Keeping Natural Gas Liquid (NGL) pipeline components operating in optimal condition is an ongoing challenge for the oil and gas industry. Rising temperatures in the liquid pumps and the resulting issues for their seals represent one such challenge.

This article addresses the normal and excessive leakage rates of mechanical seals in main pipeline pumps that transport Natural Gas Liquids such as ethane, propane, butane and various mixtures of these liquids.

The development of renewable energy sources is being driven forward worldwide. Next to wind, solar, geothermal and hydroelectric energy, marine energy is emerging as an increasingly important renewable energy source. This process entails generating energy from marine currents with compact turbine systems.
