Description of Services:WRC exclusively conducts waste oil processing at the site using dehydration, distillation and filtration techniques. By permit, it is only allowed to treat/recycle waste oil/bunker sludges (Philippine waste code I101). Oils containing PCBs, glycols, emulsifiers, metals (such as from cutting oils) or solvents are not accepted.

The first step of the process is moving the waste oil from storage to a feed stock tank for the start of processing. Waste oil is initially pre-heated to ~65°C, and then taken through the primary process tank to the main process vessel. The primary process tank operates as an additional pre-heat tank for the incoming waste oil (increasing temperature to ~75°C) and it also recovers heat from the heater exhaust economizer. The waste oil then proceeds from the primary process vessel to the main process vessel where it is heated with heat transfer oil from the heater.

Distillate (or light ends) passes out of the top of the main process vessel through heat exchangers for heat recovery. From there the distillate passes through a bank of condensers and into the dirty distillate tank. This distillate consists at this point of water, and light hydrocarbons. The water is removed and sent to the water treatment system and the light hydrocarbons pass on to the "diesel" tank. The dirty diesel tank is also designated as the heavy condenser accumulator. Depending on the waste oil coming in, some hydrocarbons lighter than diesel are collected in a tank designated as the light condenser accumulator, and are sent to one of the centrifuge purifiers. This product stream is very much like kerosene.

Oil from the bottom of the main process vessel is heavy fuel oil and that is sent via the storage and pre-heat tank (to recover more heat) to the final product tank. From this tank, it is either piped directly to fuel the RCC cement kiln or accumulated in the RCC bulk storage tank in the RCC fuel tank farm. From there, it can also be delivered to the cement kiln or taken by tanker to other RCC cement plants.
