【Q&A Question 015】January 15, 2018: What are the energy-saving and consumption-reducing measures commonly used in the design of hydrogenation units? (1) A thermal high-pressure process flow is employed to reduce the cooling load on the reaction effluent. (2) Two optimized heat exchange schemes to fully recover the heat from high-temperature gas, as well as from the product wax oil and diesel. (3) Three options for pump equipment with reliable operational performance and high efficiency. (4) The four hydrogenation feed pumps and the lean solvent pump are equipped with hydraulic turbines to recover energy. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.
