Growing demand and higher prices for natural gas might seem like good news for Asia’s largest oil & gas company. But for giant, Sinopec -- the world’s fifth largest company -- significant gas price increases in China also impact the cost of its own gas processing operations. That’s why engineers from the Sinopec Nanjing Engineering Company (SNEC) sought innovative technologies that could reduce energy consumption in the amine gas treating process at the state-owned company’s Songnan Natural Gas Plant in northeast China.
The Innovation Solution
Amine gas treating is an energy-intensive process for removing H2S and CO2 from natural gas. In the process, these compounds are absorbed at a low temperature and high pressure, and then released at a high temperature and low pressure. Sinopec looked to Energy Recovery for a way to transform the plant’s pressure cycles into reusable energy, while also minimizing the wasted energy associated with operating two high pressure pumps in parallel. By implementing Energy Recovery’s IsoBoost System (known as the Turbo GT in this installation), which consists of a turbine and pump rolled into one, the IsoBoost solution allows Sinopec to harness energy from its high pressure flow, retain its fully redundant system, and lower Its operating costs- all at once.
