The SaveAs() method supports stream, so to get the ClosedXml workbook as a stream I use:

public Stream GetStream(XLWorkbook excelWorkbook)
{
    Stream fs = new MemoryStream();
    excelWorkbook.SaveAs(fs);
    fs.Position = 0;
    return fs;
}

And then for downloading the file:

string myName = Server.UrlEncode(ReportName + "_" + DateTime.Now.ToShortDateString() + ".xlsx");
MemoryStream stream = GetStream(ExcelWorkbook);

Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=" + myName);
Response.ContentType = "application/vnd.ms-excel";
Response.BinaryWrite(stream.ToArray());
Response.End();
