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.
Stainless steel tower belongs to pressure vessel mass transfer equipment, which is divided into distillation tower, absorption tower, desorption tower, extraction tower, washing tower, etc. It relies on gas-liquid/liquid-liquid mass and heat transfer to complete separation, absorption, purification, and gas purification; Select 304, 316L, duplex stainless steel, corrosion-resistant, hygienic and n
1、 Basic Definition Horizontal carbon steel storage tanks belong to atmospheric and low-pressure static equipment. The cylinder is horizontally arranged and made of carbon steel (mainly Q245R and Q345R). They are mainly used for storing liquid media (oil products, chemical raw materials, sewage, solvents, etc.), and the design pressure is mostly atmospheric or slightly internal pressure (ge
1、 Core functional role 1. Heating, cooling, and correct temperature control of materials inside the tower (most importantly) Steam, thermal oil, and hot water (heating) are introduced into the coil; Cooling water and frozen salt water (cooling) transfer heat to internal materials through coils → tower walls, achieving heating, cooling, and constant temperature maintenance, adapting to exo
Coil reaction vessels are divided into two categories: Built in coil (immersion coil inside the kettle) Outer half tube coil (welded semi-circular tube on the outside of the cylinder, commonly known as outer coil) Core function: Introduce steam, thermal oil, cooling water, and frozen salt water to achieve heating/cooling, replacing traditional jacketed reactors.
1、 Split of maintenance cost composition The maintenance of stainless steel towers is divided into two parts: maintenance of the tower body and maintenance of the tower internals (packing, nozzles, defoggers, supports)
1、 Petroleum and refined oil storage and transportation (the most core application in the oil and gas industry) 1. Crude oil storage tank area Large external floating roof vertical carbon steel storage tanks are used for crude oil receiving, transit, and strategic reserves in refineries, oil depots, and ports.
