EVACUATION GP

We assist in the preparation of tank containers, accepted for temporary use, by minimizing the residues of the gas phase of the products in tare operation unders pressure. The possibilities for collecting the gas phase to zero (evacuation, vapor pumping out), exact quantity of evacuated vapors and the speed of such collection are determined in accordance to the type of gas provided for packing operations (ISO tank, tank container, cylinders) and the equipment used in providing services.

Based on physicochemical properties of compressed gases and liquefied (refrigerants, cooling agents, freons), at different ambient temperatures they are either in liquid or gaseous state. When the temperature of the environment is lowered, as a rule, the pressure drops, and when rising, it increases. Therefore, very often the buyers of refrigerants and other liquefied and compressed gases that purchase them for subsequent packaging (to smaller tare, gas fire-extinguishing units, etc.), or when using it as raw materials for production purposes, do not have the opportunity to take advantage of the full quantity of the gas. Losses with usage of standard pump-compressor equipment for the gas phase, as a rule, are 3-6% of the total mass of gas, which, with the high cost of raw materials, is a significant financial damage to the consumer.

By the definition of "loss" during the pumping is meant - the quantitative measure of gas in kilograms which appears, due to the formation of a residual quantity in the liquid and gaseous state, not only in the connecting pipelines, but due to the impossibility of the existing equipment to pumping-out the gas phase of the substance. A big mistake for consumers when working with clean gases is to squeeze out gas residues with, for example, nitrogen, as this leads to a deterioration in the quality of the pure raw materials and can cause irreparable harm to the cylinder operating at a lower pressure.
