Does a ground torch require an additional liquid tank? Are there any relevant standard regulations?

Refer to section 2.0.1.4 of HG20570.12: A separation tank should be installed for each main flare exhaust pipe. If a separate liquid phase collection system is in place, or if fire rain cannot occur even under the worst emergency emission conditions, then it is not necessary to use a separation tank; instead, only one liquid collection pipe connected to the liquid phase collection system is sufficient. For reference only!

We have liquid separation tanks, water seal tanks, and flame arresters

It is recommended that you refer to SH 3009-2013

Nowadays, all torches need to be placed in a liquid separation tank; even if it’s a smaller one, one that is merely symbolic, it still has to be used

For torch systems, whether they are ground-based or high-altitude torches, a gas-liquid separation device is required. There are two main purposes: 1. To prevent fluctuations in the incoming gas conditions, which could lead to a significant decrease in the efficiency of liquid droplet sedimentation, thereby increasing the risk of a \"fire rain\" phenomenon or \"drifting rain\". 2. Recover the useful liquids carried by the flare gas, such as raw materials or finished products, solvents or fuel oils, etc., to reduce material consumption in production operations and generate economic benefits from the recovery of by-products.

If the flare system has multiple gas inlets and the operating conditions of each inlet are not stable, the temperature, pressure, and flow rate of the incoming gas can cause the flare gas velocity to fluctuate greatly, and it may even carry a significant amount of liquid. It is recommended to use a feather-leaf high-efficiency gas-liquid demisting and defoaming separator to improve separation efficiency and reduce the size of the separation tank as well as the associated capital costs. Based on the design experience of ground gas-liquid separation tanks for torch systems in various projects, the size of the separation tank shell required for using fan-type high-efficiency gas-liquid demisting separators is typically only about 60% of the diameter of the shells used in conventional mesh separators or gravity sedimentation separators. This not only significantly improves the separation efficiency but also greatly reduces the cost of the separation tanks. We once designed and supplied the surface separation tanks for a large-scale foreign LNG project for a well-known engineering company within the CNPC group. By using efficient vaned gas-liquid demisting and defoaming internals, the diameter of these equipment units was reduced from nearly 7 meters to 4.2 meters, while their length was decreased from 37 meters to less than 12 meters. The use of stainless steel for the tank shells helped the company save significant amounts on manufacturing costs, and the separation efficiency was greatly improved, which earned recognition and approval from both Western clients and domestic engineering companies.

I want it. A small ground torch fluid needs to be installed.
