Ruizhi Environmental Protection Equipment Co., Ltd. is an environmental protection equipment Co., Ltd. that integrates research and development, production, sales, and after-sales service.
Overview of the process for refining base oil from waste engine oil:
The waste lubricating oil undergoes preliminary filtration, sedimentation, and flocculation to remove some impurities and moisture. Enter the heat exchange device, heat up to remove impurities, enter the atmospheric tower first, control the inlet and outlet temperatures, enter the gasoline and diesel fractionation tower (under vacuum conditions), and separate the gasoline and diesel components in the waste engine oil. The separated material is reheated and enters a thin film evaporator (under high vacuum conditions). The top of the evaporator is fed into a fractionating tower, where the top light oil, SN150 and SN250, is extracted in sections. The heavy components at the bottom of the evaporator are sent to the cooling storage system or the cracking system. After separation, the base oil is sent to the solvent refining process to obtain various pure base oils (mainly 150SN, 250SN). The fractionated base oil is sent to the base oil blending and re refining workshop.
Advantages of process design
Accurate process simulation calculations provide a good guarantee for the separation efficiency and optimization design of the entire process;
Optimization of heat exchange network, resulting in lower system energy consumption; Maximize the heat recovery and utilization of the product. After normal operation, the heat required for heating the raw materials is provided by the product heat exchange.
The use of efficient catalysts provides better product assurance. The non condensable gas is recycled and enters the lava furnace as a heating source. Residual oil can also be used as a heat source and as an asphalt mixture.
Rich thermodynamic data and years of laboratory experimental data accumulation, such as vapor-liquid equilibrium data and corrosion mechanisms of materials; Design and start-up experience with multiple separation engineering experiences (providing start-up guidance and training services);
Equipment advantages
Tower top built-in heat exchange
Adopting a two end heat exchanger, there is a section of heat exchanger above and below the discharge port.
1. For the feed above the discharge port, it is easy to control the temperature of the top material, the size of the reflux, and the temperature of the reflux, without causing supercooling of the reflux liquid.
2. For the feed below the discharge port, it can more effectively utilize heat and transfer it to other equipment that requires heat.
filler
The filler material and other structures inside the tower are all made of 304 material, and the entire tower filler is segmented according to the characteristics of the filler specifications used. Different specifications of fillers are used above and below the feed inlet of the tower body according to the requirements for material separation, to ensure material circulation, separation efficiency, and separation purity.
On top of the top heat exchanger, a section of filler is also installed to ensure the odor of the distilled biodiesel and the vacuum degree.
heater
Except for the starting heater that uses thermal oil for heating, all other material heaters use product heat heating to effectively recycle and utilize product heat. This alone will save most of the energy consumption during the production process and generate most of the company's profits.
Equipment production
Before equipment production:
Before the production of the equipment, according to the requirements of the process design, equipment size, specifications, etc., the operating pressure, large rated pressure, operating temperature, large rated temperature, equipment materials used, and material origin will be uniformly selected, calculated, and set.
During equipment production:
During the production process of the equipment, automated machines are used for welding, rounding, and other processes to ensure the quality of welding and meet the national first-class requirements. Each piece of equipment processed will have procedures such as pressure testing, 24-hour pressure maintaining, and flaw detection. To ensure the quality of the products leaving the factory.
After equipment production:
After the equipment is manufactured, surface treatment should be carried out for special equipment surfaces. Ensure the anti-corrosion and other characteristics of the equipment. During equipment transportation, our company will reinforce and stabilize the equipment to ensure that it will not be damaged during transportation.
Our company will provide lifelong maintenance and repair to the equipment produced by our company. Any technical issues encountered during the production process will be addressed by dedicated personnel. Our company will provide free technical support to customers.
