Process heat medium TEG heater skid package showing in-line hot oil pumps. Process heat medium pumps and heater control panel inside TEG heat medium heater package at a natural gas processing plant. High temperature process TEG heat medium heater package with 3 heaters for critical service backup. Dual heater packages are piped to allow heaters to operate individually, in parallel, or in series, as preferred by the process plant operators. TEG heat medium skid packages are fully assembled to minimize field costs. All piping and circulating pumps are fully assembled, requiring only connection to the plant process heat medium piping, fuel gas supply, and electrical services. Description: Combustion air intake louvers in TEG system are generously sized to ensure adequate combustion air for efficient burner operation. Triethylene (TEG) glycol/water or ethylene glycol/water heat medium systems require gas blanketing on the complete system to prevent internal boiling within the heat medium heater coils. TEG process heat medium heaters showing phase 1 heater package and phase 2 heater package at a northern British Columbia hydrocarbon processing site.
