At present, the more mature electric desalination technologies include: AC desalination and dehydration technology, AC and DC electric desalination and dehydration technology, advection squirrel-cage electric desalination and dehydration technology, heavy oil deep electric desalination and dehydration technology, high-speed electric desalination technology and double-input double electric field electric desalination Dehydration technology, etc.

In the terminal oil and gas recovery system, the ship-to-shore connection system (interface/handover system) is a key system that connects the ship and the oil and gas recovery processing device and ensures the safety of the ship and the terminal facilities. It mainly includes the gas phase arm (hose) and the ship-shore interface safety device installed at the front of the shore station wharf.

Foreign countries have applied advanced control technology to more than 90% of atmospheric and vacuum units, catalytic cracking units, hydrogenation units, etc., and achieved considerable benefits. Nanjing Wellland Energy Technology Co., Ltd. has marketed products including: crude oil blending system, gasoline and diesel blending system, online near-infrared oil property analysis system, rapid evaluation system of all oil properties, and device quality optimization control system.
