Accu/Line™ – Methanol Injection

Precise methanol injection for hydrate prevention and pipeline flow assurance

The Welker Accu/Line™ Methanol Injection System is a turnkey chemical injection system designed to prevent hydrate formation and lower the freeze point in natural gas pipelines. Built for upstream pressure cuts, transmission and distribution pipelines, and onshore or offshore operations, the Accu/Line™ Methanol Injection System delivers continuous proportional-to-flow methanol injection as operating conditions change. With an intuitive touch screen controller, Modbus or Ethernet remote communication, redundant self-priming pumps, automatic failover, audit-trail logging, and optional solar power, the system helps safeguard pipeline integrity, flow efficiency, and uninterrupted natural gas transport.
