Kaifeng Air Separation signed a new contract for a set of air separation equipment with capacity of 40,000 Nm3/h with Xinjiang Tianzhi. According to news from October 8th, Kaifeng Air Separation Group Co., Ltd. entered into a contract with Xinjiang Tianzhi Chenye Chemical Co., Ltd. for a KDON-40000/40000 Nm3/h air separation unit. This signing marks another partnership between Kaifeng Air Separation Group and Xinjiang Tianzhi Chemical. It is understood that the 40,000 Nm3/h air separation unit will be used in the clean-up project in Xinjiang Tianzhi Chemical, which aims to comprehensively utilize calcium carbide furnace gas and waste coke powder to produce 100,000 tons per year of ethylene glycol. This air separation unit is an oxygen production system that utilizes a packed tower, compression within liquid pumps, and a pre-purification stage in its operation. That is, pre-purification is carried out using molecular sieves at room temperature; an air pressurization turbine expander provides the cooling required by the system, air is pressurized and expanded, distillation takes place in twin towers, and compression occurs within liquid pumps ； The entire air separation unit employs DCS system control technology.
During tough times, such projects give confidence to industry professionals
I’m afraid it’s just losing money in order to gain attention~~ Hehe~~
Is the 40,000 Nm3/h air separation unit of Kaifeng Air Separation Group Co., Ltd. an air separation plant with a domestic self-developed fixed-pressure process? The internal compression process should have lower costs compared to the external compression process, generate less noise, and offer a higher safety factor for the air separation tower.
It is estimated that the core driving equipment is still of foreign origin. As for energy consumption, it is likely to be similar to that of external compression, or possibly slightly higher~~
Does anyone know if this air separation unit provides intermittent nitrogen at 4.5 MPa?
Is nitrogen of this specification really that poor? ~~What's wrong? ~~
