【Haichuan Chemical Salary Updates】Sinochem Quanzhou’s million-ton ethylene plant set to go into operation in June
Thread Content
The project is expected to go into operation in June 2020! The Sinochem Quanzhou Refining and Chemical Integration Project (Phase II) has a total investment of around 32.5 billion yuan. Building on the existing 12 million tons per year refining facility that is already in operation, the project involves the construction and expansion of 13 new refining and chemical units, along with related storage, transportation, port, and utility facilities. This will raise the crude oil processing capacity to 15 million tons per year. Additionally, a 1 million tons per year ethylene production facility will be built (including 800,000 tons per year of aromatics). The project is located in the Quanhui Petrochemical Industrial Zone (Dongqiao Town), Hui’an County, Quanzhou City, Fujian Province, covering an area of approximately 6,541 mu. The process units and scale of the project include 11 units in the chemical processing area, such as an ethylene cracking unit with a capacity of 1 million tons per year, an EVA unit with a capacity of 100,000 tons per year, an HDPE unit with a capacity of 400,000 tons per year, EO/EG units with capacities of 200,000/500,000 tons per year, PO/SM units with capacities of 200,000/450,000 tons per year, a PP unit with a capacity of 350,000 tons per year, a butadiene extraction unit with a capacity of 120,000 tons per year, MTBE/butene-1 units with capacities of 100,000/30,000 tons per year, a pyrolysis gasoline hydrogenation unit with a capacity of 500,000 tons per year, an aromatic extraction unit with a capacity of 350,000 tons per year, and a p-xylene unit with a capacity of 800,000 tons per year ； There are 2 sets of units for oil refining, including a newly built atmospheric distillation unit with a capacity of 3 million tons per year and a refinery dry gas pre-purification unit with a capacity of 450,000 tons per year.
Do Sinochem and Sinopec both have integrated projects in Quanzhou?
This is the approximate engineering volume for millions of tons of ethylene ===========================
It seems there is only one large oil refinery in Quanzhou; Quanzhou has an LNG receiving station
A construction period of 26 months is quite reasonable
There is also the localization of the three ethylene plants using the KBR process
You’re referring to the EVA reaction dam, right? CNPC Refining also carried out construction on it last year; the pictures are from Yulin, Shaanxi
The foundation of the largest reaction dam for the 100,000-ton/year EVA plant was poured on schedule 2018-11-05 Source: Sinopec News Network Print article Petrochemical news According to a report from Sinopec News Network (Gao Mingliang), thanks to careful organization and implementation by the project team in charge of the Zhongke Refining and Chemical Project, 80 construction workers worked hard over 50 days to complete the pouring of the foundation of this largest reaction dam for the 100,000-ton/year EVA plant on November 3, thus meeting the first deadline set for the construction of this dam. The reaction dam is the core facility of the EVA plant, also known as an explosion-proof wall. It houses an ultra-high-pressure reactor with an operating pressure of 3300 kilograms and a maximum test pressure of 3600 kilograms. It is a reinforced concrete dam designed with extremely strong explosion-proof capabilities, and its technical requirements are very high, making construction quite challenging. The foundation of the bottom slab of this reaction dam is 83.5 meters long, with widths of 22 meters and 32 meters respectively; the thicknesses of the slabs are 0.7 meters and 1.5 meters respectively. For this foundation, 500 tons of reinforced steel bars need to be used, and 3,015 cubic meters of concrete must be poured. Shi Jian Company attaches great importance to this matter; in order to ensure that the reaction dam is built safely, to high quality, and on schedule, it arranges for construction personnel from various specialties to thoroughly study the blueprints in advance and understand the design requirements. In conjunction with the construction, supervision, and contracting units, invite the designers to provide explanations and ensure thorough review of the drawings. A detailed construction plan is carefully prepared, with a thorough schedule established. The construction workers are given training on technical standards and quality requirements, and comprehensive safety instructions are provided. The technical challenges and key points associated with each stage of construction are explained in detail so that everyone understands them thoroughly and remembers them well, ensuring that the dam is built strictly in accordance with the planned scheme. To ensure the progress and quality of the construction of the reaction dam foundation and to achieve high-quality results, personnel in charge of construction organization, safety, and technical quality carry out on-site supervision. In particular, for the ten construction stages of \"site positioning and marking, earthwork excavation, pile head treatment, foundation trench inspection, cushion pouring, axis elevation verification, rebar binding, formwork installation, concrete pouring, and foundation curing\", Shijian, together with the owner, supervisor, and contractor, conducts thorough joint inspections for each stage ； For the quality of steel bar binding, four inspection steps must be strictly followed: 1. Inspection of the type, specification, quantity, and position of the longitudinal load-bearing steel bars ； 2. Connection methods for rebar, as well as inspection of joint location, quantity, and area ； 3. Inspection requirements for the type, specifications, quantity, and spacing of stirrups and transverse reinforcement ； 4. All rebar must be free from oil, scale, and other contaminants and must be kept clean. Thanks to strict quality control, the joint inspections of the foundation rebar and formwork installation before each pouring are always successful. The foundation of the reaction dam is extremely large in volume. To ensure the quality of concrete pouring, it was constructed in three stages. Whenever batches of C35 ready-mixed concrete arrived at the site, Shijian would first check the slump of the concrete, conducting two checks per working shift ； To prevent cold joints in the floor concrete during construction, the technique of \"pouring in layers and vibrating each layer\" is employed in every pouring operation. A secondary vibration process is also used, with the vibration being carried out strictly within one to two hours after pouring. It is prohibited for the vibration rod to come into contact with rebar, formwork, embedded components, etc., during vibration. The timely completion of the reactor dam foundation created favorable conditions for the full completion of the construction of the reactor dam structure by the end of January 2019.
