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...

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...

The reliability of VPSA oxygen production plant is mainly reflected by factors such as the failure rate of matching components, the rationality of the process design and the maintenance during downstream usage. First of all, high-efficiency & durable adsorbent and reasonable process design. The core of VPSA technology is the adsorption efficiency and performance of the adsorbent. S...

The VPSA plant is a complete set of systems. On the premise that the process design is reasonable, the supporting equipment is properly selected and the operation is smooth, the power consumption of the entire unit will be ensured the lowest. Specifically, related factors are as follows: 1. Whether the adsorbent is efficient. The most efficient adsorbent currently on the market is the PU...

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...

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...

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 ...

There are two ways to provide VPSA enriched oxygen to blast furnace: The First approach is oxygen enrichment after the blower, i.e., the low-pressure oxygen at the outlet of VPSA oxygen plant is pressurized by an oxygen compressor to 6Bar(G), then mixed with ambient air in the cold air pipe at the blast furnace blower outlet to achieve enriched oxygen. The second one is oxygen inject...

The VPSA oxygen plant consists of power system, adsorption system, valve system, instrument control system, electronic control system and supporting public & auxiliary system, which are respectively described as follows: The power system, consisting of Roots blower, Roots vacuum pump, electric motor, air filter, silencer, elastic joint and other ancillary parts, works to provide the po...

Due to its low cost, flexible load adjustment, and simple start-up & shut-down, VPSA oxygen generation technology is widely used in industrial production. For example, in the steel industry whose market has improved in the past two years, in order to increase the oxygen enrichment rate of blast furnace, reduce the coke ratio and improve blast furnace production capacity, usually VPSA...
