Xi'an Dongxin Petroleum Equipment Factory Co., Ltd. was established in 2000 and is located in the High tech Zone of Xi'an City, Shaanxi Province. The company's business has always focused on technical services for pressurized maintenance of oil and gas wellheads, a series of products for high-pressure gas well wellhead protection devices, and intelligent security systems for oil and gas pipeline networks. The company adopts a development model mainly based on independent research and development, with joint development of industry, academia, and research. It has successfully developed 40 categories and 500 different series of products, and actively moves towards systematic solutions and system integration. The products and technologies are characterized by safety, efficiency, economy, and environmental protection, and are widely used in the production and development of natural gas in oil and gas fields such as Changqing, Daqing, Liaohe, North China, Xinjiang, Qinghai, Jianghan, Dagang, Southwest, and Yanchang. The company is a professional designated manufacturer of oil drilling and production equipment for international companies such as PetroChina, Sinopec, and CNOOC.

 

 

The company has two research and development centers, one experimental base, and one manufacturing plant. The products and operation services developed by the company have obtained more than 80 relevant national patented technologies, special equipment manufacturing licenses issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, work safety licenses issued by the Shaanxi Provincial Government, three API (AMERICAN PETROLEUM INSTITUTE) monogram use qualifications, passed the ISO9001 quality system certification, and obtained the qualification of import and export enterprises of the China.

 

For the past 20 years, Dongxin Petroleum has always been dedicated to serving the development of the oilfield, focusing on technology research and development in the field of oilfield safety production, providing practical and reliable solutions and application systems for the oilfield. The company has successively become a strategic partner with PetroChina, Sinopec, Changqing oil field and Total Group, and has established a long-term stable service relationship with large domestic oil and gas production enterprises. At the same time, the company also has exchanges and visits with famous oil and gas companies and energy service providers in Saudi Arabia, Sudan, Oman, Libya, Nigeria, Russia, Iraq and other countries, and has reached many project cooperation.

 

In 2019, the "Safety Steward in Our Work - Oil and Gas Pipeline Network Full time Intelligent Security System" was officially successfully developed and launched into the market for application, leading the opening of the intelligent era of oil and gas pipeline security system 4.0, realizing the leap from artificial to intelligent, and contributing our own strength to the grand goal of "Made in China 2025".

 

 

In February, Xi'an Dongxin Petroleum needs to produce a batch of butene-1, and ACHIEVE CHEM get this opportunity to provide some

 

Butene-1 is an important petrochemical raw material that can be obtained through butane dehydrogenation reaction.The following is the production process of butene-1 and some required chemical equipment and reactions:

 

 

(1) Raw material preparation: Treating butane as a raw material usually requires pre-treatment operations such as degassing and desulfurization.

 

(2) Refinery unit: The treated butane is fed into the refining unit and undergoes dehydrogenation reaction of butane through appropriate heating and catalyst action.

 

(3) Separation and purification: After dehydrogenation reaction, the generated substrate contains butene-1, butene-2, and other impurities. Separate the target product butene-1 from the mixture through separation and purification processes.

 

 

 

(1) Reactor: In refining units, butane dehydrogenation reaction is usually carried out in the presence of a catalyst. This reaction usually uses a fixed bed or fluidized bed reactor. The reactor requires high temperature and pressure resistance, and high-temperature and high pressure reaction.

 

(2) Heating furnace: In order to cause butane dehydrogenation reaction to occur, a heating furnace is required in the refining unit to heat butane and provide the necessary temperature conditions for the reaction. This process requires the use of high-pressure hydrogenation reactors.

 

(3) Separation tower: In the separation and purification process, a separation tower is usually used to distill the product to separate butene-1 and other components, and the

 

(4) Steam recovery device: In order to improve energy utilization efficiency, steam recovery devices are usually used to recover and utilize the generated waste heat steam.

 

 

During the feeding process of the newly added unit of butene-1 unit, it is necessary to ensure both smooth progress and stable operation of the device. ACHIEVE CHEM arranges technical personnel to be on duty 24 hours a day, adjust process operations in a timely manner, overcome adverse factors such as material balance difficulties and lack of operating experience, and successfully produce qualified products. The device operates smoothly throughout the entire process.
