Chemical companies are energy-hungry . How to play a greater role limited resources , the chemical industry is the focus of concern , but also Hao source who has been pursuing. Hao Yuan Chemical in water, coal , gas and so do some useful exploration into practice , has made great economic and social benefits .

1 , process optimization , root out potential

Chemical production process saving is one of the most potential. Hao source to resource conservation in the daily management , conservation awareness campaigns to the hearts of every employee to increase recycling to reduce the waste of resources, economic benefit.

By observe and learn from the industry , the two companies have increased low-pressure methanol production plant , not only reduces the production system resistance , saving energy , temperament purification process , but also improve the methanol production. At the same time out of the traditional , copper wash behind the production process , reducing copper acetate, and other material consumption , reducing the ice machine load , reducing the ammonia unit power consumption and equipment maintenance costs. Up to now the initial formation of high , medium and low methanol production plant , namely alcohol alkylation high pressure , medium pressure linked alcohol , medium-pressure and low-pressure methanol alcohol alkylation .

Improve gas recovery efficiency , reducing the effective gas losses. Hao source has released ammonia gas tank , ammonia synthesis gas release and the release of gases and systems morpholino gas recovery and utilization of sewage . Ammonia, hydrogen and nitrogen was passed through a high pressure , high temperature, by means of a complex catalyst synthesis gas . Where the effective gas is hydrogen , in addition to production and supply outside the front section , how to improve the hydrogen recovery is essential for ammonia production . The company has invested and increasing the membrane hydrogen extraction set , PSA PSA mention two hydrogen and ammonia recovery set for the release of ammonia and hydrogen gas washing and raised . By washing the gas ammonia content to a minimum. Recycling is a low concentration of ammonia available resources , water treatment and conversion jobs as a means of regulating water quality . High purity hydrogen gas through the system back into the production line for the production . The exhaust gas contains a high concentration of methane ignition source is one of the "three mixed furnace " will help improve the boiler furnace and steam production . Meanwhile, the company focused on the various positions concentrated ammonia production system recycling sewage gas , oil and water separated by gas return to the production system .

Strengthen the production cycle using an internal system to reduce leaking , especially desulfurization liquid carbon C class production materials consumption. While ensuring the purge gas , the daily sewage recycling line provided for recycling . Gas is washed out of the system , reducing the amount of the gas out . When recycled material reaches a certain concentration , and then pumped into the system to re- use . Improve material utilization, reduce the cost of pollution and sewage water .

2 , scientific management, utilization

Water as one of mankind's living conditions , but also the chemical companies continued to produce an important condition . Hao Yuan Chemical attaches great importance to save every drop of water, from the details begin to reduce the loss of water once , increasing the recycling rate . From the production , use, to recycle all aspects of strict management. Water treatment chemical production of desalinated water is the main source of water quality has a direct impact on the production of steam boilers and steam turbine safe operation. After initial treatment sand filter water from deep wells and production processes control, remove impurities in the water , carbon dioxide and calcium and magnesium ions by the pump pressure for production use. Water quality analysis of data from controlled transformation and circulating water systems and sewage water quantity , water and drainage to avoid blind . In each catchment level gauge set up , easy to position the operator to observe and adjust . While the urea resolved as part of the waste processed by the cooling water circulating water sources jobs , improve water utilization.

Steam is necessary for chemical production of a resource . Both chemical raw materials , but also the exchange of heat. Steam classification, integrated use is HaoYuan daily production management in a significant effect . After transformation, such as desalination of water off the job becomes heat after re-entering the deaerator further heated oxygen, pressurized by the feed pump into the boiler system , high pressure steam from the water into 4.5MPa . By 1.25MPa pressure steam turbine backpressure steam pressure or external use . Turbine can generate electricity for production use, but also to achieve the purpose of the steam pressure .

The production jobs in the use of steam , great attention to conservation. When many devices need to be heated or heat , in addition to equipment and piping insulation , the operator or the reference gas analysis data related to temperature parameters, regulating the production process through self-adjusting valves to avoid steam wastage. Steam condensate after use , the majority of the collection tank through line back through the pump to build pressure for the gas, blowing atmosphere and transform jobs continue to be used .

3 , changing concepts , forge ahead

Coal is necessary for chemical production resources . To further save energy , reduce production costs , the company transformed the coal concept - lump coal and bituminous coal ( referred to as " two coal" ) . Hao source being taken intermittently fixed gas technology for coal requirements are very demanding , mainly coal consumption is a smoke-free lump coal . Lump coal gas furnace control conditions , to ensure that supply and optimization temperament is very beneficial. But with the increasingly tense coal resources , coal supply pressure, to produce a huge challenge. Coal must change the concept - blending coal ( ie, coal briquettes and rods ) . Company leaders and learn through the decision on increasing coal production line, change the status quo . The crushed coal and coal froth Aberdeen adding a binder by stirring, extrusion, drying and coal briquettes rod becomes available. Just the beginning of the production of coal can not start, I do not know blending ratio. After the gas station more influence , less economic reach . Production department and workshop technicians set up a special research team to overcome , to overcome the complex multi- out , gas stove instability and poor conditions unfavorable factors , and the adjustment process of combining single furnace and batch trial burn . So far, two briquette production line, burning coal 1120t, bring considerable economic benefits to the enterprise .

The " three mixed furnace " has changed the bituminous coal -based boiler producing steam energy model. Three major industrial gas furnaces mixed , blended with a small amount of slag and mixed bituminous coal as fuel combustion produces high-pressure steam , mainly for production systems and back-pressure unit used. Currently, the remaining boilers are used with bituminous coal slag blended approach to production .

4 , energy-saving , innovative

Gas cooling has been one of the chemical companies tried to solve the problem, especially in the summer to produce a chemical challenge . Whenever the arrival of summer , due to the amount of hot weather cause the compressor to cheer poor , low yields, high consumption of a vicious circle . In addition to strengthening Tabb cold water backwash cooler blowing compressor cylinder , but also increase the lithium bromide device , reducing the compressor into a gas temperature, increase the amount of compressor cheer improve summer production bottlenecks . While the compressor section components, such as cylinders, valves and other technological innovation to improve the single output rate.

In addition, part of the production system Hao source pump additional frequency control , energy saving pumps into the cold slag machine into operation and promotion of DCS control systems , real-time monitoring of production and operation, reducing the ammonia unit energy consumption , improve the production level of automation , reduce staff labor .

Currently, Hao Yuan Chemical in the utilization of resources in the primary and exploratory stage . In the pursuit of economic and social enterprises while maximizing resource recycling and energy saving will be endless.
