The core of the hydrogen peroxide coalescer is liquid-liquid coalescence separation, which achieves efficient removal of trace water or organic phases in the hydrogen peroxide system through three steps of "coalescence filter capture small droplet coalescence gravity/interception separation". It is commonly used in production scenarios such as oil-water separation of residual liquids and purificat

Chemical Equipment is a general term for machines and equipment used in chemical industry production. In chemical production, in order to process raw materials into finished products of a certain specification, a series of chemical processes such as raw material pretreatment, chemical reaction, and separation and purification of reaction products are often required.
Tube and shell heat exchangers belong to inter wall heat exchange equipment, which rely on the heat exchange tube wall to achieve heat transfer between the tube side and the shell side fluids; The core features are sturdy structure, strong pressure and temperature resistance, wide adaptability to working conditions, and customizable on a large scale. It is divided into three mainstream structures:
Horizontal carbon steel storage tanks are mostly atmospheric/low-pressure vessels, which can be arranged on the ground or underground; Bare tanks are suitable for oil products and neutral media, and can be expanded to store weakly corrosive materials after being lined with anti-corrosion layers. They are widely used in the following industries:
The stainless steel tower with outer coil tube belongs to a vertical tower with heat exchange jacket load. The selection of supports is determined based on the tower height, height to diameter ratio, total weight, wind and seismic loads, and the space of the outer coil tube insulation layer. It is divided into the following four categories: high and large distillation absorption towers prioritize
The vast majority of energy consumption in the deodorization section is steam, followed by cooling water/refrigeration power consumption, conveying pump power consumption, and equipment heat dissipation loss
The medium carrying solid impurities (such as sediment, metal oxide scale, welding slag, crystalline particles, fiber suspension, etc.) into the carbon steel spiral plate heat exchanger channel can bring a series of risks such as wear, blockage, corrosion, structural deformation, and heat transfer failure. According to GB/T 28712 "Spiral Plate Heat Exchanger" and relevant specifications for pressu
1、 Structural characteristics 1. Vertical cylindrical structure, with an elliptical/butterfly shaped head on the upper part and optional butterfly or conical heads on the lower part; Leg or skirt support, making full use of vertical space, occupying a small area, and facilitating the centralized arrangement of multiple units in the tank area.
