Emerson storage-tank hatch reduces theft and emissions
Emerson Automatic Solutions has released a spring-loaded hatch to reduce the chance of theft and limit emissions from low-pressure storage tanks in the oil and gas industries. Called Enardo ES-665, Emerson's device has been engineered to accommodate tank pressure changes and limit hatch emissions. ES-665 releases an industry-leading 0.1 SCFH (standard cubic feet/hour) in emissions at 90% of setpoint. The device's lid latches and locks for added security and safety.

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 vapours, 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 helps to 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.

In addition to its ultra-tight emissions performance, the ES-665 includes:

An available center assembly for improved performance of previously installed models.

Multiple relief settings and material options for application flexibility.

A latching and lockable lid for added security and safety.

Based on testing at ambient conditions in accordance with American Petroleum Institute 2000 and competitive published data.
