Heat exchanger is one of the two important devices in oil refinery industry. Each type of VBOLT heat exchanger is accurately calculated by the engineer team.
1.Efficiency of heat exchanger determines oil recovery rate.
2.Reducing energy consumption.
3.Saving operating costs.
－HEAT EXCHANGERS CALCULATIONS:
The main basic Heat Exchanger equation is:
Q=UxAxΔTm=
The log mean temperature difference ΔTm is:
ΔTm=(T1-t2)-(T2-t1)=°F
Where:

－HEAT EXCHANGERS CALCULATIONS:
The main basic Heat Exchanger equation is:
Q=UxAxΔTm=
The log mean temperature difference ΔTm is:
ΔTm=(T1-t2)-(T2-t1)=°F
Where:
T1=Inlet tube side fluid temperature;
TemperutareiC
t2=Outlet shell side fluid temperature;
T2=Outlet tube side fluid temperature;
t1=Inlet shell side fluid temperature.
can be rearranged to become:
A=Q/(UxΔTm)=
Where:
A=Heat transfer area(m2)(ft2);
Q=Heat transfer rate (kJ/h) (Btu\h);
U=Overall heat transfer coefficient(kJ/h.m2.°C)(Btu/h°F);
ΔTm=Log mean temperature difference(°C)(°F).
And:
Ct=Liquid specific heat,tube side(kJ/kg° K)(Btu/lb°F);
Cs=Liquid specific heat,shell side(kJ/kg°K)(Btu/lb°F).
Waste oil refers to the waste oil that is replaced from various machinery, vehicles and ships. Lubricating oil due to external pollution in the process of use to produce a large number of gum, asphaltene, sulfur, nitrogen, oxygen compounds to reduce and even lose its due effect and be discarded, according to statistics, the global annual production of waste oil is about 45 million tons, the market value of more than 43 billion dollar, but because of its own economic value is abnormally low, it h... moreWaste oil refers to the waste oil that is replaced from various machinery, vehicles and ships. Lubricating oil due to external pollution in the process of use to produce a large number of gum, asphaltene, sulfur, nitrogen, oxygen compounds to reduce and even lose its due effect and be discarded, according to statistics, the global annual production of waste oil is about 45 million tons, the market value of more than 43 billion dollar, but because of its own economic value is abnormally low, it has always been in the "waste" status. And every year to get rid of it, it is dumped or burned. This is not only the problem of large-scale environmental pollution, but more importantly, it involves the global energy crisis.
So, is there a technology or equipment that can make waste oil and waste diesel "become" high-quality diesel, providing a new way to solve the environmental pollution problem of waste oil and save energy?
Vbolt engineer Jay led the team, after years of unremitting efforts, has overcome a number of recognized technical problems in the industry, the establishment of their own production line, the manufacture of waste oil recycling diesel double-stage intelligent control equipment.
Chongqing Vbolt Machinery Co., Ltd，the main products include waste Oil to base oil distillation machine,waste oil to diesel Recycled machine,discolorizeration & desulfurization machine and base oil solvent extraction plant.
