【Haichuan Equipment Guessing Game】Developed in the 1970s – the core equipment for chlor-alkali chemical industry

The hydrogen compressor was personally purchased by Mr. Wu Yunchu from this [Haichuan Equipment Guessing Game]. It has been in operation along the Suzhou River for nearly a hundred years: https://bbs.hcbbs.com/thread-2766226-1-1.html (Source: Haichuan Chemical Industry Forum). However, this compressor is also related to Mr. Wu

Shanghai Tianyuan Chemical Factory was established in the 18th year of the Republic of China (1929) by Zhu Ziqian, Zhang Yiyun, and Wu Yunchu, who pooled together 200,000 silver yuan for its creation. It was initially named Tianyuan Electrochemical Factory Co., Ltd.; Wu served as the general manager. The factory was located at No. 420 Baili South Road (the back door of today’s No. 2365 Changning Road), covering an area of 24 mu. A used complete set of equipment from the French Far East Chemical Company was purchased from Haiphong, Vietnam, and the plant came online in November of the 19th year of the Republic era, becoming the first chlor-alkali factory in the country. At that time, there were over 60 employees, with a daily production of 2 tons of caustic soda, 2 tons of hydrochloric acid, and 3 tons of bleaching powder; the \"Taiji\" trademark was used. After four capital increases, the total capital amount reached 1.05 million yuan in 1937, and horizontal electrolyzers manufactured in-house were used to expand production scale.

Following the August 13th Incident in the 26th year of the Republic of China, the factory was moved to the north bank of the Jialing River in Chongqing, which is where the Tianyuan Chemical Factory stands today. In the 30th year of the Republic era, the company’s capital was increased to 3 million yuan, with Jincheng Bank holding 57.7% and Wu Yunchu holding 42.3%. In October of the 32nd year of the Republic of China, the capital was increased to 10 million yuan; Wu Yunchu held 53% of the shares while the Resources Committee held 47%, making it a joint venture between the government and private investors. In the 33rd year of the Republic of China, a branch factory was built in Yibin, Sichuan, and it began operations in the 35th year of the Republic of China – this is the present-day Yibin Tianyuan Chemical Factory. During the period of Japanese occupation, the Japanese forces took control of the factories in Shanghai, seized their equipment, and established the Jiangnan Chemical Industry Co., Ltd. in Pudong. In September of the 34th year of the Republic of China, the Shanghai Tianyuan factory and the Pudong Jiangnan Chemical Factory, formerly known as Jiangnan Chemical Industry Co., Ltd., were taken over successively. In May of the 36th year of the Republic of China, the Tianyuan factory in Shanghai resumed production at its original location.

On June 10, 1949, the Shanghai **Control Committee sent personnel to take over the shares of the former Resources Committee; Tianyuan Electrochemical Factory thus became a joint public-private enterprise, under the jurisdiction of the Ministry of Industry of the East China Military and Political Committee. In August of the same year, the Pudong Jiangnan plant was closed, and its staff and equipment were integrated into the Tianyuan plant. In 1952, the management structures of the Tenma and Tenri factories were merged. In 1953, it was under the jurisdiction of the Chemical Industry Administration Bureau of the Central Ministry of Heavy Industry. The following January, Tianyuan and Tianli factories were officially merged, and on September 1st they were renamed the Jointly Operated Shanghai Tianyuan Chemical Factory. In 1956, it came under the jurisdiction of the Basic Chemical Industry Administration Bureau of the Ministry of Chemical Industry. That year, the former Tianli Plant was separated and transformed into the Fertilizer Industry Research Institute, which is today’s Shanghai Chemical Research Institute under the Ministry of Chemical Industry. In October of the same year, the pottery workshop was transferred to Yixing to support construction in other provinces and placed under the jurisdiction of the Jiangsu Provincial Department of Industry. In January 1957, Xiesheng Machinery Factory and Dushunchang Machinery Factory were merged into Tianyuan Factory. In 1958, the Tianyuan factory was under the Shanghai Chemical Raw Materials Industry Company. In the same year, land was acquired on the west side of the factory to build a PVC workshop, while a chlorosulfonic acid workshop was constructed at the factory headquarters in the east area. In 1959, 60 hectares of land were acquired to build the Wujing branch factory; in November, it was separated from the Tianyuan factory and renamed Shanghai Electrochemical Factory. In 1960, the Tianyuan factory came under the jurisdiction of the Shanghai Chemical Industry Bureau. In 1980, 26,000 square meters of land along with over 600 employees from the nearby Shanghai Stone Powder Factory were transferred to the Tianyuan Factory
