Product Description

Helium Enrichment Unit using Membrane Technology

Safe Helium Concentration Unit Membrane-Based Helium Recovery Machine For Petrochemicals

Technical principle

Membrane permeation method utilizes the selective permeability of various gases such as helium, nitrogen, argon, methane, etc., through the membrane. Each gas exhibits different permeation characteristics, allowing for the extraction of helium from natural gas.

 

Product Description

LNG BOG Helium Recovery System

Taking LNG BOG as the raw material, the process involves multiple pretreatments and precleaning steps, including but not limited to oil removal, water removal, cryogenic separation purification, recooling, pressurization, drying, decarbonization, etc. The resulting gas mixture contains a higher concentration of helium (He) along with significant amounts of impurities such as methane (CH4) and nitrogen (N2). The process includes membrane separation for helium enrichment, PSA refinement, alloy helium separation,
TSA purification, and other steps to individually remove CH4, N2, and Ne, extracting high-purity helium products.

Integrated Utilization System for Natural Gas/Coalbed Methane/Shale Gas

Taking natural gas/coalbed methane/shale gas as raw materials, the process involves multiple pretreatments and precleaning steps, including but not limited to oil removal, water removal, cryogenic separation purification, recooling, pressurization, drying, etc. The resulting low-concentration He/H2 gas mixture contains a significant amount of impurities such as CH4 and hydrocarbons.

 

The process includes low-temperature fractional distillation, membrane separation for He/H2 concentration, PSA refinement for He/H2 purification, alloy He/H2 separation, TSA removal of Ne, etc., to individually remove CH4, N2, etc. The final result is the extraction of high-purity He, electronic-grade H2, liquid C2H6, LPG, and LNG (or pipeline natural gas).
