At the 2011 annual meeting of the CO2 Professional Committee of the China Industrial Gas Industry Association held in Tianjin, a representative bluntly said: “The price of CO2 in Jiangsu Province has already been lower than the cost of recycling enterprises and mining enterprises according to law.†In most countries, a lot of manpower has been spent, Material resources for CO2 capture and storage, and the extraction of CO2 from gas wells has yet to be discussed. There are also illegal corporate reselling and mining, low-cost sales, disrupting the order of the carbon dioxide market, and reducing the profitability of CO2 recovery from industrial tail gas and reducing its recycling. The enthusiasm directly hinders the promotion of energy saving and emission reduction.
Increasing illegal behavior
At present, China's annual carbon dioxide production is about 6 million tons, and the main production method is industrial waste gas recovery, of which about 15% comes from gas field mining. Because recycled gas is at a disadvantage in terms of cost compared with gas, recently there have been serious illegal mining and illegal sales activities in the carbon dioxide gas fields such as Jiangsu Taixing, Zibo, Shandong, Jilin Songyuan and Heilongjiang Daqing. Among them, Jiangsu Taixing is the most typical.
Huangqiao Town in Taixing City has the largest CO2 gas field in China and there are 18 CO2 production and sales companies around. The Taixing City Government had reached a mining agreement with the East China Petroleum Bureau of the Sinopec Group. Sinopec Jiangsu Huayang Liquid Carbon Co., Ltd. is responsible for mining and production according to the law, with a mining capacity of 500,000 to 800,000 tons per year, and signed with 18 companies respectively. "CO2 Feed Gas Supply Agreement." According to the agreement, carbon dioxide gas can only be used as a raw material for production, and it must not be used as raw gas or purified gas to be directly sold to outsiders, and it must not be transferred to third parties. However, under the drive of interests, in addition to Huayang Liquid Carbon, the remaining 17 companies violated the contractual stipulations, exceeded the scope of operations, and directly sold carbon dioxide as raw material gas to earn the difference. What is even worse is that some companies not only illegally used gas fields to produce industrial carbon dioxide, but also used holes in gas fields leading to Hua Yang’s carbon dioxide production plant to steal gas fields. In order to expand sales, they still do not hesitate to illegally produce carbon dioxide. Dumping in the market.
Interest drives the market in disorder
What is the difference between the cost of stolen gas and recycled gas? Industry insiders calculated for the reporter. Taixing underground mining of carbon dioxide purity of 99.9%, is a high-pressure self-injection method to produce, the jet is a gas-liquid mixed phase, the cost per ton of electricity is only 40 yuan, Huayang need to pay mineral resources fees and management fees total 155 yuan per ton, In addition to mine maintenance and other costs, the cost per ton was nearly 300 yuan. Taixing's other companies normally purchase gas from Huayang at 160-200 yuan/ton, and if pure gas is sold after purification, the cost is comparable to that of Huayang. However, if the raw gas is stolen, the cost is only about 100 yuan/ton. In addition, underground carbon dioxide is 3%. Oil, can be separated from the condensate sold at high prices.
Due to the different CO2 concentration in the exhaust gas, the energy consumption recovered from different tail gas varies greatly. The cost per ton of electricity is between 150 and 350 yuan, plus other costs, and the total cost is 250-450 yuan. For example, if the concentration of exhaust gas is 80%, the total cost per ton must exceed 300 yuan. In terms of equipment investment, the investment in recycling equipment is huge, and the exhaust gas equipment with a high concentration of carbon dioxide needs to invest tens of millions of yuan, and the low concentration even reaches 100 million yuan. Gas field gas does not require a compression system, and investment in recycling companies should be reduced by half.
As a result, pirate mining companies used cost advantages to direct a price war. According to reports, the annual demand for carbon dioxide in East China is about 1 million tons, and the recovery devices are mainly distributed in Jiangsu and Shandong, with a total of more than 40 enterprises and a total production capacity of more than 1.4 million tons/year. However, the annual (legal + illegal) supply of carbon dioxide from underground mining in Taixing City has exceeded 1 million tons, exceeding the demand in the entire East China region, and nearly 1 million tons/year of production capacity of recycling companies has lost its market. To seize market share, some companies in Taixing kept declining prices and even sold gas illegally at a price of less than RMB 200 per ton. Recycling companies had to reduce their selling prices, and the entire market was in chaos. The price of carbon dioxide dropped from 600 to 700 yuan per ton in 2003 to 300 yuan per ton in 2010, even once to 220 to 230 yuan per ton, which is lower than the cost of recycling companies and mining companies. At present, carbon dioxide recovery companies in Jiangsu province are in trouble and the operating rate is low. Nanjing Alpha Company only reached 56% of its total production capacity. Except for a few companies in southern Jiangsu who can normally produce due to fixed customers, other companies are either discontinued or semi-discontinued. In the state, 3 have been completely discontinued.
Prohibition of direct exploitation is imperative
The Secretary-General of the China Industrial Gas Industry Association, Mr. Chunchang said that this illegal reselling and robbery by enterprises has not only disturbed the market order, but more importantly dampened the recovery and emission reduction enthusiasm of tail gas recycling companies. It is understood that there are currently 21 recycling companies in Jiangsu Province (a total of 23 units) with a design capacity of 1.1 million tons/year and an annual production capacity of 900,000 tons. Recycling is only the tip of the iceberg for carbon dioxide emissions, and a large amount of carbon dioxide has not been recycled. Only when the price of carbon dioxide tends to be reasonable can more enterprises be encouraged to install the exhaust gas recovery device.
He emphasized: "China has promised the world that the carbon dioxide emissions per unit of GDP will be reduced by 40% to 45% in 2020 compared with 2005, and the Ministry of Land and Resources has already begun to plan the trial of CO2 refill landfill. The issue of abandoning mining and illegal sales is directly The underground mining of carbon dioxide itself is inconsistent with the goal of reducing emissions in China, adding to the pressure of total carbon dioxide emissions control. The government should ban carbon dioxide gas wells as soon as possible.†He also said that CO2 companies are ready to stop gas wells from mining. Nor will it cause major market volatility.
