Processes and Systems for Removing Deposits from an Integrated Plastic Pyrolysis Vessel and a Steam Cracking Furnace - A simplified explanation of the abstract

This abstract first appeared for US patent application 18405762 titled 'Processes and Systems for Removing Deposits from an Integrated Plastic Pyrolysis Vessel and a Steam Cracking Furnace

The abstract describes a process for removing deposits from a pump-around loop or simply loop, involving isolating a section of the loop within a vessel and introducing an aqueous fluid/oxidant mixture to remove deposits.

• The process involves isolating a section of the loop within a vessel.
• A first conduit is connected to an aqueous fluid/oxidant source at one end of the isolated section.
• A second conduit is connected to the other end of the isolated section within a convection section.
• The aqueous fluid/oxidant mixture is heated as it flows through the isolated section.
• The heated mixture flows through the second conduit into a radiant section of a steam cracking furnace.

Potential Applications: - This process can be used in steam cracking furnaces or heat exchangers to remove deposits and improve efficiency. - It can be applied in various industrial settings where deposits in loops need to be cleaned.

Problems Solved: - Removes deposits from pump-around loops efficiently. - Helps maintain the performance and longevity of equipment.

Benefits: - Improves the overall efficiency of steam cracking furnaces. - Reduces maintenance costs by preventing deposit buildup. - Enhances the operational reliability of industrial equipment.

Commercial Applications: - Industrial maintenance and cleaning services. - Manufacturing industries utilizing steam cracking furnaces or heat exchangers.

Prior Art: Prior research may include methods for cleaning and maintaining industrial equipment, particularly in high-temperature environments.

Frequently Updated Research: Stay informed about advancements in industrial cleaning technologies and equipment maintenance practices.

Questions about the Process: 1. How does the process of isolating a section of the loop contribute to the efficiency of deposit removal? 2. What are the key differences between using an aqueous fluid/oxidant mixture and other cleaning agents in this process?

Original Abstract Submitted

Processes for removing deposits from a pump-around loop or simply loop. The process can include isolating a first and a second end of the loop in fluid communication with a vessel to provide an isolated section. The isolated section can include a first conduit disposed within a convection section of a steam cracking furnace or a heat exchanger that is external to the steam cracking furnace that can include char therein. The first end can be connected to an aqueous fluid/oxidant source. The second end can be connected to a second conduit disposed within the convection section. An aqueous fluid/oxidant mixture can be introduced into the first end that can be heated by flowing through the isolated section. The heated mixture can flow through the second conduit to produce a second heated mixture that can be introduced into a radiant section of the steam cracking furnace.
