The invention relates to a high manganese austenitic iron-based alloy containing boron and a thermal processing method thereof. The alloy comprises the following chemical components of: 0.15-0.40% of C, 0.5-1.5% of Si, 8.0-14.0% of Mn, 15-22% of Cr, 1.5-3.5% of Ni, 0.3-0.55% of Nb, 0.4-0.5% of N+B and the balance being F2 and inevitable impurities. The normal temperature hardness of a cast alloy of the alloy melted by an electric furnace and shaped by centrifugally casting is up to 25-30 HRC; the room temperature extension strength is up to 700-720 MPa; the impact tenacity is up to more than 22 J/cm<2>; the corrosion resisting life is improved by 2.5-3 times more than a 316L stainless steel. Furthermore, the invention provides a thermal processing method for improving the corrosion resistance of the alloy, comprising the following steps of: completely solidly dissolving and separating secondary boride compounds in the issue via the high temperature solidly dissolving treatment and the annealing ...

The present invention discloses a heavy hydrocarbon removal unit for pipeline natural gas. The heavy hydrocarbon removal unit mainly comprises a heavy hydrocarbon adsorber, a regeneration gas heater, a heavy hydrocarbon and regeneration gas heat exchanger, a regeneration gas and heavy hydrocarbon separation tank and a high-pressure energy saver. The heavy hydrocarbon adsorber is arranged at the downstream part of a molecular sieve dehydration unit, comprises two heavy hydrocarbon adsorption beds, and is used for removing aromatic hydrocarbon, naphthenic hydrocarbon and long-chain alkanes with a carbon number greater than 6. The present invention further discloses a technological method for removing heavy hydrocarbon in the pipeline natural gas by applying the heavy hydrocarbon removal unit. Extra heavy components in the pipeline natural gas are removed by utilizing physical absorption at first, and then other heavy components are removed by utilizing condensation separation, so that efficient ...
