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.
The core principle of a vertical stainless steel storage tank is gravity storage, sealing and pressure maintenance, safety balance, and stable support. It relies on a vertical cylindrical closed structure to achieve safe storage of medium at normal/low pressure, and cooperates with accessories to complete feeding and discharging, pressure balance, and safety protection.
The core of a coil type reactor relies on internal/external coils to achieve efficient, fast, and accurate temperature control. It is mainly used for chemical reactions that require strong heat release/absorption, rapid temperature rise and fall, and temperature sensitivity. It is widely used in chemical, polymer, petrochemical, pharmaceutical intermediates, and other fields.
The core of daily maintenance for stainless steel towers is to stabilize parameters, check inside and outside, clean frequently, prevent corrosion, and perform regular calibration according to the "patrol week/month quarter year" classification, which can significantly extend the service life and reduce unplanned shutdowns.
The core value of falling film evaporators in the food industry is low-temperature, short-term, and continuous concentration, especially suitable for heat sensitive liquid foods such as fruit juice, dairy products, and syrup, balancing flavor, nutrition, and energy efficiency.
The coalescer is a core separation equipment in the field of environmental protection that is efficient, purely physical, and has zero chemicals. It is used in four major scenarios: deep treatment of oily wastewater, exhaust gas purification, industrial medium recovery, and emergency water treatment. It can separate emulsified oil/trace droplets to ≤ 5ppm, achieve standard emissions, resource reus
Deodorization tower is the core equipment in the refining process of edible oils and fats. Its working principle is based on the physical separation mechanism of steam distillation (stripping)+high temperature and high vacuum. By utilizing the large difference in volatility between small molecule odor substances (aldehydes, ketones, alcohols, free fatty acids, solvent residues, sulfides, etc.) in
