Zhongyuan Ethylene's 50,000-ton carbon 4 resource optimization project starts construction

Recently, with the construction of the first pile, Zhongyuan Ethylene's 50,000-ton/year carbon 4 resource optimization project was started to be constructed, marking the company's optimization of product structure and accelerating the comprehensive utilization of by-products and taking new steps. It is also the company's ability to do Outstanding features, take another example of the road to connotation development.

Zhongyuan Ethylene can produce 450,000 tons of cracked mixed carbon each year. The composition of mixed carbon four is 1,3-butadiene, isobutylene, and butene-1. Currently, all the mixed carbon four are used in MTBE/butene-1 plant production. Gasoline Additives and High Purity Butene-1 Products. Due to the high price of butadiene monomer, the price of pyrolysis mixed carbon 4 is obviously higher than that of carbon tetrachloride. Using current processing routes not only results in a waste of 1,3-butadiene resources in hybrid carbon tetra, but also makes The MTBE/butene-1 unit has high energy consumption and high production costs.

In order to reduce the production cost of the C4 integrated utilization device and optimize the use of C4 resources, the company's demand for butene-1 is ensured and the overall efficiency is maximized. The chemical company of the joint-stock company agreed to implement a 50,000-tonne/year carbon four resource optimization reform project for Zhongyuan Ethylene. The total investment of the project is 11.77 million yuan, which is mainly implemented in the MTBE/butene-1 plant. Four new canisters of charcoal are built on the reserved land on the southwest side of the plant area, no new land acquisition, no increase in capacity, environmental protection and occupation Safety and health realize "three simultaneous" and it is expected that the cost can be recovered in the short term.

After the project is completed and put into production, it can sell the butadiene-rich pyrolysis mixed carbon 4 to internal units of the petrochemical group company, which is conducive to the rational allocation and optimization of resources within the system. The relatively low outsourcing price of extracted carbon 4 is used as raw material for butene-1 production. It stops the carbon tetrahydrogenation reactor and increases MTBE production from 19,500 tons to 45,300 tons. It has good market competitiveness and economy. benefit.

Core Barrel&Overshot

Drilling tool assembly (P, H, N and B)
Relevant description of products:
Retrieve the inner tube with an overshot without lifting out the whole rods string to obtain the core, the wireline coring system lifts the underground core sample out of the borehole through the overshot to take back the entire inner tube and conduct sampling analysis. This improves productivity of the work site and guarantees safety of core sample during drilling down.
The system is realized through a fully independent inner tube. During its working, the inner tube does not connect with the overshot but locates at the bottom of the coring Drilling Rod directly (behind the coring drilling bit). An assembly device is installed on top of the inner tube, which includes coring and recycling functions. When the inner tube is full of core sample, the overshot is placed to the bottom from the borehole through a steel wire rope and lifted out by a winch. After the inner tube assembly is lifted to the surface, an empty inner tube is placed to the bottom of the hole to recover the drilling. This improves well drilling efficiency.
Our company provides core barrel assmeblies of different diameters to meet customers' demands. The wireline coring system is applicable for most drilling conditions and standard DCDMA hole sizes (B, N, H and P).
Currently, the company provides two models of wireline coring systems: double-tube and triple-tube
Core barrel assembly: It consists of inner tube and outer tube groups.
The inner part consists of the following parts: spearhead assemly, retrival components, core sample collection component, landing shoulder, stop ring and other parts.inner tube group, independent from outer tube group, collects core sample sample during well drilling.
The outer tube part consists of parts , which includes locking coupling, adapter coupling, outer tube, etc. The outer tube group that is kept at the bottom of the hole all the time holds the inner tube assembly during drilling.
The triple tube coring system AU3 has the same components as the dual-tube. And its interior has a third tube that is known as liner tube of the inner tube.
Liner tube of the inner tube is placed in the inner tube. The triple tube system can realize overall recovery ratio of core sample when drilling stratum with coal, clay or bigger crack. The liner tube or split tube keeps the core sample at its receiving status to collect or load and store easily.
Only N, H and P sizes are available for the triple tube coring system.
