Two-stage Reciprocating Gas Recovery System

BVR-M 2 (Modular)

The TESCORP "BVR-MODULAR 2" Series is a completely self-contained compression system for applications for stock tank vapor recovery, flare gas recovery, or small flow, medium pressure process gas applications. Constructed as a compact and fully-contained system, it is constructed with a Blackmer air-cooled, two-stage, pressure-lubricated, reciprocating gas compressor and TESCORP vapor recovery unit technology and components. The BVR-MODULAR 2 Vapor Recovery Unit is designed and constructed for simplicity of installation and ease of operation for the critical demands of the harsh oilfield environment.

The unit offers the following design and optional features:

Two-stage reciprocating compressor with:

  • Two-stage, single-acting, air-cooled pressure lubricated power-frame compressor
  • Single distance piece and seal assembly
  • Corrosive gas trim
