In September, Mingsheng environmental protection Co., Ltd. received good news again. Relying on the strong support of the technical team, the efforts of the staff and the perfect investigation of the flue gas de whitening project of Jinmei Minghua, the company successfully signed a contract with Henan xinlianxin chemical fertilizer Co., Ltd. to upgrade the boiler room of xinlianxin industry, supporting flue gas ammonia desulfurization of 1 x 300 t / h high temperature and high pressure pulverized coal boiler, and Smoke whitening EPC project.
Henan xinlianxin Chemical Co., Ltd. is a joint-stock private enterprise reformed from the former Henan Xinxiang Chemical Fertilizer Plant in August 2003, located in Xinxiang economic development zone. The company covers an area of more than 600000 square meters, with more than 2600 employees and more than 500 middle and senior professional and technical personnel. The company has a total assets of 1.9 billion yuan. Xinlianxin company has been awarded a series of awards, such as "national advanced chemical fertilizer production enterprise", "advanced enterprise of comprehensive evaluation of provincial economic benefits", "clean and civilized factory", "top 100 enterprises with scientific and technological development strength of large and medium-sized professional enterprises in Henan Province", and is the leader of the same industry in Henan Province. In July 2006, xinlianxin chemical company separated urea, compound fertilizer and methanol business and established Henan xinlianxin fertilizer Co., Ltd.

It officially entered the international capital market and became the first chemical fertilizer enterprise listed in Singapore in China.
The NOx emission concentration of boiler flue gas after SCR denitration is ≤ 50mg / Nm3, and the dust concentration of flue gas entering desulfurization device after dedusting by bag filter is ≤ 20mg / Nm3. Under the rated evaporation capacity, the flue gas volume at the inlet of the desulfurization device is about 410000 Nm3 / h, the flue gas temperature is 140 ℃, and the calculated SO2 emission concentration is 1330mg / Nm3, which meets the ultra-low emission requirements after the ammonia desulfurization device.
The whole process of desulfurization with Benxin ammonia Co., Ltd Smoke whitening The scope of all work, that is, the design of various systems, equipment, civil engineering, equipment and materials procurement, manufacturing, inspection, experiment, shipping; equipment and materials supply, unloading, storage; equipment, pipeline system installation and construction; system commissioning, training, 168 h trial operation; performance assessment, acceptance, defect elimination, after-sales service, etc.
We believe that with the support of Mingsheng environmental protection and heart to heart leadership, the staff of the two units will devote themselves to work hard to make a high-quality project, and the project will certainly cause a strong impact in the Central Plains, and once again create a benchmark for ammonia desulfurization!
