An Economic Analysis of VPSA Oxygen Plant(6,000Nm3/h, 100%)for BF Enriched-Oxygen Combustion Supporting in Steel Mills

Vacuum pressure swing adsorption units are used to produce oxygen at purities between 80%-94%. The technical principle is to separate the oxygen in the air utilizing the different selectivity of adsorbents for oxygen and nitrogen. Units using this type of non-cryogenic oxygen production process may be referred to as VPSA (Vacuum Pressure Swing Adsorption), VSA (Vacuum Swing Adsorp...

Applications of Pressure Swing Adsorption Technology in Environmental Protection

Pressure swing adsorption technology is mainly applied to the recycling of industrial tail gas rich in CO. People may not know that China is the world's largest manufacturer of steel, calcium carbide and yellow phosphorus, which accounts for more than half of the world's production. A large amount of industrial exhaust will be released when manufacturing these fundamental industrial products...

Applications of Pressure Swing Adsorption Technology in Chemical Industry

The pressure swing adsorption technology is mainly applied in C1 chemistry in the chemical industry. Does anyone know where objects like daily beverage bottles, sofas, quick-drying T-shirts come from? They were all produced by petroleum cracking and then through other synthesis procedures step by step. As we know China is rich in coal and poor in oil. In resent 20 years, the “coal chemica...

Applications of Pressure Swing Adsorption Technology in Steel & Iron Industry

1. Blast furnace oxygen-rich coal injection. There are two conventional ways for iron & steel smelting. The first is to use the iron ore in blast furnace to smelt the iron of the compound in nature into zero-valent iron, which is the pig iron we often say. The pig iron is then refined through a converter to become a variety of alloy steels or stainless steels that we often see in our daily...

What are the Requirements for Oxygen Plant Valves?

The operating cycle of the VPSA oxygen production process is very short, generally less than 1 min. In one cycle, each adsorption vessel needs to experience the steps of adsorption, pressure reduction, desorption, purging, even pressure increasing, etc. Key valves switch on and off once in each cycle, which is pretty frequent, so they are required to be switched quite fast in order to impro...

How to Maintain the VPSA Oxygen Plant?

VPSA oxygen plant suppliers usually provide overall materials including instructions for use, maintenance manuals and troubleshooting manuals. The structure of VPSA plant is simple- the rotary equipment only consists of a blower and a vacuum pump which are general-duty equipments with simple maintenance, therefore, maintenance of VPSA oxygen plant is generally composed of two parts: i...

Introduction of Power Equipment of Oxygen Plant

The VPSA oxygen generation plant is characterized by its short operating cycle (generally only tens of seconds), so the exhaust pressure of blower will change rapidly with large fluctuation ranges during operation. Based on the principle of vacuum pressure swing adsorption, the blower is required to satisfy the stability of gas volume under the circumstance, which is the essential condition ...
