Can the laboratory in a chemical plant conduct pilot tests?

It seems not possible. You can establish a R&D center or a certification laboratory; that would make conducting experiments much easier.

Flammable and explosive? Are there any special equipment? Is there any pollution discharge?

It depends; it’s just for testing purposes, and there will be no profit-driven activities such as issuing test reports. I think that’s what it means

It mainly depends on the hardware and the properties of the raw materials used for testing. For example, if it involves substances that can be used to manufacture drugs, even just one of the raw materials required, it is necessary to submit an application to the public security authorities for approval. Another example is situations that may involve hazardous waste; in such cases, an environmental impact assessment is at least required. If it’s flammable and explosive, then that’s interesting; you have to register the building first, and there are a whole bunch of other things to take care of afterward. If you need an external testing and evaluation report, things become more interesting: first, prepare the four key documents; neither the person in charge nor the certificate holder may be missing, and all equipment must be available and registered. A bunch of things

I think there’s no problem, as long as it complies with relevant safety regulations and other requirements

It does not involve profit-making trading activities such as issuing test reports. The entire experiment consists of two steps: cracking (10–80 KPa) and hydrogenation (2–10 MPa). The dimensions of the experimental setup are approximately 2.5×1×1.8, with hydrogen being supplied from gas cylinders.

The operating environments of laboratories and pilot plants are different, as are the applicable standards. It’s fine as long as nothing goes wrong, but if an incident occurs, the responsibility is significant; therefore, they cannot be used interchangeably.

I agree with you. For laboratory pilot tests, there is no requirement to obtain approval or anything similar, but the facilities need to be set up in accordance with the relevant laboratory standards in order to meet the necessary conditions. There are also different usage requirements for various categories of chemicals. In short, it is necessary to first determine whether the laboratory complies with regulations, whether its facilities meet safety standards, and if there are any special requirements regarding the chemicals used, in order to conduct a comprehensive risk analysis and assessment. Then develop a basic plan and safety measures
