Emerson Climate Technologies introduces vapour recovery units

Hydrocarbon Engineering,

Vilter Manufacturing LLC, a company of the Emerson Climate Technologies business segment of Emerson, has introduced its next generation vapour recovery units (VRUs).

Emerson’s new VRUs are part of a unique vapour recovery process that employs hermetically sealed scroll compressors requiring low oil flows.

Oil is processed through a multi stage, heated, horizontal stabilizer that removes all absorbed hydrocarbons from lubricating oil. Oil is then returned to the compressor as part of the closed loop lubrication system.

By utilizing the stabilizer, the system maximizes throughput while protecting the compressor from low oil viscosity caused by dilution.

The new VRUs come in two applications: the Vilter VRU-44, which can accommodate pressures up to 175 psig, and the VRU-56, for pressures up to 150 psig. Both units feature a remote operations controller, the ROC827. The ROC827 features snap together module racks to accommodate from three to 27 input/output (I/O) and communication modules, allowing it to store date for EPA reporting and provide real time remote monitoring.

Thomas Hoopes, Director, Hydrocarbon Industry at Vilter Manufacturing, commented: ‘Not only dies the Vilter VRU help companies comply with EPA mandates*, thereby avoiding fines, its design helps prevent premature shutdown due to low oil viscosity and excessive carry over, eliminating the potential lost revenue’.

*EPA 40 CFR part 60, subpart 0000 requires the capture and recovery of at least 95% of tank vapours produced in virtually all crude oil and gas production, transmission and distribution.
