The company invests mount a horse the project of form a complete set of cooking of defer of 1 million T hydrogenation of 800 thousand T refines and 30 thousand T is sulfureous reclaim project, quality of farther promotion product, reclaim effectively the 2 oxidation sulfur in waste gas, have major economic benefits and social benefit; to invested many yuan 6000 to build two dry gas to make hydrogenous device, make waste gas reclaims rate achieved 95%, reduced the discharge capacity of waste gas substantially, reduce; of the cost that make hydrogen to be in greatly at the same time more than heat, beyond pressure, of more than gas used a respect integratedly to carry out 22 technical reformation, make enterprise ton the banner level that oily treatment specific power consumption reached industry of domestic person of the same trade.

公司投资上马了100万t延迟焦化的配套项目80万t加氢精制和3万t硫磺回收项目，将进一步提升产品质量，有效回收废气中的二氧化硫，具有重大的经济效益和社会效益；投资6000多万元建设了两套干气制氢装置，使废气回收率达到了95%，大幅度降低了废气的排放量，同时大大降低制氢成本；在余热、余压、余气的综合利用方面实施了22项技术改造，使企业吨油加工能耗达到了国内同行业的领先水平。

In a traditional total quantity distillation setup or a half micro-distillation setup, the separation and absorption of ammonia and constant volume must be done separately, so the analyzing program is complex and needs long analysis time. By the rapid azotometer (Type: NC2), the ammonia in the waste water could be analyzed through one step which includes separation, absorption and titration. Compared with the tradition analysis methods, the ammonia-N in waste water can be analyzed more quickly.

The biological hydrogen is very important to solute the energy crisis and the environmental pollution. Our country works out the organic waste water zymotechnics biological hydrogen technology by the tired of oxygen active sludge and the organic waste water as produces raw material. It is proved by the experiment in HIT. This research was discovered first in our country and foreign and realized the experimental scale non-fossilization mold mushroom spawn for a long time to continue producing the biological hydrogen technology. It also realized the experimental scale continue to produce the hydrogen for a long time. It was a domain significant breakthrough in biological hydrogen.
