Oil and gas refers to a combustible, explosive and poisonous gas mixture that is comprised of various volatile hydrocarbon components letting out through evaporative emission in the process of handling and storage of diversified oil products. If discharged directly, oil gas will not only pollute the environment, but also incur direct economic losses to enterprises, and might pose serious threat to the public security as well. Though oil and gas is combustible, explosive and poisonous, yet it has certain economic value. If recycled in a proper manner, 2-3 yuan will be made from per cubic meter of oil and gas. The investment in the oil and gas recovery equipment will be returned in one to two years. Thus, proper oil and gas recovery will increase an enterprise’s benefits, be critically important for the long-term, safe operation of the enterprise, and have a far-reaching significance for both the society and the environment. Ultra-clean oil and gas recovery technology is a new

Separation of CO from converter gas is an international problem, which is mainly due to the converter gas also contains a large number of N2 and CO2. Because of the close boiling point of N2 and CO, the traditional cryogenic rectification process can not be used to separate CO from converter gas. The adsorption of CO and N2 is low, so the conventional pressure swing adsorption method can not be used for CO separation of converter gas. Based on mature and leading PSA CO technology and the characteristics of converter gas, PIONEER has developed the process of the formation of a unique CO separation technology of converter gas, which can be applied to get over 99% purity of CO product in large capacity from converter gas economically. The enriched CO gas can be used for producing high value-added chemical products. CO is a kind of important raw material with chemical synthesis. It can purify CO from the converter gas to over 99%, which is used for the production of ethylene glyc

Separation of CO from blast furnace gas  is an international problem, which is mainly due to the blast furnace gas also contains a large number of N2 and CO2. Because of the close boiling point of N2 and CO, the traditional cryogenic rectification process cannot be used to separate CO from blast furnace gas. The adsorption of CO and N2 is low, and the adsorption of CO2 is easy to poisoning and deactivation, so the conventional pressure swing adsorption method cannot be used for CO separation of blast furnace gas. PIONEER, on the basis of its mature and  leading PSA technology ,  according to the characteristics of blast furnace gas, developed the process of the formation of a unique CO separation technology of blast furnace gas,  by which blast furnace gas can be used from the low cost of mass separation CO. The enriched CO gas can be used for the following three purposes: 1. To produce high value-added chemical products CO is a kind of important raw material with che

I n the process of steel production , a large number of blast furnace gas, converter gas, coke oven gas, rich in carbon monoxide, hydrogen and methane are valuable components, which are the main secondary energy sources of steel works. 55-60% of H2 is contained in coke oven gas, converter gas and blast furnace gas respectively containing 60% ~ 60% and ~25% CO, so steel exhaust completely can be used as a source of chemical synthesis of CO and H2 needed.   PIONEER, on the basis of its mature and leading PSA technology , according to the characteristics of blast furnace gas, developed the process of the formation of a unique CO separation technology of blast furnace gas, by which blast furnace gas can be used from the low cost of mass separation CO. CO is a kind of important raw material with chemical synthesis. It can purify CO from the converter gas to over 99%, which is used for the production of ethylene glycol, acetic acid, dimethyl carbonate, polycarbonate, TDI, DMF and o

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
