Abstract
A system and method for lubricating fluid flow apparatus utilizing a hydrate-reducing chemical.
Claims12
A hydrocarbon recovery method comprising recovering a mixture of oil and gas from a well;
- separating the oil from the gas;
- transferring the separated gas to a first unit for compressing the gas;
- activating the first unit for compressing the gas;
- transferring the separated oil to a second unit for pumping the oil;
- activating the second unit for pumping the oil;
- mixing a first quantity of a chemical with the mixture to minimize hydrate formation during the steps of transferring, compressing, and pumping;
- and passing a second quantity of the chemical to the units for lubricating the units.
4 more elements
A hydrocarbon recovery system comprising a separator for receiving a mixture of oil and gas and separating the oil from the gas;
- a first unit for compressing the gas;
- a conduit connecting the separator to the first unit to transfer the gas to the first unit for compressing the gas, a second unit for pumping the oil;
- a conduit connecting the separator to the second unit to transfer the oil to the second unit for pumping the oil;
- a conduit for passing a first quantity of a chemical to the mixture so that the chemical passes with the oil and the gas through the conduits and to the first and second units, respectively, to minimize hydrate formation in the conduits and the units;
- and a conduit for passing a second quantity of the chemical to the units for lubricating the unit.
