摘要： Disclosed herein are methods for reducing fouling caused by process water present within a water recycling loop of a pyrolysis plant. Fouling is caused by phase separation and accumulation of materials from the process water on equipment surfaces. The method includes applying a total of about 5 ppm to 500 ppm total of a first polymerization inhibitor and second polymerization inhibitor to the process water to form a treated process water, wherein the first polymerization inhibitor has a pygas-water partition coefficient of about 0.0001 to 9 and the second polymerization inhibitor has a pygas-water partition coefficient of about 1000 to 50,000.

摘要： Some embodiments of the present invention provide components for a serpentine fluid reactor which is optimized for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The components are designed by computer modeling the components individually and collectively in which the cross section of flow path is substantially circular under industrial conditions to validate the model design and its operation. Then iteratively the component designs are deformed and the operation of the deformed part(s) is modeled and compared to values obtained with other deformed models until the value of the objective function is optimized (e.g. at an extreme) or the change in the objective function is approaching zero.

摘要： A method (100) for producing hydrocarbons is proposed, in which one or more steam cracking feed streams (a) which predominantly or exclusively contain hydrocarbons with two or more carbon atoms are subjected to one or more steam cracking steps (10), thus obtaining one or more steam cracking discharge streams (b), and wherein one or more reaction feed streams (t, u) which predominantly or exclusively contain methane are subjected to one or more steps (60) for the oxidative coupling of methane, thus obtaining one or more reaction discharge streams (v) which contain ethane, while a separation discharge stream (m) which predominantly or exclusively contains ethane is formed using fluid from the steam cracking discharge stream or streams (b). In the proposed method, it is provided that fluid from the reaction discharge stream or streams (v) is subjected to one or more thermal cracking steps (70) which are subsequent to the step or steps (60) for the oxidative coupling of methane, and in which the ethane which is present in the fluid from the reaction discharge stream or streams (v) is at least partially reacted to form ethylene, under the influence of waste heat from the step or steps (60) for the oxidative coupling of methane, and that fluid (w) from the separation discharge stream (m) is fed into the subsequent thermal cracking step or steps (70), wherein the step or steps (60) for the oxidative coupling of methane and the subsequent thermal cracking step or steps (70) are carried out in a joint reactor and wherein the transfer of heat into the thermal cracking step or steps (70) that follow takes place by convection.

摘要： The present disclosure provides oxidative coupling of methane (OCM) systems for small scale and world scale production of olefins. An OCM system may comprise an OCM subsystem that generates a product stream comprising C2+ compounds and non-C2+ impurities from methane and an oxidizing agent. At least one separations subsystem downstream of, and fluidically coupled to, the OCM subsystem can be used to separate the non-C2+ impurities from the C2+ compounds. A methanation subsystem downstream and fluidically coupled to the OCM subsystem can be used to react H2 with CO and/or CO2 in the non-C2+ impurities to generate methane, which can be recycled to the OCM subsystem. The OCM system can be integrated in a non-OCM system, such as a natural gas liquids system or an existing ethylene cracker.
