Application of energy storage heat pump system to oilfield waste heat recovery

Presents an application example of energy storage heat pump system in the Xiaermen joint station. The system reconstruction investment is 36.23 million yuan, and the payback period is 3.67 years, saving 4.8 million cubic meters of natural gas and 2391 tons of carbon dioxide emission every year, and the effect of cost reduction and efficiency increase is remarkable. At the same time, the system realizes peak-to-valley shifting with the peak-valley electricity price, which is beneficial to the optimal allocation of electric energy.
