burning torch was once a sign of the petrochemical industry. Since 1996, Beijing Yanshan Petrochemical started the flare gas recovery and utilization projects. By 2004, eight torch in the normal production is completely extinguished and recovers about 100,000 tons per year torch gas, instead of heavy oil as fuel, the annual savings of 100,000 tons of fuel oil, while reducing air pollutant emissions.

the past 10 years, the Beijing Yanshan Petrochemical relying on scientific and technological progress, and working out an energy, “reduction, reuse, recycle” in recycling economy, resource utilization has improved significantly. “15″ end and “95″ initially compared to the added value created per ton of crude oil (at current prices) from 497 yuan to 1101 yuan, an increase of 122%; million in energy output fell 55%, yuan output value of consumption of Water down 72%, yuan output value of COD emissions dropped 76%.

“15″ period, Yanshan Petrochemical refining and chemicals for the main unit conducted a series of technological transformation, in the adjustment of product structure and expand plant capacity at the same time, devices of the economic and technical indicators are more rate increase. Ethylene plant, for example, in 2001, after the completion of the second round of transformation, Yanshan Petrochemical production capacity from 45 million ton / year increased to 71 million ton / year, energy consumption, material consumption were significantly lower, in which the overall energy consumption from 824.65 kilograms of standard oil / ton down to 690 kilograms of standard oil / ton; cracking furnace thermal efficiency is improved by 9 percentage points; cracking gas compressor efficiency increased by 8 percentage points; ethylene yield increased by 0.5% than in the past. With 1.3 million tons / year medium-pressure hydrocracking unit, 70 million ton / year of propane de-asphalting unit, as well as two sets of energy-saving devices such as series of catalytic transformation of the completion in 2005 compared with 2000, high-grade gasoline increased from 46.69% increased to 72.19%; light oil yield from 69.69% to 73.8%; refining the overall energy consumption from 93.39 kilograms of standard oil / ton down to 75 kilograms of standard oil / ton.

2006 years for comprehensive utilization of the ongoing 10 million tons / year of by-product of oil refining system, reformed petroleum coke, Yanshan Petrochemical is supporting the building of petroleum coke as fuel in two 310t / h circulating fluidized bed boiler. The boiler combustion efficiency, fuel, wide adaptability to different fuels can reach 98% -99% of the combustion efficiency. In addition, the Yanshan Petrochemical power boiler will also be integrated chemical system transformation, focuses on building large-scale boilers, was closed for part of the oil-fired boiler, thermal efficiency will be increased to 93%.

Yanshan Petrochemical focus on development and application of high-tech, their production processes to maximize the conversion of waste generated as a resource, turning waste into treasure, of harm into, they are reducing the consumption of natural resources, but also to reduce pollutant emissions, develop new space for development of enterprises.

变成伤害宝成步行燕山石化废弃物的循环经济之路

燃烧火炬曾经是石化业的迹象。自1996年以来，北京燕山石化开始了火炬气回收利用项目。到2004年，8个是正常的生产火炬已完全熄灭，并恢复作为燃料约10万吨，每年火炬气，替代重油，10万吨燃油每年节省，同时减少空气污染物排放量。

过去10年间，北京燕山石化依靠科技进步，制定能源，“减量化，再利用，再循环的循环经济”，资源利用率显着提高。 “十五”末和“九五”初期相比，创造增加值占原油吨（按目前价格计算）从497元到一千一百〇一元，面积122％的增长，在能源产出万下降55％，万元产值用水量下降72％，人民币的产值化学需氧量排放量下降76％。

“十五”期间，燕山石化炼油和化学品的主要单位，进行了一系列技术改造，产品结构调整和扩大，同时工厂的生产能力，经济和技术指标，设备更率增加。乙烯装置，例如，在2001年之后的第二轮改造完成后，燕山石化从四千五点○○万吨生产能力/年提高到71万吨/年，能耗，物耗明显降低，其中的整体能量824.65千克标准油/吨下降到690公斤标油/吨，裂解炉热效率提高了消费9个百分点;裂解气压缩机的效率，增加8个百分点;乙烯收率增加0.5％，比过去。 130万吨/年中压加氢裂化装置，70万吨/年的丙烷脱沥青装置，以及两套节能，如在2005年完成的一系列催化转化装置与2000年相比，高标号汽油从46.69％上升至72.19％上升，从69.69％至73.8％轻质油收率;磨去九十三点三九公斤标准油/吨下降到75公斤标油/吨，综合能耗。

2006年正在进行的10000000吨综合利用年/的副产品炼油系统，改革石油焦，燕山石化的支持两个三一〇吨石油焦为燃料建设年/ h循环流化床锅炉。锅炉的燃烧效率，燃料，适应性广，不同的燃料可以达到98％-99％的燃烧效率。此外，燕山石化电站锅炉还将被集成化工系统改造，建设大型锅炉的重点，是为石油的一部分关闭锅炉，热效率将提高到93％。

燕山石化注重发展和应用高新技术，其生产工艺，最大限度地作为一种资源产生的废物转化，把废为宝的伤害，同时，既减少对自然资源的消耗，而且还减少污染物排放，制定企业的发展新空间。06.9.5
