Process Description of Waste Oil
The process of treatment involves dehydration, distillation and filtration. Details of this process are proprietary information, which is owned by New Zealand Marine Services, Ltd. Who developed the technology over a period of years and has successfully licensed applied it commercially in their country. The plant is designed to handle about 50,000 tonnes of waste oil in, and depending on the amount of water in this waste oil, it produces between 30-35,000 tonnes of processed fuel oil and about 1,000 tonnes of diesel-like hydrocarbon most of which is used to operate the onsite generator and run plant vehicles.
The schematic plant layout above ahows how the plant operates. This layout is referred to in the detailed description below.
Raw waste oils are recieved and stored in the bulk storage tank with capacity of 1.5 million liters. The waste oil is then drawn from this tank as required, and held in a feed stock storage and pre-heat tank.
Oil is then drawn from this feed stock tank and taken through the primary process tank to the process vessel. The primary process tank operates as an additional pre-heat tank for the incoming waste oil and also for recovering heat from the heater exhaust economizer.
The waste oil proceeds from the primary process vessel to the process vessel where it is heated with heat transfer oil from the heater. THis heater has a 2 MW burner.
Distillate (or light ends) passes out of the top of the process vessel through heat exchangers for heat recovery. From there the distillate passes through a bank of condensers and into the dirty distillate tank.
