least a portion of the acetylene in the hydrogenation feed to produce a hydrogenated effluent. The steam cracking is operated under conditions that increase CO production such that a concentration of CO in the cracked gas is great enough that when a flowrate of the FCDh effluent is zero, a CO concentration in the hydrogenation feed is at least 100 ppmv.

International Classification:

A61B 18/26

Abstract:

A catheter system for treating a vascular lesion within or adjacent to a vessel wall within a body of a patient includes a single light source that generates light energy, a first light guide and a second light guide, and a multiplexer. The first light guide and the second light guide are each configured to selectively receive light energy from the light source. The multiplexer receives the light energy from the light source in the form of a source beam and selectively directs the light energy from the light source in the form of individual guide beams to each of the first light guide and the second light guide. The multiplexer includes a system of optical valves arranged in a linear sequence within the multiplexer. The system of optical valves includes an individual valve that receives the light energy from the light source.
