High-pressure internal deaerator (Stork)

Pressure vessel (yālì ró ng qì), English: pressure vessel refers to a closed device that contains gas or liquid and carries a certain pressure. In order to implement scientific management and safety inspection more effectively, pressure vessels are divided into three categories according to working pressure, medium harmfulness and its role in production in China's Pressure Vessel Safety Supervision Regulations. And for each category of pressure vessels in the design, manufacturing process, as well as inspection items, content and methods to make different provisions. Pressure vessels have implemented the safety and quality licensing system for imported goods, and goods that have not obtained the import safety and quality license are not allowed to be imported. According to the latest TSG21-2016 "Safety and Technical Supervision Regulations for Fixed Pressure Vessels", it should be divided into the first group of media and the second group of media according to the media, and then classified into categories I, II and III according to the pressure and volume. The so-called first, second and third categories of the old capacity regulations are no longer applicable.
A pressure vessel is a closed container that can withstand pressure. The use of pressure vessels is extremely wide, it has an important position and role in many sectors such as industry, civil, military and many other fields of scientific research. Among them, the pressure vessels used in the chemical industry and petrochemical industry are the most, and the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. Pressure vessels are mainly used for heat transfer, mass transfer, reaction and other technological processes in the chemical and petrochemical fields, as well as storage and transportation of pressurized gases or liquefied gases; they are also widely used in other industrial and civil fields, such as air compressors. All kinds of special compressors and auxiliary machines of refrigeration compressors (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.) are pressure vessels.

Product Introduction

Built-in deaerator

Dutch Stock patent technology—holds a unique and leading position in the deaerator sector.

For units exceeding 200 MW, the overall equipment cost is lower than that of conventional head-type deaerators.

The deaerator room’s height has been reduced by 3 to 4 meters, significantly cutting civil engineering costs.

Reduce costs associated with insulation, platforms, piping, and feedwater recirculation pumps.

Reduce steam consumption; exhaust losses are only 1/6 to 1/5 of those of conventional deaerators, thereby lowering operating costs.

Membrane-type deaerator

Product configuration: deaerator head plus water tank; the deaerator head can be either vertical or horizontal, with the vertical type available in single‑head or double‑head versions.

The feedwater inlet of the spiral‑membrane tube is arranged with a uniform cross‑section, resulting in a thin water film, excellent continuity, and high deoxygenation efficiency, with an outlet dissolved oxygen level of ≤7 ppb.

High adaptability: It can achieve deoxygenation under conditions of low‑temperature influent and high‑oxygen‑content influent, provided that a sufficient steam flow is maintained.

The rated load can ensure compliance with effluent dissolved oxygen requirements within the range of 30% to 110%.

Wide range of applicability: 10 t/h to 2,400 t/h, suitable for both fixed- and sliding-pressure operation.
