What is hot oil circulation?
1. n. [Well Completions] Circulation of heated fluid, typically oil, to dissolve or dislodge paraffin deposits from the production tubing. Such deposits tend to occur where a large variation in temperature exists across the producing system. See: production tubing.
What is thermal oil used for?
Thermal oil systems are used with bitumen derived products such as coatings for building materials/coatings and in road construction for maintaining the flowable state of the hot road mixture. The temperature for this application is typically between 170 and 200ºC.
What is hot oil unit?
A hot oil system is an independent source of utility for the unit operation equipment like ATFE, ANFD, SPDU etc. The unit can also be deployed whereby the unit process has to be taken under high temperature.
How much does heat transfer oil expand?
Oxidation. Oxidation happens in all organic heat transfer fluids, which react with air to form organic acids. This oxidation rate is lower at ambient conditions but increases rapidly with temperature and doubles every 20°F (11°C) over 200°F (93°C).
How does a hot oiler work?
Hot oilers have the ability to circulate any fluid you want to run through them. They have a suction and discharge line and the pump circulates the fluid that is in need of heating through the coil. A hot oiler is essentially a pressure truck with a heating unit on it and the heat is provided by burning diesel fuel.
Is Steam better than oil?
Hot Oil Heating is Safer Than Steam Hot oil heating is safer than heating processes involving steam for a number of reasons. Since the system does not require pressurization, the risk of a dangerous explosion is eliminated.
How does a hot oil heater work?
A thermal oil boiler fires through a helical coil and generates energy from the hot products of combustion. This, by heating the coil through radiation and convection. The coil heats the thermal oil or fluid that is pumped through the thermal oil boiler. The thermal oil heats coils in various types of heat users.
What kind of oil do electric motors use?
The grease consistency preferred for electric motors is normally NLGI 2 or 3, with a base oil viscosity of 100-150 cSt @ 40°C. Other characteristics to look for include good channeling characteristics, low oil bleed, oxidation resistance, anti-wear additives, and mechanical stability.
What is a hot oil pump?
Hot Oil Pumps. It works by circulating heat transfer thermal oils or hot water with very high temperature in the process system. These pumps are widely used for various food processing plants and industrial process applications where hot oils are used.
What is hot water pump?
A hot water recirculating pump is a type of pump installed in plumbing systems that pulls heated water from a water heater while simultaneously pushing cooled water in pipes to the heater.
What is an oil transfer pump?
Oil Transfer Pumps. This Oil Transfer Pump is designed to move oil or high viscosity fluids between a drum/barrel and a secondary container for transport or use. GPI 118000-9, 8 Gallons Per Minute gear oil transfer pump rated 12 VDC voltage has 1″ inlet/outlet connection use with thin to medium viscosity petroleum fluids.
What is a cooling pump?
Cooling water pump. Cooling water pumps are used for supplying heat exchangers with cooling water. Their flow rate varies depending on the heat flow to be dissipated. The required head is determined by the type of cooling system.
