The high-flash-point vapor recovery project at Sino-New Chemical is in full progress. Author/Source: Sino-New Chemical. Date: 2022-04-20. Clicks: 11. During the operation of the facility, after vaporization, the high-flash-point vapor is stripped, and approximately 1000 kg/Nm3 of combustible non-condensable gas is sent along with saturated water vapor to the flare for combustion, resulting in certain waste. Calculations show that this portion of the stripping gas contains approximately 300–400 Nm3/h of non-condensable gas, with the effective gaseous components accounting for about 60% of it. To completely eliminate the torch while reducing energy losses in the system, and after considering the operating conditions of related units and conducting thorough evaluations, it was decided to send this gas to sulfur recovery for use as a combustion gas in the burners. On the one hand, gas resources are utilized in a rational and effective manner; on the other hand, while reducing the output of fuel gas, the volume of synthesis cycle gas is increased to further optimize the performance and efficiency of the methanol plant. To actively advance the implementation of projects related to the recovery and utilization of high-flash-point materials, the Production Scheduling Center takes the lead, with close cooperation from the Mobile Equipment Department, the Technology R&D Center, and relevant branch factories to form a cohesive effort; responsibilities for various tasks are clearly defined, and the construction progress is advanced in an orderly manner in strict accordance with the established task plans. Stringent control is exercised over the quality of project acceptance to ensure that lines and equipment are installed in accordance with specifications; detailed reports on the progress of work for that day are sent to the high-flash-point gas mitigation coordination group. This approach ensures that there are clear plans, tasks, and goals, with all team members working together to facilitate the smooth implementation of energy-saving renovation projects.
