PSA/VPSA



PIONEER has successfully ensured energy-efficient and large-scale VPSA-O2 plants to provide O2 product at a lower cost. PIONEER's PSA-CO and PSA-H2 technology reached the advanced level in the world.

Based on the high-efficient lithium-based VPSA-O2 adsorbent PU-8, combining with the unique airflow distribution technology, advanced process design and reliable supplementary devices, PIONEER has successfully ensured energy-efficient and large-scale VPSA-O2 plants to provide O2 product at a lower cost. 

PIONEER has built up over 100 sets of VPSA-O2 plants and taken the lion share in the field of VPSA-O2 in China. The VPSA-O2 technology won the first prize for Science and Technology Progress by the Ministry of Education.

PIONEER originates the high and low consumption PSA-CO technology based on PU-1 adsorbent, achieving the efficient separation of CO from nitrogen, methane and other components, which is of great importance for the carbonyl synthesis industry. This technology won the Second Prize for National Technology Invention. 

PIONEEER has designed and constructed dozens of PSA-CO plants for the clients, and becomes the highest shares holder in market with the features including low cost of gas product, high purity, high yield, flexibility of feed gas, moderate operating conditions and easy load regulation , which brings much economic earning and market competitiveness to the user.

PIONEER’s Rapid PSA-H2 technology can purify H2 from shift gas, coke oven gas, semiwater gas, methanol purge gas, methanol pyrolysis gas, ammonia pyrolysis gas, formaldehyde exhaust, refinery reformed gas, refinery FCC dry gas and refined gas.

Supporting Devices of 200,000 t/y Glycol Project of Tongliao GEM Chemical Co., Ltd.

Image
The 200,000 t/y glycol project of Tongliao GEM is the first new-type coal chemical project of China that produces glycol by the brown coal. It is a high-tech project promoted by the government and has been put into operation in 2010. PIONEER provides the 22,000Nm3/h CO device of  PSA purification , 42,000Nm3/h H2device of PSA purification and 20,000Nm3/h VPSA-O2 device to the project. These three sets of large-scale PSA devices have been stably operating since the start and indexes of the product gas meet the design requirement. It provides the 200,000 t/y glycol project of Tongliao GEM with stable and low-cost gas source to create favorable economic benefits to the customer.

PSA Oxygen Technology

Image
PSA oxygen technology  is one of the air separating technology for oxygen booming in recent ten years. Compared with traditional cryogenic technology, PSA oxygen technology is known for its low investment, low consumption, low operation-maintenance fee, mild process conditions, simple process flow, high automation, high operation flexibility, short construction duration, and safe performance. Up to now, PSA oxygen technology can replace cryogenic in many circumstances, and the PSA oxygen technology is more economic than cryogenic in running. The main components of air are nitrogen and oxygen, so oxygen can be generated through a selective adsorbent which can separate oxygen from nitrogen in a suitable operation condition. In a pressurized condition, when air flows through adsorption beds with zeolites, nitrogen will be largely adsorbed, while little oxygen will be adsorbed, thus oxygen get enriched. When adsorbent is close to saturation, air will be stopped feeding into the bed,

PHOSPHORUS OFF-GAS PURIFICATION

Image
The content of CO in the yellow phosphorus tail gas  reaches up to 90%. Yellow phosphorus tails gas belongs to the ore smelting tail gas whose components are complicated and impurities are various. The existence of phosphorus and sulfur in the tail gas utilization may corrode the equipment and shorten the life of the catalyst, so the utilization rate is quite low. The yellow phosphorus resource is abundant in China and deposit reaches 800-1000 thousand tons, which weighs 80% in the world. In absence of the efficiency and advanced purification technique and utilization mode, the yellow phosphorus plant only burns little tail gas to dry the raw material or for the boiler combustion but most of the tail gas is discharged, thus greatly wasting the resource, intensifying the environmental pollution and obstructing the energy saving and emission reduction. Besides, the resource utilization of C1 chemical products requires deep purification of the impurity in the raw gas, but impuriti
