9 Claims

1. A process for treating aged oil by electron beam irradiation, comprising the following steps:

step 1: homogenizing the aged oil and then feeding the aged oil into a distributor;

step 2: forming a liquid layer having a certain thickness on the distributor;

step 3: installing and debugging an electron beam irradiation device on the distributor;

step 4: installing and debugging a phased-array microwave emitter on the distributor after installing and debugging the electron beam irradiation device;

step 5: turning on the electron beam irradiation device, wherein debugging contents comprise: an aged oil flow velocity, an electron beam energy value, a beam intensity, and an irradiation dosage range;

step 6: turning on the phased-array microwave emitter, wherein debugging contents comprise: a phased-array microwave power density, a phased-array microwave frequency, and a phased-array microwave irradiation angle; and

step 7: dividing the treated aged oil by a divider and then allowing the aged oil after dividing to enter an oil pool and a water pool for standing, wherein oil flows out from an upper layer of the oil pool, a lower layer of the oil pool flows back to an aged oil storage pool, water flows out from a lower layer of the water pool, and an upper layer of the water pool flows back to the aged oil storage pool; detecting the water content of the oil flowing out from the oil pool, discharging the oil from the system if the water content is qualified; or if the water content is unqualified, repeating the step 5 and step 6, and adjusting the divider at the same time until the water content of the oil flowing out from the oil pool is qualified.
