Problems solved by technology

Subsequently, oil and gas recovery at crude oil terminals was steadily promoted along the coast, and more and more oil and gas recovery facilities were installed in port terminals, and the continuous operation of terminal oil and gas recovery facilities can basically meet the continuity of shipment, but the effect of use is uneven, and the energy consumption is relatively large. big
Existing technologies such as "a wharf oil and gas recovery device" (CN2013104309861) solve the problem of continuous operation of the device, but for chemical VOCs waste gas, because there is no spare cold field for deep cooling, it cannot realize continuous operation of the wharf for 24 hours
In addition, the existing oil and gas recovery facilities at the oil terminal have large oil and gas temperature fluctuations and relatively large energy consumption of the unit

Abstract

The invention discloses a tanker wharf oil gas recovery device which comprises an oil gas system, a refrigerating system and a control system. The shallow cooling heat exchanger and the deep cooling heat exchanger form a double-gas-path channel, and continuous operation of the oil tanker wharf oil gas recovery device is guaranteed; the technology that a single compressor controls a two-way cold field is further utilized, it is guaranteed that the cold field temperature fluctuation of the oil tanker wharf oil gas recovery device is +/-4 DEG C, and the energy efficiency is improved by 40% or above.

Description

technical field [0001] The invention belongs to the technical field of oil and gas recovery, in particular to an oil and gas recovery device for a tanker terminal. Background technique [0002] The construction of oil and gas recovery facilities at the terminal started late, and the actual operation experience is insufficient. Subsequently, the oil and gas recovery of crude oil terminals was steadily promoted in the coastal areas. More and more oil and gas recovery facilities were installed in port terminals, and the continuous operation of oil and gas recovery facilities at the terminals could basically meet the continuity of loading, but the use effects were uneven, and the energy consumption was relatively big. Existing technologies such as "a wharf oil and gas recovery device" (CN2013104309861) solve the problem of continuous operation of the device, but for chemical VOCs waste gas, because there is no standby cold field in cryogenic refrigeration, it cannot realize the...
