CSM Conditioning Equipments to overcome two-phase flow

CryoVent constantly removes vapor when the liquid in the pipeline is not in used. The static heat leaks will constantly evaporate the liquid in the pipeline into vapor, the vapor vent job to remove and exhaust the vapor to atmosphere in order to keep the pipeline always filled with liquid. It is sometimes known as keep-full device. It is important to estimate correctly the static heat leaks and system head loss to determine the right number of vapor vent devices required throughout the system. It is installed usually at the highest point of the main-riser pipe or end of header pipes or sub-lateral.

Degasser removes vapor in both conditions, when the liquid in the pipeline is used and not in used. When the liquid is in used, it flows through the degasser where its velocity reduces due to sudden increase in volume. Vapor is removed from 2-phase liquid stream by liquid decompression. It is important to estimate correctly the static heat leaks and head loss of the system to size up the right degasser capacity needed for the intended application.The degasser is usually placed in the middle of the pipeline or at POU.

Phase separator removes vapor from 2-phase liquid stream using the liquid decompression and volume expansion principle by stepping down the incoming liquid pressure. It has storage vessel range from 22 liters to 100 liters capacity. The liquid level and supply pressure are electronically modulated using electro-pneumatic control valves. It is frequently used as pressure step down device to reduce bulk tank pressure to the desired pressure at POU. The unit is supplied with a controller integrated with HMI for ease of pressure & level control setting. An atmospheric pressure control phase separator is capable to provide virtually a subcooled liquid at 1 atm. Atmospheric pressure control phase separator is critical equipment used in molecular beam expitaxy (MBE) application. CSM is one of very few privilege companies in the world possesing the knowledge to design, manufacture & deliver a close loop liquid nitrogen application for MBE system application.
