Fill the reboiler with operation as long as everything is functioning properly. It is necessary to periodically ap glycol to the surge Open the cocks on the glycol surge tank level gauge and apj because a certain amount of glycol loss is normal. The skid provided to this specifica- tion is to have a pull bar or lift lugs for loading and A contactor provided with trays shall utilize a min- unloading for shipment.
