Problems solved by technology

[0005] However, the existing sampling system for sour natural gas is to neutralize the sour natural gas discharged during the sampling process (including the sour natural gas displaced from the steel cylinder and the sour natural gas discharged from the sampling pipeline without storing the steel cylinder). If the pipeline is directly discharged into the neutralization tank, the sulfur-containing natural gas will be neutralized with the neutralization solution in the neutralization tank and then directly discharged into the atmosphere. This neutralization and discharge method makes the neutralization pipeline discharge into the neutralization tank. The sulfur-containing natural gas in the tank is too concentrated, the sulfur-containing natural gas in the neutralization tank and the neutralization solution cannot fully contact and react, and the desulfurization effect is poor. It will cause pollution to the surrounding environment, which is not conducive to the safe and smooth development of sampling operations

Abstract

The invention discloses a sulfur-containing natural gas sampling system which comprises a neutralizing tank, a neutralizing solution is contained in the neutralizing tank, a neutralizing gas inlet pipeline extends into the neutralizing solution, and the end, extending into the neutralizing solution, of the neutralizing gas inlet pipeline is connected with a gas distributor capable of dispersing sulfur-containing natural gas into a plurality of small bubbles. Aiming at the particularity of sulfur-containing natural gas sampling, the gas distributor capable of dispersing sulfur-containing natural gas into a plurality of small bubbles is connected to the end part of the neutralizing solution extending into the neutralizing box from the neutralizing gas inlet pipeline so that the sulfur-containing natural gas discharged in the sampling process is in full contact reaction with the neutralizing solution in the neutralizing box; the desulfurization effect is good, the sulfur content of natural gas discharged into the atmosphere is low or even zero, and the system is environmentally friendly and beneficial to ensuring that sampling operation is safely and smoothly carried out.

Description

technical field [0001] The invention relates to a sampling system for gas detection, in particular to a sulfur-containing natural gas sampling system. Background technique [0002] The commercialization of natural gas requires desulfurization treatment, and the premise of natural gas desulfurization treatment is to measure the substances and content in natural gas, especially the sulfur content. The measurement accuracy of the substances in natural gas depends on the sampling technology. Reliable sampling of sulfur natural gas directly determines the measurement accuracy of sulfur content in natural gas. [0003] Sampling of sour natural gas is carried out in a sour environment, and there are risks of hydrogen sulfide leakage and hydrogen sulfide poisoning, which are mainly reflected in the replacement process of the sampling container-steel cylinder and the discharge of natural gas in the sampling pipeline. [0004] At present, the sampling of sour natural gas is carried o...
