The acetylene recovery and concentration technology developed by ZYUC. was successfully applied in the second phase of Dongyuan Chemical BDO project in November 2022, and the acetylene tail gas recovery and concentration were successfully achieved. The acetylene content in the recovered tail gas and the concentration of analytically recovered acetylene were higher than the expected indicators. During the actual operation, the operating flexibility of the device is broader than expected, the operation is more convenient, and the safety is also highly guaranteed。
As the world's first successful acetylene recovery and concentration unit, its demonstration is quite outstanding. As an energetic chemical gas, acetylene has considerable economic benefits; Acetylene has active performance and high energy content, so the safety of the device is very important. Therefore, a set of safe, reliable and feasible recovery technologies and process units are needed to ensure the realization of the whole process of acetylene recovery, concentration and resolution, which is very important and quite difficult. Sichuan Zhongyuan United Chemical Co., Ltd. has invested a lot of manpower and financial resources to develop this set of solvent acetylene concentration process. The relevant equipment and process have applied for national patents and passed the HAZOP analysis at one time. The operation is reliable and convenient. Selective absorption and resolution of acetylene; The closed circulation of absorbent and the water balance of the system realize self-balancing and intrinsically safe operation.
In order to collect the first-hand device operation data, ZYUC also established a professional technical service team to provide all-round guidance on the installation, commissioning and operation of the entire device. From the result, the device is quite flexible and can be customized and adjusted according to the tail gas indicators of different BDO users, such as the difference of different components of tail gas and the difference of tail gas treatment capacity. After the smooth acceptance and operation of the whole BDO device, the user successfully extinguished the device torch. This means that ZYUC Acetylene Recovery and Concentration Technology has made an indelible contribution to the BDO industry's safety, environmental protection, energy conservation and consumption reduction, and has set a benchmark for the BDO industry's environmental protection and emission standards and device energy conservation.
At present, more BDO users have come to ask for technical exchange and cooperation. ZYUC has a long way to go and looks forward to providing more power to promote the technical progress of BDO industry!
