The third section of the shift gas washing tower, a large-scale tower component in the purification unit of Yushen Energy Chemical’s 500,000 tons per year coal-based ethanol project, arrived. Author/Source: Yushen Energy Chemical, Yan’an Petroleum Group. Date: October 30, 2021. Views: 14. On October 29, the third section of the shift gas washing tower arrived at the site. The transformed gas scrubber tower (1401-T-001) is one of the core towers in the purification system. It is a low-temperature device made of 09MnNiDR material, with a diameter of 3.6 meters and a length of 86 meters; its total weight is approximately 580 tons, and it was transported to the site in three sections. As of October 29, there were a total of 78 static units for the purification equipment, of which 76 had been delivered, resulting in a delivery rate of 97%; all 12 towers were delivered as well. The arrival of all 12 towers laid the foundation for completing the equipment installation tasks for the purification system in 2021. Recently, the installation of the refrigeration units in the freezing unit of the ethanol plant under the Yushen coal-based ethanol project was completed. It has been successfully handed over to the piping team, which has now commenced piping construction work. It is understood that this refrigeration unit system consists of 4 skids, including 2 sets of compressor unit skids and evaporative condensers, a system liquid storage tank and economizer skid, as well as an evaporator and suction buffer skid. The entire system is well-designed, compact in layout, and energy-efficient; its energy-saving efficiency can reach over 25% throughout the year. With the completion of the refrigeration unit installation, the installation of the complete set of equipment for the ethanol production facility in the Yushen Ethanol Project has officially entered its final phase, laying a solid foundation for the subsequent piping work as well as for achieving the targets set for the critical periods in autumn and winter. On October 26, the lower section of the shift gas scrubber tower (1401-T-001) for the Yushen coal-based ethanol project was successfully lifted, marking the entry into the final stage of the installation of the towers in the purification unit. It is understood that the total height of the reformer gas scrubber tower is 86.3 meters, with a weight of around 523 tons. The lower section of the tower to be lifted this time is 42 meters high, 3.6 meters in diameter, and weighs approximately 253 tons. The lifting was carried out using an 800-ton crawler crane as the main lifting device, along with a 450-ton crawler crane to assist in lifting the tail end of the tower. To ensure construction quality, the contractor developed a specialized lifting plan for the gas scrubber tower as well as a construction plan for building the tower in sections. With the full participation of all involved parties, the lifting work was completed successfully, laying a solid foundation for subsequent installation and welding tasks.
