A large-scale centrifugal chiller is worth tens of millions of yuan, and more than 2,000 units used in the petrochemical industry use fluorine-containing R11 (CCl3F) refrigerants. According to the Montreal Protocol on Destruction of Ozone Layer Substances, R11 refrigerants must be banned and eliminated globally in 2010. This means that more than 2,000 installations used by domestic petrochemical companies must be rebuilt or replaced within the year. Prior to this, although companies have carried out technological breakthroughs in the replacement of refrigerants, no one has achieved success.
The technical personnel of water and gas system of Jilin Petrochemical Company introduced that the company adopts the internationally recognized safer refrigerant product R123 to replace and replace the R11 refrigerant, which not only can save the huge unit renewal cost, but also completely solve the R11 leakage and ozone depletion under emergencies. The safety and environmental risks. This achievement has recently obtained the provincial environmental certification certificate, Jilin Petrochemical Company is currently planning to use technology cooperation and other forms to promote its application. According to another report, the technical renovation of the company's chiller refrigerant has created 5.4 million yuan in economic benefits so far.
It is understood that the centrifugal chiller of Jilin Petrochemical Company’s calcium carbide plant bears the task of supplying 200 tons/hour of low-temperature water. As early as July 2007, the environment-friendly refrigerant replacement technology project was established at the Jilin Petrochemical Carbide Plant and a full-scale technical demonstration and practice was conducted in the same year. This is also the first time in China that R123 has been identified as a refrigerant replacing R11 centrifugal refrigeration unit. Experimental project. Because there is no technical reference template and relevant experience in the country, there have been phenomena such as unsatisfactory separation of refrigerant and unit oil and failure to match the float valve in the experimental process. In order to overcome this series of problems, technical personnel conducted a series of inspections and studies for domestic R123 refrigerants for up to six months, and finally determined the ratio models. By May 2009, they had completed the replacement of three sets of FLZ1000 chiller refrigerants. After more than one year of safe operation and monitoring, the technical monitoring indicators fully meet the requirements, and they have been recognized by the Jilin Provincial Ministry of Safety and Environmental Protection, and the technical environmental protection certificate has been granted.
The water and air dual purpose series drilling rig is a multifunctional drilling rig that integrates water and air drills. This is the first one in China. The drilling rig adopts an AMT manual automatic transmission. Sensitive and convenient switching between positive and negative. Compared with hydraulic transmission, the power consumption is reduced by 35%, making it more efficient and energy-saving. The drilling rig has a fast speed and can be used in conjunction with a Mud Pump to solve the problem of difficult drilling with a soil gas down-hole hammer. The boring machine has high torque and can slide up and down. Deep hole drilling can be used for hard rock layers, gravel layers, and pebble layers below deep wells. Drill with a down-hole hammer. This drilling rig can be professionally engaged in drilling, monitoring wells, geothermal air conditioning drilling, diamond bit wired coring drilling, and engineering geological survey operations.
The main characteristics of the drilling rig:
1. The drilling rig is equipped with a hydraulic drill tower, hydraulic support legs, and a winch, and the power head can slide up and down. Hard rock can be used for DTH hammer drilling.
2. The drilling rig adopts a long stroke dual speed mechanism and mechanical power head, with a power head stroke of 3400mm, which is used to improve drilling efficiency and reduce the occurrence of blockage and burning accidents.
3. The drilling rig adopts dual oil pumps for oil supply. When feeding, a single pump is used, and when lifting the drill pipe, a dual pump combination is used; Low power loss and short auxiliary time.
4. The drilling rig has reserved some functional interfaces in the hydraulic system, which can be expanded according to the process requirements of different users.
Chlorine-free refrigerant replacement for chiller
On September 29th, from Jilin Petrochemical and Calcium Carbide Plant, China's first centrifugal chiller-free replacement technology for fluorine-free refrigerants was introduced and successfully applied at Jilin Petrochemical and Calcium Carbide Plant. A number of operational indicators have reached the international advanced level. This indicates that China has completely grasped the core technology of replacing and updating environmentally friendly refrigerants, and provided a successful example for the environmental protection reform of large-scale chillers in the domestic petroleum and chemical industries, and also eliminated the use of fluorine-containing R11 (CCl3F)-type refrigerants within the company this year. A pressing need.
