Since the 1.5 million t/y continuous reforming unit of Qingdao Refinery has been transformed into normal production, it has focused its efforts on energy conservation and consumption reduction while maintaining safety production and products. By adopting a series of optimization measures, energy saving has been achieved. The consumption reduction work has achieved good results. Energy consumption has gradually decreased from 181.66 kg standard oil/ton in the initial stage of operation to the current 113.37 kg standard oil/ton, exceeding the design guarantee value of 124.13 kg standard oil/ton, basically meeting the design expectation value of 113.80 kg. Oil/ton.
First, educate employees to increase awareness of energy conservation and consumption reduction. The importance of saving energy and reducing consumption was communicated to employees through various forms such as holding shift meetings and explaining how to save energy and reduce consumption in daily work. Through the above methods, employees’ awareness of energy saving and consumption reduction has been greatly improved. "Energy conservation" gradually changes to "I want to save energy."
Second, optimize production from the process and equipment, and implement the energy saving and consumption reduction work. Gas, 3.5 megapascal steam, electricity, water, etc. are the main factors that affect the energy consumption of the device. In order to reduce energy consumption, continuous reforming devices have taken a major role in these major influencing factors. For example, after solving the problem of large fan vibration, the heat recovery system of the heating furnace was used, and the oxygen content was adjusted to be not more than 5% according to the amount of feed, and the supply of hot air temperature was increased from room temperature to 170°C. It also reduced from 112.57 kg/ton oil at the start of construction to the current 63.625 kg/ton oil; through optimization of steam turbine operation, the intermediate pressure steam consumption of reforming hydrogen recycler K201 was reduced from the initial period of 100 tons/hour to the current 58 tons/year. Hours; For the initial period of operation of the device, the phenomenon of steam running, running, dripping, and leaking is more. The device has ignited more than 40 times and eliminated Xiaobailong completely.
Third, carry out refined management. A “Statistical Account for the Energy Consumption of Reforming Units†was compiled. Each class will record and calculate the consumption of various types of materials, product output, and energy consumption at 6 and 16 o'clock every day, and make comments at the handover meeting. This method promoted a good atmosphere for the energy saving and consumption reduction competition among the teams. Everyone fine-tuned the production operations and made energy consumption indicators repeatedly hit new lows.
