Keke Petrochemical Uses New Sealing Sampling Equipment

“This newly installed closed sampling device is both easy to operate and avoids direct contact with toxic and hazardous media when the operator samples.” On September 4, the Karamay Petrochemical Company, which is sampling 600,000 tons of continuous reformers annually The four joint workshop staff Nur Ai Zaiyu said.

It is understood that this kind of sampler has a very wide range of applications. Terminals for medium flow such as oil, gas, and sewage can be installed and installed. Wang Yang, who is responsible for installing the sampler, introduced that the sampling device for liquid sampling is a dual-valve valve group structure. When sampling is not required, the sample flows back into the process piping to form a loop, ensuring that the sample taken at any time is “fresh”. . More importantly, this sealed sampling device avoids the direct contact of operators with toxic media during the sampling process. The gas medium adopts cylinder closed sampling equipment and is very environmentally friendly.

“In the past, when operating personnel stood in front of the old-fashioned open sampling equipment, they had to wear a gas mask and sometimes they had to wear an air respirator when taking gas samples containing benzene, hydrogen sulfide, etc.” said Wang Yang.

Now, this closed sampling device is equipped with a specific sampling bottle. The operator only needs to insert the end of the sealing rubber bottle into the sampling needle port, and gently pull the sampling valve to complete the collection of an oil sample. The operation is very convenient.

Eight oil samples were collected in just six or seven minutes. In the past, such sampling was done for at least 20 minutes.

"If you put off the sample in the past, if the sampling valve does not close tightly, it can easily cause running, running, dripping or leaking of the oil. In winter sampling, the medium in the pipe is also prone to freezing," said Nur Ai.

Due to the circulating flow of the oil medium in the sampler, this sealed sampling device will not freeze the oil sample media in winter.

At present, Keke Petrochemical has used such sampling equipment in three new installations with annual 600,000 tons of continuous reformation, 1 million tons of delayed coking and 1.2 million tons of diesel hydrogenation and upgrading. In the next step, Keke Petrochemical will install such closed sampling equipment one after another.
