Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core Views of the Report - China's current butadiene plants are mainly integrated, with state - owned enterprises accounting for 81.22%, mostly concentrated in PetroChina and Sinopec. High production costs have led to the shutdown of most oxidation - dehydrogenation process plants [2][7][12] - The proportion of butadiene plants with downstream support is 42.7%, and state - owned plants in this category account for 67.66%, with nearly half located in East China [2][12][36] - The four major areas with high demand for butadiene are cis - butadiene rubber, styrene - butadiene rubber, ABS, and SBS, accounting for 86.45% of the total demand. Their capacity changes and operating rates are the main factors affecting butadiene demand fluctuations [24][37] - Currently, East China is the main area with a butadiene shortage, while North China, Northeast China, Northwest China, South China, and Central China have varying degrees of surplus. Despite this, China still imports some butadiene due to shortages of certain types [30][32][37] Group 3: Summaries by Related Catalogs 1. Introduction - This is the third in the series of in - depth analyses of chemical plants, focusing on the ownership, distribution of butadiene upstream and downstream plants, and marginal plants. The topic is divided into two parts. The first part analyzes the butadiene plants themselves and the raw material balance between regional plants and their downstream counterparts, while the second part will detail the ownership, distribution, and marginal plants of each major downstream area of butadiene [6] 2. Butadiene Plant Analysis - **Capacity Ownership and Distribution**: As of now, there are 71 butadiene plants in China, including 7 shut - down, 8 under construction, and 56 in production. After excluding shut - down (430,000 tons) and under - construction (1.19 million tons) capacities, the total butadiene capacity is 7.137 million tons. State - owned enterprises account for 81.22%, private enterprises 13.03%, and foreign - funded enterprises 5.74%. Carbon - four extraction process plants account for 93.15%, and butene oxidation - dehydrogenation plants 6.85%. Most plants are integrated, with only a few needing to purchase external raw materials [7] - **Shut - down Plants**: Shut - down plants are mainly in East China (5 plants, 370,000 tons) and North China (2 plants, 60,000 tons). Five are state - owned (250,000 tons, 58%), and 2 are private (180,000 tons, 42%). Most shut - down plants use the oxidation - dehydrogenation process due to high production costs [8] - **Under - construction Plants**: There are 8 under - construction plants with a total capacity of 1.19 million tons. Three are in East China (360,000 tons, 30.25%), 2 in Northeast China (360,000 tons, 30.25%), and the rest in South China, Northwest China, and Central China. The capacity with downstream support is 480,000 tons, accounting for 40.33% [8] - **In - production Plants**: Among the 56 in - production plants, 30 are in East China (3.743 million tons, 52.45%), 8 in South China (1.095 million tons, 15.34%), 7 in Northeast China (930,000 tons, 13%), 4 in North China (575,000 tons, 8%), 3 in Northwest China (404,000 tons), 3 in Central China (240,000 tons), and 1 in Southwest China (150,000 tons). State - owned capacity accounts for 48.8% of the total 6.937 million tons [9][10] 3. Marginal Capacity Analysis of Butadiene - **Plants with Downstream Support**: There are 20 existing plants with a total capacity of 3.076 million tons, accounting for 43.1%. There are also 3 under - construction plants with a total capacity of 480,000 tons, expected to be completed from the fourth quarter of this year to 2026 and 2027. Thirteen are state - owned (2.026 million tons, 65.86%), 3 are mixed - ownership (700,000 tons), 3 are private (220,000 tons), and 1 is a Hong Kong, Macao, and Taiwan joint - venture (130,000 tons). Eleven are in East China (1.661 million tons, 54%) [16] - **Plants without Downstream Support**: There are currently 36 plants with a total capacity of 4.061 million tons. There are also 5 under - construction plants with a total capacity of 710,000 tons. Five plants were shut down between 2008 and 2017, involving a total capacity of 340,000 tons. After excluding shut - down and under - construction capacities, the capacity of plants without downstream support accounts for 43.1% of the existing total. Nineteen are in East China (2.082 million tons), 7 in South China (945,000 tons), 3 in North China (440,000 tons), 3 in Central China (240,000 tons), 3 in Northeast China (290,000 tons), and 1 in Northwest China (64,000 tons). Twenty - six are state - owned (3.071 million tons), 8 are private (710,000 tons), 1 is foreign - owned (200,000 tons), and 1 is a Hong Kong, Macao, and Taiwan joint - venture (80,000 tons) [16][17][18] 4. Butadiene Downstream Demand Proportion and Regional Raw Material Balance Analysis - **Downstream Demand Distribution**: Butadiene is widely used downstream, mainly in cis - butadiene rubber, styrene - butadiene rubber, ABS, SBS, ESBS, and nitrile rubber, as well as two latex categories (nitrile latex and styrene - butadiene latex). The four major demand areas (cis - butadiene rubber, styrene - butadiene rubber, ABS, and SBS) account for 86.45% of the total demand. For downstream plants with external raw material procurement needs, the top four demand areas remain the same, but the structure changes. The external procurement capacity of styrene - butadiene rubber is significantly smaller than that of SBS, and the external procurement capacity of nitrile latex also accounts for a large proportion [24] - **Regional Raw Material Balance Analysis**: By matching the external sales volume of butadiene in major regions with the external procurement demand of downstream areas, it is found that East China is the main area with a butadiene shortage, while North China, Northeast China, Northwest China, South China, and Central China have varying degrees of surplus. The total surplus capacity is basically the same as the shortage capacity, indicating that China's butadiene plants are generally self - sufficient. However, due to shortages of certain types, China still imports some butadiene every year, mainly from South Korea, Southeast Asia, the Middle East, Europe, and the United States [30][31][32]
