August 19, Anqing Petrochemical has a recycling of energy-saving projects — acrylonitrile unit acetonitrile - sodium thiocyanate condensate reuse projects have been formally put into use. The project can be annual savings of 1 million tons of fresh water.

the waste heat generated in the production process, waste water, gas etc. and secondary recovery conversion and use of energy-saving work of Anqing Petrochemical is the main direction. In recent years, they have successfully completed the plant dry ash, oil refining dry gas, sulfur and so a number of key recycling projects, not only reduces the cost of business operations, but also brings environmental benefits of clear water and blue sky.

this year, Anqing Petrochemical to continue the eyes inward, continuing to expand the depth and breadth of energy-efficient space for recycling. The first 7 months, the company implemented a total of 26 energy-saving projects, and increased efficiency more than 1,200 yuan.

3 13, invested 18.5 million yuan of Anqing Petrochemical low-temperature thermal energy-saving projects have been formally put into normal operation of the recycling of this year’s energy-saving work of the enterprise a major bright spot. This transformation, so that crude oil distillation, catalytic, coking unit related to a significant reduction in the medium cooling load, some air-cooling outage, saving 170 kwh per hour, while sub-Ⅱ gas tower and the removal of propylene oxide vapor Bottom Heavy reboiler disabled, low-pressure steam per hour can reduce the consumption of about 28.5 tons, refining energy consumption thus reducing the 3.5 kilograms of standard oil 6 tons a year to reduce power consumption, the cost of nearly 2,500 million, then you can recover the full investment.

Currently, they are continuing to strengthen the operation of low-temperature thermal systems oversight and coordination of management, to avoid possible loss of steam venting. The same time, low-temperature thermal systems for the problem of excess heat, and actively looking for a suitable low-temperature heat users to exploit their energy saving potential.

Anqing Petrochemical is located in the Yangtze River, abundant water resources and does not undermine their sense of responsibility to improve the comprehensive utilization of water resources and urgency. In the past, acrylic spinning unit F13 has been using the B-spray water desalination of water, and hot-drawing overflow water is discharged as effluent in vain. This year, the Anqing Petrochemical overflow of water after the heat drawing temperature impurity removal treatment, desalination of water as an alternative to B-class F13 spray of water, not only to meet production requirements, but also reduces the device’s B-desalination of water consumption, while reducing the external waste water the total annual economic benefits of up to 2 million yuan.

They also catalyzed I pot sewage water, Ⅱ wastewater stripping unit condensate, thermal electromagnetic filters of the cooling water recycling use of fresh water per hour can reduce the consumption of more than 10 tons.

1 ~ 7 months, Anqing Petrochemical refining professional integrated commodity rate, energy consumption, the value of quantitative assessment of three key indicators and the indicators of professional acrylic issued to complete the assessment objectives of the headquarters. Recycling of energy-saving has become a way to enhance the market competitiveness of the enterprise a strong starting point.

安庆石化的另一个能源回收投入使用节能工程

8月19日，安庆石化有一个能源回收节能项目—丙烯腈装置乙腈-硫氰酸钠凝重用项目已正式投入使用。该项目可在1万吨淡水每年节省。

废热在生产过程中产生的废水，废气等，二次采油转化和使用节能工作的安庆石化是主要方向。近年来，他们成功地完成了电厂干灰，炼油干气，硫等一批重点回收利用项目，不仅降低了经营成本，而且也带来了碧水蓝天的环境效益。

今年，安庆石化继续眼睛向内，继续扩大对能源的深度和广度，回收有效的空间。前7个月，公司实施了26个节能节水项目，提高效率超过1200元。

3 13，投资1850.00万元的安庆石化低温热节能项目已正式投入正常运行，今年的能源回收节能企业的一大亮点工作。这种转变，使原油蒸馏，催化，焦化装置与一个在中冷负荷大大减少，一些空气冷却停机，节省了每小时170千瓦时，而撒哈拉-Ⅱ气体塔和环氧丙烷蒸汽清除底部重沸器禁用，低压蒸汽，每小时可减少大约28.5万吨，精炼，从而减少能源消耗标准油3.5公斤，每年6吨，以降低功耗消耗近2500万美元，那么你可以恢复全部投资。

目前，他们正在继续加强低温热系统的监督和管理协调行动，以避免可能的损失，蒸汽排气。同时，低温热系统的过热问题，积极为一个合适的低温热用户希望利用它们的节能潜力。

安庆石化位于长江，水力资源丰富，不影响他们的责任感，提高水资源的综合利用和紧迫感。在过去，腈纶纺丝装置单板机已使用B -喷淋水脱盐水和热拉伸溢出的水白白排放污水。今年，安庆石化溢出的水后，绘图作为乙替代类水单板机喷雾，不仅要满足生产要求的温度除杂处理，海水淡化的热量，而且还减少了设备的B -水脱盐消费，同时减少外部废水总量每年多达200万亿元人民币的经济利益。

他们还催化余锅污水，污水汽提装置Ⅱ冷凝水，冷却水，每小时淡水循环利用热电磁过滤器可以减少10吨以上的消费。

1〜7个月，安庆石化炼油专业的综合商品率，能耗，量化评估的三个关键指标，发给总部完成评估目标专业丙烯酸的指标值。回收的节能已成为一种提高企业强大的市场竞争力的起点。
