New ultra-tight thief hatch reduces storage tank emissions, conserves tank contents

Emerson Automation Solutions has introduced the Enardo ES-665 spring-loaded thief hatch for use on low-pressure storage tanks in oil and gas and other industries.

Storage tanks can emit vapors to the environment, which has resulted in tighter regulations and the need for improved emissions control from storage tank devices. To address this challenge, the ES-665 has been engineered with increased sealing forces, as well as with a tight and consistent fit of the sealing surfaces. The resulting emissions performance of the Enardo ES-665 thief hatch is an industry-leading 0.10 SCFH (standard cubic feet/hour) at 90% of setpoint.
The Enardo ES-665, along with Emerson’s other tight-sealing storage tank solutions, also helps conserve tank contents. The ES-665 provides tank access as well as pressure and vacuum relief to accommodate tank pressure changes that occur under normal conditions. The ES-665 also limits hatch emissions when pressure or vacuum relief is not required.
