ZhongNi a unique integrated Availability scope, including vacuum pumps, compressors and composite systems, industrial systems for a variety of petrochemical applications. Normally, according to the needs of users, ZhongNi can bring together multiple functions integrated systems, and provide technical advice ZhongNi proprietary.

Gas recovery
In the field of oil and gas industry, gas emissions into the atmosphere in both the upstream or downstream refining production, gas recovery are hydrocarbon gas tank recovery procedures. Vapor recovery can be removed by vacuum, compressed gas from the tank to achieve. Through the use of liquid ring pump can be recovered, liquefaction, and then using ethylene oxide gas. To this purpose or use in this process rotary compressor blades, including through the separator and gas condensate separation will be compressed gas to the sales line distribution.

Gas recovery
Gas recovery can be described as sewage systems or refining production of gas recovery. Because of its content, this is often thought of gas emissions. HC containing a lot of gas, these gases are usually must be incinerated.

Very often, some of the high-quality gas can be incinerated, these BTU gas has some residual value. Such gases, once were isolated and can be recovered from the low-pressure compressor and the pressure within the compressor piping. The reciprocating compressor maximum recovery of gas compression, power generation equipment to its compression, processing, and can be used to power a joint.

Here the application of the "change-waste-the concept of" recovery because most of the gas burned to be very economic, and to serve as a source of energy and income generation. The gas will be unnecessary burned down to a minimum, not only beneficial to the environment, but also resolve the issue of income and opportunities.


Gas Boost
Gas Boost including the use of natural gas will be sent to the booster compressor in the recovery process and reduce the possible use of the engine.


Enhanced oil recovery
Enhanced oil recovery of an upstream process, including the elimination of vacuum wells to ease pressure wells, the oil can flow more freely to enhance oil production. It also includes incidental gas is only incidental or of wellhead gas recovery, recycling the same time, when a recovery, oil / gas separator, usually in oil-for.
Stability of oil
Through the use of liquid ring pump or compressor from the actual stability of dissolved gases and steam pressure can be a stabilization of crude oil processing. According to the environmental temperature changes, through the elimination of the tank vacuum and compression of the lower vents to achieve, which can improve the safety of the tank.


Vacuum distillation of crude oil
Through the atmospheric distillation or vacuum distillation, processed fuel, made from gasoline and other hydrocarbon fuel.

Such usage including crude oil distillation tower of vacuum equipment. Vacuum heat and the comprehensive role of the different boiling point, oil separation into different components. Its purpose is extracted lighter elements, such as gasoline. Vacuum distillation is higher than atmospheric distillation efficiency.


Exhaust compression
Crude oil distillation towers and other equipment from the refining condensate light hydrocarbon gas is not collected in the ordinary container, and through pipeline from burning out, or into the compressor. According to the exhaust pressure of the compressor with a value of the combustion exhaust compression, and its combustion to recover energy. This process usually very short, energy recycling, environmental protection is very important.



Steam recovery / gas boost
This differs from exhaust recovery, steam recovery relatively fixed, unchangeable. Typical applications for the collection tank vent. The vacuum of a tightly controlled to protect the tank. Under normal circumstances, exhaust pressure is relatively low. Gas back to the regular procedures, or for liquefaction, and returned to the storage tank.


Filtration / except December
In addition to filtering or December is the collection of hydrocarbon-oil production in December ingredients. Get rid of the oil in December, the oil can improve the quality and applicability. Sustained Elimination liquid ring pump may contain frozen with MIBK nitrogen disc or drum-shaped filter vacuum. If you need a higher degree of vacuum, it will install mechanical fan and liquid ring pumps, joint role.


Exhaust Recovery
The torch gas / tail gas recovery unit, ZhongNi liquid ring compressor is a very good choice. One of the main reasons is that the compressed gas and are basically the temperature, the temperature of about *0 degrees Celsius to about *0 degrees Celsius. This would avoid the use of other types of compressors may have precluded the high temperature exhaust gas compressor in a polymerization such phenomena.


Polyester Production
In polyester production, the necessary response to the vacuum tower can be used by the steam ejector and FUTEN liquid ring vacuum pump system comprising compound to obtain. With other applications difference is that here can be directly used ethylene glycol (EG) as a vacuum pump working fluid for the entire vacuum system operation.


PVC production
In polyvinyl chloride (PVC) production process, in response to the residual vinyl chloride monomer (VCM) was first ZhongNi liquid ring vacuum pump out and put into the tank; Through ZhongNi pressurized liquid ring compressor to 0.7MpaA about stored in a liquid form VC recovery tank to be a Progressive Step response.


Chlorine packaging
In the chlor-alkali plant chlorine packaging technology, using high pressure ZhongNi export liquid ring compressor, can greatly reduce costs, and avoid environmental pollution.


Other
ZhongNi vacuum pumps, compressors and vacuum unit (including corrosion resistant series) in the petrochemical / chemical industry is widely used, far more than the few.
