The invention relates to an oxygen-rich blast management system before a catalytic cracking machine. The management system comprises a skid-mounted device and an oxygen / air mixing device, an air inletof the skid-mounted device is connected with an air outlet of the oxygen / air mixing device; a gas outlet of the skid-mounted device is connected with the reactor; air and oxygen-rich gas flow are introduced into an air inlet of the oxygen / air mixing device; the oxygen / air mixing device is used for mixing oxygen-rich gas flow and air with the pressure of 4 kPa, so that the pressure intensity of the mixed gas is lower than a pressure intensity compression threshold value, and the mixed gas is input into the skid-mounted device. The skid-mounted device is used for adjusting the gas concentrationof the oxygen / air mixing device, wherein the adjusted gas concentration of the mixed gas is 26%. According to the management system, oxygen is injected behind the compressor, an oxygen generation device does not need to be additionally arranged, the cost is reduced, low-pressure mixed gas is adopted, and the safety during gas transmission of the gas pipeline is improved.
Description
technical field [0001] The invention relates to the field of oxygen-enriched blast management, in particular to an oxygen-enriched blast management system in front of a catalytic cracker. Background technique [0002] Catalyst burning regeneration of catalytic cracking unit is to compress the air to about 0.3MPa through the air compressor and send it to the regenerator for burning reaction, and then transport the burned and regenerated catalyst to the reactor for catalytic reaction, which is an important second step in the oil refining industry. Secondary processing methods have created huge economic and social benefits. As the demand for oil products continues to increase, it is constrained by the bottleneck of the air supply capacity of the main fan. If enriched oxygen is added to the main fan to increase the processing capacity or operating severity of the device. At present, the oxygen-enriched combustion experiments of catalytic cracking regeneration all use high-conc...
