In the hydrogenation units of petrochemical enterprises, a filtration and separation unit must be installed before the recycled hydrogen enters the compressor, in order to remove the solids and liquid contaminants carried by the recycled hydrogen. When selecting cyclic hydrogen compressors, many companies opt for the internationally renowned SOLAR TURBINES compressors, which impose high technical requirements on the inlet cyclic hydrogen filtration and separation units. I hope everyone will discuss the situation regarding the inlet filtration separators used in the recycle hydrogen compressors at their own companies.
We have previously provided the inlet filtration and separation units required to meet the stringent technical specifications for a circulating hydrogen compressor in a petrochemical project in China, as part of the design for Sola Turbines. Sola Turbines requires that this filtration and separation unit be installed in a skid-mounted configuration, equipped with instruments and valves of the specified brands.
The reason why Solara turbines are considered demanding is evident from one of their requirements: with a liquid content of 500 ppmw at the inlet of the cyclic hydrogen, the residual liquid mist in the outlet stream after passing through the filtration separator must be reduced to 0.001 ppmw. To meet this requirement, it is necessary to use polymeric coalescing filter element chambers of the highest precision level, in series with two-stage vane separation chambers. Otherwise, it is not possible to meet the technical requirement of keeping the liquid mist residue in the exhaust airflow at 0.001 ppmw.
The required separation efficiency for solid particulates is that β0.3 must be greater than 200. Clearly, to meet this requirement, it is necessary to use gas-solid separation internals with the highest separation precision available internationally.
The operating pressure and temperature must meet two conditions: 560 psig at 300°F, 630 psig at 200°F.
The gas flow rate also needs to meet two conditions: 214 ACFM, 300 ACFM.
The dirt load capacity requirement for the filter element in Solara turbines is: 580 grams @ 10 psid.
The gas phase composition of the recycled hydrogen is as follows: (mole%) H2, 57.5; CH4, 22.5; C2H6, 2; C3H6, 1; N2, 6; O2, 0.5; CO, 8.5; CO2, 2.
