According to the “Gansu Economic Daily†report, Huating’s 600,000 tons of coal-to-methanol project is a major coal chemical project that is jointly developed by the local enterprises. The project is implemented by Huating Zhongyu Coal Chemical Co., Ltd. The estimated total investment is 2.899 billion yuan, covering an area of ​​69.6 hectares. It is planned to be put into use by June 2008. Up to now, the Gansu Provincial Government has approved plans for the Huating Industrial Park. Huating's 600,000-ton coal-to-methanol project has been approved by the Gansu Provincial Development and Reform Commission, and has already met the conditions for commencement of construction.
The project has high profitability, anti-risk capability and driving ability. After it is completed, it will consume 1.8 million tons of raw coal annually, annual sales income of 1.04 billion yuan, annual profit and taxation of 420 million yuan, after-tax profit of 200 million yuan, and internal rate of return. (after tax) reached 12.1%, the breakeven point was 57.07%, and the total fund recovery period was 7.38 years.
Biogenic insecticides include: â‘ preparations of effective insecticidal ingredients extracted from higher plants, such as natural pyrethrin, rotenone, etc.;
â‘¡ Insecticides made from living organisms mainly include fungi (such as Beauveria bassiana), bacteria (such as odontobacillus) and viruses (such as Bacillus borer).
â‘¢ Insect physiological active substances, such as pheromones.
Chemical synthetic pesticides mainly include: Inorganic insecticides (e.g. White arsenic As2O3, Sodium fluosilicate, Na2SiF6, etc.), organochlorine insecticides (such as chlordane, BHC, DDT, toxaphene, etc.), organophosphorus insecticides (such as dichlorvos, trichlorfon, Dimethoate, malathion, chloraphenone, etc.), carbamate insecticides (such as carbaryl, sulfenocarb, etc.) and pyrethroid insecticides (such as fenvalerate, cypermethrin, etc.).
The main ways in which insecticides can kill pests are:
â‘ Touching agents enter the body through the epidermis of the pest and play a role, causing the pest poisoning and death;
â‘¡ Gastric toxic agents are absorbed by the stomach and intestines directly after being eaten by pests, causing them to die of poisoning;
â‘¢ Some fumigation drugs are volatile, and their vapors enter the body through the respiratory tract of pests, causing them to die of poisoning;
(4) ingestion drugs are first absorbed by the crop, and conducted to the whole plant, when pests ingestion, eating crops, so that it died of poisoning.
The largest coal chemical project in the northwest started
The largest coal mine project in northwestern China, the only coal chemical project in Gansu Province, and the backbone project for the integrated development of Hua Ting Coal Power Integration and Transportation Co., Ltd. - Huatin’s 600,000 tons coal-to-methanol project environmental impact report was completed. Last year's Dec. 29th, the State Environmental Protection Administration finalized the review. After the study, it was approved by the State Environmental Protection Administration Circular [2007] No. 9 on January 11. At this point, the conditions for the full-scale construction of the project have already been met. This is the second coal-to-methanol project in China that has passed the national environmental assessment.
