Oil cleaning system E575R

Overview
The E575R Transformer Oil Regeneration Plant restores used transformer oil to near-virgin condition using a regenerable adsorbent media. The system delivers Fuller’s Earth treatment benefits without the disposal issues of spent clay by reactivating adsorbent in situ. Available as mobile or stationary (skid or container) units, the E575R is designed for large throughputs and continuous 24-hour operation.

Description of Process
Used oil is strained, heated and filtered before entering banks of adsorption columns. Primary physical parameters are restored in the column stage. Oil leaving the columns passes through a degassification unit and an afterfilter to complete regeneration. Column banks are reactivated in situ (no media removal) — typical reactivation time per bank is ~12 hours. Dual-bank operation enables uninterrupted processing while one bank is reactivated. At final exhaustion the media is reactivated and discarded as dry waste suitable for normal landfill, free of oily waste.

Applications & Configurations

• Available as mobile units or stationary units (skid- or container-mounted)
• Mobile configuration suitable for on-load and off-load transformer processing
• Skid-mounted configuration suited for tank-farm and depot applications

Features

• Open technology design — no sealed “black box” or restricted plant areas
• Royalty-free operation — no ongoing gallonage or reactivation fees
• Full 24-hour processing using dual banks to allow reactivation without shutdown
• On-load and off-load processing with Transformer Oil Level Monitoring System (TOLMS)
• Multi-mode capability — can operate as conventional degassifier and for transformer dry-out
• DBPC anti-oxidant blend back facility
• Customizable controls: fully automatic with PC datalogging, PLC, manual override or mimic panel
• Optional full laboratory package, boiler and onboard generator
• All global power supply options available
