The invention relates to the technical field of pure water production and treatment, in particular to high-purity pure water production and treatment equipment, and aims to solve the problems that existing pure water production equipment is poor in pretreatment effect, filtering efficiency and service life are difficult to balance, and impurities are inconvenient to collect. The equipment comprises a pretreatment box, a raw water tank, a filter tank, a reverse osmosis unit, a pure water tank and a deep desalter. Water storage, primary filtration and refiltration assemblies are arranged in the pretreatment box, multi-stage filtration of water is achieved by pushing a top plate, a filter plate, a filter cylinder and other structures, an electric push rod drives a transmission mechanism, the filter cylinder automatically rotates and bristles automatically clean, a waste box is stably connected with the pretreatment box through a positioning groove and a positioning column, replacement is convenient, and impurity leakage can be avoided. The equipment is high in filtering efficiency and long in service life, impurities are convenient to collect and treat, and reliable high-purity pure water can be provided for various fields.

A method and assembly for improving and maintaining a seal between an insulating rod and a flange in a desalter entrance bushing assembly. The assembly includes an insulating rod with a shoulder for a biasing component, a hub nut with a spring seat for a biasing component, a biasing component, and a flange to which the insulating rod can create a fluid tight seal. The shoulder and spring seat can form approximately 90-degree platforms on which the biasing component can apply force when the hub nut is appropriately secured to the flange. The method includes threading the hub nut containing the biasing component into the flange. The nut is secured to a predetermined torque and the biasing component ensures that the seal is maintained during temperature and pressure fluctuations.

This application relates to a desalter configuration integrated with a steam cracker. The disclosure of this application provides a method for producing light olefins. In one embodiment, the method includes pressurizing a hydrocarbon feed in one or more pumps to produce a pressurized hydrocarbon feed and heating the pressurized hydrocarbon feed in one or more heat exchangers to produce a heated hydrocarbon feed. The method includes mixing the heated hydrocarbon feed with water and separating the interstage hydrocarbon feed from the interstage water. The method includes mixing the interstage hydrocarbon feed with water and separating the desalted hydrocarbon feed from the outlet water. The method includes pyrolyzing the desalted hydrocarbon feed in a steam cracker.
