Product Features

Oil distillation system

1. Technical process instruction

After adequately exchanging heat with the product from lateral line of distillation tower, raw oil enters into furnace and is heated up to the required temperature. The raw oil after heated in furnace is transferred into the distillation tower for distillation, a fter cooling, non-combustible gas can be got at the top of tower, gasoline fraction at the 1^st atmospheric line, and light diesel fraction at 2^nd atmospheric line, heavy diesel fraction at 3^rd line and heavy oil at the bottom of tower. The wax content in raw plastic oil is relatively high; the raw plastic oil enters into fixed bed reactor for catalytic de-waxing process after the heat exchanging through furnace, and then is transferred into the distillation tower for distillation, and each lateral line product will be got. Non-combustible gas is introduced into furnace for burning as a kind of fuel. Gasoline and diesel fractions are continuously transferred into oil blending system for alkali washing refinery and blending to get the dynamic gasoline and diesel which can meet market requirement. The heavy oil at bottom of tower is transferred into heavy fuel oil tank to supply fuel for furnace and steam boiler; the rested heavy oil will be blended according to market requirement and then sold as fuel oil.

2. Equipment Constitution and Main Equipment

The oil distillation unit is totally divided into 8 systems as following: Steam boiler system Raw oil system Every lateral oil line system Non-combustible gas system Cooling water system Compression system Oil blending system Control system

3. Features and advantages

1 . It can realize the continuous process, blending and refinery of raw oil, maximize the process capacity of the complete set of equipment, minimize the production time and optimize the quality of output, in the meantime, production efficiency and enterprise revenue will be improved significantly. 2 . Non-combustible gas is introduced into furnace for burning as a fuel, which not only reduces the emission pollution and also saves energy as well as lowers cost. 3 . Three main advantages of fixed bed reactor: (1). Effectively solve the problem that the impurity content in raw oil is so high that deactivates catalyst quickly. (2). It can realize the catalyst recycling and reduce operating cost greatly. (3). The catalytic de-waxing effect can not only improve the yield rate of gasoline and light diesel with high added-value, also improve oil quality effectively. 4 . The complete set of distillation system is automatically controlled by PLC (Programmable logic control) system, achieves to automatically control the reference points and has multiple functions, such as, data collection, calculation, record, print report forms, alarm and so on.
