“Vigorously promote energy-saving emission reduction, construction, ecological province of Hainan,” “building an environment-friendly modern industrial city” … … This morning, CNOOC 800,000 tons of methanol project started the ceremony site, one side surface of the banners flapping in the wind is so full of words. Build the project into environmental protection projects, energy-saving model, the goal of the project builders.

energy consumption is far lower than the domestic medium-sized methanol plant indicators

In fact, the builders to make such a goal is to have emboldened the.

“The project uses the world’s most advanced technology, strictly in accordance with world-class technical standards and management standards for construction of the building, with outstanding environmental benefits.” said Fu Chengyu, general manager of CNOOC.

It is said that 80 tons of methanol project the main installations in the United Kingdom DAVY technology, with a short process, equipment, small, integrated, high efficiency, small footprint, products, high value-added features.

“The technology is the use of hydrogen recovery, pre-conversion, low-pressure methanol synthesis and PSA (Pressure Swing Adsorption) recovery tail gas and other energy-saving technologies, using new energy-saving equipment and new insulation materials, greatly reducing the energy consumption of methanol production.” China Shipping Project Chemistry Project Director, Wang Hao Fei said.

been estimated that the project total energy consumption per ton of methanol, 31.4 GJ (heating units), far lower than the domestic medium-sized methanol plant 36 GJ of energy consumption indicators, its comprehensive energy consumption has reached the current international large-scale methanol plant the advanced level. At the same time, the technology uses three-tower distillation process technology, product quality, while achieving superior product in China GB338-2004 and U.S. federal “AA” class standard.

annual “eat” carbon dioxide, 252,000 tons

80 tons of methanol project of energy-saving emission reduction effects of the project lies not only used technology, but also benefit from the raw materials used in methanol production .

According to reports, after the methanol production project uses Ledong high carbon dioxide content and low calorific value of natural gas as raw material. Feed gas concentration of carbon dioxide up to 20%, if used for civilian or electricity and so on, will release a lot of carbon dioxide each year on the environment is bound to cause great pollution.

“and we use this set of carbon dioxide by the world’s advanced technology devices that produce methanol, through the feed gas composition can be self-regulating methanol production process of hydrogen-carbon ratio required for the best, without added carbon, to avoid the a period of more carbon-hydrogen steam reforming process less conflict. “Hao-Fei said.

“in accordance with the current situation, and 80 tons of methanol project the main device is the country’s largest single set of production facilities.” Provincial Director of Public letter to Bureau of heavy industry, Fu Chuan-chi said that such a single series of large-scale methanol production plant is currently the first in the country sets. According to reports, the project put into operation, the package can be consumed per day methanol plant is about 760 tons of carbon dioxide annually consumes 252,000 tons.

Ledong natural gas production and the use of methanol is the best use of their way not only saves the consumption of natural gas, but also greatly reducing the greenhouse gas carbon dioxide emissions, with good economic efficiency and outstanding energy-saving emission reduction benefits.

能源大型甲醇突出节能减排

“大力推进节能减排，建设海南生态省”，“建设环境友好型的现代工业城”… …今天上午，中海油80万吨甲醇项目启动仪式现场，其中一个在风中飘扬的旗帜侧面是如此充满了话。建设成环保工程，节能示范项目，该项目的建设者的目标。

能源消费量远低于国内中低规模的甲醇厂指标

事实上，建设者作出这样的目标是有恃无恐。

“项目采用了世界{zxj}的技术，严格按照与世界与环境效益{yl}的优秀技术标准和管理的建筑标准。”傅成玉说，中海油总经理。

有人说，80万吨甲醇项目在英国的戴维技术的主要设施，以短流程，设备，体积小，集成，效率高，占地面积小，产品，高附加值的功能。

说：“技术是氢的回收，利用预转化，低压合成甲醇和PSA（变压吸附）回收尾气和其他节能技术，使用新能源，节能设备，新型保温材料，大大减少了甲醇生产能耗。“中国船舶工程化学项目主任，王郝菲说。

据估计，该项目每吨甲醇能源消费总量，31.4 GJ（供热单位），远远低于国内中低规模的甲醇厂36的能源消耗量指标GJ，其综合能源消费量达到目前的国际大型甲醇装置的先进水平。同时，该技术采用三塔精馏工艺技术，产品质量，同时实现{zy1}的产品在中国GB338 - 2004和美国xx节“AA”级标准。

一年一度的“吃”二氧化碳，252000吨

80甲醇项目的节能减排项目的效果吨，不仅在于所使用的技术，也有利于从甲醇生产的原料。

据报道，在甲醇生产项目利用乐东高二氧化碳含量和天然气低热值为原料。饲料中的二氧化碳气体的浓度高达20％，如果用于民用或电力等，将释放对环境的二氧化碳每年大量使用，势必造成巨大污染。

“我们使用世界上先进的技术设备这一套二氧化碳生产甲醇，通过气体成分的饲料，可以自我调节不添加碳甲醇生产过程中氢碳比的{zj0}要求，以避免更多的碳一期蒸汽重整制氢过程中减少冲突。“郝飞说。

“根据当前形势下，甲醇80项目的主要设备是全国{zd0}的生产设施一套吨。”省处处长信重工业，傅狷到局基表示，这种大型甲醇生产装置单系列是目前全国{dy}位集。据报道，该项目建成投产，该程序包可以甲醇厂每天消耗约760万吨二氧化碳，每年消耗二十五点二万吨。

乐东天然气生产和使用的甲醇是他们的{zj0}使用方式不仅节省了天然气消费量，而且还极大地减少了温室气体二氧化碳的排放，具有良好的经济效益和优秀节能减排降低的好处。08.11.18
