Single-stage Reciprocating Gas Recovery System

BVR-M 1 (Modular)

The TESCORP "BVR-MODULAR 1" 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. Created as a compact and fully-contained system, it is constructed with a Blackmer air-cooled, single-stage, pressure lubricated, reciprocating gas compressor and TESCORP vapor recovery unit technology and components. The BVR-MODULAR 1 Vapor Recovery Unit is designed for applications in field gas or refinery process applications where very saturated and/or corrosive gases must be processed.

The unit offers the following design and optional features:

Single-stage reciprocating compressor with:

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