Project for Utilizing the Residual Pressure of Medium-Pressure Saturated Steam in Shaanxi Coking Company’s Alcohol-Ammonia System Put into Trial Operation. Author/Source: Shaanxi Entrepreneurs Association. Date: 2020-06-29. Clicks: 9. The medium-pressure steam at 3.1MP and 2.7MP generated by the synthesis waste heat boiler and the conversion waste heat boiler in Shaanxi Coking Company’s alcohol-ammonia workshop is reduced in pressure to 0.6MP low-pressure steam through temperature and pressure reduction devices, which is then used by other production units within the company. During this process of temperature and pressure reduction, thermal energy and residual pressure are not fully utilized, representing a significant waste of energy for the company. After communication between the company and Xi’an Shida Energy Co., Ltd., and following on-site inspections by relevant technical personnel from both parties, it was decided to make full use of this energy by employing industrial steam turbines. This project involves modifying the system by using a multi-stage steam turbine with a capacity of 1450–2000 KW. The high-pressure motor with a rated power of 500 KW, which was originally used to drive the No. 3 circulation water pump, is removed; instead, the steam turbine is used to drive the circulation water pump. After doing work, the medium-pressure steam is converted into low-pressure steam at 0.6 MP, which is then integrated into the company’s low-pressure steam network, thereby enabling the comprehensive utilization of the waste heat and pressure associated with the medium-pressure steam. “For this project, we conducted extensive market research and investigations in the initial stage, and ultimately decided to carry it out in partnership with Xi’an Shida Energy Co., Ltd. under a contract energy management model. After 3 months of intensive construction, the project has now entered the trial operation phase, and it is performing well. Meanwhile, according to relevant calculations, the successful operation of this project can save the company over 1 million yuan in electricity costs each year. ”The head of the company’s Mobile Energy Department explained.
